Populate collection type from XMLType

Question

Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
PL/SQL Release 11.1.0.7.0 - Production

NLSRTL Version 11.1.0.7.0 - Production
Please bear with me as I'm new to this XML DB thing and also this is my first post.
I'm trying to populate collection type from XMLType. I was able to populate a table from XMLType but
couldn't figure out a way to populate the collection type. Here is the description of my problem:
Object Type:
CREATE OR REPLACE TYPE DOC_ROWTYPE AS OBJECT
     REFERENCENUMBER VARCHAR2(255),
     REQID NUMBER(12),
     REQDETID NUMBER(12),
     FROMAMOUNT VARCHAR2(31),
     TOAMOUNT VARCHAR2(31),
     TOACCOUNTID NUMBER(12),
     TOACCOUNTNUMBER VARCHAR2(35),
     FROMACCOUNTID NUMBER(12),
     FROMACCOUNTNUMBER VARCHAR2(35),
Collection Type:
CREATE OR REPLACE TYPE DOC_TABLETYPE IS TABLE OF DOC_ROWTYPE;
I have a physical table which is created when I registered a schema.
A table (Temp_Result) got created with column SYS_NC_ROWINFO$ which is of XMLType.
As you can see this is only a temporary table which will store the response XML which I want to finally get it to collection type.
XML to parse:
<code>
<TFSResponse>
<TFS>
<refNumber>12345</refNumber>
<reqId>123</reqId>
<reqDetId>111</reqDetId>
<fromAmount>20</fromAmount>
<toAmount>20</toAmount>
<fromAccount>
<accountId>22222</id>
<accountNumber>12345678</number>
</fromAccount>
<toAccount>
<accountId>33333</id>
<accountNumber>123456789</number>
</toAccount>
</TFS>
.... many TFS Tags
</TFSResponse>
</code>
So each object in the collection is one TFS tag.
Any advice on how to implement this?
