php - Get all text inside html tag with regex? -

for example, have html:

<strong>this one</strong> <span>test one</span> <strong>this two</strong> <span>test two</span> <strong>this three</strong> <span>test three</span> 

how text inside strong , span regex?

use dom , never use regular expressions parsing html.

$dom = new domdocument; $dom->loadhtml($html); foreach ($dom->getelementsbytagname('strong') $tag) {    echo $tag->nodevalue."<br>";   } foreach ($dom->getelementsbytagname('span') $tag) {     echo $tag->nodevalue."<br>"; } 

output :

this 1 2 3 test 1 test 2 test 3

why shoudn't use regular expressions parse html content ?

html not regular language , hence cannot parsed regular expressions. regex queries not equipped break down html meaningful parts. many times not getting me. enhanced irregular regular expressions used perl not task of parsing html.
