Help - I've been struggling for hours with RenderMacroContent. I've read the posts here, but I can't get it to work.

First off I'm using V3 RC1, so maybe that's an issue.

I'm trying to render one macro from another, but keep receiving the error:
"Error parsing XSLT file: \xslt\xs_show_snippets.xslt"

The XSLT of this macro is:
Code:
<xsl:template match="/">
    <xsl:value-of select="umbraco.library:RenderMacroContent('&lt;?UMBRACO_MACRO macroAlias=&quot;mc_snippet_book_online&quot;&gt;&lt;/?UMBRACO_MACRO&gt;', @id)" />
  </xsl:template>


I've tried to get all the escaping of characters correct and have followed the guide from Heather at:
http://en.wikibooks.org/wiki/Umbraco/Reference/umbraco.library/RenderMacroContent

The macro "mc_snippet_book_online" simple is a test macro at the minute and just outputs "Hello World".

Can anyone help me at all please as I'm going insane.

Thanks

Damn! I'll try again as the post has cleverly interpreted all the escaping.

Code:
  <xsl:template match="/">
    <xsl:value-of select="umbraco.library:RenderMacroContent('&amp;lt;?UMBRACO_MACRO macroAlias=&amp;quot;mc_snippet_book_online&amp;quot;&amp;gt;&amp;lt;/?UMBRACO_MACRO&amp;gt;', @id)" />
  </xsl:template>

Woohoo! I've found a solution and a better way to do it if it helps.

First of all the updated code:
Code:
&lt;xsl:variable name=&quot;Macro&quot;&gt;
  &lt;![CDATA[&lt;?UMBRACO_MACRO macroAlias=&quot;mc_snippet_book_online&quot;&gt;&lt;/?UMBRACO_MACRO&gt;]]&gt;
&lt;/xsl:variable&gt;
&lt;xsl:value-of select=&quot;umbraco.library:RenderMacroContent($Macro, $currentPage/@id)&quot; disable-output-escaping=&quot;yes&quot; /&gt;


The problems I was having was by using @id as the second parameter. I've changed this to $currentPage/@id and that solved the problem.

Secondly I've found a quicker/clearer way to escape the macro code, but placing it into a variable as CDATA.

I hope that this helps someone else at some point.

Cheers to all
