Answer 1

You can use alternation to avoid repetition:

<xsl:if test="matches($prose, concat('(^|\W)', $word, '($|\W)'),'i')">

Answer 2

If your XSLT 2.0 processor is Saxon 9 then you can use Java regular expression syntax (including \b) with the functions matches, tokenize and replace by starting the flag attribute with an exclamation mark:

<xsl:value-of select="matches('all foo is bar', '\bfoo\b', '!i')"/>

Michael Kay mentioned that option recently on the XSL mailing list.
