RE: [xsl] Aberrant Alphabetizing.

Hi Wendy,

Unfortunately you have also fallen into the for-each trap... using <xsl:for-each select="."> as the first child of a matching template will always select just one node - the element that it is being matched against.

What I think you should be doing is sorting the <book> child nodes of whatever parent they have by title, something like:
 
<xsl:template match="insert-parent-of-book-here">
  <xsl:apply-templates select="book">
    <xsl:sort select="title"/>
  </xsl:apply-templates>
</xsl:template>

Think of it as building a list of nodes to process using <xsl:apply-templates select="..."/>, and then sorting them using <xsl:sort/>

cheers
andrew
