Intelligent XML Cleaner & Visualizer

This tool helps Android developers and QA engineers clean stale accessibility node information from UI XML dumps.

Features

• Active-Based Sibling Pruning: Intelligently removes XML nodes that are not visible on the screen based on OCR analysis or manual text input.
• Flexible Text Input: Optionally provide visible text manually, or use OCR for automatic extraction.
• Dual OCR Strategy: Choose between EasyOCR (Deep Learning based, high accuracy) or Tesseract (Fast, standard) as fallback when manual text is not provided.
• Comprehensive Visualization:
  • Tree View: See the hierarchical structure of your XML before and after cleaning.
  • Screen View: Visual confirmation of bounding boxes overlaid on the original screenshot.

How to use

1. Upload the Screenshot of the app state.
2. Upload the corresponding XML dump (from uiautomator).
3. (Optional) Enter visible text from the screenshot manually (one per line or comma-separated). If left empty, OCR will be used automatically.
4. Select your preferred OCR engine (only used if visible text is not provided).
5. Click Process.
6. View the comparisons in the tabs and download the cleaned XML.

Technical Details

This application uses a sophisticated pipeline:

1. Text Extraction: Uses provided visible text (if available) or extracts visible text from the image using OCR.
2. LCA Calculation: Finds the Lowest Common Ancestor of all active elements.
3. Pruning: Traverses upward from the Active LCA and prunes siblings that contain no visible text.
