[basex-talk] Need help to query

Hello, I need some help to query a database of thousands of xml files. They are structured only with elements with no attributes :

file1.xml <A> <B> <C>value</C> </B> <D> <E>text</E> </D> </A>

file2.xml <A> <B> <C>value</C> </B> <D> <E>text</E> </D> </A>

and so on file3.xml, file4.xml....

Having the value of the <C> element, I would like to have the text of the <E> element.

What is the good query to do this ?

Best regards

Florent
