Subject Re: How to use position() in Xpath query
Date Tue, 29 Jun 2010 08:26:48 GMT

Hello,

as I know, the position() function delivers only the order position in the
list of all childs of the parent node. So it is not 
usefull to limit the results of a query.

To limit the results in a query, you should use the "limit(int)" function
of the resulting query object.

Greetings
Michael
