案例

Traverse node tree
遍历节点树
This example shows how to loop through all child nodes of <note>, and print the node name and the node value.
上述案例说明了对所有“<note>”子节点的循环操作方法,并打印了指定的节点名称和节点值。


Traversing the Node-tree
遍历节点树(Node-tree)

Often you will need to loop through elements in an XML document or string.
你可能经常需要对XML文档或字符串中的元素执行循环操作。

The example below loops through all child nodes of <note>, and prints the node name and the node value of each node:
下述案例说明了“<note>”子节点的循环方法,并打印了指定的节点名称和节点值:

<html>
<body>
<script type="text/javascript">
var text="<note>";
text=text+"<to>Tove</to>";
text=text+"<from>Jani</from>";
text=text+"<heading>Reminder</heading>";
text=text+"<body>Don't forget me this weekend!</body>";
text=text+"</note>";
// code for IE
if (window.ActiveXObject)
{
var doc=new ActiveXObject("Microsoft.XMLDOM");
doc.async="false";
doc.loadXML(text);
}
// code for Mozilla, Firefox, Opera, etc.
else
{
var parser=new DOMParser();
var doc=parser.parseFromString(text,"text/xml");
}
// documentElement always represents the root node
var x=doc.documentElement;
for (i=0;i<x.childNodes.length;i++)
{
document.write(x.childNodes[i].nodeName);
document.write("=");
document.write(x.childNodes[i].childNodes[0].nodeValue);
document.write("<br />");
}
</script>
</body>
</html>

Output:
输出结果:

to=Tove
from=Jani
heading=Reminder
body=Don't forget me this weekend!
