Howto generate a list xpath queries that are used within a template?

Hi,

for a school project i have to generate a html file containing metadata
about an xslt file. So i have a file xslt2html.xsl that has can do this. A
thing that has to be possible is to generate a list of all the templates and
for each template i have to generate more detailed information. t has to be
possible to generate a list of used xpath queries within a template. For the
moment, i use a template like this to do that:

<xsl:template name="generateUsedXpathQueries">
        <xsl:variable name="bla1" select="'joren'"/>
        <xsl:choose>
            <xsl:when test="@select">
                <li><xsl:value-of select="@select"/></li>
            </xsl:when>
            <xsl:when test="@test">
                <li><xsl:value-of select="@test"/></li>
            </xsl:when>
        </xsl:choose>
</xsl:template>

The problem with this solution is that i will miss xpath queries that arent
used in a select or test attribute. Does anyone know how i can generate a
list that doesnt leave any xpath queries out? is there a way to check if the
value of an attribute is a xpath-query or not?

This is my first post so i hope it does reach someone :)
