Webapp: How to read a value from a table

when I activate search for , say, crude oil price , I get a table as below:

I want to read only the price of Arab Light.

Next, if I search for Brent Crude Price, I get the same table showing Brent price in different row.
Here I want to read only Brent Price.

How to achieve this?



Kindly refer this post

Thanks Amit, I will try this as a first step.
However, eventually, I would like to extract only those values which the user wants.
For example, if user wants price of “Brent Crude”, then only Brent Crude price needs to be extracted.
Could you suggest a better way for this?
