Hi, I've got a problem which I think may be beyond the powers of XSLT 1, but maybe somebody can help me out. The simplified structure of the data is as follows: <articles> <article priority="3"> <title>second</title> </article> <article priority="9"> <title>first</title> </article> <article priority="1"> <title>last</title> </article> <article priority="3"> <title>third</title> </article> </articles> and I need to output it sorted on the "priority" attribute. Note that a) a higher value of priority is sorted to the top of the output (descending sort); b) some articles have the same priority, in which case they are output in source order; c) values for priority are not necessarily contiguous. There isn't a problem in the simple case: <xsl:template match="articles"> <xsl:apply-templates select="article"> <xsl:sort select="@priority" data-type="number" order="descending" /> </xsl:apply-templates> </xsl:template> <xsl:template match="article> <p><xsl:value-of select="title" /></p> </xsl:template> will give <p>first</p> <p>second</p> <p>third</p> <p>last</p> However, what I require is the following: <div> <p>first</p> <p>second</p> </div> <div> <p>third</p> <p>last</p> </div> The problem is that something like the following won't work: <xsl:template match="article> <div> <p><xsl:value-of select="title" /></p> <p><xsl:value-of select="following-sibling::article/title" /></p> </div> </xsl:template> as the following-sibling axis returns the nodes in original document order, not sorted order. Any suggestions as to how I can achieve the desired output would be appreciated. (Unfortunately, the obvious solution of converting the data so that the article elements are sorted before I get my hands on it won't work, as this is legacy data, and the idea is precisely to avoid having to do that... something to do with saving money on the back end.) Thanks in advance for any suggestions, Nick. -- Nick Fitzsimons http://www.nickfitz.co.uk/
