Re: Removing the extra elements through template match

change
    <xsl:template match='story'>
to
    <xsl:template match='/'>

so it matches the docuemnt root, then change
<xsl:value-of select="try_id"/>
to
<xsl:value-of select="aaxml/item/story/try_id"/>
so it works relative to the new current node, /.
