Re: dynamic node selection
Hi Tony, xsl:template name=createOptionList xsl:param name=parentNode select=string() / xsl:param name=childNode select=string() / xsl:variable name=targetNode select=concat(name($listNode),'/',$listItem) / xsl:for-each select=$targetNode ... do the processing /xsl:for-each Any advice, greatly appreciated. Adam, I'm not too sure what you're trying to do. Are you trying to create an element named with the value of $targetNode? Or are you trying to apply your templates to the nodes named in the value of $targetNode? If all you're trying to do is create a new named $targetNode, all you'd have to do is: xsl:element name=$targetNodefoo/xsl:element So, again, I'm not to sure what you're trying to accomplish.. perhaps an xslt list can help. Tony My apologies for the lack of clarity. I was trying to use the value I have calcualted for the $targetNode variable to select a node in my XML document. If I had an xml source like the following, I would like to be able to 'dynamically' select nodes for processing. root foo bar / bar / bar / /foo dog eatcat / eatcat / eatcat / /dog /root The xslt template to do the processing: xsl:template name=createOptionList xsl:param name=parentNode select=string() / xsl:param name=childNode select=string() / xsl:variable name=targetNode select=concat(name($listNode),'/',$listItem) / xsl:for-each select=$targetNode ... do the processing /xsl:for-each /xsl:template For example if parameters parentNode = foo and childNode = bar, then $targetNode would evaluate to the string foo/bar. I would want the 'for-each' statement to select all the bar nodes under the foo parent node. I think the only step I am missing is how to write a xpath node selection query that can take a string parameter as its argument. Thanks for your time Tony.

Re: dynamic node selection
Well, if you have your xpath in $targetnode, wouldn't it simply be: xsl:apply-templates select=$targetnode/? or xsl:for-each select=$targetnode xsl:apply-templates/ /xsl:for-each To go along with your code. I haven't done XSLT in a while, so I'm a little rusty. Hi Tony, The value of $targetNode is some arbitrary string value that (hopefully) looks like an xml node path. At design time I dont know all the possible values that the $targetNode string may have. I have tried to use the xsl:for-each select=$targetNode approach but it seems that the 'select' part doesnt like using a string parameter. I get the following error report from cocoon: Exception in creating Transform Handler More precisely: org.apache.cocoon.ProcessingException: Exception in creating Transform Handler: java.lang.NullPointerException If I could find a way to take the string value of $targetNode and actually select the corresponding nodes then I think the problem is solved.

--- Conal Tuohy [EMAIL PROTECTED] wrote: Adam there's no dynamic xpath expression evaluation in XSLT - you'll probably want to find some other way to identify the nodes you want to deal with since writing a generic xpath evaluator in XSLT is not going to be easy. It would be feasible though to parse some standard type of expressions rather than any arbitrary xpath. e.g. if you could ensure that all the xpaths were like: foo[1]/blah[2] - but this may not be feasible since you say you don't know the possible values that your xpath expression may have? Where do they come from? Hi Conal, I was getting the feeling that this was the case (i.e no dynamic xpath evaluation). I guess I have to go back and look at other ways to achieve a similar result. Thanks again to you and Tony for your help.

Re: dynamic node selection
Have you tried using name() function like: xsl:apply-templates select=/*[name()=$parentNode]/*[name()=$childNode]/ However, as far as I know name() function is there for emergency cases, rather than normal usage. If you know what the nodes might be, you might want to use several stylesheets and pick the right stylesheet dynamically. Hi Alex, In some cases I actually had the node corresponding to the parent and tried using the name() function to match the $childNode portion but it still didn't work. select=$parentNode/*[name()=$childNode] ($parentNode is an actual node, $childNode was the name of the desired target node below the parent). I was hoping to use this approach to help cleanup/refactor some verbose xslt code I have inheirited. Its not really a critical problem as the existing code is functionally correct, I was just trying to tidy it up a bit.

Re: Newbie In Peril
Thanks Nuno, Wow it looks much simpler than what I thought it would be. I have to finish the client side of the site first and then get on to the administator/maintenance side which is definitely going to require this authorisation mechanism. Thankyou. Thankyou. Thankyou! You have saved me a so much time and a lot of stress.

Re: Newbie In Peril
Hi Nuno, I tried to reply a few moments ago but yahoo mail was in an invalid state. I just hope you don't get 4-5 thankyou emails from me. Your solution makes it look so simple. I was thinking it was going to be very very hard and complicated to solve. I am only just begging to understand how powerful the sitemap is. I have to finish the client side of the application first before I can look at the administrator side of the web site. The administration side will definitely need to use the solution you have so generously provided. Thankyou. Thankyou. Thankyou! You have saved me so much time and stress. I hope that one day I will know enough about cocoon to also be able to give something back to new user's of cocoon.
