Thanks for this, I was racking my head how to pretty-print some XML out of an XMLTYPE (it seems to lose all formatting as soon as you do an XMLTYPE function on it – e.g. UPDATEXML etc) and now I can just use the EXTRACT(‘/*’) ! Marvellous!

I have yet to find out what’s causing this is and what the solution/workaround is…

Hi Han,
I think this has to do with the SQL*Plus client that you use. At this site, I use SQL*Plus: Release 9.2.0.6.0 and it yields this result:
SQL> select XMLElement(“TheDate”, sysdate) from dual;

XMLELEMENT(“THEDATE”,SYSDATE)
—————————————————–

18-SEP-06

I do remember that we used to have an older version and it would show the XMLTypes as you describe.

I can’t use this statement, do i need to install extra XML stuff on the database ?

SQLPlus Release 9.0.1.4.0

SQL> select XMLElement(â€TheDateâ€, sysdate) from dual;

XMLELEMENT(â€THEDATEâ€,SYSDATE)()

Thanks Marco for this link to the Forums! Like I said my Google skills aren’t that great. I would never thought of using “pretty print” as a search term.
Changing the Long to a LOB? Probably. Maybe it would suffice to use VARCHAR2… I can’t get used to DBMS_LOB to manipulate Lobs…

For “extract” and “pretty print” see also http://forums.oracle.com/forums/search.jspa?objID=f34&q=extract+pretty+print

Alex,

wouldn’t it be better to use “clob” instead of your “long” datatype (l_str=long; – anyway will the long data type not be depricated, despite the fact that is a nasty datatype to handle)?.

The pretty print is caused because you used “extract(â€™/*â€™)” this (=extract) will give the layout you want, or not want, pretty print layout is the default behaviour for “extract” (you can alter this behaviour if you are using XML schemas and using a high Oracle 10.2.x version).
