Javascript解析xml

从文件解析：

<html>
<body>
<script type="text/javascript">
try //Internet Explorer
  {
  xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
  }
catch(e)
  {
  try //Firefox, Mozilla, Opera, etc.
    {
    xmlDoc=document.implementation.createDocument("","",null);
    }
  catch(e) {alert(e.message)}
  }
try 
  {
  xmlDoc.async=false;
  xmlDoc.load("books.xml");
  document.write("xmlDoc is loaded, ready for use");
  }
catch(e) {alert(e.message)}
</script>
</body>
</html>

从字符串中解析：

<html>
<body>
<script type="text/javascript">
text="<bookstore>"
text=text+"<book>";
text=text+"<title>Harry Potter</title>";
text=text+"<author>J K. Rowling</author>";
text=text+"<year>2005</year>";
text=text+"</book>";
text=text+"</bookstore>";

try //Internet Explorer
  {
  xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
  xmlDoc.async="false";
  xmlDoc.loadXML(text);
  }
catch(e)
  {
  try //Firefox, Mozilla, Opera, etc.
    {
    parser=new DOMParser();
    xmlDoc=parser.parseFromString(text,"text/xml");
    }
  catch(e) {alert(e.message)}
  }
document.write("xmlDoc is loaded, ready for use");
</script>
</body>
</html>

接下来就类似DOM操作xml文档了
