RE: RE: [xsl] How to implement an array

[Wendell Piez <wapiez@xxxxxxxxxxxxxxxx>]

Imrran,

As you surmised, your problem is in your second template:

> <xsl:template match="Table1/Item" mode="celldata">
>   <xsl:variable name="Table1" select="."/>
>   <tr>
>   <xsl:for-each select="./*">
>   <xsl:variable name="tval" select="text()"/>
>   <xsl:for-each select="$Table1Struct">
>     <xsl:variable name="ItemName" select="string(name(.))"/>
>     <xsl:if test="count($Table1//*[name(.)=$ItemName]) &gt; 0">
>       <td><xsl:value-of select="$tval"/></td>
>     </xsl:if>
>   </xsl:for-each>
>   </xsl:for-each>
>   </tr>
> </xsl:template>

Essentially what's messing you up is that you are iterating over your 
lookup table nodes ($Table1Struct) for *each* of the child nodes of your 
Item, and every time, you're creating <td> output if *any* child 
(descendant actually, as you have it) of your Item has the name you're 
looking for. Usually it will, and you are performing this test 
(count(Item/*) * count($TableStruct)) times.

It's tricky and confusing. In order to get the logic right, you actually 
have to invert it. First iterate over the lookup nodes in $Table1Struct, 
creating a <td> for each one. Then its value: you want the value of that 
child of your Item that passes your name test; if there is none, presumably 
(this being HTML) you want a placeholding non-breaking space.

This template will do this:

<xsl:template match="Table1/Item" mode="celldata">
  <xsl:variable name="thisitem" select="."/>
    <tr>
      <xsl:for-each select="$Table1Struct">
        <td>
          <xsl:value-of select="$thisitem/*[name()=name(current())]"/>
          <!-- selects that child of the Item whose name is the name of
               the $Table1Struct node we're looking at -->
          <xsl:if
             test="not($thisitem/*[name()=name(current())])">&#160;</xsl:if>
          <!-- if there is none, gives us a space -->
        </td>
      </xsl:for-each>
  </tr>
</xsl:template>

Please ask about anything mysterious here.

Cheers,
Wendell
