<a href="http://www.firstobject.com/dn_editor.htm" rel="noreferrer">Firstobject's free XML editor for Windows is called foxe</a> is a great tool. 

Open or paste your XML into it and press F8 to indent (you may need to set the number of indent spaces as it may default to 0).

It looks simple, however it contains a custom written XML parser written in C++ that allows it to work efficiently with very large XML files easily (unlike some expensive "espionage" related tools I've used).

From the product page:

<blockquote>
 The full Visual C++ source code for this firstobject XML editor
 (including the CDataEdit gigabyte edit control MFC component) is
 available as part of the Advanced CMarkup Developer License. It allows
 developers to implement custom XML handling functions such as
 validation, transformation, beautify, and reporting for their own
 purposes.

If you use Notepad++, I would suggest installing the <a href="http://sourceforge.net/project/showfiles.php?group_id=189927&amp;package_id=264094" rel="nofollow noreferrer">XML Tools</a> plugin. You can beautify any XML content (indentation and line breaks) or linarize it. Also you can (auto-)validate your file and apply XSL transformation to it.

Download the latest zip and copy the extracted DLL to the plugins directory of your Notepad++ installation. Also, download the External libs and copy them to your %SystemRoot%\system32\ directory.

Advanced Conventional Formatting [Update]

<a href="https://github.com/pgfearo/xmlspectrum" rel="nofollow noreferrer">XMLSpectrum</a> is an open source syntax-highlighter. Supporting XML - but with special features for XSLT 2.0, XSD 1.1 and XPath 2.0. I'm mentioning this here because it also has special formatting capabilities for XML: it vertically aligns attributes and their contents as well as elements - to enhance XML readability.

The output HTML is suitable for reviewing in a browser or if the XML needs further editing it can be copied and pasted into an XML editor of your choice

Because xmlspectrum.xsl uses its own XML text parser, all content such as entity references and CDATA sections are preserved - as in an editor.

<img src="https://i.stack.imgur.com/LBiFy.png" alt="enter image description here">

Note on usage: this is just an XSLT 2.0 stylesheet so you would need to enclose the required command-line (samples provided) in a small script so you could automatically transform the XML source. 

Virtual Formatting

<a href="http://qutoric.com/xmlquire" rel="nofollow noreferrer">XMLQuire</a> is a free XML editor that has special formatting capabilities - it formats XML properly, including multi-line attributes, attribute-values, word-wrap indentation and even XML comments.

All XML indentation is done without inserting tabs or spaces, ensuring the integrity of the XML is maintained. For versions of Windows later than XP, no installation is needed, its just a 3MB .exe file.

If you need to print out the formatted XML there are special options within the print-preview, such as line-numbering that follows the indentation. If you need to copy the formatted XML to a word processor as rich text, that's available too.

[Disclosure: I maintain both XMLQuire and XMLSpectrum as 'home projects']

blocks|key|818022|text|不是直接的答案，但很高兴知道:缩进之后，请确保随后处理格式化的XML的解析器和应用程序不会产生不同的结果。White+space+is+often+significant+in+XML和大多数符合规范的解析器将其冒泡到应用程序中。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|818023|entityMap|0|LINK|mutability|MUTABLE|url|http://xml.silmaril.ie/whitespace.html^0|1H|13|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

Not directly an answer, but good to know nevertheless: After indenting, please make sure that the parser(s) and application(s) which will subsequently process the formatted XML will not yield different results. <a href="http://xml.silmaril.ie/whitespace.html" rel="nofollow noreferrer">White space is often significant in XML</a> and most conforming parsers bubble it up to the application.

If you are a programmer, many XML parsing programming libraries will let you parse XML, then output it - and generating pretty printed, indented output is an output option.

Try <a href="http://prettydiff.com/" rel="nofollow">http://prettydiff.com/</a> The algorithm is similar to HTML Tidy, but is more complete. The program is written entirely in JavaScript, so you don't have to install anything.

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
