Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable.

1 Creating - xml file

XML is a markup language, which means that content is enclosed by tags. In XML, elementtags are enclosed in angle brackets:

Copy 
<element>This is element text.</element>

A closing tag is indicated by a forward slash in front of the element name.

XML does not provide a set of predefined tags. Instead, you define your own tags and therelationships among the tags. This makes it possible to define and implement a contentstructure that matches the requirements of your information.

4 XML to DOM

In some cases, when having a text that corresponds to a XML format, it can be very useful to cover it as a DOM structure to extract node's information, attribute's values, etc.
