Xwift — XML Viewer & Formatter av benjamin

Open an XML file — or the XML page you're already on — and actually read it.

Xwift turns raw XML into a clean, collapsible, syntax-highlighted tree, with a one-click pretty-print / minify source view. And when the XML is broken, it tells you exactly where and why — line and column — instead of dumping plain text or a blank page.

• Tree view — color-coded elements, attributes, text, CDATA, comments and processing instructions; expand or collapse everything in one click.
• Source view — re-indent (2 / 4 / tab) or minify, with line numbers and copy.
• Real validation — a tolerant parser that keeps going on broken input and lists every well-formedness problem with its line:column: mismatched and unclosed tags, duplicate attributes, unbound namespace prefixes, stray content, an unescaped &, a literal ]]>, and more. Click an error to jump to it.
• Handles big files — parsing runs off the main thread so the tab stays responsive where "load it all into the DOM" viewers stall.
• Namespaces done right — xmlns scopes are tracked and unbound prefixes flagged.

Built to respect you:
• Zero data collection. Everything runs locally. No network requests with your content, no account, no telemetry. Files you open never leave your browser.
• Minimal permissions. No host permissions, no <all_urls>, no tab snooping. It reads a page only the moment you ask it to.
• Zero dependencies, open source. The XML engine is hand-written — audit it at https://github.com/jjdoor/xwift
