XMLQUERY

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

The XMLQUERY() function allows for extracting content from an XML document using XQuery or XPath

SELECT xmlquery('/doc/x'
  PASSING xmlparse(DOCUMENT '<doc><x>content</x></doc>')
  RETURNING CONTENT
)
FROM dual
create.select(xmlquery("/doc/x")
        .passing(
            XML.xml("<doc><x>content</x></doc>")
        ))
      .fetch();

The result would look like this:

+----------+
| xmlquery |
+----------+
| content  |
+----------+

This example using jOOQ:

xmlquery("/doc/x").passing(xml("<doc><x>content</x></doc>"))
