You can select the first NatureInterestCd = LIEN, using the predicate AdditionalInterestInfo[NatureInterestCD='LIEN'][1] In XPath 2.0 you can then exclude this from your result set by using the "except" operator, and similarly for the other exclusions. It's harder to do "A except B" in XPath 1.0: EXSLT offers a set:difference() extension function, or you can use logic based on generate-id() or on the formula A[count(.|B) != count(B)] Alternatively, you can use a predicate such as AdditionalInterestInfo[not(NatureInterestCD='LIEN' and not(preceding-sibling::*[NatureInterestCD='LIEN']))] Michael Kay > -----Original Message----- > From: Dale Earnest [mailto:dale.earnest@xxxxxxxxxxxxxxxxxxxxxxx] > Sent: 11 August 2004 01:01 > To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > Subject: [xsl] XSL Problem > > I've run into a difficult xslt problem and I was hoping > someone may have some insight. > > I have an XML structure that looks like this (the '...'s > represent nodes that aren't directly relevant to the question > and are omitted): > > <PersAutoInsurance> > <PersVeh> > ... > <AdditionalInterest> > <AdditionalInterestInfo> > <NatureInterestCd>ADDIN</NatureInterestCd> > </AdditionalInterestInfo> > </AdditionalInterest> > <AdditionalInterest> > ... > <AdditionalInterestInfo> > <NatureInterestCd>LIEN</NatureInterestCd> > </AdditionalInterestInfo> > </AdditionalInterest> > <AdditionalInterest> > ... > <AdditionalInterestInfo> > <NatureInterestCd>LIEN</NatureInterestCd> > </AdditionalInterestInfo> > </AdditionalInterest> > </PersVeh> > <PersVeh> > <AdditionalInterest> > ... > <AdditionalInterestInfo> > <NatureInterestCd>ADDIN</NatureInterestCd> > </AdditionalInterestInfo> > </AdditionalInterest> > <AdditionalInterest> > ... > <AdditionalInterestInfo> > <NatureInterestCd>LIEN</NatureInterestCd> > </AdditionalInterestInfo> > </AdditionalInterest> > <AdditionalInterest> > ... > <AdditionalInterestInfo> > <NatureInterestCd>AIL</NatureInterestCd> > </AdditionalInterestInfo> > </AdditionalInterest> > </PersVeh> > </PersAutoInsurance> > > What I'm trying to do is select NatureInterestCd's based on > the following criteria: > 1) I cannot accept the first NatureInterestCd = LIEN for each > vehicle (but may accept any subsequent for processing) > 2) I cannot accept the first NatureInterestCd = AIL for each > vehicle (but may accept any subsequent for processing) > 2) I can accept any other node > > I attempted to use this type of statement to get the nodes > and loop over them: > <xsl:for-each > select="PersAutoInsurance/PersVeh/AdditionalInterest/Additiona > lInterestInfo[not(NatureInterestCd = 'LIEN') and > not(NatureInterestCd = 'AIL')]"> > > But that eliminates all nodes, not simply the first.
