[wpkg-users] How to identify malformed XML

[Jason Taylor]

Sometimes, after editing a package definition, wpkg will start complaining about malformed XML and no root elements. Could anyone give me some pointers on how to identify where the problem is? In my editor (ST2) it doesn't show any inconsistent highlighting or anything that screams "invalid XML!"

The last couple times this happened, I just re-wrote the file from scratch and the problem went away. I would rather find out what I'm doing wrong than re-writing it every time this happens.

These are the debug messages I'm getting:
---
Error parsing xml '//domain/it/software/wpkg/packages/WorkshareProfessional.xml': The stylesheet does not contain a document element.  The stylesheet may be empty, or it may not be a well-formed XML document.                                                                                       
No root element found in '//domain/it/software/wpkg/packages/WorkshareProfessional.xml'.

And here is the package definition in full:
---

			</condition>
		</upgrade>

	</package>

This package definition broke after I added the two WORKSHAREOPTIONS variable assignments, and the regedit upgrade command. I don't see anything wrong with those items, though. I don't think it's a file encoding problem as this, and all other, files are UTF-8.

Any advice on finding out what's wrong here would be greatly appreciated!
