Could you please give some words > on it? Hi Sun-fu, The result is a space-delimited string representation of the nodelist resulting from the sort operation. In the example above the result means that the "smallest node" has position 1, the next one has position 10, the next one has position 3,... etc. All positions have exactly the same number of digits (the same as string-length(count(theNodeSet))). So, in case the node-set to be sorted had only 9 elements, the above result would be: 1 3 9 6 ... This is by design, so that picking an individual position from this string should not be difficult -- the k-th position will be: substring(theResult, ($k - 1)*($posLength + 1) + 1, $posLength), where $posLength is defined as above: <xsl:variable name="posLength" select="string-length(count(theNodeSet))"/> I realise though, that even this may be difficult for subsequent processing of the results of the sort (e.g. one will have to use a recursive template in order to process the sorted sequence of nodes). I could create a nodeset of positions (or their respective nodes' generate-id()-s), so that it can be processed immediately with an xsl:for-each ? Do you think this would be useful? I would be happy to further assist you in using this template, do not hesitate to contact me. Cheers, Dimitre Novatchev. __________________________________________________ Do You Yahoo!?
