I recently created a macro that allows users to pull the value of a query key into the TinyMCE content. There are two properties on the macro.

• "queryString" defines the query key the user is trying to pull. 
• "htmlCode" defines the HTML the user would like to output. Users use a token in place of the query string value.

Code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
<xsl:stylesheet 
  version="1.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
  xmlns:msxml="urn:schemas-microsoft-com:xslt"

Exslt.ExsltSets ControlData TokenDates ">


<xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:param name="currentPage"/>
<xsl:variable name="queryString" select="/macro/queryString"/>
<xsl:variable name="stringValue" select="umbraco.library:RequestQueryString($queryString)"/>
<xsl:variable name="htmlCode" select="/macro/htmlCode"/>
<xsl:variable name="formattedCode" select="Exslt.ExsltStrings:replace($htmlCode, '[%%stringvalue%%]', $stringValue)"/>
    
<xsl:template match="/">
<xsl:if test="$stringValue != ''">
<xsl:choose>
<xsl:when test="$htmlCode != ''">
<xsl:value-of select="$formattedCode" disable-output-escaping="yes"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$stringValue"/>
</xsl:otherwise>
</xsl:choose>
</xsl:if>  
</xsl:template>
</xsl:stylesheet>

This macro works perfectly on a template, however, whenever I try to insert "html" into the textstring property of the macro, I receive an error when saving the page node. This isn't the first time I've had issues inserting html into a macro in TinyMCE and received an error. The html I was inserting was a very simple <a href>

Error 1:

All my content disappears and it is replace with: [tidy error]

Error 2:

            
Server Error in '/' Application.

Has anybody else had troubles with this? It doesn't seem to matter if I use ascii codes for the html and/or if I use single quotes vs. double quotes.

Any thoughts?

Thanks!
