Loading Child Nodes Dynamically?

[cowsdonthack]

So, what I need to do is I need to display all the Options <OPT> of a product <PR> whenever it's selectedHow do you load all the Options <OPT> but only for each product <PR>?JS

oldTextAry = new Array();var xmlDoc;if (window.XMLHttpRequest)  {	xmlDoc=new window.XMLHttpRequest();	xmlDoc.open("GET","data.xml",false);	xmlDoc.send("");	xmlDoc=xmlDoc.responseXML;	}else if (ActiveXObject("Microsoft.XMLDOM"))  {	xmlDoc=new ActiveXObject("Microsoft.XMLDOM");	xmlDoc.async=false;  xmlDoc.load("data.xml");	}var x=xmlDoc.getElementsByTagName("PR");i=0;

XML

<PRODUCT>	<PR>		<TITLE>1E Series Cylinders - 1E2 Rim Cylinder</TITLE>		<IMG>http://www.asdf.com/images/cache/asdf.com-dc8ca9ef266a32a6fc42c80fbd39eb77.jpg</IMG>		<ENL>http://www.asdf.com/images/cache/asdf.com-b21e748612010de9b9c722fd474419d4.jpg</ENL>		<LINK> </LINK>		<INFO> </INFO>		<OPTION>			<OPT>1</OPT>			<OPT>2</OPT>			<OPT>3</OPT>			<OPT>4</OPT>			<OPT>5</OPT>		</OPTION>	</PR>	<PR>		<TITLE>1E6 Tapered Mortise Cylinder</TITLE>		<IMG>http://www.asdf.com/images/cache/asdf.com-9cb55aa0848d4c3fdd53b3600a6d8eb3.jpg</IMG>		<ENL>http://www.asdf.com/images/cache/asdf.com-d92d734b54b185fa6bd551673a3d63af.jpg</ENL>		<LINK> </LINK>		<INFO> </INFO>		<OPTION>			<OPT>3</OPT>			<OPT>4</OPT>			<OPT>5</OPT>			<OPT>8</OPT>			<OPT>3</OPT>		</OPTION>	</PR></PRODUCT>

The easiest (though probably not the most efficient way) is to loop over each PR element, check if it's the one you're looking for (e.g. by examining the contents of the TITLE element), and if it is, grab all of it's OPT elements (again with getElementsByTagName() I think), and then do whatever you want with each.

Thanks! But how do I do that? Like.. How do I getElementsByTagName() WITHIN a PR Element?

Doesn't

xmlDoc.getElementsByTagName("PR")[0].getElementsByTagName("OPT");

work (i.e. return an object, and not null)?
