Thank you for your input, ~S.O.S~. It was going to be a hack, yes. It's an internal web-app that was written for IE6, and now they wish to have it work in IE7 and Firefox. The two parsers used here are xmlDoc=new ActiveXObject("Microsoft.XMLDOM"); and xmlDoc=new DOMParser(); . According to W3Schools, this is the way to handle parsing for IE/FF. So if these parsers handle things the same, then it's the responseText coming into them that is slightly different. I'm going with your suggestion of finding the root of the problem and trying to fix it there, instead of implementing a regex hack. I'll keep this thread updated with what I find out.

Thanks again,
