Re: [xsl] Convert text nodes to a single string

["Wendell Piez wapiez@xxxxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hey Rick,

Perhaps another way to accomplish your goal is simply a test on whether
such a text node child exists:

exists(child::text()[matches(.,'\S')])

returns true when a child text node has any non-whitespace content.

Cheers, Wendell
