schemaorg_rs::extraction

Struct RdfaLiteExtractor

pub struct RdfaLiteExtractor;

Expand description

Extracts Schema.org structured data from RDFa Lite 1.1 attributes.

§Examples

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

let html = r#"<html><body>
<div vocab="https://schema.org/" typeof="Product">
<span property="name">Widget</span>
</div>
</body></html>"#;

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

Implementations§

impl RdfaLiteExtractor

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.
