There are three main approaches I can think of here.

(1) write an XSLT stylesheet that generates a new stylesheet in
which those XPath fragments (or template match patterns) are
in fact hard-coded...

(2) use the eval extension in an implementation that provides it

(3) interpret the XPath expression in XSLT.

E.g.
<xsl:template match="*">
  <xsl:param name="name" />

  <xsl:if test="localname() = $name">
     <xsl:message>got one!</xsl:message>
  </xsl:if>
  <xsl:apply-templates />
</xsl:template>

Well, this doesn't handle a/b, but you could use substring-after
to handle that, or, in XSLT 2, you could split the string on "/"
and then look for predicates, and you could do fancy things with count()
to sort into document rder & weed out duplicates.

But I'd favour approach (1) probably.
