The basic idea of the present invention is: After the user makes a web request through the mobile phone browser, the keyword can be set in advance, and the mobile phone browser returns the webpage script information when receiving the webpage script information, and returns the keyword pair before displaying the webpage to the user. The webpage script information is matched, and the webpage content including the keyword is presented to the user in a display manner different from other webpage script information, so that the user quickly locates the content of interest on the screen of the mobile phone. The invention is greatly convenient Mobile phone users locate and ingest information of interest to them. The invention greatly facilitates the positioning and ingestion of the information of interest to the mobile phone user.

The present invention will be further described in detail below with reference to the accompanying drawings.

FIG. 1 is a flowchart of a method for quickly locating effective information by a mobile phone browser according to the present invention. As shown in FIG. 1 , the method for quickly locating effective information by the mobile phone browser of the present invention includes the following steps:

Step 101: The mobile phone user sets a keyword of interest, such as "Yao Ming", in the browser. At the same time, enter the Uniform Resource Locator (URL) in the tab bar of the mobile browser, and the browser encapsulates it in the header information of the Hypertext Transfer Protocol (HTTP) and sends it to the domain name server ( DNS, Domain Name Server) server.

Step 102: The mobile browser receives the information returned from the DNS (including the IP address of the network to be accessed).

Step 103: The mobile browser sends a browsing request to the Internet through the wireless link to the IP address returned according to the DNS.

Step 104: The mobile browser caches the webpage script information returned by the internet network, and constructs a tag tree according to the script tag and the attribute.

Step 105: The mobile browser traverses the parsed content. When finding the content related to the set keyword, such as "Yao Ming" in this example, the browser specializes the content including "Yao Ming", such as bold , change the font color, enlarge the font, and set it to the sport mode.

The processing of keywords in step 105 can be implemented in two ways: one is to analyze the network script to construct the tag tree, and when the content related to the keyword is retrieved, the label and the attribute are replaced and added, and the application is performed. The dissimilarity of the label performs a special treatment of the keyword. The second implementation method is to find the content related to the keyword by searching for keywords in the entire page after the network script is parsed, and then specializing it. This is described in detail below. The specific implementation of two keyword processing methods.

The first implementation of the keyword processing of the present invention is synchronized with the lexical analysis of Hypertext Markup Language (HTML). When receiving HTML data in the cache area, it is parsed into a specific data structure. The World Wide Web Consortium (W3C) has developed a Document Object Model (DOM) for programming interfaces to standard HTML and Extensible Markup Language (XML) documents, which define HTML or XML. The logical structure of the document and how to access it. It defines the logical structure of a document as a forest of one or more trees. With DOM, programmers can build, traverse forests, add, delete, and modify forest nodes and content. The lexical analysis method on which the present invention is based is also developed based on the DOM method. When dealing with HTML text, there are three categories, non-HTML code, whitespace characters, tags, and text (word). It is divided into annotation and non-annotation labels, and the detection and processing of labels is the key to lexical analysis. The keyword processing method of the present invention comprises the following steps:

Start parsing the HTML (or XML) script, if the first character encountered is '<, and there are subsequent characters, the subsequent characters are letters or one of "! /?", indicating that it is a label, or Is an HTML comment. If it is a comment, skip these comment strings until ">" is encountered, move backwards, and then determine the following label, loop the above operation until a valid ">" is encountered. The next thing to do is to parse the tag. The present invention defines a function such as html_process to process the resulting HTML tag element, search for whether the current element node contains a keyword, and if it contains a keyword, the corresponding tag replacement will contain the keyword. The label element is replaced with a bold label form. The so-called eye-catching label form is to modify the attribute value of the label so that it is displayed differently than the normal label, that is, the label that does not match the keyword or the label in the web content that does not include the keyword, specifically, compare The easy-to-implement method includes thickening the display content corresponding to the label, changing the color, enlarging the font, and adding a floating characteristic, so that the content corresponding to the label matching the keyword displays a display manner different from the content corresponding to the common label. Israeli The user quickly locates the content of interest on a small mobile phone screen, greatly improving the user experience.

The second implementation of the keyword processing of the present invention includes: By combining the characteristics of the HTML document and the display characteristics of the display device, the present invention displays the display content of each display element (determined by the content corresponding to the label) and the logical display position (ie, in an H. The combination of the display coordinates on the display device for infinity and the display style (determined by the label) is the unity of content and display. The present invention designs a Html-note type data structure. When performing tag processing, the tag nodes are created in a linked list according to the order of display, so that after processing, each node of the linked list is an element of the original HTML document, and Each node contains both display content information and display location information, and organically combines the logical display position and content of each display element. The construction principle of the linked list is: read the HTML source code in turn, and each time a new label mark is encountered, that is, the start character of the label '<' is encountered, then the processing of the previous label and its related display text is performed, that is, according to the logo And attributes to calculate the display characteristics of the display content attached to it, mainly including the logical position of the display, the displayed font, color settings, if there is a hyperlink, there should be hyperlink information. After this processing, it is linked to the Html-note type linked list, and the link order of the linked list is related to the order of display. When all the web scripts are parsed (the linked list is constructed) and the web page is displayed, all the linked list nodes are traversed, and the current node's data (data) field (display content) is searched for keywords, such as containing keywords combined with the label. The display position of the element, the current node element is specialized by calling the application interface function. The specific Html_note element is defined as follows:

Struct Html—note /* element structure; */

{

Int xstart, ystart; /* element displays the starting point of the content and coordinates; */ int xend, yend; /* element displays the end point logical coordinates of the content; */ char type; /* element displays the type of content (by the flag Decision); */

Char align; / * element display content alignment is determined by the property, such as BOTTOM (bottom alignment), TOP (top alignment), etc.; */

Char *data ; /* pointer points to the display content of the element */

Unsign char R, G, B; /* element display content display color */

Struct Html— note *headPtr; /*H Head pointer to Atom list; */ struct Html— note *linkr; /* Since the content of some elements is a label or element, use this pointer to point to such content; The pointer is NULL; */

Struct Html note *Prevatom; /* pointer to the previous element of this element; */ struct Html note *nextatom; /* pointer to the next element of this element; */ int, ptrAnimatedGIFID; /* pointer to GIF animation (if This element does not display NULL); */

Char *szTagetFrameName; /* pointer points to a related link to this element (no Null), mainly used for tags <a href:=" ">; */

}

Step 106: The mobile browser renders the page according to the label tree, and reduces the webpage to be displayed according to the size of the screen of the mobile phone, and displays it on the screen of the mobile phone.

Step 107: When the user moves the cursor on the screen of the mobile phone, a rectangular block diagram indicating the visible range is displayed. If there is content related to the set keyword in the rectangular block diagram, the system will enlarge the content to the user. This step combined with step 5 will greatly facilitate the user's browsing and improve the efficiency of browsing the webpage.

The invention can make the webpage content that the user cares about and the ordinary webpage content present different expression forms, and is convenient for the user to quickly locate the effective information in the small-sized mobile phone browser, and has certain practical value. At present, the processing power of mobile phones is still relatively limited. The mainstream mobile browsers put the network content download module on the proxy server, and the proxy server then filters and compresses the network content to make it suitable for the screen browsing of the mobile phone.
