How to remove xmlns from xml using java

Question

Hi,
<DLList xmlns="http://www.test.com/integration/feed" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Weather>
<StateName>Karnataka</StateName>
<ForecastName>Bagalkote</ForecastName>
<Humidity>89.9</Humidity>
</Weather>
<Weather>
<StateName>Karnataka</StateName>
<ForecastName>Devengiri</ForecastName>
<Humidity>89.9</Humidity>
</Weather>
</DLList>
The above xml needs to be decomposed using xsu.I am facing a small problem because the xml has namespaces.
How to remove the namespace using java to get the below xml
Note:I am using XSLT for the transformation.The XSLT tag is not identifying the <DLList> tag with name space
<DLList>
<Weather>
<StateName>Karnataka</StateName>
<ForecastName>Bagalkote</ForecastName>
<Humidity>89.9</Humidity>
</Weather>
<Weather>
<StateName>Karnataka</StateName>
<ForecastName>Devengiri</ForecastName>
<Humidity>89.9</Humidity>
</Weather>
</DLList>
Please help.Let me know if any other information is required
Thanks

Answer 1

OK, here goes :
For the example, I'll use a TB_DISTRICT table with the following structure :
create table tb_district (
sr_no number(3),
district_name varchar2(100)
);loaded with data from this page :
http://india.gov.in/knowindia/districts/andhra1.php?stateid=KA
and this XML document (one additional record compared to the one you posted) :
<DLList xmlns="http://www.test.com/integration/feed" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Weather>
<StateName>Karnataka</StateName>
<ForecastName>Bagalkote</ForecastName>
<Humidity>89.9</Humidity>
</Weather>
<Weather>
<StateName>Karnataka</StateName>
<ForecastName>Devengiri</ForecastName>
<Humidity>89.9</Humidity>
</Weather>
<Weather>
<StateName>Karnataka</StateName>
<ForecastName>Dharwad</ForecastName>
<Humidity>70.1</Humidity>
</Weather>
</DLList>In order to access the XML, I'll also use this Oracle directory object :
create directory test_dir as 'D:\ORACLE\test';Final relational tables are :
create table BUSINESS_TABLE
  STATE         VARCHAR2(30),
  DISTRICT_NAME VARCHAR2(30),
  HUMIDITY      NUMBER
);and
create table REJECT_TABLE
  STATE         VARCHAR2(30),
  DISTRICT_NAME VARCHAR2(30),
  HUMIDITY      NUMBER,
  ERROR_MESSAGE VARCHAR2(500)
);With XMLTable function, we can easily break the XML into relational rows and columns ready to use for DML :
SQL> alter session set nls_numeric_characters=". ";
Session altered
SQL>
SQL> SELECT *
  2  FROM XMLTable(
  3    XMLNamespaces(default 'http://www.test.com/integration/feed'),
  4    '/DLList/Weather'
  5    passing xmltype(bfilename('TEST_DIR','test.xml'), nls_charset_id('CHAR_CS'))
  6    columns
  7      state         varchar2(30) path 'StateName'
  8    , district_name varchar2(30) path 'ForecastName'
  9    , humidity      number       path 'Humidity'
10  )
11  ;
STATE                          DISTRICT_NAME                    HUMIDITY
Karnataka                      Bagalkote                            89.9
Karnataka                      Devengiri                            89.9
Karnataka                      Dharwad                              70.1
Then with a multitable insert, we load both the business table and the reject table (if the district name does not exist in TB_DISTRICT) :
SQL> INSERT FIRST
  2    WHEN master_district_name IS NOT NULL
  3      THEN INTO business_table (state, district_name, humidity)
  4                VALUES (state, district_name, humidity)
  5    ELSE INTO reject_table (state, district_name, humidity, error_message)
  6              VALUES (state, district_name, humidity, 'Invalid district name')
  7  WITH xml_data AS (
  8    SELECT *
  9    FROM XMLTable(
10      XMLNamespaces(default 'http://www.test.com/integration/feed'),
11      '/DLList/Weather'
12      passing xmltype(bfilename('TEST_DIR','test.xml'), nls_charset_id('CHAR_CS'))
13      columns
14        state         varchar2(30) path 'StateName'
15      , district_name varchar2(30) path 'ForecastName'
16      , humidity      number       path 'Humidity'
17    )
18  )
19  SELECT x.*
20       , t.district_name as master_district_name
21  FROM xml_data x
22       LEFT OUTER JOIN tb_district t ON t.district_name = x.district_name
23  ;
3 rows inserted
SQL> select * from business_table;
STATE                          DISTRICT_NAME                    HUMIDITY
Karnataka                      Dharwad                              70.1
SQL> select * from reject_table;
STATE                          DISTRICT_NAME                    HUMIDITY ERROR_MESSAGE
Karnataka                      Bagalkote                            89.9 Invalid district name
Karnataka                      Devengiri                            89.9 Invalid district name
