Dynamic page crawling, parsing questions.

Hello.

I'm going to make a web crawler or parser.

Python, php, Java, and so on.

http://ces17.mapyourshow.com/7_0/floorplan/index.cfm?hallID=F&selectedBooth=booth~1233

Whenever I go into the above site and click on the booth, There are booth information on the right, and I'm going to scratch the text. The problem is that I've tried many different ways, <h1> I found and inserted a place with the class name "sc-Exhibitor_Name" in the tag, but it does not apply.

What should I do? ㅠ<
