Hmmm - iso-8859-1 should allow chars like "ä" "ü" "ö" ("ae", "ue", "oe") and
my XML is valid - but when I use tags like <über/> and call evaluate() then
I get an error:

XPath error in XPath.class_cvs.php:2680 While parsing the XPath query
"/Daten[1]/Visite[1]/über[1]/*" an empty and therefore invalid node-test has
been found.

When I change the first letter it is fine. It only happens when the special
char is at position 0 in the nodeName.

Help?
