What is XML Used For?

XML is one of the most widely-used formats for sharing structured information today: between programs, between people, between computers and people, both locally and across networks.

XML is for structuring data

Structured data includes configuration parameters, spreadsheets, address books, and  financial transactions.  XML is a collection of rules for creating text formats that allow you to organize your data. You don't need to be a programmer to use or master XML because it isn't a programming language.  XML makes it simple for a computer to create, read, and verify that the data structure is clear. XML avoids several of the most common language design blunders. It's expandable, platform-agnostic, and internationalized.

Accessibility

With XML, you categorize your data.  When data is separated, it is easier to retrieve when adjustments are required.  If you write both segments in HTML, you'll end up with sections that combine the formatting instructions with the data you want to show on the page. When it's time to update your information or edit an inventory record, you'll have to sift through a lot of code to discover a few lines. Separating data with XML makes modifications simple and quick.

Multiple Applications

Make a single data page that you may reuse over and over. When it comes to inventory cataloging, you only have to do it once. For that data, you can make as many display pages as you wish. XML allows you to generate multiple styles and formats from a single page of data.
In the end, XML is only a tool. It organizes your design work into useful divisions.  The language's simplicity eliminates the need for extensive expertise or an alphabet soup of credentials behind your name. XML saves time and organizes the design process.

XML Pretty Print

If you have an XML document that is not nicely formatted, you can use XML Notepad to reformat it into a pretty print layout. The XML pretty printer will output the XML with consistent indenting based upon the logical nesting depth of the tags. Quoting characters are made consistent, and new lines are inserted between tags. It is designed for XML that contains no mixed content, and the behaviour is undefined on encountering mixed content.
