Question

I’m on a strict time limit and I really need a regex to parse this type of anchor (they’re all in this format)

<a href="20120620_0512_c2_1024.jpg">20120620_0512_c2_102..&gt;</a>

for the URL

20120620_0512_c2_1024.jpg

I know its not a full URL, it’s relative, please help

Here’s my code so far

year = datestr(now,'yyyy');
timestamp = datestr(now,'yyyymmdd');
html = urlread(['http://sohowww.nascom.nasa.gov//data/REPROCESSING/Completed/' year '/c2/' timestamp '/']);
links = regexprep(html, '<a href=.*?>', '');

Answer 1

Try the following:

url = 'http://sohowww.nascom.nasa.gov/data/REPROCESSING/Completed/2012/c2/20120620/';
html = urlread(url);
t = regexp(html, '<a href="([^"]*\.jpg)">', 'tokens');
t = [t{:}]'

The resulting cell array (truncated):

t = 
    '20120620_0512_c2_1024.jpg'
    '20120620_0512_c2_512.jpg'
    ...
    '20120620_2200_c2_1024.jpg'
    '20120620_2200_c2_512.jpg'
