Hi Jayaranga,
It is a little bit difficult to understand what maximum node count (of what?) you
need and for what purposes.

I'm assuming here that you need a large repository of "raw nodes" upon which to
build a non-recursive loop (the method of Wendell Piez).

The answer is that you may include in your stylesheet very large xml documents and
achieve as big a count as you may need.

For more information see:
http://www.vbxml.com/snippetcentral/main.asp?view=viewsnippet&lang=&id=v20010324001431

Any stuff can be included under a namespace-uri, different from 
the standard XSLT namespace-uri, like this:


<xsl:stylesheet version='1.0'
     xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
     xmlns:Shakespeare="Shakespeare">

  <Shakespeare:Hamlet>
    <!-- Hamlet goes here -->
  </Shakespeare:Hamlet>

  <!-- the rest of the stylesheet -->
</xsl:stylesheet>

 
As it can be seen, I included Jon Bosak's xml version of "Hamlet"
(http://www.stoa.org/bard/).
The following small template will return the number of nodes
(the maximum recursion depth that can be avoided) we can now use 
to organise non-recursive loops:


<xsl:template match="/">
  <xsl:variable name="st" select="document('')"/>
  <xsl:value-of select=" count($st//node() | $st//@* | $st//namespace::*)"/>
</xsl:template>
 
For the above stylesheet this number is: 32032.
As some people noted, this solution could be called an ugly one.
Or, to quote an xml fragment from our stylesheet, 

<SPEECH>
  <SPEAKER>MARCELLUS</SPEAKER>
  <LINE>Something is rotten in the state of Denmark. </LINE>
</SPEECH>

However, it is much more ugly to watch the slow and painful agony 
of IIS crashing only because we used a beautiful, deep recursive processing.

Hope this helped.

Cheers,
Dimitre Novatchev.
