Re: [saxon] template match dependent on parent

No. It just moves the test from the match pattern to inside the
template rule and it's more verbose.

Giving it further thought I think this is a case for a pull processing.

<xsl:template match="onTheParentOFA">
  <xsl:if test="@attr eq 'datasource1'">
     <xsl:for-each select="a">
        etc
     </xsl:for-each>
  </xsl:if>
    <xsl:if test="@attr eq 'datasource2'">
     <xsl:for-each select="a">
        etc
     </xsl:for-each>
  </xsl:if>
</xsl:template>

and the test for the datasource only gets done once.

Apologies I just realised I sent this to the wrong mailing list.
Correcting that now.
