ABSTRACT
Extensible Markup Language (XML) documents are simple case-sensitive text documents describing structured data. In XML, data are arranged in the form of a tree. Each node of the tree is called an element, which is syntactically represented as a start tag–end tag pair. Tags contain the element name enclosed between the less than (<) and greater than (>) symbols. The end tag also contains a trailing forward slash symbol. Each element may contain text or be empty. <elementName>text</elementName> <elementName></elementName>
