How do i prevent getting a xml declaration in the xml response

Question

Hi,
I am using a soap call to access a webservice via plsql.
The xml response from the webservice starts as follows
<?xml version='1.0' encoding='UTF-8'?><soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">..............
I want to find ways to
1. either prevent the xml tag <?xml version='1.0' encoding='UTF-8'?> from being returned in the response.
2. or somehow convert the entire response to a string and remove it by substr (not sure about this)
The issue i am facing is that when i run a xmltype.extract on the xml to get a particular node i am getting the
ORA-31013: Invalid XPATH expression
when i remove the tag from the response (using hardcoded values) i get the right values back.
Any suggestions are welcome.

Hi,
The code extract with hardcoded values looks like this. Please note that i added quotes in the xml statement
'<?xml version=''1.0'' encoding=''UTF-8''?>which is not the case when oracle returns the xml and i guess thats the whole issue.
The code below runs perfectly. But when the entire procedure runs where the xml response is returned I get the error.
DECLARE
v_result XMLType;
v_xml XMLType;
v_request_id varchar2(100);
v_start varchar2(10);
v_end number(10);
