MicrodataExtractor

schemaorg_rs::extraction

Struct MicrodataExtractor

pub struct MicrodataExtractor;

Expand description

Extracts Schema.org structured data from HTML Microdata attributes.

§Examples

use schemaorg_rs::extraction::{Extractor, MicrodataExtractor};

let html = r#"<html><body>
<div itemscope itemtype="https://schema.org/Product">
<span itemprop="name">Widget</span>
</div>
</body></html>"#;

let output = MicrodataExtractor.extract(html).unwrap();
assert_eq!(output.nodes[0].types, vec!["Product"]);

Implementations§

impl MicrodataExtractor

pub fn extract_from_document( &self, document: &Html, ) -> Result<ExtractionOutput, ExtractionError>

Extracts from an already-parsed document.

§Errors

Returns ExtractionError if a fatal error prevents extraction. Most issues are captured as warnings in the returned output.

§Panics

Panics if the internal CSS selector constant fails to parse. This is a compile-time-verified string and will never fail.
