Not in a procedural sense (incrementing a loop counter, for instance), but there's other ways you could determine this. Output the count of nodes matching your template rule: <xsl:value-of select="count(/document/book/pages)"/> Or output the position of the node being processed by a matching template: <current-node><xsl:value-of select="position()"/></current-node> Note that this will be the position of the *output* nodes--after any sorting is done--not the order of nodes in the source document. But it will still tell you how many times the template was invoked. > 3. Is there an easy to implement a counter or a boolean in > xsl? If yes then > how? Implementing either one would be fine. Not for a loop counter, but you're also looking at your problem from a procedural rather than a functional perspective. When you build a result tree from your input, there should be no need for a loop counter--you simply provide templates that match the nodes you want to process, and output them in the format you want. As far as booleans go, they exist in XSLT--but they're not needed to control loops or for other procedural logic. Your processing can be controlled entirely by iteration using xsl:for-each or by rules-based templates. cheers, b. | brian martinez brian.martinez@xxxxxxxx | | senior gui programmer 303.708.7248 | | trip network, inc. fax 303.790.9350 | | 6436 s. racine cir. englewood, co 80111 | | http://www.cheaptickets.com/ http://www.trip.com/ | XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
