Final answer:
SOAP is the protocol specification that allows for the exchange of structured information between web applications based on WSDL files.
Step-by-step explanation:
The messaging protocol specification that defines how structured information can be exchanged between web applications and is created from WSDL files is SOAP (Simple Object Access Protocol). SOAP is a protocol specification for exchanging structured information in the implementation of web services in computer networks. WSDL (Web Services Description Language) files are XML-based documents that provide information on how a web service can be called, what parameters it expects, and what data structures it returns. SOAP uses these WSDL files to format messages according to the defined service.
SOAP (Simple Object Access Protocol) is the messaging protocol specification that defines how structured information can be exchanged between web applications and is created from WSDL files. SOAP uses XML (eXtensible Markup Language) to format the data being sent. It is widely used in web services and is compatible with different programming languages and platforms.
