Importing XML data using JS/DOM. IE5/Gecko 1.0-compliant.

[Skyzyx]

If you have an XML file named "names.xml" that looks like this,

<?xml version="1.0"?>
<DOC>
	<DATA>Bobby</DATA>
	<DATA>Fredo</DATA>
	<DATA>Miguel</DATA>
</DOC>

You'll want your script to do something like this:

/*************************************
This function loads the file when run.
*************************************/
function importXML(zFileName)
{
	var xmlDoc;
	var moz = (typeof document.implementation != 'undefined') && (typeof document.implementation.createDocument != 'undefined');
	var ie = (typeof window.ActiveXObject != 'undefined');

	if (moz)
	{
		xmlDoc = document.implementation.createDocument("", "", null)
		xmlDoc.onload = readXML;
	}

	else if (ie)
	{
		xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
		xmlDoc.onreadystatechange = function()
		{
			if (xmlDoc.readyState == 4) setTimeout(readXML,0);
		}
	}

	xmlDoc.load(zFileName);
}


/*************************************
This is the function that is run when importXML()
is called...
*************************************/
function readXML()
{
	var xmlFile=xmlDoc.getElementsByTagName("DOC"); // There is only one DOC tag, so this is a variable instead of an array.
	var xmlFileData=xmlFile.getElementsByTagName("DATA"); // There is more than one DATA tag, so this becomes an array.  The first DATA tag (value is Bobby) can be accessed as xmlData[0], the next xmlData[1], and so on.

	for (x=0; x < xmlFileData.length; x++) // Since this is an array...
	{
		document.write(xmlFileData[x] + '<br />');
	}
}


/*************************************
Actually import the document.
*************************************/
var loc=location.href;
if (loc.indexOf('.htm?') != -1)
{
	var impurl=loc.split('?');
	importXML(impurl[1]);
}
else alert('You need to specify an XML document to load.');

With this, you can use the same HTML page to load different XML files one at a time. For example, you would pull up a new page by going to "http://www.domain.com/filename.htm?names.xml". After the filename.htm, you would add a ? followed by the name of the XML file, not quotated.

Granted, you can do much more with the readXML() function than this, but this is just something that you can look at to figure out where you can go from here.
