Well-formedness should probably only allow XML documents.
I think the point of this function is to determine whether a cast to
xml will throw an error. The behavior should probably match exactly
whatever test would be applied there.
Maybe there should be
xml_is_well_formed()
xml_is_well_formed_document()
xml_is_well_formed_content()
I agree that consistency with SQL/XML is desirable, but for someone
coming from the outside, the unqualified claim that 'foo' is well-formed
XML might sound suspicious.
What about making the function sensitive to the XML OPTION, such that:
test=# SET xmloption TO DOCUMENT;
SET
text=# SELECT xml_is_well_formed('foo');
xml_is_well_formed
--------------------
f
(1 row)
test=# SET xmloption TO CONTENT;
SET
text=# SELECT xml_is_well_formed('foo');
xml_is_well_formed
--------------------
t
(1 row)
with the inverse for DOCUMENTS? To me this makes the most sense as it makes the
function behave much more like the other xml functions.
