QXmlEdit

QXmlEdit is a cross‑platform XML editor built on Qt libraries, offering a hierarchical, customizable view of XML elements and fast navigation through large document structures. It supports splitting very large XML files into fragments, visual comparison of XML and XSD files, and includes specialized modes for XSL and SCXML editing. The tool provides XPath‑based searching, Base64 data handling, and various visualization styles such as columnar, map, and graphical views, along with session management and formatting options.

The editor is aimed at developers and users who need to inspect, edit, and compare XML documents, especially when working with extensive files or schemas. Its features like visual compare, data anonymization, and custom visualization make it suitable for tasks ranging from routine editing to detailed schema analysis. QXmlEdit is distributed under the LGPL V2 license, with source code and binary installers available for macOS, Windows, and many Linux distributions.
