About This Tool

The tool analyzes XAML source to produce a machine-readable representation of its structure. It identifies elements, attributes, and namespaces, building a hierarchical model that can be exported as JSON for tooling, testing, or documentation. This supports scenarios such as code audits, migration planning, and automated validation within build pipelines. The parser accounts for common dialects used in WPF, UWP, and Xamarin.Forms, providing consistent output across platforms. The process is non-destructive and suitable for large codebases.
Conceptually, the input XAML is parsed into a tree, namespaces are resolved, and each node is annotated with its path and properties. The resulting JSON reveals parent-child relationships, attribute mappings, and any namespace hints that affect interpretation. Optional options allow depth-limited traversal or a compact representation for efficient downstream consumption.
This tool is valuable to developers, QA engineers, and automation engineers who need a dependable, repeatable view of UI definitions without requiring a local XAML parser installation. The unique value lies in its platform-agnostic JSON output, deterministic traversal order, and explicit diagnostics that facilitate rapid debugging and integration.
Core features include schema-aware validation, element-path generation, attribute extraction, and the capability to export either a full tree or a summarized view suitable for documentation and comparison tasks.

How to Use

  1. Provide inputs by pasting or uploading XAML code into the input area.
  2. Choose output format and options (e.g., JSON tree, element paths).
  3. Run parsing to generate the structured representation.
  4. Review the parsed tree, paths, and diagnostics.
  5. Export or feed the data into automation pipelines.

Frequently Asked Questions

Find Quick Answers

What XAML variants are supported?
The parser supports common XAML dialects including WPF, UWP, and Xamarin.Forms. It handles standard element trees, namespaces, and attributes, while providing diagnostics for unsupported constructs or nonstandard namespace usage.
Can the output be used in automation?
Yes. The primary output is a JSON tree that includes element names, attributes, and hierarchical paths suitable for ingestion by CI systems, documentation generators, or further code analysis steps.
How are invalid XAML structures reported?
Invalid XML or XAML syntax yields diagnostic messages with line and column references. The tool aims to provide a best-effort tree alongside errors, without crashing, to support partial analysis.
Are there limits on input size or performance?
Large XAML documents are processed with safeguards such as depth limits and chunked parsing where applicable. Performance scales with input size, and extremely large files may require batching for optimal results.
