Custom extraction · CSS selector evidence

Extract page text and attributes with CSS selectors

Collect repeated headings, prices, labels, links, identifiers, and other source values from one public HTML page. Each selector keeps its match count, empty or missing values, source order, validation state, and export limits visible.

Ready for a page and your selectors.

No sample values, extraction grade, or manufactured matches are shown. Results begin with the bounded live response.

Build selectors you can maintain

Prefer stable structure and explicit source fields

Extract repeated content

Use selectors tied to meaningful element names, durable classes, or attributes. Layout-position selectors can become brittle when templates change.

Keep missing values visible

A matched element and a populated attribute are different observations. Missing and empty counts stay separate from the retained values.

Validate on representative pages

One source page cannot prove a template is consistent across a site. Export the rule evidence and repeat it against relevant page types.
