Description

HYPER TEXT MARKUP LANGUAGE DEVELOPMENT TOOL
TECHNICAL FIELD OF THE INVENTION
This invention relates generally to the field of computers, and more particularly, to a Hyper Text Markup Language development tool.
BACKGROUND OF THE INVENTION
The Internet is an interconnection of computers located throughout the world. The Internet allows businesses, groups, and individuals to communicate and conduct business electronically. One application which is supported by the Internet is the World Wide Web (tne "Web") . The Web comprises a number of computer servers ("servers") containing information which may be accessed by any of a number of users operating an appropriate computer ("client"), such as a personal computer, connected to the Internet. The information available on the Web is typically in the form of web pages. The term "web page" is used herein to mean any computer file capable of being provided through a computer network to a client, processed, and then displayed. An increasing popularity of the Web m recent years has spawned an entire industry for the development of web pages. That is, many people, generally known as web page designers, are now n the business of creating web pages for others who wish to establish a presence on the Web.
Web page designers use a descriptive language known as Hyper Text Markup Language (HTML) and scripting languages, such as JAVASCRIPT, to develop web pages that may be displayed at a client. HTML supports the formatting of documents, the addition of graphics to such documents, and hyperlinks to other documents. An HTML document comprises text which has been "marked up" with tags to specify the document's structure and formatting. These tags, which comprise instructions enclosed in angled brackets, are inserted ust before, or before and after, the text affected. Software at a client interprets the tags and text of an HTML document to render or display a web page. A number of tools have been created m recent years to assist web page designers in developing HTML documents from which web pages can be rendered. These prior development tools, however, have suffered from numerous problems. For example, one prior development tool operated like a word-processor so that a web page designer only saw information as it would appear on a rendered web page—the HTML tags were invisible to the designer. For web page designers who were not very knowledgeable of HTML, this prior development tool was not suitable as a tutorial of HTML. In another prior HTML development tool, formatting tags could be generated by pressing certain buttons on a WINDOWS-type graphical user interface (GUI). When generated, however, these formatting tags would appear at the end of all the textual content of an HTML document. Because a user was required to copy and move the tags to their appropriate locations throughout the document, this prior tool was inconvenient .
SUMMARY OF THE INVENTION
In accordance with the present invention, the disadvantages and problems associated with prior HTML development tools have been substantially reduced or eliminated.
According to an embodiment of the present invention, a system is provided for developing Hyper Text Markup Language (HTML) documents. The system includes an interface having an editing panel and a viewing panel simultaneously displayed. The editing panel receives content information and format information. The viewing panel functions to display a web page. A processor, coupled to the interface, generates or modifies an HTML file m response to the content information and format information. The processor further interprets the HTML file m order to render the web page.
According to another embodiment of the present invention, a method is provided for developing HTML documents. In the method, an editing panel and a viewing panel are simultaneously displayed. Content information and format information are received at the editing panel. An HTML file is generated in response to the received content information and the format information. The generated HTML file is interpreted in order to render a web page corresponding to the generated HTML file. The rendered web page is displayed on the viewing panel.
Important technical advantages of the present invention include an HTML development tool comprising an editing panel and a viewing panel, which are simultaneously displayed to a user. The editing panel can be used to generate HTML tags throughout a textual document, these tags being visible to the user. The viewing panel snows the web page which may be rendered from the marked-up textual document. Because the marked- up textual document and the rendered web page are simultaneously presented to the user, the present invention may function as a tutorial for users who are not extremely knowledgeable of HTML. Another technical advantage of the present invention, includes providing a graphical user interface (GUI) have a plurality of buttons, lists boxes, and/or other interactive devices which can be used to generate HTML tags at appropriate locations throughout a textual document. Consequently, a user is required neither to manually type in such tags nor to copy and move tags to appropriate locations throughout the textual document. Accordingly, the present invention facilitates the development of an HTML document. Other important technical advantages are readily apparent to one skilled in the art from the following figures, description, and claims.

Turning first to the nomenclature of the specification, the detailed description which follows is represented largely in terms of processes and symbolic representations of operations by conventional computer components, such as a central processing unit ("CPU") or processor associated with a general purpose computer system, memory storage devices for the processor, and connected pixel-oriented display devices. These operations include the manipulation of data bits by the processor and the maintenance of these bits within data structures resident n one or more of the memory storage devices. Such data structures impose a physical organization upon the collection of data bits stored within computer memory and represent specific electrical or magnetic elements. These symbolic representations are the means used by those skilled in the art of computer programming and computer construction to most effectively convey teachings and discoveries to others skilled in the art. For the purposes of this discussion, a process, method, routine, or sub-routine is generally considered to be a sequence of computer-executed steps leading to a desired result. These steps generally require manipulations of physical quantities. Usually, although not necessarily, these quantities take the form of electrical, magnetic, or optical signals capable of being stored, transferred, combined, compared, or otherwise manipulated. It is conventional for those skilled in the art to refer to these signals as bits, values, elements, symbols, characters, texts, terms, numbers, records, files, or the like. It should be kept m mind, however, that these ano some other terms should be associated with appropriate pnysical quantities for computer operations, and that these terms are merely conventional labels applied to physical quantities that exist within and during operation of the computer.
It should also be understood that manipulations within the computer are often referred to in terms such as adding, comparing, moving, or the like, which are often associated with manual operations performed by a human operator. It must be understood that no involvement of the human operator may be necessary, or even desirable, m the present invention. The operations described herein are machine operations performed in conjunction with the human operator or user that interacts with the computer or computers.
In addition, it should be understood that the programs, processes, methods, and the like, described herein are but an example of one implementation of the present invention and are not related or limited to any particular computer, apparatus, or computer language. Rather, various types of general purpose computing machines or devices may be used with programs constructed in accordance with the teachings described herein. Similarly, it may prove advantageous to construct a specialized apparatus to perform the method steps described herein by way of dedicated computer systems with hardwired logic or programs stored in non-volatile memory, such as read only memory (ROM) .
Referring now to the drawings, FIGURE 1 illustrates a system 10 for developing HTML documents, according to an embodiment of the present invention. Development system 10 includes an interface (I/F) 12 for inputting, retrieving, and forwarding information. The functionality of interface 12 can be performed oy one or more suitable input devices, such as a keypad, touch screen, input port, pointing device (e.g., mouse), and/or other device that can accept information, and one or more suitable output devices, such as a computer display, output port, speaker, or other device, for conveying information associated with the operation of development system 10, including digital data, visual information, or audio information.
Interface 12 receives content information 14, format information 16, and instructions from a user of development system 10. Content information 14 may comprise textual information (e.g., letters, numbers, words, alpha-numeric combinations, symbols, and the like) which a user desires to display on a web page for any of a number of reasons, such as to advertise a product or service, promote discussion with others, or provide information to people "surfing" the Internet. Format information 16 comprises HTML markup information in the form of HTML tags. HTML tags are typically instructions enclosed in angled brackets which are inserted or added to textual information. These tags identify parts of a web page such as headers, footers, bulleted lists, body text, on-screen forms, fill-m text boxes, option buttons, radio buttons, drop-down list boxes, images to be displayed, hypertext links, colors, fonts, and various other formatting concepts. HTML tags may be included in the following four categories: (1) formatting tags which create paragraphs, tables, italics, bold face text, other format-related attributes; (2) structuring tags which establish the title, body, and headings of web pages as well as the sequence of or relationships between pages; (3) hyperlink tags specifying which elements on the page are hyperlinks to other pages, and where the links go; and (4) meta-content tags which describe the overall contents and structure of the document for purposes of navigation, indexing, categorization, and citation.
The instruction received via interface 12 may be entered by a user to, for example, generate, modify, or remove content information 14 and format information 16. As shown and descπoed below in more detail with reference to FIGURE 2, interface 12 may comprise a development screen m which an editing panel and viewing panel are simultaneously presented to a user of development system 10. Content information 14 and format information 16 are entered by and visible to a user on the editing panel. Instructions can be received at the editing panel to generate, modify, or remove content and format information. A web page (which results from the rendering of an HTML document created from the combination of the content information 14 and format information 16, as described herein) can be displayed to a user on the viewing panel.
A generate module 18 is coupled to interface 12. The functionality of generate module 18 may be performed by a processor, such as a main-frame, file server, workstation, or other suitable data processing facility running appropriate software, such as, for example, NAVIGATOR 3.0. Generate module 18 functions to generate one or more HTML documents or files 20 in response to the content information 14, formatting information 16, and associated instructions received from a user via interface 12. Each HTML file 20 comprises textual information with HTML tags distributed throughout. Each HTML file 20 can be used, either alone or in combination with other HTML files, to generate a web page which may be displayed at a suitable site, such as a client.
An HTML file memory 22 is coupled to generate module 18. HTML memory 22 may reside in a suitable storage medium, such a random access memory (RAM) , read-only memory (ROM) , disc, tape storage, or other suitable volatile and/or non-volatile data storage system. HTML file memory 22 can be a relational data base. HTML file memory 22 receives, stores, and forwards HTML files 20 generated by generate module 18. These HTML files 20 can be retrieved from HTML file memory 22 as needed to generate corresponding web pages . Web pages can be embellished with graphics, and in some cases, with animation and sound. A render module 24 is coupled to HTML file memory
22. The functionality of render module 24 can be performed by a processor, such a main-frame, file server, work station, or other suitable data processing facility running appropriate software, such as, for example, an HTML browser. This processor may be the same or separate from the processor which performs the functionality for generate module 18. Render module 24 is operable to retrieve the HTML files 20 generated by generate module 18 and stored within HTML file memory 22. For each HTML file 20, render module 24 functions to generate or render a corresponding web page by interpreting the textual content and formatting tags of the HTML file 20. The web pages rendered by module 24 may be in the form of displays 26. In one embodiment, render module 24 may comprise a suitable web browser application for interpreting the HTML files 22. A web browser is a computer program that allows a client to exchange information with the Internet. Any of a variety of web browsers are available, sucn as NETSCAPE NAVIGATOR, MICROSOFT EXPLORER, NCSA, MOSAIC, and others that allow users to conveniently access and navigate the Internet. The standard functions of a browser are to manage the connection between the client and the network, support the transfer of data therebetween, and interpret and display the data through a graphical user interface (GUI) . To accomplish this, browsers may download and interpret information from servers. Because of the interaction with servers, render module 24 may be coupled to the Internet via a connection 25, which can be any suitable connection which supports communication, such as the transfer of data, between development system 10 and the Internet. For example, connection 25 may include any one or a combination of an Integrated Services Digital Network (ISDN) communications line, a hard-wire line, a fiber-optic line, a telephone link, or any other suitable means for communicating between system 10 and the Internet. Render module 24 reads the tagged textual content of an HTML document to provide formatting for the same m a corresponding web page, which is presented to a user m the form of a display 26. The render module 24 formats the various parts of an HTML file 20 for on-screen display as directed by the HTML tags.
Render module 24 can be a forms-capable browser, meaning that it is able to interpret HTML code which provides forms, including fill-in text boxes, option buttons, drop-down list boxes, radio buttons, and the like. Render module 24 may also be a script-enabled browser, meaning that it is able to interpret HTML- formatted documents that include embedded script within the HTML code. Such embedded script is provided to a web browser at the client for enhanced processing at the client. The embedded script may be provided in JAVASCPIPT format or any other scripting language format that is provided to a web browser at a client for enhanced processing. Development system 10 may operate on one or more computers, shown generally as computer 28. Computer 28 maintains and executes the instructions to perform the receipt of content and format information, the generation and storage of HTML files 20, and the rendering of the HTML files 20 to produce corresponding web pages which are presented as displays 26. Computer 28 includes an input device 30, such as a keypad, touch screen, pointing device (e.g., mouse) or other device that can accept information. An output device 32 conveys information associated with the operation of development system 10, including digital data, visual information, or audio information. Both input device 30 and output device 32 may include fixed or removal storage media, such as magnetic computer disc, optical disc, CD/ROM, or other suitable media to both receive output from and provide input to development system 10. The input and output devices support the implementation of interface 12. One or more processors 34 and their associated memories execute instructions and manipulate information in accordance with the operation of development system 10 described herein. Processor 34 may support generate module 18 and render module 24. Computer 28 may also include or be coupled to any one or more peripheral devices, such as a modem, a printer, speaker, or the like, which provide or support additional functionality for development system 10. Computer 28 may be implemented using virtually any type of computer operating under the control of a suitable operating system, such as MS-DOS, Macintosh OS, WINDOWS NT, WINDOWS 95, OS/2, UNIX, XENIX, and the like.
The present invention contemplates that computer 28 may function m some respects both as a client, which has a browser to receive and interpret HTML documents, and as a server, which stores HTML documents for retrieval via the Internet.
FIGURE 2 illustrates an exemplary development screen 36 generated by system 10 shown m FIGURE 1. Screen 36, which may be a graphical user interface, can be used to input, view, modify, or delete information relating to, or contained within, a particular HTML file 20.
As shown, development screen 36 comprises an editing panel 38 and a viewing panel 40 which are displayed simultaneously. Each of editing panel 38 and viewing panel 40 includes one or more fields for viewing, inputting, selecting, or modifying information. At least a portion of these fields can be implemented as buttons, list boxes, or any other suitable WINDOWS-type operatives for viewing or inputting information. For example, list boxes present a user with a selection list for inputting information. Other fields may require that information be input by keying or typing. Still other fields can be configured to default to predetermined default items. Other fields can be managed by development system 10.
Editing panel 38 may include a window 42 for input or receiving content information 14 and/or format information 16. As stated above, content information 14 may comprise textual information which a user desires to display on a web page. This content information may be m the form of letters, numbers, words, alpha-numeric combinations, symbols, and the like. In one embodiment, content information 14 may be entered into window 42 by typing such information into a keyboard. Format information 16 may take the form of tags--ι.e., instructions enclosed within angled brackets. As described herein, the tags can be added or inserted throughout the textual content utilizing any one or more of the other fields of editing panel 38.
In particular, a plurality of formatting fields may be provided on editing panel 38. Each of these formatting fields may comprise a pull-down menu, a list box, a button, or any other suitable windows-type input device for inputting or viewing information. Preferably, a user is able to interact with these devices using a suitable pointing device, such as a mouse, in order to generate or input format information 16, which appears m window 42 in the form of HTML tags. As shown, the formatting fields include a format field 44, a table field 46, a color field 48, a bold face field 50, an italics field 52, an underline field 54, a heading field 56, and a footer field 58. It should be understood that these fields are provided by way of example only. Thus, in other embodiments, any other suitable formatting fields can be provided in combination with, or instead of, any or all of the previously listed formatting fields on editing panel 38.
Format field 44 may comprise a pull-down menu which presents a user with a list of various format preferences for the text of the content information 14 m window 42. This includes font preferences (e.g., Courier, Roman, Times New Roman, Onyx, etc.), font size (e.g., 8 point, 10 point, 12 point, etc.), justifications (e.g., left, right, center), margins, typesetting, and the like. Table f_ eld 46 can be used to create a table for the content information 14 within window 42. Table field 46 may comprise a pull-down box specifying a number of preferences to generate such table. Color field 48 may include a pull-down box specifying a nu oer of color choices for the text within window 42. When any of the preferences of format field 44, table field 46, or color field 48 are selected, development system 10 will generate appropriate HTML tags within the text shown in window 42.
Bold face field 50 comprises a button which is used to create HTML tags for bold-facing text within window 42. Likewise, italics field 52 may comprise a button which is used to generate appropriate HTML tags for italicizing the text. Underline field 54 may include a button is used to generate HTML tags for underlining selected text m window 42. Heading field 56 and footer field 58 are provided to generate HTML tags for headings and footers, respectively, for the text shown within window 42.
As shown, a view field 60 may be also be provided on editing panel 38. View field 60 functions to initiate the creation or modification of an HTML file 20 comprising the content information 14 and format information 16 contained in window 42. View field 60 may also function to invoke a suitable browser application, such as that of render module 24, to interpret the HTML file 20 so that the corresponding web page may be rendered or displayed as a display 26. In an alternative embodiment, however, editing panel 38 may not include any view field 60 at all. Rather, the generation of an HTML file 20 and the invocation of a browser application to interpret the file may occur simultaneously with the receipt of content and/or format information.
Viewing panel 40 functions primarily to present a web page to a user m the form of a rendered display 26. This web page corresponds to the HTML file 20 created or modified in the operation of editing panel 38. In particular, after an HTML file 20 has been created/modified utilizing editing panel 38, the HTML file is interpreted by the browser application to produce display 26 on viewing panel 40. In operation, development screen 36 is presented to a user of development system 10. The user may interact with editing panel 38 to create and/or modify an HTML file 20. Content information 14 is entered into window 42, for example, by typing on a keyboard. Format information 16 is added to the displayed content information 14 using any of the formatting fields 44-58 provided on editing panel 42. Preferably, to accomplish this, the desired text is "highlighted" or selected by the user using a suitable pointing device (e.g., mouse). One or more of the formatting fields is then selected in order to generate appropriate HTML tags either ust before, or before and after, the selected text. The present invention contemplates that a user can also insert HTML tags throughout the text m window 42 by typing the tags using a keyboard, such as the one by which the text is entered as described above. After a user has entered or modified the text and HTML tags m window 42, the user may select view field 60 in order to generate or update an associated HTML file 20. The selection of view field 60 also invokes the browser of render module 24 to interpret the HTML file 20 so that a corresponding web page is rendered or displayed in viewing panel 40 of development screen 36.
FIGURE 3 is a flow chart of an exemplary method 100 for developing an HTML document, according to an embodiment of the present invention. In one embodiment, method 100 corresponds to the operation of development system 10 shown and described with reference to FIGURE 1. During the steps of method 100, a user may interact with development system 10 via a suitable interface, such as exemplary development screen 36 shown m FIGURE 2. Method 10° is initiated m order to create a new HTML f le 20 or modify a previously created HTML file 20. Method 100 begins at step 102 where development system 10 is initialized. Each of editing panel 38 and viewing panel 40 may be initially presented to a user with a suitable message, such messages being simultaneously or consequentially displayed. In one embodiment, window 42 (of editing panel 38) and/or viewing panel 40 contains instructions for the operation of development system 10, such as, for example, the use of development screen 36. In an alternative embodiment, no initialization message is presented to the user. The user may choose to create a new HTML file 20 or, alternatively, to modify an existing HTML file 20. If the latter is chosen, generate module 18 retrieves the appropriate HTML file 20 from HTML file memory 22. After initialization, development system 10 is ready to receive information and instructions from the user.
Thus, at step 104, development system 10 receives content information 14 and format information. This information may be entered into editing panel 38 (of development screen 36) by the user via interface 12, which, m one embodiment, may comprise both a keyboard and a pointing device. Specifically, content information 14 is typed m to window 42 of editing panel 38 using the keyboard. Format information 16, in the form of HTML tags, may be inserted throughout content information 14, for example, by highlighting the desired content information 14 using the pointing device and then selecting from formatting fields 44-58.
At step 06, as content information 14 and format information 16 is being entered, or afterwards, generate module 18 generates a new HTML file 20 or modifies an existing HTML file 20 in response. Such HTML file 20 is stored in HTML file memory 22, for example, as it is being created or modified. The HTML file 20 corresponds to a web page, which can be displayed in the form of a display 26.
At step 108, development system 10 determines whether view field 60 on editing panel 38 has been selected by a user. If view field 60 has been selected, render module 24 retrieves the HTML file 20 from HTML file memory 22. At step 110, render module 24 interprets the content information 14 and format information 16 within HTML file 20 in order to render a corresponding web page in the form of a display 26. This display 26 is presented to the user on viewing panel 40 of screen 36. Development system 10 then moves to step 112. On the other hand, if it is determined at step 108 that a user has not selected view field 60, then system 10 skips the step of rendering a display 26 and moves directly to step 112.
It should be understood that in an alternative embodiment editing panel 38 does not include a view field 60, in which case, method 100 does not include step 108. The rendering of a corresponding web page occurs simultaneously with the receipt of content and format information at step 104 and/or the generation of an HTML file 20 at step 106.
At step 112, it is determined whether the user has elected to end this session for developing an HTML file 20. If the user has not elected to end the session, development system 10 returns to step 104 where additional content and/or format information is received at interface 12. Otherwise, if it is determined that the user has elected to end, then method 100 ends. Development system 10 may repeat steps 104-112, during which a user alternately (1) enters information on editing panel 38 to generate or modify the HTML f le 20, and (2) views a display 26 for a corresponding weo page on viewing panel 40. All HTML tags which are generated and inserted into the textual information are visible in window 42. Display 26 shows how the HTML tags support the formatting and layout of the textual information in the resultant web page. From the above, it can be seen that the system and method of the present invention can be utilized as a development tool for developing HTML files 20 and resultant web pages. Furthermore, the system and method may serve as a tutorial for teaching users HTML markups. Although the present invention and its advantages have been described in detail, it should be understood that various changes, substitutions, and alterations can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
