"xml names cannot begin with character"
Contributor I
My process stops in certaing cases and i do not really find the answer what the reason is. Sometimes the message is that: Process failed: Tha name "µ
g" is not legal for JDOM/XML attributes: XML names cannot begin with the charater "µ". Do you know the reason??
my code is:
g" is not legal for JDOM/XML attributes: XML names cannot begin with the charater "µ". Do you know the reason??
my code is:

it seems to me there might be some encoding problems inside your web page processing. Sometimes webpages do not have the encoding they declare to have. So there might occur problems when trying to parse them as XML files (as the XPath expression would need to do).
Please try to check that...
