RE: [xsl] Count all instances of a named element in a tree

[Emmanuel Bégué <eb@xxxxxxxxxx>]

Hello,

If you don't want to use the '//' construct, you can use keys;
for example:

  <xsl:key name="nodes" match="countmein" use="'x'"/>
  <xsl:template match="/">
    <result countmein="{count(key('nodes','x'))}"/>
    </xsl:template>

Resulting document:
  <result countmein="8"/>

Regards,
EB
