How It Works

This XML viewer and editor provides a dual-pane interface with a collapsible tree view on one side and syntax-highlighted text editor on the other. It makes navigating and editing complex XML documents intuitive and efficient.

The editing workflow:

Load XML: Paste or upload your XML document. It's parsed and displayed in both tree and text views.
Navigate with tree: Expand/collapse nodes to explore the document structure visually.
Edit in either view: Changes in the tree or text editor sync automatically with real-time validation.
Validate and export: Built-in validation catches errors. Download the edited XML when finished.

Features like search, XPath queries, and line numbers make working with large XML files manageable. The tree view shows element hierarchy at a glance.

When You'd Actually Use This

Editing Configuration Files

Modify XML config files for applications, servers, or development tools with visual structure guidance.

Debugging API Responses

Inspect and modify XML API responses to understand structure and test different values.

Working with SOAP Messages

View and edit SOAP envelopes with complex nested structures and namespaces.

Creating Test Data

Build XML test fixtures with proper structure for unit tests and integration testing.

Learning XML Structure

Understand document hierarchy and relationships through the visual tree representation.

Validating XML Documents

Check XML for syntax errors, unclosed tags, and structural issues before using in production.

What to Know Before Using

Changes aren't auto-saved

This runs in your browser. Copy your work or download before navigating away. Refresh loses unsaved changes.

Very large files may be slow

Documents with thousands of nodes may cause performance issues in the tree view. Consider splitting large files.

Validation is syntax-only

The tool checks well-formedness but doesn't validate against XSD schemas. Schema validation requires additional tools.

Tree and text views sync

Editing in one view updates the other. Invalid XML in text view may temporarily break the tree until fixed.

Namespaces are preserved

The editor maintains namespace declarations and prefixes. Be careful when editing prefixed elements.

Common Questions

Can I edit XML with namespaces?

Yes! The editor preserves namespace declarations and handles prefixed elements correctly. Just be careful not to break namespace references.

How do I search for specific elements?

Use the search function to find text anywhere in the document. Some editors also support XPath queries for structural searches.

Can I format/pretty-print my XML?

Yes, use the format/beautify function to add proper indentation and line breaks. Makes XML much more readable.

What happens if I create invalid XML?

Real-time validation highlights errors like unclosed tags or invalid characters. Fix errors before the tree view can display properly.

Can I collapse all nodes at once?

Most XML viewers have 'collapse all' and 'expand all' buttons for quickly changing the tree view density.

How do I add new elements?

In text view, just type. In tree view, right-click a node and select 'add child' or similar. Both methods sync automatically.

Can I view binary XML files?

No, this editor handles text-based XML. Binary XML formats require specialized tools to decode first.
