XML : tools for re-indenting XML in batch mode

Question

I have a whole lot of XML files, badly indented.

I wish to write a script or use a tool which re-indents all the files.

Is there such a tool, or a nice library in a mainstream scripting language (preferred are Ruby and Python), or in Java ?

Answer 1

You are looking for an XML pretty printer.

Here is an online tool, that uses xmlpp under the hood.

Answer 2

Here's a large list of options to do it:

The main ones that I'd use are the xslt stylesheet, or HTML Tidy.
