Need a solution for updating values in table

Question

My oracle version is 11 and my table name is nit_xml in which column name is cust_dtls
Data's of nit_xml table
<root>
<Cust_dtls> Nitesh </Cust_dtls>
</root>
I just want to update Nitesh to Nit ..
Its i inserted values through this way
INSERT INTO nit_xml
VALUES (
'<root>
<Cust_dtls> Nitesh </Cust_dtls>
</root>'
So i tried updating in my own way as like this way
UPDATE nit_xml
SET cust_dtls = '<root>
<Cust_dtls> Nitesh </Cust_dtls>
</root>'
WHERE cust_dtls = '<root>
<Cust_dtls> Nitesh </Cust_dtls>
</root>';
But not working so can anyone give me ideas on XML as how it works and is it possible or not to update through query .. Its note that i want to update column cust_dtls based on same column value and not any other datatype as number or varchar2 because based on other datatype it worked easily and second thing its i am using TOAD application so in that manual updation is possible which is fine but i need to update through query directly ..

This is new data I have inserted newly now ..
<H>
<cust_dtls>
<cust_name>Nitesh</cust_name>
<cust_phone>9790755104</cust_phone>
<cust_place>Ambattur</cust_place>
</cust_dtls>
<x2>
<cust_name>Bharathi</cust_name>
<cust_phone>123</cust_phone>
<cust_place>Mylapore</cust_place>
</x2>
</H>
Update query :
UPDATE nit_xml
SET cust_dtls = UPDATEXML (cust_dtls, '/root/cust_phone/text()', 132345)
WHERE TRIM (EXTRACT (cust_dtls, '/root/cust_phone/text()')) = 9790755104;
Its showing as 0 rows updated i cant find out any reason as what's happening .. I want to know also as why without TRIM its extraction is not possible ...Your XPath is incorrect. it should be /H/cust_dtls/cust_phone/text(). You dont have a tag as root. Its H.
