Can someone help me with the following:
I have a table:
CREATE TABLE "HTS"."HTS_XML2"
( "ID" NUMBER,
"NAME" VARCHAR2(90 BYTE),
"FILENAME" VARCHAR2(400 BYTE),
"MIME_TYPE" VARCHAR2(48 BYTE),
"UPLOADED_BY" VARCHAR2(100 BYTE),
"CLOB_CONTENT" "HTS"."XMLTYPE"
)
In that table I have 1 row. Clob_content contains an xml file:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<microplateDoc xmlns="http://moleculardevices.com/microplateML";>
<fileVersion>2.0.7</fileVersion>
<experimentSection sectionName="Experiment#1">
<plateSection>
<plateType>PlateType</plateType>
<plateSectionName>Plate#1</plateSectionName>
<plateReadTime> 2:10 PM 8/27/2008
</plateReadTime>
<instrumentInfo>PLUS190PC ROM v1.21 Aug 18 2005</instrumentInfo>
</plateSection>
</experimentSection>
</microplateDoc>
I am trying to pull out the plateType value with:
select
extract(clob_content,'/microplateDoc/experimentSection/plateSection/plat
eType/text()')
from hts_xml2;
or
select
extractvalue(clob_content,'/microplateDoc/experimentSection/plateSection
/plateType')
from hts_xml2;
or any other iteration I've been able to think of.
How do I get at that value and if <plateType> occurs more than once in
the file how do I extract all occurrences of that value?
Thanks,
Chris
