RE: Preserving inline elements when using string funct

Hi Marcus,

By saying "inline element" I was intending to illustrate more of what I am
trying to achieve in my output than how I'm thinking of my data structure.
I didn't write a DTD, but if I did, it would show a mixed content element
something like this:

<!ELEMENT bodytext (#PCDATA , link*)>
<!ELEMENT link (#PCDATA)>
<!ATTLIST link url CDATA #REQUIRED>

I'm trying to see what you're getting at. I'm thinking of it as "process the
child element this way, then process the parent element another way," but I
think you are suggesting that I think more like "process the parent element
content before the child element, then process the child element, then
process parent element content after the child element." Is that right?

Sorry, I should have had that code in my initial mail. I've tried a few
different ways to set the node context, but what's below is what I'm using
now. I'm not sure of the terminology, but I guess I'm using the two
templates in a pipeline. (Note that the 'string' paramater name is not an
accurate description of what I'm actually trying to store in that parameter
in this use of the template.)

<xsl:template name="textProcess">
    <xsl:for-each select=".">
      <xsl:call-template name="paragraphs">
           <xsl:with-param name="divClass" select="'para'" />
           <xsl:with-param name="string" >
              <xsl:call-template name="embeddedLinks" />
          </xsl:with-param>
      </xsl:call-template>
    </xsl:for-each>
</xsl:template>

Thanks,
