I want to validate some HTML documents in a node.js application. I already found some node.js modules like w3cjs and w3c-validate, but it seems that they are only working online. Because I have to check many small HTML documents, I'm searching for a solution that works offline, without internet.
Do you know how to integrate the W3C Markup Validator in a node application? Or what are other ways to check HTML syntax? Maybe something like a DOM parser?
