<html>
<head>
<title>
try to read the whole data from xml file whose structure is unknown
</title>
<script type="text/javascript" src="loadXMLDoc_vs.js" ></script>
</head>
<body>
<script type="text/javascript" language="javascript">
var grade=0;
function gradeWhitespace()
{
document.write("<br>");
for(var i=0;i<grade;i++)
{
document.write(" ");
}
}

function read(element)
{
if(element.childNodes[0].hasChildNodes)
{
gradeWhitespace();
document.write(element.nodeName);
grade++;
elementChild=element.firstChild;
while(elementChild !=null)
{
read(elementChild);
elementChild=elementChild.nextSibling;
}
grade--;

}

else
{
gradeWhitespace();
document.write(element.nodeName+":"+element.childNodes[0].nodeValue);

}

}

xmlDoc=loadXMLDoc("books.xml");
documentElement=xmlDoc.documentElement;
read(documentElement);
</script>
</body>
</html>
仅仅知道xml文件的文件名.
利用javascript读取xml的全部信息
算法有问题?
