I always thought of elements as mothers ;)

You'd probably be best off getting this by matching all those text
nodes that include the string ' Shakespeare', and then getting their
parent element.  You can get the parent with the XPath:

  ..

And then get its name with the name() function:

<xsl:variable name="query" select="' Shakespeare'" />

<xsl:template match="text()">
   <xsl:if test="contains(., $query)">
      <xsl:text>Query string contained in:</xsl:text>
      <xsl:value-of select="name(..)" />
   </xsl:if>
</xsl:template>

I hope that helps,

Jeni
