How to pretty print XML from the command line?

Question

Related: How can I pretty-print JSON in (unix) shell script?

Is there a (unix) shell script to format XML in human-readable form?

Basically, I want it to transform the following:

<root><foo a="b">lorem</foo><bar value="ipsum" /></root> 

... into something like this:

<root>     <foo a="b">lorem</foo>     <bar value="ipsum" /> </root>

xmllint

This utility comes with libxml2-utils:

echo '<root><foo a="b">lorem</foo><bar value="ipsum" /></root>' |     xmllint --format - 

Perl's XML::Twig

This command comes with XML::Twig perl module, sometimes xml-twig-tools package:

xmlstarlet

This command comes with xmlstarlet:

echo '<root><foo a="b">lorem</foo><bar value="ipsum" /></root>' |     xmlstarlet format --indent-tab 

tidy

Python

Python's xml.dom.minidom can format XML (works also on legacy python2):

echo '<root><foo a="b">lorem</foo><bar value="ipsum" /></root>' |     python -c 'import sys; import xml.dom.minidom; s=sys.stdin.read(); print(xml.dom.minidom.parseString(s).toprettyxml())' 

saxon-lint

You need saxon-lint:

echo '<root><foo a="b">lorem</foo><bar value="ipsum" /></root>' |     saxon-lint --indent --xpath '/' - 

saxon-HE

You need saxon-HE:

 echo '<root><foo a="b">lorem</foo><bar value="ipsum" /></root>' |     java -cp /usr/share/java/saxon/saxon9he.jar net.sf.saxon.Query \     -s:- -qs:/ '!indent=yes'
