This document describes how to load and read XML files in JavaScript. We will share this with you for your reference. The details are as follows:

When JS is used for loading and reading XML files during development, write down the file for reference. The following two steps are completed:

1. JS load XML files

The steps are generally (1) to create an xml dom object; (2) to set the loading method, asynchronous (recommended) or synchronous; (3) to provide the XML File URL and then call the load method; it is roughly as follows:

Var xmlFileName = "xxFile. xml "; var xmlDoc =''; if (window. activeXObject) {// IE var activeXNameList = new Array ("MSXML2.DOMDocument. 6.0 "," MSXML2.DOMDocument. 5.0 "," MSXML2.DOMDocument. 4.0 "," MSXML2.DOMDocument. 3.0 "," MSXML2.DOMDocument "," Microsoft. XMLDOM "," MSXML. DOMDocument "); for (var h = 0; h
2. JS nodes for reading XML files
After loading the XML file is to read the XML file node, you can use the DOM corresponding method, the ms ie other browsers read similar, for example:
For example, the XML file structure below:

  
         shenzhen    
         
    
     shenzhenNBA
          
    
     man
        
           shenzhen    
         
    
     xiaoming
          
    
     woman
        
       
         
    
     zhangsan
          
    
     man
        
     
  

// JS reads the area node in the XML file as follows: var nodeList = xmlDoc.doc umentElement. getElementsByTagName ("area"); // IEfor (var I = 0; I
  
   
There are also some methods to read nodes:
   


   
// MS IEnode. text; // read the node's text value node. childNodes [I]. text; // read the text node of the I-th [direct next level] subnode under the node. getAttribute ("attributeName"); // read the attribute name of the node as the attribute value of attributeName. // other methods can be found online.
   


   
// Non-MS IEnode. nodeValue; // read the node's text value node. childNodes [I]. nodeValue; // read the text node of the I-th [direct next level] subnode under the node. getAttribute ("attributeName"); // read the attribute name of the node as the attribute value of attributeName. // other methods can be found online.
