Mozilla - minor problem

Hi,

I have written a js include that reads in an xml file and parses it. However I am having some minor problems!

I have loaded an XML file a method I have created, then once the document is loaded, I call a function that will parse the xml file:
xmlDoc.onload=parseXML(xmlDoc);

The first line of code in the XML parsing method is :

doc.getElementsByTagName('test').length;

However this line of code does not work unless I place an alert() popup just before this line ( the length is 0, if i put in the alert() the length is 10!!) It seems like a delay is required to give the xml document a chance to load, but I have tried putting in a while loop instead of an alert, but this does not work.

Thanks

Try:
setTimeout("doc.getElementsByTagName('test').length",2000);
