XML Editor

The XML Editor is the core feature of the Free XML Toolkit. It provides a powerful and user-friendly interface for working with XML files.

Key Features

File Management

• Open & Save: Easily open existing XML files from your computer or save your work. The application remembers the last directory you used, making it convenient to access your files.
• New Files: Create new, empty XML documents from scratch.
• Drag & Drop: Simply drag and drop XML files from your file explorer directly into the editor to open them.
• Favorites System: Save frequently used files as favorites with custom categories and descriptions for quick access. See the Favorites System documentation for detailed information.

Editing Experience

  • Text Mode: Traditional code editor with advanced syntax highlighting and IntelliSense
  • Grid Mode: Table-like interface for structured data editing with direct cell manipulation
• Graphical Tree View: Interactive visual representation of XML structure with drag-and-drop editing capabilities
• Advanced Syntax Highlighting: Enhanced syntax highlighting with RichTextFX integration, supporting XML namespaces, attributes, and nested structures
• Code Folding: Intelligent collapse and expand functionality for XML sections to navigate large documents efficiently
• Context-Sensitive IntelliSense: Smart auto-completion that shows only relevant child elements based on your current XML context and loaded XSD schema, with ENTER key selection support

Formatting Tools

• Pretty Print: With a single click, you can format your XML into a clean, indented structure. This is useful for making messy or unformatted XML readable.
• Minify: This tool compresses your XML into a single line by removing all whitespace. This is useful for reducing file size for transmission or storage.

Validation

  • XSD (XML Schema Definition): Advanced validation against W3C XML Schema files with detailed error reporting and line-by-line feedback
  • Schematron: Business rule validation with custom constraints and advanced pattern matching
• Schema Features:
  • Automatic Schema Detection: Intelligent detection of schema references within XML files (xsi:schemaLocation, xsi:noNamespaceSchemaLocation)
  • Manual Schema Selection: Browse and select schema files with support for multiple schemas and namespaces
  • Continuous Validation: Real-time validation feedback as you type with error markers and status indicators
  • Validation Panel: Dedicated validation results panel with clickable error navigation
• Advanced Validation Features:
  • Multi-Schema Support: Validate against multiple XSD files simultaneously
