How to create a dyanamic query in PL/SQL from XML

Question

Hi Forum,
I am having an XML file with tags. I am controlling my JSP page layout with these tags and it is working fine. But I need to send the Orange colour nodes to a pl/sql in the JSP page to construct the query as per the XML
<?xml version="1.0"?>
<Jobmanage>
<Customer name="StGeorge">
<Column>
<Name>QM_NUMBER</Name>
<Title>Job Number</Title>
<Width>10</Width>
<Font>Arial</Font>
<Size>10</Size>
<Align>center</Align>
<Display>Yes</Display>
<cloumn1> QM_NUMBER <column1>
</Column>
<Column>
<Name>QM_JOB_STATUS</Name>
<Title>Job Status</Title>
<Width>10</Width>
<Font>Arial</Font>
<Size>105</Size>
<Align>center</Align>
<Display>Yes</Display>
<column2>QM_JOB_STATUS</column2>
</Column>
<Column>
<Name>QM_USER_STATUS</Name>
<Title>User Status</Title>
<Width>10</Width>
<Font>Arial</Font>
<Size>10</Size>
<Align>center</Align>
<Display>Yes</Display>
<column3>QM_USER_STATUS</column3>
</Column>
</Customer>
</Jobmanage>
The select statement I am using n the JSP page is
SELECT Q.QM_NUMBER, Q.QM_JOB_STATUS, Q.QM_USER_STATUS FROM QMI Q WHERE ((Q.QM_JOB_STATUS IN (5, 6, 7, 8, 9, 10)) OR (Q.QM_JOB_STATUS IN (12) AND Q.QM_CLOSE_DATE >= SYSDATE - INTERVAL '6' MONTH))
Can you give me instructions how to create the above SQL statement dynamically as per the XML file. I want the select statement in a pl/sql
BEGIN
SELECT Q.QM_NUMBER, Q.QM_JOB_STATUS, Q.QM_USER_STATUS FROM QMI Q WHERE ((Q.QM_JOB_STATUS IN (5, 6, 7, 8, 9, 10)) OR (Q.QM_JOB_STATUS IN (12) AND Q.QM_CLOSE_DATE >= SYSDATE - INTERVAL '6' MONTH))
END
So, when ever the columns hirerachy changed in the XML file it should show theat effect in the PL/SQl. Thats hoe I am aiming to develop.
Thankx for you time.

I want the select statement in a pl/sql BEGIN
SELECT Q.QM_NUMBER, Q.QM_JOB_STATUS, Q.QM_USER_STATUS FROM QMI Q WHERE ((Q.QM_JOB_STATUS
IN (5, 6, 7, 8, 9, 10)) OR (Q.QM_JOB_STATUS IN (12) AND Q.QM_CLOSE_DATE >=
SYSDATE - INTERVAL '6' MONTH)) ENDThat doesn't make sense. Such a plsql block would not compile. What is your final goal you want to achieve with this?
