Deepak,

At 11:29 AM 11/1/2002, I wrote:

Or more simply, if a Y will never have more than one B, you can do

<xsl:template match="B">
  <B1>
    <xsl:apply-templates/>
  </B1>
</xsl:template>

This allows your rule (finding that you need a Y since you have a B='ABC') to be in one place, which is better; the down side is that if you have input like

<Y>
  <B>ABC</B>
  <B>LMN</B>
  <C>zzz</C>
<Y>

And your rules are only in the Y template, since "B[.='ABC'] or C[.='XYZ']" is true, all B and C elements will be processed.

Of course the simpler solution to this (doh!) is:

<xsl:template match="Y">
  <xsl:if test="B[.='ABC'] or C[.='XYZ']">
    <Y1>
      <xsl:apply-templates select="B[.='ABC'] | C[.='XYZ']"/>
    </Y1>
  </xsl:if>
</xsl:template>

or the analogous logic. Then you need no logic in the B template.

Incidentally, this can be further compressed (if you like) as:

<xsl:template match="Y[B[.='ABC'] or C[.='XYZ']]">
  <Y1>
    <xsl:apply-templates select="B[.='ABC'] | C[.='XYZ']"/>
  </Y1>
</xsl:template>

<xsl:template match="Y"/> <!-- this suppresses a Y unless it matches the other template -->

Cheers,
Wendell
