Re: [xsl] Matching for strings...

Bob,

Was it someone else who asked something very closely analogous to 
this just a week or two ago?

In any case,

At 11:35 AM 9/6/2006, you wrote:

Right. When they try this sort of thing people generally want

<xsl:if test="//tv:program[matches(normalize-space(),$target]">

which tests true if such a node exists.

An optimized processor, I assume, will return true as soon as it 
finds one such node. A naive one will examine all of them before 
returning true.

Cheers,
Wendell
