Hi, Malathi. Sorry that I didn't notice this problem earlier. The name of the Xalan-specific extension function is xalan:nodeset rather than xalan:node-set. I believe that's why you're getting the NoSuchMethodException. The following should work:
<xsl:for-each select="xalan:nodeset($grps)/Groups/Group"> Alternatively, for greatest portability, you might want to use the EXSLT common node-set extension function: <xsl:for-each select="common:node-set($grps)/Groups/Group" xmlns:common="http://exslt.org/common";> I hope that helps.

Brian/Henry – Any updates on this issue? We are stuck here as our Application is planning to upgrade our Selectica Engine to 9.1, which has Xalan 2.5. With Xalan 2.5, we were getting the error “Can not convert #RTREEFRAG to a NodeList!” – so we tried moving to Xalan 2.7.1 – hence then the below mentioned errors. Any help in this regard will be greatly appreciated. Thanks, Malathi Manivannan E-Configurator group Tellabs, Naperville IL.

Hi Henry - The grps variable is result tree fragment – with multiple “Group” nodes that I wan to traverse. Please see the attached xml –$grps refers to the <RightNav> tree fragment. This was working until we decided to upgrade Xalan (and also moved from JDK 1.4.2 to 1.5 ) I did try the change you suggested below, now I am getting the following error. org.apache.xml.utils.WrappedRuntimeException: java.lang.NoSuchMethodException: For extension function, could not find method org.apache.xalan.lib.Extensions.nodeSet([ExpressionContext,] #STRING). Checked both static and instance methods. Thanks, Malathi Manivannan E-Configurator group Tellabs, Naperville IL.

Hi, Malathi. What does the definition of the grps variable look like? The usual reason for this sort of error is that a result-tree fragment is being used in a context where a node set was expected. That's not permitted according to section 11.1 of XSLT 1.0,[1] so an operation like $grps/Groups/Group would not be permitted if the value of grps was a result-tree fragment. The node-set extension function allows you to tree a result-tree fragment as a node set, but in your example, you've made the argument to node-set be the result of the path expression, instead of applying it to the value of grps itself. Try changing this <xsl:for-each select="xalan:node-set($grps/Groups/Group)"> to this <xsl:for-each select="xalan:node-set($grps)/Groups/Group"> I hope that helps.

Hi Brian - I have tried both - the Xalan interpreter and XSLTC(with recomplied Stylesheet)..Still getting the same error.. ~Latha (a) Malathi ----- Original Message ---- From: Brian Minchau <[EMAIL PROTECTED]> To: Java Girl <[EMAIL PROTECTED]> Cc: xalan-j-users@xml.apache.org Sent: Monday, May 5, 2008 11:29:04 AM Subject: Xalan 2.7.1 class cast problem. Hi Latha. Looking at the class hierarchy, it does indeed look as though XNodeSet extends NodeSequence which extends XObject. XString extends XObject. So for 2.7.1 this casting is never right. Are you running the Xalan interpreter, or XSLTC? If XSLTC, did you recompile your stylesheet? - Brian Java Girl <[EMAIL PROTECTED]> Java Girl <[EMAIL PROTECTED]> 05/02/2008 02:49 PM To [EMAIL PROTECTED] cc Latha Mani <[EMAIL PROTECTED]> Subject Fw: XSLT 1.0 Brian - Would you be able to help me with this? I just upgraded from Xalan 2.4.1 to Xalan 2.7.1. Now I am getting " java.lang.ClassCastException: org.apache.xpath.objects.XString cannot be cast to org.apache.xpath.objects.XNodeSet " in the below line - I love the way the error points to the exact line number of the xslt :) I tried converting my xslt from <xsl:for-each select="$grps/Groups/Group"> to <xsl:for-each select="xalan:node-set($grps/Groups/Group)"> But I still get the same error.
