Example:
<list>
<item>string1</item>
<item>string2</item>
<item>string2</item>
<item>string3</item>
</list>
I want to get the following list, omitting the second node
with the value "String2". string1 string2 string3
If you find grouping with XSLT 1.0 a bit heavy going, download Saxon and
use XSLT 2.0's grouping functionality:
<xsl:for-each-group select="list/item" group-by=".">
...
</xsl:for-each-group>
Easy, isn't it? You may need to use Xpath 2.0's distinct-values()
function on the current-group(), depending on what you want to do inside
the loop.
