Reading tags

Is there a way to do this (with credentials) from a website.
Honeywell has a website for some data I want to get at, but you have to login with credentials.
Once logged in you have the options to download csv,txt, or xml. I also have to ‘choose account’ from
a drop down that is not defaulted to my account.
Which would be easier to parse and is it possible to login with credentials via scripting and make the necessary account choices just to finally arrive at the file download?
I do have the credentials, and Ignition 7.5. Also have a MSSQL database where I can write the tags to.

Also, on the same page where the downloads are, exists a display of the values.
I am thinking once logged in where the data is being displayed I could just parse it from there…
This may be the best option since wsdl type service is not available at this time
Help appreciated…
more precisely examples of logging in with credentials through scripting, appreciated
