Does formatting change the content?

In two ways worth knowing about. Whitespace around a text node is trimmed, so an element padded out to line up in your editor comes back tight. And entities are resolved by the parser and then re-escaped for only & , so ' comes back as a plain apostrophe and é as é. Element order, attributes, comments and CDATA are untouched, and any element mixing text with child tags is copied through exactly as it arrived.

How it works

XML Formatter and Validator: Pretty Print or Minify

Paste XML to indent it from the parsed document tree, or minify it back down. Comments, CDATA and the XML declaration survive, mixed content is left alone, and errors quote the parser’s own message.

What this does

Re-indents the parsed document tree, so this is a real pretty-print rather than a regex patch
Mixed content is reproduced verbatim, re-indenting an element that holds both text and child tags would change what it says
Comments, CDATA sections, processing instructions, the DOCTYPE and the XML declaration all come through

FAQ

Editors tolerate what XML does not. The usual culprits are a bare & that should be written &, a stray < inside text, mismatched or unclosed tags, an undeclared namespace prefix, or more than one root element in the file. The error banner repeats the parser’s own message with its line and column, which is normally within a character of the real problem.
