In case preserving of whitespace-only nodes has not been turned off and the xml source has "a single tag with all attributs/namespace definitions" on a single line, then the following gives the exact line number: count(preceding::text()[contains(., '
')]) + 1 ===== Cheers, Dimitre Novatchev. http://fxsl.sourceforge.net/ -- the home of FXSL "S Woodside" <sbwoodside@xxxxxxxxx> wrote in message news:FD40E2C0-2DC9-11D7-86C5-000393414368@xxxxxxxxxxxx > The FAQ is pretty thin on debugging tips, so I thought I'd share this > that I came up with. the gurus on the list can probably improve it ;-) > > I wanted to include a line number in the output that would take me to > the line in the source XML that is being processed.
