XML DOM nodeValue 属性
Attr 对象定义和用法
nodeValue 属性设置或返回节点的值，根据其类型。
语法
attrObject.nodeValue
实例
下面的代码片段使用 loadXMLDoc() 把 "books.xml" 载入 xmlDoc 中，并显示 category 属性的节点名称、节点值和节点类型：
实例
xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.getElementsByTagName('book');
for(i=0;i<x.length;i++)
{
document.write(x.item(i).attributes[0].nodeName);
document.write(" = ");
document.write(x.item(i).attributes[0].nodeValue);
document.write(" (nodetype: ");
document.write(x.item(i).attributes[0].nodeType + ")");
document.write("
");
}
x=xmlDoc.getElementsByTagName('book');
for(i=0;i<x.length;i++)
{
document.write(x.item(i).attributes[0].nodeName);
document.write(" = ");
document.write(x.item(i).attributes[0].nodeValue);
document.write(" (nodetype: ");
document.write(x.item(i).attributes[0].nodeType + ")");
document.write("
");
}
输出：
category = COOKING (nodetype: 2)
category = CHILDREN (nodetype: 2)
category = WEB (nodetype: 2)
category = WEB (nodetype: 2)
category = CHILDREN (nodetype: 2)
category = WEB (nodetype: 2)
category = WEB (nodetype: 2)
