Intelligent Code Editor
A full-featured text editor built specifically for XML and related languages, with real-time visual feedback at every level.
- Syntax highlighting — Elements, attributes, values, comments, CDATA, processing instructions, and DOCTYPE
- Indent guides — Vertical lines that visualize nesting depth
- XPath breadcrumb — Real-time hierarchical path at the cursor position
- Tag matching — Automatic highlighting of opening/closing tag pairs
- Smart editing — Auto-close tags, auto-insert attribute quotes, synchronized tag renaming
- Status bar — Line, column, selection length, and encoding at a glance
Context-Aware Auto-Completion
Press Ctrl+Space to trigger completions. XML Edita analyzes the XSD content model at your cursor position and suggests only valid elements, attributes, values, and namespaces.
- Driven by XSD sequence, choice, and all content models
- Required attributes presented first
- Enumeration and simple type values for attributes
- Multi-schema and multi-namespace support
- Fuzzy matching on partial text
- Documentation side panel showing schema annotations
XSD Validation
Validate your documents against one or more XML Schemas. Errors and warnings appear in the console with click-to-navigate to the source location.
- Well-formedness check — Instant syntax verification
- Multi-schema validation — Support for multiple XSD files and namespaces
- Transitive resolution — Automatic import/include chain resolution
- Detailed diagnostics — Errors and warnings with line and column numbers
- 9 built-in schemas — XML Schema, XHTML, XSLT, XSL-FO, SVG, CML, and more for offline validation
XSD Composer — Visual Schema Editor
Design and explore XML Schemas visually. The interactive canvas renders the schema structure as a tree of typed nodes that you can expand, collapse, edit, and rearrange.
- Interactive canvas — Auto-layout, pinch-to-zoom, pan, minimap overlay
- 10 node types — Element, complexType, simpleType, sequence, choice, all, group, attributeGroup, attribute, any
- Global definitions sidebar — Browse, search, and filter all definitions by category
- Property inspector — Contextual panels for every node type with real-time editing
- Facet editor — Enumerations, patterns, restrictions (lengths, digits, bounds)
- Bidirectional sync — Edits in the Composer update the source XML and vice versa
- Export — Export the schema diagram as PNG or PDF
XSLT Transformations
Transform XML documents using built-in XSLT 1.0 or external processors. Configure stylesheets, parameters, and output options from a single dialog.
- Built-in XSLT 1.0 — Fast transformations via libxslt
- XSL-FO to PDF — Apache FOP pipeline: XML → XSL-FO → PDF (direct sale version)
- Auto-detect stylesheet — Reads the xml-stylesheet processing instruction
- Generate XML from XSD — Create a valid XML document from a schema with configurable options
Live Web Preview
Preview HTML, XHTML, and SVG documents in a native WebKit view that reloads automatically as you edit.
- Real-time rendering of HTML, XHTML, and SVG
- Preview of XSLT transformation results
- Automatic reload on every document change
- Native WebKit engine
XPath Evaluation
Evaluate XPath 1.0 expressions directly from the console. Results are displayed with their types — nodes, strings, numbers, or booleans.
- Typed results: node sets, strings, numbers, booleans
- Dedicated XPath tab in the console
- Quick iteration on queries against the current document
Project Management
Organize your XML files into projects (.xep) with nested groups, relative paths, and a shared Navigator Hub across all windows.
- Navigator Hub — Project tree + open files tabs, synchronized across windows
- Templates — 12 built-in templates (XML, XSD, XSL, XHTML, SVG, HTML, RSS, Plist, DTD, FO, CML) plus custom templates
- Recent projects — Quick access from the welcome screen and menu
- macOS integration — Autosave, version history, window state restoration
