This will select all the StillRegions whose Text children contain the 
text 'tree'. However, I don't see any matching StillRegions in your 
example document.
If you turn this into
for $StillRegion in /Mpeg7//StillRegion[Text&='Sea']

you should get one result with the supplied sample.
Also make sure that the context collection of your query actually 
contains the documents you mean to search.
