error checking XML file??

[mquach]

I've got an XML file that I've loaded into Flash using the code:

objXML = new XML();
objXML.ignoreWhite = true;
objXML.onLoad = parseXMLData;
objXML.load("data.xml");

The parseXMLData code:

function parseXMLData(success) {
if (success) {
//goes through each node and builds an array of objects for use
}
}

Everything works fine when the XML is as it is suppose to be (well formed).

How do I check if the XML file is well formed before I use it? I want to trap bad files from coming in so that I can show an error message detailing what's wrong with the XML file.

Please help.

Thanks.

How bad is bad? valid XML but not what you are expecting or are you talking about when someone saves a picture and names it .xml. Flash will handle the latter, you will have to code for the former.

Bad meaning missing brackets in the tags, missing end tags, etc. How do I code to check this?

Thanks!

Typically flash won't parse the code, success variable in your parseXMLData function will be false.

Flash is lenient with some things in XML that I know Java parsers will stop on (multiple root tags being one of them that flash accepts), but will stop for really badly formed xml.
