Re: [xsl] Select nodes with equal position

[Dimitre Novatchev <dnovatchev@xxxxxxxxx>]

This transformation shows how to avoid evaluating the position in an
xsl:variable:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
 
 <xsl:output omit-xml-declaration="yes"/>
  
  <xsl:template match="/">
    <xsl:for-each select="/*/*/entry">
      <xsl:value-of select=
         "/*/colspec[position() 
        = 
         count(current()/preceding-sibling::entry)+1]/@colname"/>
      <xsl:text>&#xA;</xsl:text>
    </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>

When performed on the original xml source document:

<table>
  <colspec colname="c1"/>
  <colspec colname="c2"/>
  <colspec colname="c3"/>
  <row>
    <entry colname="c1">r1_1</entry>
    <entry colname="c2">r1_2</entry>
    <entry colname="c3">r1_2</entry>
  </row>
</table>

the correct result is produced:

c1
c2
c3


Cheers,
