Subject: RE: [xsl] Outputing a node whose value appears only once From: Jonathan Marenus <jonathanmarenus@xxxxxxxxx> Date: Mon, 18 Jul 2005 22:06:07 -0700 (PDT) |
Ok, I kind of got your point thus far. In my example, I had two parents, 'a' and 'c'. How would I go about outputing what is in 'a' and not 'c' separately from outputing what is in 'c' but not 'a'. In other words, I want to run my XSL to account for both the unique values in 'a' as well as the unique values in 'c'. --- Michael Kay <mike@xxxxxxxxxxxx> wrote: > Read about Muenchian grouping at > http://www.jenitennison.com/xslt/grouping. > You can use the same idea to test whether a value is > unique within the file > (a member of a group of one) by defining the > grouping key > > <xsl:key name="gk" match="b|bb|bbb" use="."/> > > and testing a node > > <xsl:template match="b|bb|bbb"> > <xsl:if test="not(key('gk', .)[2])"> > The value is unique > </xsl:if> > </xsl:template> > > Michael Kay > http://www.saxonica.com/ > > > > -----Original Message----- > > From: Jonathan Marenus > [mailto:jonathanmarenus@xxxxxxxxx] > > Sent: 18 July 2005 23:35 > > To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > > Subject: [xsl] Outputing a node whose value > appears only once > > > > > > What I would like to do now is output a value that > > appears only once throughout the XML file.
