Ok, I believe I'm beginning to understand this stuff, enough to think that I've got a legitimate difficulty here: I've got an abstract concept of a rule mapping. This thing has multiple rule elements in it, each of which have multiple RHS. A rule mapping is an overall 'rule' of sorts, each rule element being a particular part of it. I want to find all the 'Context' elements that are being set by a rule mapping. To do so, I go to a RuleMapping element and from there find all the "Rule/RHS/Context[1]" Context elements. That's where there may be duplicates. Doing a [not(.=following::Context)] doesn't work since the 'following', if I'm correct, is at the rule mapping node that I happen to be sitting in and isn't referring to the particular nodes in the node set from my main path expression. I don't believe I can use the 'key' trick since the Context element is throughout my XML and I only want to do this duplicate analysis from within a particular rule mapping element. Here is some sample extract of my xml showing two rule mappings. For the first I should end up with three Context elements with which I can then display them. From the second, only one Context element. Really, I think this is trickier that it seems (or I'm being really stupid!). Thanks for any help! <RuleMapping id="626" name="from+bike+type+to+relevants+of+other+issues" issueid="131"> <RHS> <Context> <ObjectReference objectID="152" attributeGroupID="153" instanceID="0" attributeID="154"/> </Context> <Constant attributeid="154"> <DataValues><DataValue><Top><Boolean value="false"/></Top><Bottom><Boolean value="false"/></Bottom></DataValue></DataValues></Constant> </RHS> </Rule> <Rule id="628" name="from+bike+type+to+relevants+of+other+issues" issueid="131" situationid="304"> <RHS> <Context> <ObjectReference objectID="136" attributeGroupID="137" instanceID="0" attributeID="138"/> </Context> <Constant attributeid="138"> <DataValues><DataValue><Top><Boolean value="true"/></Top><Bottom><Boolean value="true"/></Bottom></DataValue></DataValues></Constant> </RHS> </Rule> <Rule id="629" name="from+bike+type+to+relevants+of+other+issues" issueid="131" situationid="306"> <RHS> <Context> <ObjectReference objectID="140" attributeGroupID="141" instanceID="0" attributeID="142"/> </Context> <Constant attributeid="142"> <DataValues><DataValue><Top><Boolean value="false"/></Top><Bottom><Boolean value="false"/></Bottom></DataValue></DataValues></Constant> </RHS> </Rule> </RuleMapping> <RuleMapping id="601" name="from+recreational+riding+and+road+conditions+to+bike+type" issueid="131"> <Properties> </Properties> <Rule id="602" name="from+recreational+riding+and+road+conditions+to+bike+type" issueid="131" situationid="235"> <RHS> <Context> <ObjectReference objectID="131" attributeGroupID="132" instanceID="0" attributeID="135"/> </Context> <Context> <ObjectReference objectID="136" attributeGroupID="137" instanceID="0" attributeID="138"/> </Context> </RHS> </Rule> <Rule id="603" name="from+recreational+riding+and+road+conditions+to+bike+type" issueid="131" situationid="255"> <RHS> <Context> <ObjectReference objectID="131" attributeGroupID="132" instanceID="0" attributeID="135"/> </Context> <Context> <ObjectReference objectID="136" attributeGroupID="137" instanceID="0" attributeID="138"/> </Context> </RHS> </Rule> <Rule id="604" name="from+recreational+riding+and+road+conditions+to+bike+type" issueid="131" situationid="225"> <RHS> <Context> <ObjectReference objectID="131" attributeGroupID="132" instanceID="0" attributeID="135"/> </Context> <Constant attributeid="135"> <DataValues><DataValue><Top><List value="1"/></Top><Bottom><List value="1"/></Bottom></DataValue></DataValues></Constant> </RHS> </Rule> </RuleMapping> Michal_Mart@xxxxxxxxxxx wrote: > > Hi Joel, > Will this work: > <xsl:template match="/"> > > <xsl:for-each > select="rule/rhs/value[1][not(.=following::rhs/value[1])]"> > > <xsl:value-of select="."/> > > </xsl:for-each> > > </xsl:template> > > HTH, > Michal > -- Joel Riedesel Jnana Technologies Corporation mailto:jriedese@xxxxxxxxx XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
