rdfxmlprocessor

RDF/XML parser

This library processes RDF/XML from an XML DOM. It returns RDFJS compliant triples.

Use

Install it through NPM:

npm i rdfxmlprocessor

Then use it in your code as follows:

const RDFXMLProcessor = require('rdfxmlprocessor');
const {DataFactory} = require('n3');
const {DOMParser} = require('xmldom'); //Or just DOMParser in the browser
 
//You can choose your own data factory (useful if, among others, you’re using different RDFJS compliant parsers and they each parse blanknodes).
var parser = new RDFXMLProcessor(DataFactory);
try {
    parser.parse(new DOMParser().parseFromString(`<?xml version="1.0"?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
         xmlns:dc="http://purl.org/dc/elements/1.1/"

  </rdf:Description>
  </rdf:RDF>`), 'http://example.org/baseuri/', 'http://example.org/graphname', function (triple) {
    if (triple)
      console.log(triple);
});
} catch (e) {
    console.trace(e);
}

You can also use it in your browserify or webpack projects.

Tests

You need to have mocha installed globally (npm i -g mocha).

Limitations

As it relies on a DOM tree, the size of the XML document to be read is limited to the size of your memory.
