Answer 1

Test your response before running the regex search. Then you'll know which part isn't working.

Answer 2

You want to parse a multiline content but you did not use multiline switch of REGEX pattern. Try using this:

preg_match_all('#<div id="myLocContainer">(.*?)</div>#sim', $page_all, $div_array);

Please note that regular expressions is not suitable for parsing HTML content because of the hierachical nature of HTML documents.

Answer 3

try adding "m" and "s" modifiers, new lines might be in the div you need.. like this:

preg_match_all('#<div id="myLocContainer">(.*)</div>#ms', $page_all, $div_array);

Answer 4

Before messing around with REGEX, try HTML Scraping. This http://stackoverflow.com/questions/34120/html-scraping-in-php might give some ideas on how to do it in a more elegant and (possibly) faster way.

Answer 5

$doc = new DomDocument;
$doc->Load('http://weather.yahoo.com/');
$doc->getElementById('myLocContainer');

Answer 6

you need to Excape Special Characters in your Regular Expression like the following

~\<div id\=\"myLocContainer\"\>(.*)\<\/div\>~

also Checkout wheather there is a newline problem or not as mentioned by @eyazici and @kgb
