RE: Need to remove unusual character in source

xml clean control characters
XML 1.0 doesn't allow the control character x18. XML 1.1 does allow it,
provided it's represented as a numeric character reference.

XSLT can only process well-formed XML documents. If you have a document that
isn't well-formed XML, you need to clean it up using some non-XML-aware
process before you try putting it through an XML parser.

If you've agreed with your client, implicitly or explicitly, that it would
be beneficial to both parties to exchange data in XML, then I would point
out to the client that what they are sending you isn't XML and that this
destroys the point of the exercise.
