XPATH 2.0 collection() with "?select=" (in eXist-db / XQuery)

Question

Using XPath 2.0 in eXist 4.4 and XQuery.

I have a series of documents in eXist-db directory /db/apps/deheresi/data which I want to retrieve with collection(), but using a wildcard or predicate to filter specifically-named documents.

For example, I'd like to get the documents that begin with ABC and end with .xml. I thought a wildcard like so ?select=ABC*.xml would work, but it's not returning the expected results.

collection("/db/apps/deheresi/data?select=ABC*.xml")

I also tried to apply a combination of starts-with and ends-with but to no success. I am no doubt overlooking something simple here.

Thanks in advance.

One way of doing this in exist

xquery version "3.1";
(: get document names :)
 let $doc-names := for $n in collection('/db/apps/deheresi/data')
 return
    util:document-name($n)

(: apply filter :)
 for $f in $doc-names[matches(., '^ABC.*\.xml$')]
 return
  $f
