About This Tool

The MXML Editor helps Flex teams ensure correct UI descriptions by validating MXML structure and namespaces. It accepts MXML code, applies XML validation, and enforces MXML-specific constraints to prevent runtime issues. The tool returns a structured report with actionable diagnostics and optional fixes. Conceptually, it parses the input as XML, enforces MXML rules, and offers templates for common components to accelerate scaffolding. The workflow benefits developers, architects, and QA by delivering precise, line-accurate feedback and reusable patterns for consistent interfaces. Core features include syntax validation, root element checks, namespace verification, and exportable corrected code. Optional features cover lint-like rules, diff generation, and templates for typical layouts (Application, View, Panel, Form). Use cases span prototyping, code reviews, and CI checks to certify MXML conformance before compilation. The tool targets MXML 1.x used by modern Flex SDKs and provides compatibility guidance where feature gaps exist. By delivering structured diagnostics and minimal, safe refactors, it lowers debugging cost and accelerates iteration across teams.

How to Use

Provide inputs: paste MXML source code and optional SDK version.
Run validation: parse and verify root, namespaces, and nesting.
Review outputs: inspect errors, warnings, and suggestions.
Apply changes: modify code or export corrected snippet.
Validate again: run a second pass to confirm resolution.

Frequently Asked Questions

Find Quick Answers

What does the tool validate?

It validates MXML syntax, root element correctness, namespace usage, tag nesting, and common attribute constraints. It does not compile or execute code, but provides precise diagnostics to guide corrections.

Can it handle large projects?

Yes, it analyzes code fragments or full files and returns structured diagnostics. For very large files, performance scales with input size, and results are delivered in a staged report to preserve responsiveness.

Does it require internet access?

The core validation operates client-side in the browser and does not require a server call. It does not perform compilation or runtime execution and can function offline where allowed.

Can it export fixes?

Yes. The tool can export a corrected code snippet or a patch/diff to help developers apply changes in their source control workflow.

Which MXML versions are supported?

The validator targets MXML 1.x commonly used by Flex SDK 3.x–4.x. It reports unsupported constructs and provides guidance for migration or alternative patterns within that scope.
