What EditiX is
EditiX is a free, open-source XML editor and development toolkit for XML and related formats. It combines editing assistance and validation with XML comparison, XPath and XQuery support, and XSL-FO transformations. The XSLT editor and debugger covers versions 1.0, 2.0 and 3.0. Schema support includes DTD, XML Schema, Relax NG and Schematron, alongside a visual W3C XML Schema editor. EditiX also handles JSON and JSON Schema, HTML, CSS and SVG. Users can extend it with JavaScript, use its JavaScript DOM API, and create custom menus, toolbars and actions. Other tools include CSV and XLSX import, ZIP and archive support, multi-file search and XML project management. Downloads are available for Windows, macOS and Linux, with binaries and source builds; Java 8 or later is the stated runtime requirement. The GPL-3.0 version is free. A commercial license is available for companies needing closed-source use or internal or commercial modifications without copyleft requirements, and includes priority support and updates. An optional Extension Pack includes plugins for seven AI providers.
