Question

Is there a free XML formatting (indent) tool available where I can past an XML string and have it formatted so I can read the XML document correctly?

Thanks

Edit ~ I am using XML Notepad on Windows XP.

Answer 1

I believe that Notepad++ has this feature.

Edit (for newer versions)
Install the ‘XML Tools’ plugin (Menu Plugins, Plugin Manager)
Then run: Menu Plugins, Xml Tools, Pretty Print (XML only – with line breaks)

Original answer (for older versions of Notepad++)

Notepad++ menu: TextFX -> HTML Tidy -> Tidy: Reindent XML

This feature however wraps XMLs and that makes it look ‘unclean’. To have no wrap,

• open C:\Program Files\Notepad++\plugins\Config\tidy\TIDYCFG.INI,
• find the entry [Tidy: Reindent XML] and add wrap:0 so that it looks like this:

 [Tidy: Reindent XML]  input-xml: yes  indent:yes  wrap:0
