macro in content in xslt

XSLT

I have some content (using Blog4Umbraco) that is editable with the richText editor, and into which users can insert a macro (the Indsæt video macro). If I render out the content via template, the macro is interpretted correctly and the video shows up in the blog posting.

I also have an XSLT / Macro (called blogListPostsWithOneMain) with the following:

  <xsl:template name="showpostfirst">
    <xsl:param name="post" />
    <div class="entry post publish author-{$post/@writername} tag-boat tag-lake {umbraco.library:FormatDateTime($post/@updateDate, 'yYYYY mMM')} y2008 m10 d17 h04">
      <h2 class="entry-title" id="post-{$post/@id}">
        <a href="{umbraco.library:NiceUrl($post/@id)}"
        title="Permalink to {$post/@nodeName}">
          <xsl:value-of select="$post/@nodeName" />
        </a>
      </h2>
      <div class="entry-date">
        <abbr class="published"
        title="umbraco.library:ShortDate($post/@updateDate">
          <xsl:value-of select="umbraco.library:LongDate($post/@updateDate)" />
        </abbr>
      </div>
      <div class="entry-content">
        <xsl:value-of select="$post/data [@alias = 'summaryMedium']"
        disable-output-escaping="yes" />
      </div>
<-- SNIP -->
    </div>
  </xsl:template>

When the template renders, pulling in this macro, which in turn pulls in the content 'summaryMedium' (that itself contains a macro), the resulting output is invalid. It contains something along the lines of:

<?UMBRACO_MACRO maxwidth="300"
sourceurl="http://vimeo.com/11480419" macroAlias="OEmbed"
maxheight="250" />

(ie it looks like it's just pulling the macro reference from the content, and not rendering it)

Is there a way to get this internal macro to render?

thanks in advance

Hi Jonathan

Try this

 <xsl:value-of select="umbraco.library:RenderMacroContent($post/data [@alias = 'summaryMedium'])"
        disable-output-escaping="yes" />

Hi Dan

Thanks for that. My updated XSLT saves fine in umbraco (no validation errors), but when outputting on the web page returns:

Error parsing XSLT file: \xslt\BlogListPostsWithOneMain.xslt

Also, I looked briefly at RenderMacroContent at http://en.wikibooks.org/wiki/Umbraco/Reference/umbraco.library/RenderMacroContent but my understanding was that this was for explicitly rendering a macro (ie you need to provide a macro to render) as opposed to rendering an XML node that may or may not contain a macro. Maybe I'm wrong? And, just because, I'm including my full XSLT below. look for ""

Thanks

Jonathan

Apologies! I should have known better, as I ran up against this very problem myself when using my own insert video package. As far as I can remember, I had to find a way to get the rich text editor content back in the templates and out of xslt...
