XQuery all files under a specific directory?

Question

Can I use XQuery to query all XML files under a specific directory? All the XML files have the same structure.

Also, from what I have seen you can XQuery many files but you need to write the names of them in the query. In my case, I need to query 500 XML files with quite different names each. So Is there a way I can say:

for $x in doc("ALL files under a specific directory")/Foo
return $x/Something

Answer 1

For MarkLogic:

for $x in cts:search(fn:doc()/Foo, cts:directory-query("/target/directory/"))
return $x/Something

Answer 2

Use the collection() function.

In its Saxon implementation, one can use:

collection('file:///a/b/c/d?select=*.xml')
