(variants of this generate /*[local-name()='table'][2] or (for xpath 2) /*:table[2] if you want a version which shows the variable name but without namespace dependency) David ________________________________________________________________________ The Numerical Algorithms Group Ltd is a company registered in England and Wales with company number 1249803.
