XSLT Fix: XSLT Polyfill, XML Viewer & XSLT Tester

XSLT polyfill: styled XML sitemaps, RSS feeds and e-invoices render again, XSLTProcessor works, plus an XML viewer and XSLT tester.

XSLT Fix is an XSLT polyfill, XML viewer and XSLT tester for Chrome. XML pages styled with XSL look the way they were designed again, any other XML file opens in a searchable viewer, and web apps that use XSLTProcessor keep working. It is also an e-invoice viewer: open an XML invoice in Chrome and read it as a printable invoice. When an XML sitemap, RSS feed, product feed, invoice or report relies on an XSL stylesheet and Chrome shows it as raw XML, XSLT Fix renders it with its stylesheet again. There is nothing to set up: install it and reload the page. XSLT POLYFILL • Renders every XML page that links a stylesheet with <?xml-stylesheet type="text/xsl" ...?>: XML sitemaps from any CMS, SEO plugin or generator, RSS feeds, catalogs and reports • Opens XML e-invoices, such as Peppol invoices, as a readable, printable invoice: with the stylesheet they carry, or with a built-in invoice view when they have none • Amounts and units follow your language's number format, and e-invoices that a server sends as plain text open too • Uses libxslt, the XSLT 1.0 engine Chrome itself used, compiled to WebAssembly • Supports xsl:import, xsl:include, document(), embedded stylesheets, legacy encodings, iframes, strict Content-Security-Policy and sitemaps with tens of thousands of URLs • Page scripts and styles run after the transform, so sortable tables keep working • Restores XSLTProcessor for web apps with one click, only on the sites you choose XML VIEWER • Collapsible tree with syntax colours, search, XPath and a node inspector • Table view of repeating records with sorting and filtering; export XML to Excel, CSV or JSON • Reading view for RSS and Atom feeds • Formatted or minified source with line numbers; points at the exact line when XML is not well-formed • Opens local XML files, folders and .zip archives, and XML served as plain text • To show local XML files, turn on "Allow access to file URLs" for XSLT Fix in Chrome's extension settings XSLT TESTER An XSLT editor and tester: XML and XSLT side by side with live preview, parameters, xsl:message output and an XPath tester. One click switches between the tester and the XML viewer. SITEMAPS, FEEDS AND MORE • Sitemap analysis: every URL with its lastmod, images and hreflang links, plus a status check for each URL • Podcast feeds play right in the reading view • Right-click a link to open it in the XML viewer or the XSLT tester, or select XML on any page to view it • JSON files open as XML • Light and dark themes. Companies can configure it with a managed policy PRIVATE AND SAFE • Everything runs in your browser. No data is collected or sent anywhere: no analytics, ads, accounts or remote code • Works only on the sites you allow and asks before it reads a new one • Same rule as Chrome's own XSLT: a stylesheet must come from the same site as the XML. A stylesheet that runs longer than 15 seconds is stopped • Turn it off for one site or everywhere. Alt+Shift+X switches between the styled page and its XML source Available in 15 languages.
