XML allows elements to be used to sort through database information readily.
XML stands for extensible markup language. XML was developed around 1996 and is a subset of SGML. It’s documents conform to SGML. XML was made less complicated than SGML to enable its use on the web. XML uses the ISO 10646 (Unicode) standard for encoding characters.
These are some advantages of using XML
You can define your own elements and thereby support a much wider variety of information display. XML may be used to describe chemical structures, or other scientific or artistic data that cannot be readily displayed using HTML.
Documents may be better organized into structures to allow for easier reference using and generating items like a table of contents.

There are many implementations of XML which utilize their own DTD (Document Type Definition). Many of them have different purposes; the biggest drawback to these various implementations of XML is that for the most part, it seems that you will need to read the DTD or read documentation about the XML implementation in order to use it.
