XML Editor Features¶

Last Updated: November 2025 | Version: 1.0.0

This page describes the advanced features available in the XML Editor.

Schematron Integration¶

Schematron validation panel

What is Schematron?¶

Schematron lets you create custom validation rules for your XML documents. While XSD schemas validate the structure, Schematron validates business rules - for example, "if field A contains X, then field B must not be empty."

How to Use Schematron¶

Open an XML file in the XML Editor
In the sidebar, find the "Schematron Rules" section
Click the "..." button to select a Schematron file (.sch)
The validation results appear in the sidebar
Enable "Continuous Schematron validation" to check as you type

Saving Schematron Files as Favorites¶

Save frequently used Schematron files for quick access: - Click the star icon to add to favorites - Organize files in custom categories like "Business Rules" - Access saved rules from any editor via the Favorites dropdown

Auto-Completion (IntelliSense)¶

IntelliSense Popup Auto-completion suggestions popup

Smart Element Suggestions¶

When you type < in the editor, a popup shows only the elements that are valid at your current position based on your XSD schema.

How It Works¶

Type < - A popup appears with valid element options
Use arrow keys - Navigate through the suggestions
Press Enter - Insert the selected element
Press Escape - Close the popup

Auto-Closing Tags¶

When you type an opening tag like <element>, the editor automatically adds the closing tag </element> and places your cursor between them.

Grid Editor Mode¶

Changes made in either mode are synchronized automatically.
