I'm looking to parse through some HTML source code to pull information from the Wall Street Journal. I need to pull the price of the following commodities: the 4 domestic crude oil spot prices, copper, aluminum, cotton, and cocoa
I'm having some trouble with getting regexp to work the way I want it to.
what string expression would you use to pull out the middle (bold) price listed? If the value is n.a., it's okay if it just returns 'n.a.' or its equivalent.
I tried a variety of methods and I couldn't get it to work.
Could someone show an example of the string he or she would use for extracting the price?
