Re: Using contains with more than one string - XSLT2.0

Beautiful!  Did not know about that one.  Many thanks, that appears to work
perfectly :)

If you're using XSLT 2, the function you want is matches() rather than
contains(). That allows you to use regular-expression syntax to express a
choice of strings to match. In this case you want

<xsl:for-each
select="//dsc//unittitle[matches(normalize-space(.),'Photo|Neg')]

or you can put the regular expression in your $target variable, so that simply
replacing "contains" with "matches" in your code below will work.

matches() is a lot more powerful than contains() because of its support for
regular expressions and case insensitivity (among other things).
