Is it possible to get the html source code of a webpage with curl and the run a javascript interpreter over it, so i get the generated content?

The Page i need to get uses some encoded and genereated content in there so i want to first run the javascript to get the escaped and generated content... or do i need to regex the javascript and "compile" the javascript on my own? Like

curl <myurl> | perl -ne 'm/unescape\((.*)\)/; print "$1"' | <now to something with that>

i known there is no javascript engine in curl but can i just call another script / programm to do the job?

You can do it, but it's more involved than I think you realize. Neither curl nor wget have Javascript engines, so you'll need something that has one.

I would start by looking at PhantomJS and/or Chromium Headless.

  • nice, i didnt knew that there where such things :) I will also update my screenshot script which currently goes over some edges then using phantomjs! – reox May 10 '12 at 08:52
  • PhantomJS has been suspended as of March 2018. I'd love to know of a more up-to-date option. Depending on the use, there might be security issues with using an unmaintained package. – cazort Jun 05 '22 at 15:37
