​​​​​​​​What does XML do?​


​​​​​​​​​​​Actually, XML does not do anything. Yes, that’s true.!! Sounds confusing ? Excellent..! XML is used to store data ​
​according to our database structure. It can not manipulate or change the data being stored. XML is software ​
​independent data storing and carrying language.​
​​
​For example:​
​​
​​
​​

    ​​​​​<CD>​​​​​​​​​
    ​​
    ​​
    ​​

​​

    ​​​​​<TITLE>Vande Matram</TITLE>​​​​​​​​​
    ​​
    ​​
    ​​​​​<ARTIST>A.R.Rehman</ARTIST>​​​​​​​​​
    ​​
    ​​
    ​​​​​<COUNTRY>India</COUNTRY>​​​​​​​​​
    ​​
    ​​
    ​​​​​<COMPANY>??</COMPANY>​​​​​​​​​
    ​​
    ​​
    ​​​​​<PRICE>55</PRICE>​​​​​​​​​
    ​​
    ​​
    ​​​​​<YEAR>1992</YEAR>​​​​​​​​​
    ​​
    ​​
    ​​

​​

    ​​​​​</CD>​​​​​​​​​
    ​​
    ​​
    ​​

​​
​​​​​As seen the above XML data is just storing the required data according to the user defined tags and doing NOTHING ​
​to them. Maybe now you are understanding the above statement.​
​​
​Actually, XML is used to separate data from HTML. Think of yourself developing a dynamic page for your website ​
​that let’s say displays the latest news about you. Now, if you use XML and store the data in another file, you would ​
​save yourself from updating the whole HTML page code every time you want to update the information. Just change ​
​the data of the XML file accordingly and safely.​
​Moreover, by using javascripts, you can easily play with the data of your XML files and create good dynamic pages.​
