python - How to parse a HTML page including hidden tags

I'm trying to parse some web pages for future use. For parsing webpages, I've used different modules like urllib, lxml, BeautifulSoup, HTMLParser to reach my goal.

I didn't meet any problem while parsing web pages until I faced the hidden tags.

When I opened the page with a chrome browser and used the developer tools to see elements of page, I was able to see the <embed> part of the code:

 <embed type="..." src="..." ID="..." >

and simply can copy/paste manually.

I need to parse ID from this hidden tag. Why can I parse this part from the site by using python? Any way to parse these hidden parts?

I know it's not possible to see some code parts like php and asp in the html source but I suppose it's not the case.

This "hidden" code is probably generated by JavaScript at runtime.

You might have better luck finding out how the JavaScript works and where it gets its data (the URLs) than attempting to have something run the script and then parse the resulting DOM tree...
