XMLMind XML Editor

XMLMind XML Editor is a strictly validating, near‑WYSIWYG editor for XML‑based standards such as DocBook, DITA, XHTML5 and MathML. It enforces schema compliance while users the document’s visual layout, allowing technical writers, engineers and scholars to create large, modular documents with confidence that the output conforms to the chosen specification.

The editor includes extensive support for DITA 1.3 (including Lightweight DITA, XDITA, HDITA and MDITA), DocBook 5.1 assemblies, and XHTML5 features such as conversion of HTML page sets into EPUB, PDF, WebHelp or DOCX. It also provides a built‑in MathML editor and robust import/export facilities for DOCX, RTF, WML, ODT and other formats. Customization is possible through a well‑documented Java API or by end‑users without programming, and a web‑based edition runs entirely in the browser.

A free personal edition is available, alongside priced special editions for DITA and DocBook, and the product is targeted at users who need a reliable, schema‑aware XML authoring environment rather than a general‑purpose programming tool.
