You need to write a regular expression that could get any link from this tag:

meta property = "og: image" content = "https://scontent-fra3-1.cdninstagram.com/t51.2885-15/e35/14276400_1742191619336501_90536135_n.jpg?ig_cache_key=MTMzMjc1MzEzNjkzMDQzMTEyNQ%3D%3D.2" />

Closed due to the fact that the essence of the issue is not clear to the participants of Kromster , Denis , Harry , pavel , Denis Bubnov Jan 17 '17 at 13:00 .

Try to write more detailed questions. To get an answer, explain what exactly you see the problem, how to reproduce it, what you want to get as a result, etc. Give an example that clearly demonstrates the problem. If the question can be reformulated according to the rules set out in the certificate , edit it .
