DBMS_XMLQuery problems

Question

The xmlquery is creating and extra "ITEM" tag when using the object view below.
Any Ideas?
Thanks
CREATE OR REPLACE VIEW sjs.arrest_obj_view
AS SELECT a.a_date AS "ArrestDate",
NVL(a.a_photo_num,'NULL') AS "PhotographNumber",
NVL(a.a_division,'NULL') AS "AgencyDivision",
'MODEL MAPPING PROBLEM' AS "ArrestType",
NVL(agcy.agcy_ori,'NULL') AS "ArrestingAgency",
a.a_id AS "ArrestNumber",
NVL(o.o_number,'NULL') AS "AssistingOfficerID",
'MODEL MAPPING PROBLEM' AS "CJTN",
CAST(MULTISET(SELECT l.lu_name AS "WeaponForce"
FROM sjs.arrestweapons awm,
sjs.lookuptable l
WHERE awm.a_id = a.a_id
AND awm.weapons_id = lu_id (+)) AS arrest_weapons_type)
AS "ArrestWeapons"
FROM sjs.arrest a,
sjs.agency agcy,

Hi Frank,
Please chech your object view definition.
are u sure that there will be sigle value populated in the set ArrestWeapons?? your definition says that there will be multiple values and thais is how xmlquery typically handles the nesting.
inside the <ArrestWeapons> ,there will be no of <ArrestWeapons_ITEM> nestings equal to the no of records.
if u do not want this item tag there or two options.
1)try canging the object view definition.i am not sure about your requirements of the xml query. the heriarchy can also be acheived by nested cursors and by objects/nested tables.
2)u will have to manipulate the clob while generating the xml file and delete the unwanted tags.
feel free to post any further queries...
