Re: Update Center fails to parse updates.xml generated by maven based application

I'd say download the actual XML in a browser, copy/paste it into NetBeans,
save as an XML file, and then right click and run Validate XML and see what
it says.

There's a good chance you're onto something with encoding issues.

In general, I'd say, don't try to do this in PHP.  Actually, don't try to
do anything in PHP.

FWIW, this might work better for you:
