Hi,

I need to import some FX rates from the following website:

http://www.federalreserve.gov/releases/h10/hist/dat00_eu.htm

The table is located within this webpage and gets updated daily.

Does anyone know how to code the import of the whole table from this website into Matlab into my workspace?

Thanks

Sorry but I'm confused by your reply.

Can you explain your suggestion please?

Poke around the links on the Fed site a little and explore their setup explicitly for distributing data instead of just trying to rip the web page. There's an "RSS" button at the top of the page you've linked to and more on data if follow the links...

Hi,

using urlread should do it. Pretty rough code but it gets it done:

html= urlread('http://www.federalreserve.gov/releases/h10/hist/dat00_eu.htm');
txt = regexprep(html,'<[^>]*>','');
starts_at = strfind(txt,'Rate');
ends_at = strfind(txt,'Last update:');
txt = txt(starts_at(end)+4:ends_at-1);
tmp = textscan(txt,'%s','delimiter','\n');
idx=cellfun(@isempty,tmp{1});
tmp = strtrim(tmp{1}(~idx));
date = tmp(1:2:end);
value = tmp(2:2:end);
