XML Viewer Plus
Fast, private XML viewer for Firefox and Firefox for Android
XML Viewer Plus opens XML in Firefox, on desktop and Android, as a fast, searchable tree. It detects XML by content type, so URLs without .xml open too: REST APIs, RSS, Atom, SOAP, KML, GPX, sitemaps. Characters show correctly in any encoding: ISO-8859-1, Windows-1252, Shift_JIS, UTF-16. Large documents open in about a second. Search with text, regular expressions, XPath (namespaces included) or CSS selectors. Feeds get a reader view, and the source view is syntax-highlighted. Light and dark themes. No data collection. ...
