I have looked at the FAQ(s) and not been able to get the
sort/no duplicate thing to work. Below is an example
of an XML and XSL file. All I want to do is print out
the data so I have a list of cities with no duplicates.
With the example XML below that would be:
'boston new york'
Can someone revise my stylesheet so it will work.
I am using php with Sablotron.
*** sort.xml
<?xml version="1.0" ?>
<contents>
<entry>
<city>boston</city><record>one</record>
</entry>
<entry>
<city>boston</city><record>two</record>
</entry>
<entry>
<city>new york</city><record>one</record>
</entry>
</contents>
*** sort.xsl
<xsl:template match="/"> <!-- At top of page -->
<xsl:for-each select="contents/entry/city[not(.=preceding-sibling::contents/entry/city)]">
<xsl:sort/>
<xsl:value-of select="."/>
</xsl:for-each>
</xsl:template> <!-- At bottom of page -->
