Thanks for the note @Thiago. I changed the demo file so that it wouldn't point to the missing page anymore.
Hello Ned Gulley, thanks for sharing.
Your documentation is still using a page that does not exist anymore. A nice suggestion is:
the_url = 'http://www.mathworks.com/matlabcentral/fileexchange/44751-url-filter';
total_widgets = urlfilter(the_url,'Downloads', 1, 'backward');
This scraps the number of downloads of your file automatically.
Very useful. And it does indeed support numbers with comma separated blocks!
Hi @nickname: It's not a VBA macro. All the code is right here in this repo.
hello,
in regards to your vba macro at http://blogs.mathworks.com/pick/2014/01/17/scraping-data-from-the-web/ , can i please have the complete code for this to work. Please Email eseibel2010@gmail.com Thank you
Hi Oliver. Thanks for the note. That should already work. If it doesn't, let me know.
Very useful. It would be great if it supported numbers which have commas separating blocks of digits, e.g. 73,090,906 (around 73 million).
@Beaver: Google does a pretty thorough job of blocking programmatic scraping. I'm not sure you'll be able to get that to work.
