Ram, rather than replying to individual posters please reply to the list
with follow-up questions, and try to specify your original question as
precisely as possible.

If you don't want attributes then the problem is a little more difficult.
You can't make use of <xsl:copy-of> so you'll have to use recursion.  You
don't want to make use of the built-in template for elements because that
only copies the text value of the element.  Also, you don't want to replace
the built-in template for elements because then you will copy all and
sundry.

One solution is to make use of modes:-

<xsl:template match="B">
 <xsl:apply-templates mode="copy" select="child::*/child::*"/>
</xsl:template>

<xsl:template match="*" mode="copy">
 <xsl:copy>
   <xsl:apply-templates mode="copy"/>
 </xsl:copy>
</xsl:template>

In this way you decide at what branch to start the recursive copy, and you
avoid the built-in template.
