Extracting data from a web page

Hi Jorge,

You can use Matlab's web scraping capabilities along with regular expressions to extract the desired numerical data. Here is a sample code snippet that demonstrates how to extract the Moment value from the provided webpage:

% URL of the webpage

url = 'https://earthquake.usgs.gov/earthquakes/eventpage/us7000e7y0/executive';

% Read the webpage content

webpage = webread(url);

% Extract Moment value using regular expressions

moment_pattern = 'Moment:(\d+\.\d+e[+-]\d+) N-m';

moment_match = regexp(webpage, moment_pattern, 'tokens', 'once');

% Display the extracted Moment value

if ~isempty(moment_match)

    moment_value = str2double(moment_match{1});

    disp(['Extracted Moment Value: ', num2str(moment_value)]);

else

    disp('Moment value not found.');

end

Hope that answers your question.
