XSLT 2 is preferred and I hope makes this easier.Given a document similar to\[code\]<doc xmlns:bob="bob.com"> <element bob:name="fred" bob
ccupation="Dr">Stuff</element> <element bob:name="Bill" bobccupation="Dr" bob:birthMonth="Jan"/> <element>Kill Me</element> <element bob:name="fred" bobccupation="Dr">different Stuff</element></doc>\[/code\]I would like to have all of the unique elements based on all the attributes in bob namespace. This is a representative sample but I will have much deeper nesting so all I want it to traverse the tree for \[code\]*[@bob:*] and get the unique set of those.\[/code\]The hoped for output would look like\[code\]<doc xmlns:bob="bob.com"> <element bob:name="fred" bobccupation="Dr">Stuff</element> <element bob:name="Bill" bobccupation="Dr" bob:birthMonth="Jan"/></doc>\[/code\]where one element was removed for not having any @bob:* attributes and the other was removed for being a duplicate of the first based solely on the attributes.I was trying to use a key but didn't seem to be doing it right\[code\]<xsl:key name="BobAttributes" match="//*" use="./@bob:*" />\[/code\]I also tried creating a function that concatenated all the @bob attributes but that also didn't seem to do what I hoped.\[code\]<xsl:key name="BobAttributes" match="//*" use="functx:AllBobConcat(.)" /> <xsl:function name="functx:AllBobConcat" as="xs:string*" xmlns:functx="http://www.functx.com" > <xsl
aram name="nodes" as="node()*"/> <xsl:for-each select="$nodes/@bob:*"> <xsl:value-of select="local-name(.)"/> <xsl:value-of select="."/> </xsl:for-each></xsl:function>\[/code\]In both cases I was using "simple" XSL to filter out the unique ones maybe I blew it here?Variables added here to try and debug.\[code\] <xsl:template match="*[@ism:*]" priority="100"> <xsl:variable name="concat"> <xsl:value-of select="functx:AllBobConcat(.)"/> </xsl:variable> <xsl:variable name="myID"> <xsl:value-of select="generate-id() "/> </xsl:variable> <xsl:variable name="Keylookup"> <xsl:value-of select="key('BobAttributes', $concat)"/> </xsl:variable> <xsl:value-of select="concat($concat, $Keylookup, $myID)"/> <xsl:if test="generate-id() = generate-id(key('BobAttributes', $concat)[1])"> <xsl:apply-templates select="." mode="copy"/> </xsl:if> </xsl:template> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="@*|node()" mode="copy"> <xsl:copy> <xsl:apply-templates select="@*|node()" /> </xsl:copy> </xsl:template>\[/code\]Looking forward to hearing what simple thing I overlooked or completely different cool approach I should have taken.
