1、名称为myfile.xml的xml文件：
XmlDocument这样就可以通过XPATH来选择XML里的内容了:
<?xml version="1.0" encoding="utf-8" ?>
<myfile>
<title>tttt</title>
<author>ajie</author>
<email>ajie@aolhoo.com</email>
<date>20010115</date>
</myfile>
2、html代码：
<html>
<head>
<script language="JavaScript" for="window" event="onload">
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async="false";
xmlDoc.load("myfile.xml");
root = xmlDoc.documentElement;
//nodes = xmlDoc.documentElement.childNodes;
document.all("title").innerText = root.childNodes.item(0).text;
document.all("author").innerText = root.childNodes.item(1).text;
document.all("email").innerText = root.childNodes.item(2).text;
document.all("date").innerText = root.childNodes.item(3).text;
</script>
<title>在HTML中调用XML数据</title>
</head>
<body bgcolor="#FFFFFF">
<b>标题: </b>
<span id="title"> </span><br>
<b>作者: </b>
<span id="author"></span><br>
<b>信箱: </b>
<span id="email"></span><br>
<b>日期：</b>
<span id="date"></span><br>
</body>
</html>
这里XMLDoc相当于.NET里的,XmlDocument这样就可以通过XPATH来选择XML里的内容了:
items = xmldoc.selectNodes("invoices/invoice");
items = xmldoc.selectNodes("*/invoice");
items = xmldoc.documentElement.selectNodes("invoice");
function invoiceTotal(invoice)
{
invoice = invoice.nextNode()
items = invoice.selectNodes("items/item");
var sum = 0;
for (var item = items.nextNode(); item; item = items.nextNode())
{
var price = item.selectSingleNode("price").nodeTypedValue;
var qty = item.selectSingleNode("qty").nodeTypedValue;
sum += price * qty;
}
return sum;
}
