Editing the WSDL generated by a web service

Editing the WSDL generated by a web service

I have a basic web service that parses XML sent from a client. The web
service works fine but I was asked to remove elements from the WSDL file
generated by the web service. Is it even possible to do this?
Here are the first lines from the WSDL file:
<wsdl:definitions targetNamespace="localhost">
<wsdl:types>
<s:schema elementFormDefault="qualified" targetNamespace="localhost">
<s:element name="HTTPWebService">
<s:complexType/>
</s:element>
<s:element name="HTTPWebServiceResponse">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1"
name="HTTPWebServiceResult">
<s:complexType mixed="true">
<s:sequence>
<s:any/>
</s:sequence>
</s:complexType>
</s:element>
</s:sequence>
</s:complexType>
</s:element>
</s:schema>
</wsdl:types>
<wsdl:message name="HTTPWebServiceSoapIn">
<wsdl:part name="parameters" element="tns:HTTPWebService"/>
</wsdl:message>
Is it possible to remove the lines <s:element
name="HTTPWebServiceResponse"> and it's contents, and <s:element
name="HTTPWebServiceResponse">?
