Question

I have a few <li> tags inside a <div> like this:

<li> <a href="link1"> one <li>
<li> <a href="link2"> two <li>
<li> <a href="link3"> three <li>

How can I get the text two using HTML DOM parser and then put it inside an array to use later?

Answer 1

You need to make sure the a tag is closed then you can do it like this:

<?php 
$html = '<li> <a href="link1"> one </a> <li>
<li> <a href="link2"> two </a> <li>
<li> <a href="link3"> three </a> <li>
';

// Create a new DOM Document
$xml = new DOMDocument();

// Load the html contents into the DOM
$xml->loadHTML($html);

// Empty array to hold all links to return
$result = array();

//Loop through each <li> tag in the dom
foreach($xml->getElementsByTagName('li') as $li) {
    //Loop through each <a> tag within the li, then extract the node value
    foreach($li->getElementsByTagName('a') as $links){
        $result[] = $links->nodeValue;
    }
}
//Return the links
print_r($result);
/*
Array
(
    [0] =>  one 
    [1] =>  two 
    [2] =>  three 
)

*/
?>

Its all in the manual for domDocument
