Re: performace considerations for XSL while coding

  I am using -
  <xsl:variable name="..." >
  <xsl:copy-of select="...." />
  </xsl:variable>

  in my code. Do you think this hampers performance?


Yes.

It is much better to go <xsl:variable name="..."  select="..."/> if that
is what you mean, that essentially just makes a variable that references
into the input node set, whereas xsl:copy has to make new nodes with
new identities.

similarly
<xsl:variable name="x" select="2"/>
makes $x the number 2 but
<xsl:variable name="x">2</xsl:variable>
makes $x a result tree fragment corresponding to a node set consisting
of a root node containing a child text node with value the string "2".
This is harder to build and harder for the system to coerce back to
being the number 2 when you use it.
