Retreive data from a website

Hi, I am looking for a way to retreave multiple data from a website and store them in array in an effecient way, this is my code:

% Get the html for the webpage
html = webread("https://www.digikey.com/products/en/fans-thermal-management/thermal-heat-sinks/219");

% find the start and end of the data and remove the rest
iStart = strfind(html, "Thermal Resistance @ Forced Air Flow");
iStart = iStart(1);

iEnd = strfind(html, "Thermal Resistance @ Natural");
iEnd = iEnd(1);

html = html(iStart:iEnd);

% get the indexes of the start and finish of the data points
iStart = strfind(html, "<option value") +23;
iEnd = strfind(html, "</option")-1;

% pre-allocate results
results = strings(numel(iStart), 1);

% write and clean up results
for i = 1:numel(results)
    
    results(i) = string(html(iStart(i):iEnd(i)));
    results(i) = strrep(results(i), " ", "");
    results(i) = strip(results(i));
    
end 

Is there a better and simpler solution then this one ?

I suggest you use regexp() with "named" tokens.
