Dynamic table columns

[Alastair Growcott <al...@pipstechnology.co.uk>]

Hiya, all.

I have an XSL table that describes the attributes of none or more
objects. Because there are so many attributes, I want the attributes to
be the row headers with one column per object.

What XSL do I need to convert this to a FOP table of the same sort? I
can do some re-structuring of the XSL data if absolutely necessary.

E.g. my XSL file contains;

<object>
<attr1>hello</attr1>
<attr2>there</attr2>
<attr3>all</attr3>
<attr4>you</attr4>
<attr5>nice</attr5>
<attr6>helpful</attr6>
<attr7>people</attr7>
</object>
<object>
<attr1>I</attr1>
<attr2>could</attr2>
<attr3>really</attr3>
<attr4>really</attr4>
<attr5>use</attr5>
<attr6>some</attr6>
<attr7>help</attr7>
</object>

And I need this displayed as;

Attr1		hello		I
Attr2		there		could
Attr3		all		really
Attr4		you		really
Attr5		nice		use
Attr6		helpful	some
Attr7		people	help

Thanks very much in advance.

Alastair.

Questions regarding XSLT are best asked on the XSL list
(see below).

For you problem, try:

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
   xmlns:fo="http://www.w3.org/1999/XSL/Format">
   <xsl:template match="objects">
     <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
       <fo:layout-master-set>
         <fo:simple-page-master master-name="page"
           page-width="20cm" page-height="30cm">
           <fo:region-body/>
         </fo:simple-page-master>
       </fo:layout-master-set>
       <fo:page-sequence master-reference="page">
         <fo:flow flow-name="xsl-region-body">
           <fo:table table-layout="fixed">
             <fo:table-column column-width="35mm"/>
             <fo:table-column column-width="35mm"/>
             <fo:table-column column-width="35mm"/>
             <fo:table-body>	
               <xsl:variable name="objects" select="object"/>
               <xsl:for-each select="object[1]/*">
                 <xsl:variable name="name" select="name()"/>
                 <xsl:variable name="index" select="position()"/>
                 <fo:table-row>
                   <fo:table-cell>
                     <fo:block>
                       <xsl:value-of select="$name"/>
                     </fo:block>
                   </fo:table-cell>
                   <xsl:for-each select="$objects">
                     <fo:table-cell>
                       <fo:block>
                         <xsl:value-of select="*[$index]"/>
                       </fo:block>
                     </fo:table-cell>
                   </xsl:for-each>
                 </fo:table-row>
               </xsl:for-each>
             </fo:table-body>
           </fo:table>
         </fo:flow>
       </fo:page-sequence>
     </fo:root>
   </xsl:template>
</xsl:stylesheet>

     <attr3>all</attr3>

   <object>
     <attr1>I</attr1>
     <attr2>could</attr2>

     <attr5>use</attr5>
     <attr6>some</attr6>
     <attr7>help</attr7>
   </object>
</objects>


The XSLT is very brittle (think about it). There are more
general solutions available in the archives of the XSL
list
