Fetching dynamically loaded content

[balmy raft]

Hello!

I am attempting to fetch the data from a dynamically loaded page, but the data is in an odd/compresed format. How can I inflate the data to actually get the text contained within it? Here is the link to the data: https://web.pulsepoint.org/DB/giba.php?agency_id=EMS1209
TYIA!

For reference, I am hoping to utilize the text to iterate through a simple for loop checking for certain addresses.
