Another Passthrough question

Hello:

I've got some XSL that contains this:

    <xsl:template match="/">
        <xsl:comment>#protect-top</xsl:comment>
        <xsl:apply-templates select="system-data-structure"/>
        <xsl:comment>#protect-top</xsl:comment>
    </xsl:template>

To transform to JSON.

The transform works fine in oXygen as well as when I test it in Cascade's editor. Here's what it displays:

<!--#protect-top-->{"system-data-structure":{...}}
<!--#protect-top-->

However, when I Preview a page that has the format applied, I get the following error:
An error occurred: Root element not set

I get a similar error in publish messages when I publish.

All pages that have this format use this template:

<!--#cascade-skip--><system-region name="DEFAULT"/><!--#cascade-skip-->

I've tried a number of things, including removing the cascade-skip from the template, and using protected in the format. So far, nothing has worked.

Any ideas?

Thanks!
Greg

   Hi Greg,

   It looks like you are very close, but your Template needs a little tweaking. Specifically, you still need a root node that surrounds your DEFAULT region to ensure it's valid XML.

   When you have a moment, try changing your Template to the following:

   <!--#cascade-skip--><pass-through><system-region name="DEFAULT"/></pass-through>
   

   To summarize, the <pass-through> element within the Template will allow you to work around the "root node" requirement for valid XML, and the #cascade-skip will remove that element on render. The #protect-top within your Format will move your content to the very top, resulting in a plain text file being generated.

   Please let me know if you have any questions.

   Thanks!
