How to get content from external websites by class name

I am trying to get the contents from span, class, div from external other domain to my personal website by class name For example:

I need to a table from external website that has a class called .table that to Be updated once per minute, how to Import it in my website automatically the table hasn't API and XML ,RSS just it is a simple html website .

 

You need to use something in the back end like a html scraper. http://simplehtmldom.sourceforge.net/

 

use any programming language to grab the source code of the page and then use Dom Parser to get the content of a div
search for a "Dom parser" and you will get exactly what you looking for : )

 

Dear friend tnx a lot which source code for PHP is better to grab content Do you think?

I hear curl libraries or file_get content is most common methods ,that's True .

 

use php-curl to get source code, then use querypath to parse
