XMLmind XML Editor Web Edition (XXEW for short) is a JavaScript implementation of XMLmind XML Editor Opens in new window running in the web browser, thus not requiring any installation on the user side.

Differences with the desktop application

Desktop Application Web Edition
Requires installing the application on the user's computer. (No need to install Java™. A private Java runtime is included in most software distributions.)
  • Requires installing a very recent web browser on the user's computer.
    At the time of this writing only very recent Blink-based browsers like Google Chrome or Microsoft Edge and Gecko-based browsers like Firefox are supported. Apple Safari, which uses the WebKit engine, is currently not supported.
  • Requires installing a Java 11+ runtime and XXEW distribution on the server side and running xxeserver, which is XXEW backend.
More about all these requirements in Chapter 2. How it works.
Multiple document user interface, adapted to authoring large, complex, modular, documents, including DITA maps or DocBook assemblies.
Single document user interface, adapted to authoring topics, articles, chapters, sections, etc.
Related restrictions:
  • XXEW has less toolbar buttons, less menus, less menu items than its desktop counterpart. It also has less keyboard shortcuts and its keyboard shortcuts are somewhat different.
  • XXEW cannot be used to insert element references (e.g. XInclude Opens in new window, DITA @conref) into a document.
No restrictions related to “local files”. When editing a document stored in a file which is local to the computer running the web browser, XXEW cannot render image references (e.g. DITA <image href="..."/>) and cannot transclude element references. The reason is that, for security reasons, a web browser gives a web application very little access to the local file system.
Multiple views of the document being edited may be displayed side by side. These views are the tree view, styled views (each view being specified using a different CSS stylesheet), with or without visible tags, and the XML source view. Only a single view of the document being edited is displayed at a time. It's possible to switch between the tree view and one of the styled views. Visible tags are not supported. The XML source view is not supported.
Spell checking is @lang/@xml:lang aware and automatically switches between dictionaries. Spell checking is implemented by the web browser, which is not convenient to use in the context of multi-lingual documents.
Has advanced import DOCX, paste from MS-Word and paste from web browser facilities. Can convert XML to a variety of formats (PDF, Web Help, EPUB, RTF, ODT, DOCX, etc.) Has no import or export facilities.
Has CJK (Chinese, Japanese, and Korean) support. Has right-to-left writing (Arabic, Persian, Hebrew, etc) support. No CJK or right-to-left writing support.
Is also a MathML Opens in new window WYSIWYG editor. MathML rendered on screen (by the web browser), but editable only using the tree view.
