How to remove xmlns attribute from XML tag?

Question

Hello!
I have a XMLType document:
--- P R O B L E M # 1 ---
<?xml version="1.0" encoding="windows-1257" ?>
<RESPONSE xmlns="http://testserver" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://testserver response.xsd">
<DATA REQUEST_ID="111">
<ENTITY name="PACKAGE_001">
<ATTRIBUTE name="PERS_ID" value="1111" />
<ATTRIBUTE name="FIRST_NAME" value="OLGA" />
<ATTRIBUTE name="SURNAME" value="NOVIKOVA" />
</ENTITY>
</DATA>
</RESPONSE>
I very need to remove from RESPONSE tag all addition information. Result I need is:
<?xml version="1.0" encoding="windows-1257" ?>
<RESPONSE>
<DATA REQUEST_ID="111">
<ENTITY name="PACKAGE_001">
<ATTRIBUTE name="PERS_ID" value="1111" />
<ATTRIBUTE name="FIRST_NAME" value="OLGA" />
<ATTRIBUTE name="SURNAME" value="NOVIKOVA" />
</ENTITY>
</DATA>
</RESPONSE>
What can I do in this situation? My Oracle version is 9.2.
--- P R O B L E M # 2 ---

<?xml version="1.0" encoding="windows-1257" ?>
<MY_RESPONSE>
<RESPONSE xmlns="http://testserver" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://testserver response.xsd">
<DATA REQUEST_ID="111">
<ENTITY name="PACKAGE_001">
<ATTRIBUTE name="PERS_ID" value="1111" />
<ATTRIBUTE name="FIRST_NAME" value="OLGA" />
<ATTRIBUTE name="SURNAME" value="NOVIKOVA" />
</ENTITY>
</DATA>
</RESPONSE>
</MY_RESPONSE>

Maybe the problem#1 can be solved with a simple pl/sql using REPLACE statement. start with the <RESPONSE and look for the end > and get the entire string and replace that with only <RESPONSE> or maybe you can achieve this using xmldom to delete the attributes as part of the element.
PRoblem#2 can be solved in this way.
select xmlelement("MY_RESPONSE",
xmltype('<RESPONSE xmlns="http://testserver" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://testserver response.xsd">
<DATA REQUEST_ID="111">
<ENTITY name="PACKAGE_001">
<ATTRIBUTE name="PERS_ID" value="1111" />
<ATTRIBUTE name="FIRST_NAME" value="OLGA" />
<ATTRIBUTE name="SURNAME" value="NOVIKOVA" />
</ENTITY>
</DATA>
</RESPONSE>')).GetClobVal()
