Edit and save WSDL file

[keziakristina]

Hi all,

I want to edit the attribute of a WSDL file and then save it.
My WSDL look like below :

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" name="TestWSDL" targetNamespace="tns">
	<wsdl:types>
		<xs:schema targetNamespace="tns" elementFormDefault="qualified">
			<xs:include schemaLocation="[B][U]../GeneralException.xsd[/U][/B]"/>
		</xs:schema>
	</wsdl:types>
.....		
.....
</wsdl:definitions>

I want to edit the value of the attribute schemaLocation which its value in bold and underline.
I'm using C#. Anyone can help me?
Thanks
