Select into xmltype cuts tags

Question

Hello.
My query:
SELECT XMLELEMENT("Dataset", XMLATTRIBUTES('http://www.SDMX.org/resources/SDMXML/schemas/v1_0/generic' AS "xmlns:generic"),
XMLAGG(XMLELEMENT("generic:Series",
XMLELEMENT("generic:SeriesKey",
XMLELEMENT("generic:Value", XMLATTRIBUTES(SPR_EMS1 as "concept", CODE_EMS1 as "value")),
XMLELEMENT("generic:Value", XMLATTRIBUTES(SPR_EM2 as "concept", CODE_EMS2 as "value")),
XMLELEMENT("generic:Value", XMLATTRIBUTES(SPR_EMIS3 as "concept", CODE_EMS3 as "value"))
XMLELEMENT("generic:Attributes",
XMLELEMENT("generic:Value", XMLATTRIBUTES(EDI AS "concept", EDI_NAME AS "value")),
XMLELEMENT("generic:Value", XMLATTRIBUTES(NAME_PERIOD as "concept", TO_CHAR(MONTH_DATE, 'fmmonth') as "value"))
XMLELEMENT("generic:Obs",
XMLELEMENT("generic:Time", TO_CHAR(MONTH_DATE, 'YYYY')),
XMLELEMENT("generic:ObsValue", XMLATTRIBUTES(NUM as "value"))
INTO TAG
FROM
(SELECT MONTH_DATE, NAME_PERIOD, NUM, EDI, EDI_NAME, SPR_EMS1, CODE_EMS1, SPR_EMS2, CODE_EMS2, SPR_EMS3, CODE_EMS3
FROM EMS_001
WHERE (TO_CHAR(MONTH_DATE, 'YYYY') = OTCH_YEAR AND TO_CHAR(MONTH_DATE, 'MM') <= OTCH_MONTH) OR (TO_CHAR(MONTH_DATE, 'YYYY') = TO_CHAR(TO_NUMBER(OTCH_YEAR-1)))
ORDER BY MONTH_DATE, SEQ_CODE1, SEQ_CODE2, SEQ_CODE3);
It works good just for a certain number of returned rows. But when i select much more data from table this selection will be cut in any part of any tag.
Am i right that XMLTYPE has max length? How can i increase it?
Thank you.

when i select much more data from table this selection will be cut in any part of any tag.I also suspect it is a client issue:
e.g. in sql*plus you would have to set an appropriate LONG value:
SQL> set long 100
SQL> select xmltype('<x>' || lpad('x', 200, 'x') || '</x>') xml from dual;
XML
<x>xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
1 row selected.
SQL> set long 250
SQL> select xmltype('<x>' || lpad('x', 200, 'x') || '</x>') xml from dual;
XML
<x>xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxx</x>
1 row selected.
