Hi kelly,

[MarkLogic Dev General] RE: How to search plural documents by
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,
