XPath error in XPath.class.php:1117 The //error[@id=3D'-100'] does not =
evaluate to a single node in this document.

[Nigel S. <nig...@us...>]

Please send us your error.xml file.  It sounds likely that there is more
than one error node with an @id attribute of -100.  Without seeing the xml
file, then we can only guess...

Please also tell us what version of the class you are using.

Thanks,

Nigel
