首先建立一个index.html文件，放入如下代码

<html><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312" /><title>solution_description</title></head><body><h2>功能描述</h2><div id="showText"><textarea cols=120 rows=10 name="content" id="content" style="overflow: auto" readOnly="readOnly"></textarea><br/></div><script type="text/javascript">  window.onload= loadText;  function loadText()  {    var xdoc = new ActiveXObject("Microsoft.XMLDOM");xdoc.async = "false";xdoc.load('Solution_description.xml');nodes = xdoc.documentElement.childNodes;    var abc = document.getElementById("content");       //解析XML文件内容var len = nodes.length;for(var i = 0; i < len;i++){if(nodes[i].getAttribute('id') == "SW00w23")       abc.value = nodes[i].getAttribute('text');}  }    function msg1()  {     var cObj = document.getElementById("content");     cObj.removeAttribute("readOnly");  }    function msg2()  {  var cObj = document.getElementById("content");      cObj.setAttribute("readOnly",'true');  }</script><div id="buttons"><form><input type="button" value="修改" onClick="msg1()" /><input type="button" value="保存" onClick="msg2()" /></form></div></body></html>

在相同目录下建立一个Solution_description.xml文件

放入如下内容

<?xml version="1.0" encoding="gb2312"?><root>     <item id ="ST01" text = "Ashisgangshenmsyong"> </item> <item id ="SW00153" text = "ADSFASD"> </item> <item id ="SW00w23" text = "DSAF"> </item> <item id ="SW0103" text = "AFAF "> </item></root>

即可完成对XML的读及解析功能。
