RE: Out OF Memory Exception for Large XML data

Yes, this looks like one that's amenable to serial processing. Something
like:

 <?xml version="1.0" encoding="UTF-8"?>
 <xsl:stylesheet version="2.0"

     <xsl:param name="_userName"/>
     <xsl:param name="_password"/>
     <xsl:param name="_class"/>
     <xsl:param name="_identifier"/>
     <xsl:param name="_subject"/>
     <xsl:variable name="apos">'</xsl:variable>

     <xsl:template name="main">
       <DB>
         <xsl:apply-templates select="f:suppliers()"/>
       </db>
     </xsl:template>

     <xsl:function name="f:suppliers"

     </xsl:function>

     <xsl:template match="dbo.VW_Ref_Supplier_2_TPL_Supplier[Ref_Status !=

    </xsl:template>

    <xsl:template match="*"/>
</xsl:stylesheet>
