[xsl] Finding Any Occurrance

["Bob Portnell" <simply.bobp@xxxxxxxxx>]

(Another baby question, but at least it's on-topic)

I have (successfully!) pulled some content from an outside file (and
hidden it in the variable $matcher). I now want to look through my
input file to see if that content is in any <title> child, anywhere,
so I know if it's worth carrying on processing for this content. But

<xsl:if test="//title = $matcher">

doesn't work. What have I overlooked?

(US correspondents, have a great holiday weekend!)
