Questions on extending the OOwriter-PlugIn to support HowTos

Hi Ross,

I'm trying to extend your OOWriter-Plugin to support HowTos and
so far it looks quite easy to do.

1. Changed OpenOffice-common2Forrest to insert some HowTo Header Info
   by adding the quoted sections:

  <!--+
      | start transforming 
      +-->
  <xsl:template match="/">
    <document>
      <header>
        <title>
          <xsl:choose>
            <xsl:when test="/office:document/office:meta/dc:title = '' or not(/office:document/office:meta/dc:title)">
              <xsl:value-of select="$filename"/>
            </xsl:when>
            <xsl:otherwise>
              <xsl:value-of select="/office:document/office:meta/dc:title"/>
            </xsl:otherwise>
          </xsl:choose>
        </title>

>         <!-- Abstract is required field in HowTos, so always create it and fill with description field  -->
>         <xsl:choose>
>                 <abstract>
>                         <xsl:when test="/office:document/office:meta/dc:description = '' or not(/office:document/office:meta/dc:description)">
>                         </xsl:when>     
>                         <xsl:otherwise>
>                         <xsl:value-of select="/office:document/office:meta/dc:description"/>
>                 </xsl:otherwise>
>                 </abstract>
>         </xsl:choose> 
>         
>         <!-- last modified date -->
>         <last-modified-content-date date="format-dateTime({/office:document/office:meta/dc:date}, '[Y]-[M]-[D]')"/>


        <xsl:call-template name="style"/>
      </header>
      <xsl:apply-templates select="//office:body"/>
    </document>
  </xsl:template>
  
  <!--+
      | create the body 
      +-->
  <xsl:template match="office:body">
    <body>

       <!-- This is special for HowTo-Documents. Will make this
            conditonal as soon as it is working  -->

>             <xsl:when test="/office:document/office:meta/dc:title = '' or not(/office:document/office:meta/dc:title)">

>               <xsl:value-of select="/office:document/office:meta/dc:title"/>

      <xsl:apply-templates select="key('rootChildren', generate-id())"/>
      <xsl:apply-templates select="text:h[@text:level='1']"/>      
    </body>
  </xsl:template>


2. I used and tested the OO-Plugin before modifying the file in the
   plug-ins-dir then changed above file and re-ran Forrest

   Funny thing is, nothing changes. It still compiles w/o errors, but
   none of the elements show. Tried and called the document.xml and
   it's not there either.

 Do I need to somehow reload plugins after I've changed
 stylesheets or where is my mistake here?

This will always put an abstract element in regardless of whether the it 
is needed. This may be your intention since this would still be legal 
XDoc and it makes sense. However, it is confusing to read because of the 
way you have nested the elements. Would read better (at least for me) as:

<abstract>
   <xsl:choose>
     ...
   </xsl:choose>
</abstract>

In addition the choice is not really necessary. If there is no 
dc:description element then the result of the <xsl:value-of...> would be 
empty anyway, so you can simply do:

<abstract>
     <xsl:value-of select="/office:document/office:meta/dc:description"/>
</abstract>
