Marvelous. Thanks Jeni! Your first fix solves the problem; the second solution works also. I'm sure you're right the latter is more efficient, but my transformations so far are so short and simple that they take less than a second to execute. But I'll happily use your more efficient template anyway. Note to DaveP: you may want to update the FAQ to point to this corrected version of Jeni's general string replace template. ----- Original Message ----- From: "Jeni Tennison" <mail@xxxxxxxxxxxxxxxx> To: "Chris Nolte" <nolte@xxxxxxxxxxxxxxx> Cc: <xsl-list@xxxxxxxxxxxxxxxxxxxxxx> Sent: Thursday, June 07, 2001 10:22 AM Subject: Re: [xsl] general string replace problem > Hi Chris, > > > I'm still having problems using Jeni Tennison's general string > > replace template discussed in the FAQ: > > http://www.dpawson.co.uk/xsl/stringreplace.html#d44e34517 > > Oh dear.
