Parser

Parser

Extract structured product data from raw HTML. Tries JSON-LD first via Extruct, falls back to CSS selectors via Parsel.

When to use

Use this skill when you have raw HTML and need to extract structured data from it — product details, prices, specs, ratings, or any page content.

Instructions

1. Save the HTML to a temporary file page.html
2. Run parser.py against it:

   python parser.py page.html
   

3. The script outputs a JSON object. Check the method field:
   • "extruct" — clean structured data was found, use it directly
   • "parsel" — fell back to CSS selectors, review fields for completeness
4. If key fields are missing from the Parsel output, ask the user which fields they need and re-run with --fields:

   python parser.py page.html --fields "price,rating,brand"
   

5. Return the parsed JSON to the conversation for use in the Compare skill.

Notes

• Always prefer the Extruct path — it is more stable and requires no maintenance
• Parsel selectors are generated heuristically and may need adjustment for unusual page layouts
• Run once per page; pass all outputs together into the Compare skill
