I need to parse a element from a XML file:
<a>
<b>45</b>
<c>67</c>
</a>
<a>
<b>98</b>
<c>89</c>
</a>
So I try to read and put in a html element the first value of b with the next code:
and I get a undefined message.Where is the problem?

document.getElementById("apDiv3").innerHTML=xmlDoc.getElementsByTagName("b")[0].data;
or
document.getElementById("apDiv3").innerHTML=xmlDoc.getElementsByTagName("b")[0].value;
and I get a undefined message.Where is the problem?

Your XML file is not proper, there can be only one root element. Also since you have not posted the entire code, I would give you a small example on how to go about things:
In case of any queries, do ask again.
// Javascript file
<html>
<head>
<title>XML DOM</title>
<script type="text/javascript">
var xmlDoc;
function parse()
{
alert('in parse');
if(window.ActiveXObject)
{
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = false;
xmlDoc.load("notes.xml");
display();
}
else if(document.implementation.createDocument)
{
xmlDoc = document.implementation.createDocument("", "", null);
xmlDoc.load("notes.xml");
xmlDoc.onload = display;
}
else
{
alert("Browser doesn't support XML DOM manipulation");
}
alert('out parse');
}
function display()
{
alert('In display');
document.getElementById('b1').innerHTML = xmlDoc.getElementsByTagName("b")[0].childNodes[0].nodeValue;
document.getElementById('c1').innerHTML = xmlDoc.getElementsByTagName("c")[0].childNodes[0].nodeValue;
document.getElementById('b2').innerHTML = xmlDoc.getElementsByTagName("b")[1].childNodes[0].nodeValue;
document.getElementById('c2').innerHTML = xmlDoc.getElementsByTagName("c")[1].childNodes[0].nodeValue;
}
</script>
</head>
<body onload="parse();">
<p>b1: <span id="b1"></span></p>
<p>c1: <span id="c1"></span></p>
<p>b2: <span id="b2"></span></p>
<p>c2: <span id="c2"></span></p>
</body>
</html>// XML Document
<root>
<a>
<b>100</b>
<c>200</c>
</a>
<a>
<b>300</b>
<c>400</c>
</a>
</root>In case of any queries, do ask again.

I am back with an other question.
I want to put the xml elements values using a for cycle in input fields
I want that input_element to be a variable that depend on i, and in function of i to represent a real html input element value.
Can you give me a solution?
