Hi Andreas,
the XPath predicate is particularly intriguing, as the specified condition
'number(.)=number(.)' will always be true (all nodes for which it is true
that their content, when converted to a number, equals their own content
converted to a number)
This is not strictly true,
Michael Kay's Programmer's reference, second edition, page 90 says:
The equals operator «=» returns false if either or both oprands are NaN...
Therefore this is a test to see whether the node will convert to a number.
Regards,
Ragulf Pickaxe :)
