Best Free XML Editors

​EditRocket is a comprehensive text and source code editor, offering a suite of XML editing tools designed to enhance productivity and ease of use. Its XML Validator allows users to check the syntax of XML files and validate them against schemas when the "check schema" option is selected. The XML Tag Navigator parses the editor's content, displaying XML tags in a clickable list that directs users to the corresponding tag locations within the document. The XML Sidekick provides tabs for coding inserts, tools, utilities, and the XML Tag Navigator, enabling quick insertion of XML constructs via buttons or customizable keyboard shortcuts. Additionally, EditRocket features XML Tag Completion, automatically inserting closing tags after typing an opening tag, with a configurable completion delay. Beyond XML-specific functionalities, EditRocket supports syntax highlighting for over 20 programming languages, and offers coding sidekicks and code builders.

​Xmplify is a 64-bit native application providing a fully XML-aware editing environment. It offers intelligent editing aids and suggestions by analyzing XML content in real-time. It features an outline view that displays the document's structure and updates automatically with edits. For documents with a DTD or XML Schema, Xmplify performs automatic validation and offers auto-completion based on the document's definition, displaying relevant documentation for each suggestion. In the absence of a specified DTD or Schema, Xmplify can automatically derive one to facilitate accurate auto-completion. Additional features include quick navigation to element definitions, support for XSL transformations with built-in and external processors, live web previews for (X)HTML documents, and powerful search capabilities using XPath and regular expressions.
