Scrape information from meta data with Javascript

Question

I wonder how I can scrape how I can scrape of author affiliation from a page like this:

http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=1701938

The information that I want is stored in a meta-tag that looks like this:

<meta name="citation_author_institution" content="Department of Computing Science, University of Alberta"> 

I tried something like this:

var affiliation = doc.getElementsByTagName('meta').item(property='citation_author_institution');

But this didn't seem to work for me. Can someone enlighten please

Answer 1

Thx to the user Reeno, I finally got the content of this meta tag that I needed. Here is the final code:

var affiliation = doc.getElementsByTagName('meta')[property='citation_author_institution'].content;
