RE: [xsl] The right way to count from inside a match template

["Michael Kay" <mike@xxxxxxxxxxxx>]

The simplest way is just <xsl:number/> with no attributes.

In most cases you can also use position() - but the value of position()
depends on how the template was invoked. If it was invoked by

<xsl:template match="root">
  <xsl:apply-templates select="a"/>
</xsl:template>

then position() will give you the answer you want; but if it was

<xsl:template match="b">
 <xsl:apply-templates select=".."/>
</xsl:template>

then it won't.

count(preceding-sibling::a)+1 should also work.
