The software of the end.

Corresponding to the system of the present invention, the relationship between each unit and the module and the execution steps will be further explained in conjunction with the following method for non-intrusively driving an XML application on a web browser.

As shown in steps 301-302, when a user wants to download an XML-based data stream, the browser-side transceiver module 12 of the browser-side processing unit 1 transmits a corresponding HTTP request from the web browser.

As shown in steps 303-304, the server-side transceiver module 21 of the server-side processing unit 2 receives the HTTP request from the web browser; and the analysis module 22 analyzes the HTTP request to determine the basis. The way XML data streams are processed. If the analysis result of the analysis module 22 is: it is known that the web browser end meets a preset installation condition, then the processing of step 305 is continued; if the analysis result of the analysis module 22 is: the network is unknown. If the browser end meets the preset installation condition, proceed to step 306; if the analysis result of the analysis module 22 is: the web browser does not recognize or has other exceptions (Exception), then Proceed to the processing of step 308.

The preset installation condition is: the XML application is installed on the web browser, and the registration module 11 has registered one of the XML applications in the operating system of the web browser. Extension file name and A MIME contract type. On the network server side, the configuration setting module 24 will be configured in one of the MIME mapping classes of the network server to add the registered MIME in the operating system of the web browser. The contract type is the same as one of the set values.

As shown in step 305, when the web browser knows that the web browser end meets the preset installation condition, the data stream processing module 23 generates a standard XML-based data stream. Among them, the standard XML-based data stream refers to a data stream that conforms to the general well-known XML format.

As shown in step 306, when it is not known by the HTTP request whether the web browser end meets the preset installation condition, the data stream processing module 23 generates an XML-based data stream plus a PI announcement. The PI announcement refers to a URL of an Extensible Style Language (XSL) resource file, and the WebScript is to be executed in the XSL resource file.

As shown in step 307, after the processing of step 305 or step 306, the data stream processing module 23 packages the XML-based data stream.

As shown in steps 308-309, when the HTTP request is known to be unrecognizable by the HTTP request or other exception occurs, the data stream processing module 23 generates an HTML format data stream and wraps an HTML-based data stream. Data stream.

As shown in step 310, the XML-based data stream (standard XML-based data stream or XML-based XML data stream), and the HTML-based data stream can be collectively referred to as a Tag-based data stream, the server-side processing unit The server-side transceiver module 21 of 2 transmits the Tag-based data stream to the Web browser side.

As shown in steps 311-312, the browser-side transceiver module 12 of the browser-side processing unit 1 receives the Tag-based data stream from the network server, and then the determining module 13 analyzes the Tag-based data. flow. If the Tag-based data stream is an XML-based data stream, proceed to step 313; if the Tag-based data stream is an HTML-based data stream, proceed to step 316.

As shown in step 314, when the Tag-based data stream is an XML-based data stream generated in step 305 or step 306, and the web browser end meets the preset installation condition, the operating system prioritizes the data format. In the processing sequence, the application trigger module 14 drives the XML application in a non-intrusive manner. The non-intrusive method is: automatically driving the XML application through a Microsoft Object Linking and Embedding (OLE) technology according to the registered extension file name and MIME protocol type. At this time, the web browser application receives the XML-based data stream and executes the corresponding application function according to an XML message.

As shown in step 315, when the Tag-based data stream is the XML-based data stream generated in step 306, and the web browser end does not meet the preset installation condition, the priority order of the data format according to the operating system is processed. The redirection module 15 triggers the network in the XSL resource file according to the PI announcement. Travels segment.

As shown in step 316, the redirection module 15 redirects the web browser to the web address displaying a particular message. The specific message displayed by the web browser is the "no XML application installed" message; otherwise, the specific message displayed by the web browser is an "exception occurrence" message.

In summary, according to the system and method of the present invention, if an XML application is installed on the web browser, the XML application is automatically driven in a non-intrusive manner through OLE technology; if the web browser does not have XML installed The application redirects the web browser to the URL that displays the 'no XML application installed' message; unlike the conventional technology, it detects the web browser's work in a less secure and intrusive way. The configuration information of the system; therefore, it is indeed possible to achieve the object of the present invention.
