Parse a stream of HTML using CSS selectors to extract data. Doesn't require a DOM, thus it's fast and low-memory.
Define your scraping parameters in a JSON manifest:
rem.stream("http://news.ycombinator.com/").pipe(skim({
"$query": "td.title ~ td ~ td.title > a",
"$each": {
"title": "(text)",
"link": "(attr href)"
}
}, function (err, json) {
console.log(json);
});
Result:
