There are many text editors catered to programmers, and most of them offer some versatility in how many languages they can use.

Everyone has their own preference for which editor to use, but let us take a look at Notepad++.

It comes with color coding, line numbering, multiple tabs, and plugin support.

These features make it a lucrative tool for any kind of developer/programmer. It is widely used for XML and Java.

What are XML and XSD?

XML is the extensive markup language. It is primarily used to write XML files which is a markup file that contains a set of rules.

These rules are for encoding documents in a special format that both humans and machines can read. These XML files are used to transport and store data.

An XSD (XML schema definition) is a set of rules that describe how the XML file is formatted and what kind of content it has.

XML files are ‘validated’ against XSD files to make sure that their contents are used correctly and do not have any errors.

When validating the XML against the XSD, all the errors are highlighted. Highlighted errors can then be removed or corrected.

How to use Notepad++ for validating XML against XSD

Notepad++ does not come with XML support by default. In fact, for it to recognize XML you need to install a plugin first. Plugins can be easily installed in Notepad++, there are no complicated procedures involved.

First of all, you need to download and install Notepad++. A simple Google search will be enough to find its download link.

Then you need to install it. After installation, run Notepad++, click on ‘Plugins’, and then click on ‘Plugins Admin’.

Type out “XML” in the ‘search’ bar. Click on “XML tools” in the results and press Install.

Notepad++ will close, and an installer will download the plugin and install it automatically.

After the installation, ‘XML’ will be added to the “Languages” menu.

This will allow you to write using XML, with proper color coding and indentation.

Once you have written some sample XML and an XSD, to validate them you need to go to the 'plugins' drop-down menu, hover on 'XML tools', and then click 'validate now'.

You can also use the shortcut “Ctrl+Alt+Shift+M”.
