----------------------------------------
To now, I make code is import string.
--------------------------------------------------------------------
url = 'http://www.kma.go.kr/wid/queryDFSRSS.jsp?zone=4146357000' ;
data = webread (url);
data(strfind(data, '>')) = [];
Key_1   = '<temp';
Index_1 = strfind(data, Key_1);
Value_1 = sscanf(data(Index_1(1) + length(Key_1):end), '%g', 1);
---------------------------------------------------------------------

value_1 = 13.1

But this data is changed three-hourly automatically.

So I want to make code that import value three-hourly automatically.

Please help me.

Answer 1

I recommend you leave the '>' in place, and that you use regexp() to find the information you need.

To import every three hours, use a timer() function.
