A WSDL Client for a StockQuotes.wsdl file

When writing client apps for wsdl files the standard library for input/output alongwith parsers-wsdl, schema, and xml are put into use. The below program uses a WSDL c++ web services client library-WSDLPULL to create web services client for a StockQuotes.wsdl xml file. Methods such as setWSDLUri, setOperation, setValue and getValue insert and retrieve data from the xml and make it available to the client application.
