Is there any way to perform a LIKE operation with XQuery in the same way as with SQL?
I wan't to construct some "startswith", "endswith" and "contains"-expressions.
Example of what I want to achieve:
for $x in /user where $x/firstname LIKE '%xxx' return $x
for $x in /user where $x/middlename LIKE 'xxx%' return $x
for $x in /user where $x/lastname LIKE '%xxx%' return $x
Is there any way to achieve this in XQuery?
EDIT:
Got the answer to the question above. New problem:
Would there be any way to do this the opposite way around? I would like to run those queries with the sql equivalent NOT LIKE operator. Is this possible? It has to be in an FLWOR-expression
EDIT2:
Solved the problem. You can run fn:not(starts-with('123', '1')) and it returns false.

XPath 2.0 and XQuery 1.0 (as standardized by the W3C) have regular expression support with the matches function http://www.w3.org/TR/xpath-functions/#func-matches:
/user[matches(firstname, 'xxx$')]
And of course there are functions like starts-with and contains (both in XPath 1.0/2.0), and ends-with (only in XPath 2.0) that might suffice.
