When I tried with Evernote clipper extension, I see a very useful feature. When I clicked at "article", It gives me a really correct main content of page. Let see the result when I used Evernote Clipper with page https://developer.chrome.com/extensions/api_index

I looked at the main article that evernote field out, in several pages, the article is infact extracted from the first article tag. However evernote clipper still work well with pages doesn't use that kind of tag.

I wonder how Evernote clipper can do that ? Is there any js library support to detect the main tag containing the main content of pages. Could you give me some advises to do it.

Thank you in advance!

解决方案

From my knowledge, there is no universal js lib to do that. The Evernote clipper uses its own method to extract the "interesting" content from a web page. You can access the code of the Evernote clipper to try to understand the process.

On my mac, the path to the chrome extension is :

~/Library/Application Support/Google/Chrome/Default/Extensions/pioclpoplcdbaefihamjohnefbikjilc/6.2_0/

Here's another tool that works pretty much the same : https://www.readability.com/

or search on google for terms like 'content extraction js lib' for example. (Found this one : https://github.com/hatena/extract-content-javascript)
