Description

Method and system for converting HTML (hypertext markup language) file into Word file

Technical Field

The present application relates to communications technologies, and in particular, to a method, a system, an apparatus, and a storage medium for converting an HTML file into a Word file.

Background

The hypertext markup language (Hyper Text Markup Language, HTML) formatted file is a file browsed on a global wide area network Web browser. HTML is a markup language that displays text, graphics, animation, sound, forms, links, images, and the like by markup instructions. HTML plays an important role in the rapid development of Web browsers, and plays an important role. However, with the penetration of web applications, particularly electronic commerce applications, the shortcomings of HTML soon manifest themselves: HTML does not allow application developers to define custom tags for specific application environments, but can only be used for information display. HTML can set the text and picture display modes but has no semantic structure, i.e., HTML display data is by layout rather than semantic. However, with the development of network applications, various industries have different demands on information, and these different types of information are not necessarily displayed in the form of web pages, so that the conversion of HTML files into Word files is a necessary link in many works.

The current mainstream scheme of converting HTML files into Word files is mainly implemented by adopting some open source or commercial third party libraries, such as Aspose, openXML, etc., and the tools can convert simple HTML files into Word files, and retain original styles and formats.

However, these tools are not ideal for complex HTML document processing. Because the algorithms and the data structures adopted by the tools are relatively simple, each HTML label needs to be processed independently, the conversion speed is low, and because the difference between Word and HTML is large, especially because of the nested structure and the custom CSS style in the complex HTML file, the conversion error rate of the existing tools is high, and the flexibility is poor.

The drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those skilled in the art by reference to the specific embodiments.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.

First, the terms involved in the present application will be explained:

in the related art, for HTML files to be converted into Word files, there are two main methods, firstly, through a Word importing function, selecting "open" in a menu bar of Word, selecting "all files" or "web page" types in file types, then opening the HTML files to be converted, converting the HTML files into Word files, and retaining most of original formats and arrangement patterns, but if the HTML files contain some online pictures or links, problems such as link failure or picture failure can occur; secondly, through conversion tools, such as Aspose, openXML, the tools can process simple HTML files, but for special format HTML files, such as elements with various CSS attributes in the HTML or complex nested structures in the HTML, the conversion tools cannot recognize or accurately analyze, so that the conversion quality and the conversion speed have certain limitations.

Aiming at the technical problems, the embodiment of the application aims to provide a method, a system, equipment and a storage medium for converting an HTML file into a Word file.

The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 1 is a flowchart of a method for converting an HTML file into a Word file according to an embodiment of the present application. As shown in fig. 1, the method of the present embodiment includes:

s101: analyzing the HTML file to obtain a plurality of elements and element objects corresponding to the elements, wherein each element object comprises an attribute list, a sub-element list and a wide-high information list, and mapping relations are arranged among the attribute list, the sub-element list and the wide-high information list.

The execution main body of the embodiment of the application can be a server or an HTML file conversion system in the server, wherein the HTML file conversion system can be realized by software.

It is understood that elements refer to all codes in the HTML language from a start tag to an end tag, the content of an element being the content between the start tag and the end tag, most elements may possess properties and may be nested.

In this step, element parsing is performed on the HTML file. It should be noted that, due to the tolerant nature of HTML itself, HTML files cannot be parsed by a general top-down or bottom-up parser, but rather require algorithms for symbolizing and building a tree. And analyzing the HTML file according to the symbolization and tree building algorithm, so that element content, element attribute, nested structure information and width and height information can be obtained.

S102: traversing a sub-element list of the element object, calculating the height and width of each sub-element by adopting a preset recursion algorithm according to the mapping relation among the attribute list, the sub-element list and the width and height information list, and combining the height and width of the sub-element as the target height and width of the element.

In this embodiment, the nested structure in the HTML file is parsed to obtain a child element list of the element object, that is, the hierarchy of each element in the HTML file is divided according to the inclusion or peer relationship between the tags of the element, and the element including another element is a parent element of the included element, and conversely, the included element is a child element of the included element. Therefore, the method comprises the steps of firstly calculating the height and width of each sub-element, and then merging the height and width of the sub-elements according to the arrangement of the sub-elements to obtain the target height and width of the elements.

S103: and generating a Word file based on the element and the target height and width.

It will be appreciated that converting an HTML file to a Word file begins with the presentation of the content of the element in the document in a prescribed format.

In the step, each element is arranged and displayed according to the target width of the element, so that the content and arrangement in the generated Word file can be ensured to correspond to the original HTML file, and error leakage or document content dislocation caused by the error of the height and the width is avoided.

According to the method for converting the HTML file into the Word file, the HTML file is analyzed, a plurality of elements and element objects corresponding to the elements are obtained, each element object comprises an attribute list, a sub-element list and a wide-high information list, and mapping relations are arranged among the attribute list, the sub-element list and the wide-high information list; traversing a sub-element list of the element object, calculating the height and width of each sub-element by adopting a preset recursion algorithm according to the mapping relation among the attribute list, the sub-element list and the width and height information list, and combining the height and width of the sub-element as the target height and width of the element object; and generating a Word document based on the element and the target height and width. The method comprises the steps of analyzing the HTML file, expressing nested structure relations and CSS attributes in the HTML file by using a subelement list and an attribute list, calculating the height and width of each subelement, and combining the subelements to obtain the height and width of an element object, so that the error rate is low, and the method is suitable for converting the complicated HTML file.

The technical scheme of the method for converting the HTML file into the Word file is described in detail below.

In a possible implementation manner, the method for converting the HTML file into the Word file provided in the embodiment includes analyzing the HTML to obtain element tags, and then performing secondary analysis on the elements according to the element tags to obtain element objects corresponding to the elements.

Specifically, the parsing the HTML file to obtain a plurality of elements and element objects corresponding to the elements includes: analyzing the HTML file to obtain an element set, wherein the element set comprises a plurality of elements and element tags corresponding to the elements; and carrying out secondary analysis on the elements based on the element labels to obtain element objects corresponding to the elements.

It will be appreciated that HTML includes a series of element tags by which the document format on the network can be unified, allowing the distributed network resources to be connected as a logical whole, e.g., common element tags include < p > representing paragraph tags, < em > representing italic tags, < img > representing image tags, etc. Each element has its tag associated with it; and analyzing the HTML file to obtain the element labels of the elements and the element corresponding to the elements.

In this embodiment, the element is subjected to secondary parsing, that is, attribute information, sub-element information and bandwidth information of the element are obtained according to the element tag corresponding to the element. Illustratively, for an element whose element tag is < object >, the tag indicates that the element has an embedded object, so that sub-element information for the element can be obtained. From another aspect, the labels are inclusion or peer, and if the labels are inclusion, that is, one of the two elements is a parent element and one is a child element, for example, an html element defines the entire html document, and the element has a start label < html >, and an end label. And the element content of the html document is another element body, and the label of the element body is < body >. The body element defines the body part of an html document, and, relative to the body, html is the parent element of the body, and the body is the child element of html.

In the present embodiment, the CSS is a style for rendering the HTML element tag, for example, the < style > element is used in the HTML document header < head > region to contain the CSS.

In this embodiment, the element tag may also include high-width information, for example, the image tag < img > may include high values and wide values corresponding to the image element.

According to the method, the device and the system, the HTML is firstly analyzed to obtain the element tag, then the element is secondarily analyzed according to the element tag to obtain the element object corresponding to each element, the nested structure in the HTML file can be accurately analyzed, the information such as the attribute and the sub-element of each element in the HTML file is obtained, the applicability is high, and the problem of error analysis of the wide and high information caused by label nesting is effectively avoided.

In one possible implementation, considering a table element that may exist in the HTML file, each cell is a sub-element for the table element, and each cell has its attribute information and its width information; the element tag comprises a table element, and the table element comprises a plurality of cells.

Specifically, based on the element tag, performing secondary parsing on the element to obtain an element object corresponding to each element, including: taking the cell as a sub-element of the table element to generate a sub-element list; acquiring the cascading style sheet attribute of the cell and the cascading style sheet attribute of the table element, and generating an attribute list; and acquiring the height and width information of the cells and the height and width information of the table elements, and generating a height and width information list.

It will be appreciated that for a form element, its labels include < table > representing the form itself, < tr > representing the lateral form, < th > representing the header, and < td > for representing the text content of the form, it being noted that other attributes may be added to these labels to further modify the content.

In this step, each cell is taken as a subelement, i.e. a subelement list of the table cells can be generated from < tr >; and generating a corresponding attribute list according to the CSS attribute of each cell, and generating a corresponding height-width information list according to the height-width information of each cell.

According to the embodiment, aiming at the table elements in the HTML file, the nested structure of the table elements can be accurately analyzed, the information such as the attribute, the width and the like of each sub-element in the table elements is obtained, and the conversion error rate is reduced.

In a possible implementation manner, the method for converting an HTML file into a Word file according to the present embodiment performs a recursive calculation on the widths of sub-elements in a nested tag structure, and fig. 2 is a flowchart of a method for calculating the widths of all sub-elements by using a preset recursive algorithm according to the mapping relationship among the attribute list, the sub-element list, and the wide-high information list, as shown in fig. 2, and the calculating the widths of all sub-elements by using a preset recursive algorithm includes:

s201: and obtaining the cascading style sheet attribute corresponding to the sub-element according to the mapping relation between the attribute list and the sub-element list, and calculating the frame height and width of the sub-element according to the cascading style sheet attribute.

It can be understood that the label of the sub-element may include CSS attributes, such as a left margin, a right margin, and the like, and the frame height and width of the sub-element may be calculated according to the CSS attribute corresponding to the sub-element.

S202: and acquiring the standard height and width of the subelement according to the mapping relation between the subelement list and the width and height information list.

It will be appreciated that in HTML text, the size can be set using the height attribute and width attribute, only the "height" needs to be set for the element: length value "and" width: the length value is just the pattern; the unit of the length value can be px, cm, etc., and can also be "%" based on the percentage height of the block-level object containing the length value.

In this step, the label of the subelement may have content including its height=2cm and width=3cm, and these height and width information may be put into the height and width information list. Therefore, the standard height and width of the subelement can be obtained from the height and width information list according to the mapping relation between the subelement list and the width and height information list.

S203: and accumulating the frame height and width with the standard height and width to obtain the height and width of the subelement.

In this step, for each sub-element, the high value of its frame is accumulated with its standard high value, and the wide value of its frame is accumulated with its standard wide value, thereby obtaining the height and width of the sub-element.

In this embodiment, according to the mapping relationship among the attribute list, the subelement list and the width-height information list, a preset recursive algorithm is adopted to calculate the height-width of each subelement, so that the nested structure in the HTML markup language can be precisely matched, the conversion precision and efficiency are improved, the universality is strong, and more complex HTML documents can be processed.

In a possible implementation manner, the sub-element list includes each sub-element and a sub-element arrangement rule, and the method for converting the HTML file into the Word file according to the sub-element arrangement rule merges the widths of the sub-elements to obtain the target width of the element. Fig. 3 is a flowchart of a method for merging widths of sub-elements as target widths of the element objects according to the present embodiment, where, as shown in fig. 3, based on a rule of sub-element arrangement, merging widths of sub-elements as target widths of the element objects includes:

s301: and accumulating the high values of the sub-elements in each column based on the sub-element arrangement rule to obtain a high value set, and accumulating the wide values of the sub-elements in each row to obtain a wide value set.

It will be appreciated that the arrangement is sequential for the sub-elements of each element, and that the order or arrangement may be based on the labels of the sub-elements.

By way of example and not limitation, in a table element, the number of sub-elements in each row or column is not necessarily equal, nor is the height and width values equal, by a first number of sub-elements arranged laterally and by a second number of sub-elements arranged longitudinally. Thus, for each column of subelements, its high value is accumulated; for each row of subelements, its wide value is accumulated.

S302: and respectively selecting the maximum high value and the maximum wide value from the high value set and the wide value set as the expected high value and the expected wide value of the element object.

It will be appreciated that in order to be able to reveal all rows and all columns of sub-elements, it is necessary to use their maximum value as the expected value of the element, otherwise no suitable space is reserved for the element, and therefore the layout of the page will change when the file format is converted.

In this step, for a column of subelements, its largest high value is taken as the expected high value of the element; for a row of subelements, its largest width value is taken as the expected width value of the element.

S303: and judging whether the expected width value exceeds a preset limit value.

It will be appreciated that the height and width attributes have a hidden property in that one does not need to specify the actual size of the element, i.e., the two values may be larger or smaller than the actual size. The browser will automatically adjust the element to the size of this reserved space. For example, when the element is an image, a thumbnail thereof can be easily created for a large image using this method, and a very small image can be enlarged.

However, if the HTML file is converted into the Word file according to the original size, the width of the element cannot adapt to the standard of Word, but the original width and height of the element are not modified proportionally, so that the effect presented by the element may be distorted.

Therefore, in this embodiment, the size of the expected width of the element needs to be determined, and in view of the fact that the default format of Word is that the width value is smaller than the high value, the expected width value is used as a determination criterion, and in practical application, the expected width value and/or the expected high value may be used as a determination criterion according to needs, and the application is not limited to the determination of the expected width value and the high value.

S304: and if so, reducing the expected width value and the expected high value in an equal ratio until the expected width value is equal to a preset limit value, and taking the reduced expected width value and the reduced expected high value as the target height and width of the element object.

In this step, the expected width value exceeds a preset limit, and the expected width value needs to be scaled down at this time, and similarly, the expected high value needs to be scaled down in an equal proportion so that the element is not distorted.

It will be appreciated that scaling down the expected width and height values of an element is also true for scaling down the height and width of sub-elements in the element.

S305: and if not, taking the expected high value and the expected wide value as target height and width of the element object.

In this step, the expected width value does not exceed the preset limit value, which means that the expected width of the element meets the requirement of Word system, and no reduction processing is required for the expected width.

In this embodiment, for the element containing the sub-element, the height and width of the sub-element can be combined as the target height and width of the element object based on the sub-element arrangement rule, so that the problem of error analysis of the width and height information caused by label nesting is effectively avoided, multiple complex labels and CSS attributes are compatible, and the applicability is strong.

In a possible implementation manner, considering that part of the elements have no sub-elements, before traversing the sub-element list of the element object, the method further comprises: judging whether the subelement list is empty or not; if so, acquiring the frame height and the standard height of the element based on the mapping relation between the attribute list and the width and height information list, and accumulating the frame height and the standard height to acquire the target height of the element.

It will be appreciated that if an element has no subelements, its width needs only to be calculated from its own width and margin values.

In this step, the standard width of the element may be obtained from its content according to its tag, such as < img height= "value"/>, and < img width= "value"/>, respectively, representing the high value and the wide value of the image, that is, the standard width of the element. If the element has CSS attribute, calculating the outer edge distance, inner edge distance, frame width, distance from the element above, and the like of the element according to the content in the attribute, and obtaining the frame height and width of the element.

It can be understood that the step of accumulating the frame height and the standard height refers to accumulating the corresponding frame height and the corresponding standard height respectively according to the class pair of the CSS attribute, for example, accumulating the distance from the element above and the high value.

In this embodiment, for the element without sub-elements, the height and width of the element are calculated, the margin is calculated according to the CSS attribute, and the accumulated value of the height and width of the element and the margin is used as the target width, so that the typesetting of the document is more suitable, and the disorder of format is avoided.
