Embodiment
The invention provides a kind of method and system that uses description document in webpage.The method combines description document and webpage HTML, and the method by description document is that the media (as video) in webpage or webpage provide service.In description document, comprise description event, description event can activate under certain conditions, and completes some predefined functions.Described function comprises the operation to element in webpage, and and far-end server mutual.Because the player framework of existing browser frames and embedding browser does not support to control function, therefore need independent program module to resolve description document, and complete the control to web page element.The video that another of this patent emphasis is placed upon embedding in webpage carries out alternately, for example, according to the process of video playback or user's operation, for user configures different advertisements, and plays in webpage.
Introduced in the present invention a kind of text mark language (MTML based on video, Media TextMarkup Language), this language and HTML are similar, different places is that this language is for the connection of media (as video) internal object and existing webpage HTML system, can complete like a cork redirect mutually between HTML and MTML, enrich level and the structure of existing network.
The present invention, for better and existing network structure well merges, has also proposed URL (unified resource location) solution based on description document, can, in the situation that retaining existing network/structure of web page, provide the service based on description document.
As shown in Figure 1, be a kind of description document workflow diagram of the embodiment of the present invention.According to HTTP (HTML (Hypertext Markup Language)) agreement, obtain the web page files of Web server.Present Web Site Interactive function majority is all that the control script by webpage self provides, these are controlled script and common are JavaScript, BVScript and Java etc., although webpage also can be by controlling some scripts or the program of script invoking web page outside, for example in the search homepage of google, just used such technology, but existing all webpage control technologys are not separated from realizing in essence control and the web page contents of webpage.As shown in Figure 1, the method that the embodiment of the present invention is used, is separated the content-control of webpage and content itself completely.First browser obtains Web file (html file), generates Web view, and by element object S1 in Web; When browser obtains Web or after obtaining Web, browser is fetched description document, and resolves description document S2; Browser comprises the assembly that can resolve description document, comprises description event in description document, then by browser inner assembly, judges the description event S3 that whether is activated; If the description event in description document is activated, carry out the description event S4 being activated in description document, the module of carrying out description document is also embedded in browser, and described module can be ActiveX control, java applet, browser intraware or plug-in unit etc.; If do not activate the description event in description document, the activation of the event to be described, such as continuation.Generally, in browser, responsible control of resolving description document is external module or the browser intrawares such as ActiveX control, Java.For the parsing of description document and the execution of the event of description, can adopt no program or control, also can in same program or control, by no module, process.
Fig. 2 is a kind of schematic diagram of controlling Web element by JavaScript and DOM of inventive embodiments.In Fig. 1, need the document element Web, could control the element in Web by description document like this, and existing method is DOM (text object model).DOM technology can form one tree structure by the element in webpage, and web page element is a node on this tree.The process of controlling Web element by JavaScript and DOM is as follows: (comprise and receive and resolve description document)
By DOM, resolving Web is an element-tree, can control the element 110 in Web by JavaScript.User side receives description document, and resolves 120 by description document parsing module, user side and user browser, and description document parsing module is inside or the external module of browser normally, for example, ActiveX, Java etc.The structure of description document is introduced in Fig. 5, Fig. 6, in description document, comprises description event, and these describe event is the structure that can carry out separately, and for example, video playback during to time A, is fetched advertisement B and plays in C position.Show as on stream, carry out the operational order of Web element according to time sequencing or operating position, according to time sequencing, for example, webpage, after playing for 5 seconds, is carried out an operation of scheme; According to operating position, for example, when user moves to mouse or click the individual position of scheme, carry out an operation of scheme.And operational order to Web comprises and adds element 140, deletes element 150, control element motion 160, fetches element and play 170.These controls to Web element, can utilize JavaScript etc. to control script, or utilize independent program or control in browser to complete, such as ActiveX etc.For the realization of DOM in Web, also can use JavaScript or by increasing inside or external module completes, for example following program listing in browser:
<html>
<head>
<title>JavaScript and DOM in this case</title>
<script language＝″JavaScript″>
function test(){
//These first two lines get the DOM tree for the current Web page，
//and then the<html>element for that DOM tree
var myDocument＝document；
var htmlElement＝myDocument.documentElement；
//What′s the name of the<html>element？″html″
alert(″The root element of the page is″+htmlElement.nodeName)；
//Look for the<head>element
var headElement＝htmlElement.getElementsByTagName(″head″)[0]；
if(headElement！＝null){
alert(″We found the head element，named″+headElement.nodeName)；
//Print out the title of the page
var titleElement＝headElement.getElementsByTagName(″title″)[0]；
if(titleElement！＝null){
//The text will be the first child node of the<title>element
var titleText＝titleElement.firstChild；
//We can get the text of the text node with nodeValue
alert(″The page title is′″+titleText.nodeValue+″′″)；
}
//After<head>is<body>
var bodyElement＝headElement.nextSibling；
while(bodyElement.nodeName.toLowerCase()！＝″body″){
bodyElement＝bodyElement.nextSibling；
}
//Found the<body>element...
//Remove all the top-level<img>elements in the body
if(bodyElement.hasChildNodes()){
for(i＝0；i＜bodyElement.childNodes.length；i++){
var currentNode＝bodyElement.childNodes[i]；
if(currentNode.nodeName.toLowerCase()＝＝″img″){
bodyElement.removeChild(currentNode)；
}}}}}

http: // .../C.htmlfile.
Fig. 6 is the network topology schematic diagram of the mixed structure of embodiment of the present invention description document (MTML) and existing HTML formation.In embodiments of the present invention, orientate MTML (Media Text MarkupLanguage) as description document title a kind of and media file binding, described media file comprises video file, picture file, animation file, audio files etc.In program, MTML is a kind of language that can be resolved, is generally class XML language, and its suffix can be set as required voluntarily, all belongs to the scope the present invention includes.But in Fig. 6, emphasis be take video file as example, introduction and HTML form the situation of mixed topology, and wherein HTML is a kind of among web page files, and suffix is generally html or htm, and web page files also comprises that asp, php, jsp, xml etc. are for the file of suffix.As Fig. 6,510 is web page files of an A.html by name, corresponding to the RUL on network, is
http: // .../A.html.In A.html, comprise A.mtml file 520 and B.html file 530, wherein A.mtml file is associated with the video file of an A.wmv by name, that is to say and found A.mtml just can find the position of A.wmv540, here this patent finds the method for corresponding media by description document, at webpage medium chain adaper, first find a description document, as A.mtml, and then find the corresponding media file of description document according to the narration in description document, but this process also can be conversely, first find media file, and then find the description document that media file is corresponding, only this mode need to increase the position of description document in media file.The associated method of above two kinds of description document media file corresponding with description document is all within this patent protection domain.Media file corresponding to description document and description document in use can be regarded an integral body as, but in manufacturing process, is to be but kept at respectively in two files.In Fig. 6, can find out, the URL of A.mtml file is mttp: // .../A.mtml, the mttp here (Media TextTransfer Protocol) in fact has the identical meaning with HTTP, it is all host-host protocol, because existing http supports text and hypertext transmission equally, therefore can use http agreement transmits mtml, and not necessarily need to make independent mttp agreement, transmits mtml.In A.mtml, the positional information that has comprised the file A.wmv540 associated with A.mtml, also be included in predefined description event while playing A.wmv, description document normally triggers by modes such as time or perception user operations, the function that description document is carried out can be to be linked to another URL, certainly this URL comprises HTML and MTML, and for example A.mtml comprises:
http://.../1.html
http://.../2.html
mttp://.../3.mtml
http://.../4.html
mttp://.../5.mtml
The media file that wherein 3.mtml is corresponding is 3.avi (521), and media file corresponding to 5.mtml is 5.rm (522).
For another, be included in the URL link http in A.html: // ... the web page files B.html (530) that/B.html is corresponding comprises:
http://.../6.html
http://.../7.html
mttp://.../8.mtml
So just formed the network topology on the right as shown in Figure 6, and this topology consists of mtml and html file.This topological structure is dissolved in Internet by the content in media file for the first time, the process of browsing can be such, first by browser, activate the URL that contains A.html and enter A.html, then can see two hyperlink, point to respectively A.mtml and B.html, be included in respectively mttp: // .../A.html and http: // ... in these two URL of/B.html.After building such network topology, it is very efficient with flexibly should using, for example, in A.wmv corresponding to A.mtml file, while being played to moment T, picture is a red benz sport car, trigger description event S, event S fetches 2.html, and 2.html is the webpage of introducing specially this red benz, wherein comprises the correlation parameters such as price.
Sum up, this is a kind of method that builds the mixed file topology of webpage and description document, it is characterized in that, comprises the following steps:
1) build following file structure: in webpage, comprise the network address of one or more description document and/or webpage, the network address that description document comprises one or more description document and/or webpage, and description document and to be described file corresponding one by one;
2) by ground floor webpage or description document, set out, traversal and ground floor webpage or description document have second layer webpage or the description document of link;
3) using current layer webpage or description document as 2) in ground floor webpage or description document, continue 2) in ergodic process;
4) repeating step 3).
