What is XML Format?

Browsers show XML as a dense block of text, or not at all. XML Format takes over when the page in your tab is an XML document (RSS and Atom feeds, sitemaps, SOAP and REST responses, config files and exports) and turns it into a readable, interactive tree.

It is a maintained Manifest V3 rebuild of XML Tree by Alan Stroop, open source under the Mozilla Public License 2.0.

How it works

Open any XML address and the tree appears. Double-click a tag to fold it. Click a part of the document and its XPath appears in the Wonder Box at the top, ready to edit. Press Get Results to list every match. XPath runs on your browser’s own engine.

The options page lets you pick the color of every node type, the font, size and indent, and turn line wrapping, the banner, the XML declaration and clickable links on or off.

Local files

To view .xml files from your computer, open the extension’s details page in Chrome and turn on Allow access to file URLs.

Who it’s for

Developers reading API responses and config files
SEO specialists checking sitemaps and feeds
Anyone who has ever opened an XML file and seen a wall of text

Features

Color-coded tree for elements, attributes, values, text, CDATA, comments, processing instructions and namespaces
Hover highlight shows where an element and its parents open and close
Fold anything: double-click a tag to collapse it to a single line, and again to expand it
Click for XPath: click an element, attribute, comment or processing instruction and its path appears in the Wonder Box
Run queries: type an XPath 1.0 expression and list every match, with the document’s namespace prefixes
Paste and view: paste XML into the Wonder Box to render it as a tree on the spot
Make it yours: colors for every node type, font, size, indent and your own CSS rules

What it doesn't do

Send your XML, or anything else, to a server of ours or anyone else’s
Include analytics, tracking or an install ping
Require an account, login or sign-up
Change HTML, SVG or other non-XML pages: everything else is left alone

Permissions

Every permission this extension asks for, and why it needs it.

storage

Saves your viewer preferences (colors, fonts, display options and custom CSS) with chrome.storage.sync, so Chrome can sync them between your own browsers.

<all_urls>

XML can be served from any address, including file:// URLs. On each page the extension checks whether the document is XML and, only if it is, replaces it with the tree view. Nothing from any page is stored or sent.

Privacy first

XML Format collects nothing. Your XML is parsed and shown in your browser, and the extension makes no network requests. Your display preferences sync with your Chrome profile, and we never see them.
