XPath can describe such queries //*[matches(local-name(.), "foo"] However, that won’t scale for a large database because that XPath will require reading the documents themselves, rather than an index, like you’d have with a word-query, for example. I’m tracking this request and other similar ones, but I can’t make any promises about if and when we might add this capability to the database. In the meantime, I’d suggest you do some sampling. Select a small(ish) number of documents, randomly or by some other query logic and do some XPath inquiry on that smaller set. Something like: distinct-values( cts:search(collection(), cts:and-query(()), ("unfiltered","score-random"))[1 to 100] //*[matches(local-name(.), "Address$")]/xdmp:path(.) ) where I’m getting the distinct paths of all of the elements whose local names than end with the string “Address” (e.g. StreetAddress, FullAddress). Again, this type of query will be expensive on a large set of documents. I’ve limited my input to the first 100 randomly selected. If you have more smarts about the query you could do to select the universe of documents, even better (cts:and-query(()) means select everything).

Either using a FLOWR expression or cts:search. i.e. I would like to find all elements with a name that contains a wildcarded string because I'm unsure of the name of an element or where it is. And the most useful think I can think of to return would be the path to all elements (or attributes?) that contain that string. I found this document<http://developer.marklogic.com/blog/name-is-a-code-smell> that talks about name() vs local-name() or node-name(), and these return a QName, and I found xdml:path which would return a path given a node, so what I think I need is something like node-name but returns the node which I could pass to xdml:path. Otherwise I'm aware of term lists and the universal index but I can't find out how to query them. I guess I'm looking for something akin to the USER_TAB_COLUMNS dictionary table in Oracle.
