Re: [xsl] filtering

[Mukul Gandhi <mukul_gandhi@xxxxxxxxx>]

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>
