XPath expressions are evaluated against all documents in a MarkLogic 
database:

/foo/bar

Will return all elements bar that are children of documents with a root 
node of foo.

collection("my-collection")/foo/bar

Will return all elements bar that are children of documents with a root 
node of foo that belong to the collection "my-collection."

xdmp:directory("/my-directory/","infinity")/foo/bar

Will return all elements bar that are children of documents with a root 
node of foo that are in a directory called "/my-directory/" or any of its 
descendent directories.

One difference between cts:search() and XPath is the ordering of 
documents. XPath returns documents in database order, whereas cts:search() 
returns documents in relevance order. It is possible to order your 
expressions by other values, but to do that you will need a FLWOR 
expression.

Finally, you can add cts:query constraints to your XPath expressions using 
cts:contains():

xdmp:directory("/my-directory/","infinity")/foo/bar[cts:contains(.,cts:and-query(("blue","red")))]

Will return all elements bar that are children of documents with a root 
node of foo that contain the words "red" and "blue" that are in a 
directory called "/my-directory/" or any of its descendent directories. 
Results will be returned in database order.

Hope this helps.

Kelly

Hi all,

I have used MarkLogic for two weeks, and I have managed to use XQuery 
against one XML document. And I could also use cts:search against plural 
XML 
documents. However I would like to search against plural documents by 
using 
XPath. Can I do it by using both cts:search and XQuery? If yes, could you 
tell me the examples of XQuery and XML documents?

Thanks and regards,
