Hi Maia,

You want to get the attr whose name is "trap type". You can do this
with a predicate, as follows:

  attrList/attr[name = 'trap type']

>From that attr element, you want to get the data element, which you
can do with:

  attrList/attr[name = 'trap type']/data

So your sort should look like:

  <xsl:apply-templates select="Event">
    <xsl:sort select="attrList/attr[name = 'trap type']/data" />
  </xsl:apply-templates>

Cheers,

Jeni
