Few thoughts:
1) If you place the script transformer method on the entity named "x"
and then pass the ${topic_tree.topic_id} to that as an argument, then
shouldn't you have everything you need to work with x's row? Even if
you can't look up at the parent, all you needed to know was the
topic_id and based on that you can edit or not edit x's row ...
shouldn't that be sufficient to get you what you need to do?
2) Regarding the manner in which you are trying to use the following
xpath syntax:
forEach="/gvpVideoMetaData/mediaItem[@media_id='${topic_tree.topic_id}']"
There are two other closely related thread that I've come across:
(a)
http://lucene.472066.n3.nabble.com/DIH-Enhance-XPathRecordReader-to-deal-with-body-FLATTEN-true-and-body-h1-td2799005.html
(b)
http://lucene.472066.n3.nabble.com/using-DIH-with-mets-alto-file-sets-td1926642.html
They both seemed to want to use the full power of XPath like you do
and I think that in a roundabout way they were told utilize the xsl
attribute to make up for what the XPath was lacking by default.
Here are some choice words by Lance that I've extracted out for you:
====
"XPathEntityProcessor parses a very limited XPath syntax. However, you
can add an XSL script as an attribute, and this somehow gets called
instead."

There is an option somewhere to use the full XML DOM implementation
for using xpaths. The purpose of the XPathEP is to be as simple and
dumb as possible and handle most cases: RSS feeds and other open
standards.
Search for xsl(optional)

I hope you can make some sense of this, I'm no expert, but just
thought I'd offer my 2 cts.
