Question

I am learning scraping using the PHP Simple HTML DOM Parser and Xpath. Accroding to the changelog given here http://sourceforge.net/news/?group_id=218559. The PHP SImple HTM

Answer 1

The find function. http://simplehtmldom.sourceforge.net/manual.htm#section_find

$content = file_get_html($link);

$elems = $content->find("/html/body/div/div");

Answer 2

There's find function in Simple HTML DOM Parser. BUT it accepts selectors! So you cant just write

$html = file_get_html($link);
$elements = $html->find("/html/body/div/p");

because then you'll get more than one element!

to get just exact element marked by XPath, write

$element = $html->find("/html/body/div[1]/p[1]", 0);
