Making a webservice based on XSD Schema

I am just beginner in making web service, i have following XSD Schema.

<?xml version="1.0"?>
<xs:schema xmlns:xs="http://ift.tt/tphNwY">
<xs:element name="Request">
<xs:complexType>
  <xs:all>
    <xs:element name="DeveloperKey" type="xs:string" />
    <xs:element name="Email" type="xs:string" />
    <xs:element name="Password" type="xs:string" minOccurs="0" />
    <xs:element name="Test" type="xs:boolean" />
  </xs:all>
</xs:complexType>
</xs:element>
</xs:schema>

Now i have to hit the specific URL like (http://ift.tt/1pMcT0X) along with xsd schema and their values (I have the developer key,email,password) how can i do this using PHP,JSON,CURL etc ??\

Thanks in Advance !!
