XML Format support

1. Check the version at chrome://extensions. Version 3.0.0 had a bug that kept the tree from appearing. It is fixed in 3.0.1.
2. Reload the page. Tabs that were already open when you installed or updated the extension only pick it up after a reload.
3. Check that XML Format is switched on at chrome://extensions.
4. Make sure the page is really XML. HTML pages, SVG images and other web pages are left alone on purpose.
5. If the XML has an error in it, Chrome shows its own error message and the tree does not appear.

Chrome does not let extensions run on its own pages, such as chrome:// addresses and the Chrome Web Store.

Chrome blocks extensions from local files unless you allow it. Go to chrome://extensions, click Details under XML Format, and turn on Allow access to file URLs. Then reload the tab with your file.

This is a known bug: the preview shows raw markup instead of a sample tree. Your settings still work. Click Save Changes and reload an XML page to see them.

XML Format is a rebuild of XML Tree by Alan Stroop, and the banner above the tree still shows that name. It is the same extension.

Double-click a tag to fold it to a single line, and again to expand it. Click an element, attribute, comment or processing instruction and its XPath appears in the Wonder Box at the top. Edit it if you like, then press Get Results to list every match. You can also paste XML into the Wonder Box and press Get Results to show it as a tree.

Click Options in the banner above the tree, or open the extension’s options from chrome://extensions. Pick your colors, font, size and display options, click Save Changes, and reload the XML page.

Put view-source: in front of the address, for example view-source:https://example.com/feed.xml. Chrome shows the raw file there without the tree.

No. Your XML is parsed and shown in your browser, the extension makes no network requests and has no analytics. The privacy policy has the details.

Open the puzzle piece menu in Chrome’s toolbar, click the three dots next to XML Format and choose Remove from Chrome. You can also remove it at chrome://extensions. XML pages then show in Chrome’s default view again, and your saved display preferences are removed with the extension.
