Hi Wonsuk, all,

If we consider the YouTube XML response [1] as a basis for the XPath expressions specified in the corresponding mapping table, they are not valid for the following properties

targetAudience -> here media:rating is not under media:content but under media:group. this is not specified in the table.

compression -> media:content is not directly a child of item, but of media:group

duration -> same issue as with compression

format -> same issue as with compression

publisher -> complete different XPath

i hope this clarifies things a little bit.

Cheers.
