I'm looking for an effective way to parse html content in node.JS.The objective is to extract data from inside the html, not handle objects.It is a server-side thing.I tried using jsdom and I found two major issues:Massive memory usage (probably some memory leak)Won't parse properly if the code is a malformed html.So I'm considering using regex to seek inside html streams.In the code bellow I slim down the html stream removing extras spaces and new lines so the regex will cost less to match:html = html.replace(/\r?\n|\s{2,}/g,' ');console.log(html.match(/<my regex>/));I also thought of putting it on a function that would narrowing down even more by getting only the part of the html that matters like:<html> <!-- a lot of irrelevant code --><table id=fooTable>   </table><!-- a lot of irrelevant code --></html> This would narrow down the code to cost even less to apply the regex match:var i = html.indexOf('fooTable');var chunck = html.substring(i); Please have your say.Would regex be an elegant/effective way to parse large html content? Is it cpu expensive to run a regex on a very large string?
