I’m using XSLT to get data out of a feed. Currently I use this block of code, which simply picks the first item out of the feed. I changed it a bit so it applies to this sample XML.

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">
  <html>
  <body>
  <xsl:apply-templates/> 
  </body>
  </html>
</xsl:template>

<xsl:template match="/">
  <xsl:value-of select="catalog/book/author"/>
</xsl:template>

</xsl:stylesheet>

I want to sort the xml by price, and then pick the author associated with the highest priced book. I’ve tried all kind of things, but I can’t seem to figure it out.

The current output is “Gambardella, Matthew”, but I need it to be “Galos, Mike”.

    you can specify an <xsl:sort> inside apply-templates, like so:

    <xsl:template match="/">
    <html>
        <body>
            <xsl:apply-templates select="/catalog/book">
                <xsl:sort select="price" order="descending" data-type="number"/>
            </xsl:apply-templates>
        </body>
   </html>
</xsl:template>

    and then in your little ‘book’ template, use the position() to filter out only the first book node

    <xsl:template match="book">
    <xsl:if test="position() = 1">
        <xsl:value-of select="author"/>
        <br/>
        <xsl:value-of select="price"/>
    </xsl:if>
</xsl:template>
