Re: whats the best way to create and use values for lo

One of the basic XSLT design patterns is about maintaining useful
programming data structures within the XSLT code.

XSLT allows to have arbitrary global scope elements belonging to a namespace
different from the XSLT namespace. Within such elements one can put any data
structure, which may be used in the transformation.

Here's a simple example of this technique that shows how to solve the
current problem:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:myStruct="my:Struct"
 exclude-result-prefixes="myStruct">

 <xsl:output method="html" indent="yes"/>

 <xsl:variable name="vmaxCols" select="2"/>
 <myStruct:section1>
   <col1>20</col1>
   <col2>30</col2>
   <col3>10</col3>
   <col4>40</col4>
 </myStruct:section1>

 <myStruct:section2>
   <mycol1>30</mycol1>
   <mycol2>20</mycol2>
   <mycol3>40</mycol3>
 </myStruct:section2>

  <xsl:template match="section1 | section2">

  <table border="1">
    <tr>
      <xsl:for-each
      select="document('')/*/myStruct:*
                    [local-name() = name(current())]/*
                                [position() &lt;= $vmaxCols]">

       <td width="{.}"><xsl:value-of select="."/></td>
      </xsl:for-each>
    </tr>
  </table>

  </xsl:template>
</xsl:stylesheet>


When the above transformation is applied on this source.xml:

<t>
  <section1>
    <row col1="x1" col2="y1" col3="z1"/>
    <row col1="x2" col2="y2" col3="z2"/>
    <row col1="x3" col2="y3" col3="z3"/>
    <row col1="x4" col2="y4" col3="z4"/>
  </section1>
  <section2>
    <row mycol1="x1" mycol2="y1" mycol3="z1"/>
    <row mycol1="x2" mycol2="y2" mycol3="z2"/>
    <row mycol1="x3" mycol2="y3" mycol3="z3"/>
  </section2>
</t>

the wanted result is produced:

<table border="1">
   <tr>
      <td width="20">20</td>
      <td width="30">30</td>
   </tr>
</table>

<table border="1">
   <tr>
      <td width="30">30</td>
      <td width="20">20</td>
   </tr>
</table>
