1 It is necessary to use the getElementsByTagName method to access the data in the XML document by name. 2. Analyze the application name to access the XML document. First use ActiveXObject to create a Microsoft parser instance, and then load the XML document into memory. Then use the getElementsByTagName() method to obtain references to the number element, name element and object element. The returned result is an array. Each element in the array corresponds to an element in the XML document, and the order is the same. Finally, obtain the value of the text contained in the corresponding element and concatenate the strings. 3. Note that JavaScript array subscripts start counting from 0. The FirstChild attribute indicates that you want to access the text contained in the name element, rather than accessing the name element itself; the data attribute gets the value of the node.

The implementation of RSS in XML is to organize content through a structured XML format. 1) RSS uses XML as the data exchange format, including elements such as channel information and project list. 2) When generating RSS files, content must be organized according to specifications and published to the server for subscription. 3) RSS files can be subscribed through a reader or plug-in to automatically update the content.

Advanced features of RSS include content namespaces, extension modules, and conditional subscriptions. 1) Content namespace extends RSS functionality, 2) Extended modules such as DublinCore or iTunes to add metadata, 3) Conditional subscription filters entries based on specific conditions. These functions are implemented by adding XML elements and attributes to improve information acquisition efficiency.
