XML, which stands for eXtensible Markup Language, is rapidly emerging as the preferred technology to exhange structured data between systems. Wikipedia defines XML as a markup language that defines a set of rules for encoding documents in a format which is both human-readable and machine-readable. It is defined by the W3C's XML 1.0 Specification and by several other related specifications, all of which are free open standards. This presentation discusses how XML documents are exchanged in an SOA environment using SOAP and the importance of WSDL.
