RE: filtering

Thanks Jeni and Mukul.
I chose to adopt some of Jeni's version, since it required the least
modification to my own implementation, but it seems that Mukul's version is
to favour in the long run.

Thanks for the quick response :-)

Sincerely,
Daniel

Here is a generic solution I wrote! A downside though;
it relies on node-set function..

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
exclude-result-prefixes="msxsl">

<xsl:output method="xml" indent="yes"
encoding="UTF-8"/>
	
<xsl:template match="/root">
  <root>
    <xsl:variable name="rtf">
       <xsl:for-each select="row">
	 <xsl:variable name="curr_row" select="."/>
	 <xsl:variable name="x">
	   <xsl:for-each select="column">
	     <xsl:if test="position() = /root/header/*">
	       <xsl:if test="normalize-space(.) = ''">
	         1
	       </xsl:if>
	     </xsl:if>
	   </xsl:for-each>
	 </xsl:variable>
	 <xsl:if test="not(contains($x, '1'))">
	   <success>
	     <xsl:for-each select="/root/header/*">
		<xsl:element name="{name()}">
		  <xsl:value-of select="$curr_row/column[position()
= current()]"/>
		</xsl:element>
	     </xsl:for-each>
	   </success>
	 </xsl:if>
       </xsl:for-each>
     </xsl:variable>
     <flow>
	<total_in><xsl:value-of select="count(row)"
/></total_in>
	<total_out><xsl:value-of select="count(row) -
count(msxsl:node-set($rtf)/*)" /></total_out>
     </flow>
     <xsl:copy-of select="msxsl:node-set($rtf)/*"/>
   </root>
</xsl:template>

</xsl:stylesheet>

Mukul
