I need to have the data that are "behind" the link - is there any way to do this with a easy and understandable parser - one that can be understood and written by a newbie??

Answer 1

Your provided links are down, I will suggest you to use the native PHP " DOM " Extension instead of "simple html parser", it will be much faster and easier;) I had a look at the page using googlecache, you can use something like:-

$doc = new DOMDocument;
@$doc->loadHTMLFile('...URL....'); // Using the @ operator to hide parse errors
$contents = $doc->getElementById('content')->nodeValue; // Text contents of #content

Answer 2

Seems to be written in the documentation :

$html1->find('b[class=info]',0)->innertext;

Answer 3

From what i can quickly glance you need to loop through the <dl> tags in #content, then the dt and dd.

foreach ($html->find('#content dl') as $item) {
     $info = $item->find('dd');
     foreach ($info as $info_item) {..}
}

Using the simple_html_dom library

Answer 4

XPath makes scraping ridiculously easy, and allows for some changes in the HTML document to not affect you. For example, to pull out the names, you'd use a query that looks like:

//div[id='content']/d1/dt

A simple Google search will give you plenty of tutorials

Answer 5
