Question

source code:

<div id="point">9</div>
<div id="point">REAL POINT: 9</div>

and parser code:

$point = $html->find('div[id=point]');

so, when you write $point[0] it will be first, and the other will be second.

But sometimes i need to make an algorithm like this: “find the divs with id point and must begin with REAL POINT: “

We can find

$point = $html->find('div[id=point]')->innertext=' REAL POINT:';

But that finds only divs include ‘ REAL POINT:’

But i have to find divs innertext begin ‘REAL POINT:’

How can i find?

Answer 1

You could use stripos for case sensitive.

foreach($html->find('div[id=point]') as $element) {
    if ( strpos($element->innertext, 'REAL POINT:') !== FALSE ) {
        // something here
    }
}

You could also do a search for the string exactly at the start:

foreach($html->find('div[id=point]') as $element) {
    if ( strpos($element->innertext, 'REAL POINT:') === 0 ) {
        // something here
    }
}

But if you want to remove whitespace before the first character in a div:

foreach($html->find('div[id=point]') as $element) {
    if ( strpos(trim($element->innertext), 'REAL POINT:') === 0 ) {
        // something here
    }
}
