Hi Georg, Daniel Stucky solved
the problem and will present the solution. Best Andreas Von:
smila-user-bounces@xxxxxxxxxxx [mailto:smila-user-bounces@xxxxxxxxxxx] Im
Auftrag von August Georg Schmidt Hi Andreas, from my point of view
this looks like an malformed XML document that you enter into the pipelet. Could you give me a sample
for the information structure where this problem occurs? How is the XML
document parsed? Does it have something like a Unicode header in front of the
document (before <?xml version="1.0"
encoding="utf-8" ?> )? Kind Regards, Georg From: smila-user-bounces@xxxxxxxxxxx
[mailto:smila-user-bounces@xxxxxxxxxxx] On Behalf Of Andreas.Schultz@xxxxxxxxxxx Hello, I have problems using the XPathExtractorPipelet
within the addpipeline. Is anybody out there who has used this pipelet? Even the author.xml file of the unit-test for xmlprocessing
crashes! I got the following message: 2009-03-11 10:23:29,734 WARN
