Re: [xsl] convert large array to several smaller arrays containing max N elements

[Wendell Piez <wapiez@xxxxxxxxxxxxxxxx>]

David,

This is where you code is broken:

At 05:14 PM 11/11/2003, you wrote:
>       <xsl:if test="position() mod 2 = '0'">
>          </topgroup>
>          <topgroup>
>       </xsl:if>

This is not well-formed XML. The parser is seeing the </topgroup> end tag 
here; its error message is complaining that it's the wrong end tag. The 
only end tag allowed where you have "</topgroup>" is </xsl:if>.

So, you ask, what do I do if I can't "close" an element and "open" another 
one? Hint: XSLT is not a set of string-writing routines, and it doesn't 
work by writing tags to the output. Instead, it builds trees. Instead of

> <xsl:template match="/">
>    <topgroup>
>    <xsl:for-each select="//WorkOrder/lineService">
>       <TEABTN>
>          <NPA><xsl:value-of 
> select="normalize-space(tpExistAcctBillTelNo/npa)"/></NPA>
>          <NXX><xsl:value-of 
> select="normalize-space(tpExistAcctBillTelNo/nxx)"/></NXX>
>          <XXXX><xsl:value-of 
> select="normalize-space(tpExistAcctBillTelNo/xxxx)"/></XXXX>
>       </TEABTN>
>       <xsl:if test="position() mod 2 = '0'">
>          </topgroup>
>          <topgroup>
>       </xsl:if>
>    </xsl:for-each>
>    </topgroup>
> </xsl:template>

you want something like

<xsl:template match="/">
  <xsl:for-each select="//WorkOrder/lineService[position() mod 2 = 1]">
   <topgroup>
     <xsl:for-each select=".|following-sibling::lineService[1]">
      <TEABTN>
         <NPA><xsl:value-of 
select="normalize-space(tpExistAcctBillTelNo/npa)"/></NPA>
         <NXX><xsl:value-of 
select="normalize-space(tpExistAcctBillTelNo/nxx)"/></NXX>
         <XXXX><xsl:value-of 
select="normalize-space(tpExistAcctBillTelNo/xxxx)"/></XXXX>
      </TEABTN>
  </topgroup>
  </xsl:for-each>
</xsl:template>

The difference between this and what you had is that it specifies a set of 
*nodes* to be added to the result *tree* -- not just write a bunch of tags 
(which hopefully will parse). Not incidentally, the stylesheet template 
itself is well-formed XML, and will parse.

It's completely different from, say, the way Javascript writes HTML tagging 
to browser windows.

Cheers,
Wendell
