XML is a markup language used to structure data in a way that is simple to read for people and to process automatically. The basis is to enclose data in tags whose tag names describe the data. Tags can be nested within tags to form a hierarchical structure. For example
<Customers>
<Customer>
<FirstName>Melony</FirstName>
<LastName>Chan</LastName>
</Customer>
<Customer>
<FirstName>Dilip</FirstName>
<LastName>Johnson</LastName>
</Customer>
</Customers>
In iVectorConnect the XML format is used for sending and receiving data in requests and responses. The letters XML stand for eXtensible Markup Language.
