Re: [xsl] Help with creating Task child of Task

[Wendell Piez <wapiez@xxxxxxxxxxxxxxxx>]

Hi Charles,

Alternatively, do this with modes.

The first time through the document, remove the reference-content by 
matching it with an empty template.

Then, from the template that directs this traversal from the top, 
select the reference-content for processing again, matching it in a 
special-purpose mode to create the new element.

So, something like:

<xsl:template match="task">
  <xsl:copy>
    <xsl:copy-of select="@*"/>
    <!-- going to copy the taskbody -->
    <xsl:apply-templates/>
    <!-- now going to make any reference-content into a new task -->
    <xsl:apply-templates select="taskbody/reference-content" mode="new-task"/>
  </xsl:copy>
</xsl:template>

<xsl:template match="reference-content"/>
<!-- dropping reference-content when we see it inside the old taskbody -->

<xsl:template match="reference-content" mode="new-task">
  <task>
    <title/>
    <taskbody>
      <context>
        <xsl:apply-templates/>
      </context>
    </taskbody>
  </task>
</xsl:template>

... plus the identity template to copy everything else.

Keep in mind that while it may appear that you are "opening" and 
"closing" elements, what you're really doing is grafting stuff onto 
the result tree. Using a second mode gives you a way of saying "don't 
attach it here" in one place and "attach it here" in another place.

Cheers,
Wendell
