Simply read the webpage as text file and parse it as mentioned here

Thanks for the reply,
based on what u proposed I can read the page. How can I use a particular number among other irrelevant information? (it reads like 100 lines but I only need to use a number within that text)

Find the line in which the required information is available.

Parse the text using string functions and extract the data.
