XSLT: Loop selecting two elements at a time

Question

I have a bunch of xml documents where the author chose to represent a set of cartesian points like this:

  0&l         


        

Answer 1

Sure there is a generic way:

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

  <xsl:template match="row">
    <set>
      <xsl:apply-templates select="
        col[position() mod 2 = 1 and following-sibling::col]
      " />
    </set>
  </xsl:template>

  <xsl:template match="col">
    <point x="{text()}" y="{following-sibling::col[1]/text()}" />
  </xsl:template>

</xsl:stylesheet>

Output for me:

<set>
  <point x="0" y="0" />
  <point x="1" y="1" />
</set>
