js访问xml之遍历节点树的代码
1，xml文件
book.xml
<bookstore>
<book category="COOKING">
<title lang="en">Everyday Italian</title>
<author>Giada De Laurentiis</author>
<year>2005</year>
<price>30.00</price>
</book>
<book category="CHILDREN">
<title lang="en">Harry Potter</title>
<author>J K. Rowling</author>
<year>2005</year>
<price>29.99</price>
</book>
<book category="WEB">
<title lang="en">XQuery Kick Start</title>
<author>James McGovern</author>
<author>Per Bothner</author>
<author>Kurt Cagle</author>
<author>James Linn</author>
<author>Vaidyanathan Nagarajan</author>
<year>2003</year>
<price>49.99</price>
</book>
<book category="WEB">
<title lang="en">Learning XML</title>
<author>Erik T. Ray</author>
<year>2003</year>
<price>39.95</price>
</book>
</bookstore>
2，js代码 books.jsp 用于节点遍历。
<html>
<head>
<script type="text/javascript" src="loadXML.js"></script> //在上面的一篇文章里面有
</head>
<body>
<script type="text/javascript">
xmlDoc=loadXMLDoc("book.xml");
// documentElement always represents the root node
x=xmlDoc.documentElement.childNodes;
for (i=0;i<x.length;i++)
{
document.write(x[i].nodeName);
document.write(": ");
document.write(x[i].childNodes[0].nodeValue);
document.write("<br />");
}
</script>
</body>
</html>
3，xml字符串 遍历节点树
<html>
<head>
<script type="text/javascript" src="loadXML.js"></script>
</head>
<body>
<script type="text/javascript">
text="<book>";
text=text+"<title>Everyday Italian</title>";
text=text+"<author>Giada De Laurentiis</author>";
text=text+"<year>2005</year>";
text=text+"</book>";
xmlDoc=loadXMLString(text);
// documentElement always represents the root node
x=xmlDoc.documentElement.childNodes;
for (i=0;i<x.length;i++)
{
document.write(x[i].nodeName);
document.write(": ");
document.write(x[i].childNodes[0].nodeValue);
document.write("<br />");
}
</script>
</body>
</html>
