You probably could use an XPath instead (ie. root/DocumentTypeName/AnotherDocumentTypeName).

As Jon says, it's possible (as always in Umbraco):

Change your "source" parameter to a textstring instead and change your XSLT to something like this:

<xsl:for-each select="$currentPage/ancestor-or-self::root//*[@nodeName = $source]/*[@isDoc and not(umbracoNaviHide = 1)]">

Thanks Jon and Chriztian, but ideally I want to display the source as the "nodeName" instead of the "nodeID".

I should have explained my scenario in full.

I have a section on my website called "Videos" that I include "video" doctypes. I have sub pages within this section displaying the child node video doctypes within them. However there are "video" doctypes in my "Projects" section and my "About Us" section. I only want to source video's from my "Projects" section so using the suggested method will include all "video" doctypes from any section.

Here's my structure:

About Us
----Our people
--------video

Videos
----News
--------video
--------video
----Safety
--------video
--------video
----Projects (This needs to display all the child nodes and only video doctypes from my "Projects" section)
--------video
--------video

Projects
----Company
--------video

Currently I've got it working well, but like I stated in my initial post I want my Macro the source to be displayed as the "nodeName" instead of the "nodeID".

Here's my code:
