How to parse and process HTML with PHP?

Is there any special syntax to get nested div element with unique class name in RegExp in php. Consider I have a syntax like

<div style="demo">
<div class="row">
    <div title="abc@examples.com" class="text">ABC</div>
</div>
<div class="row">
    <div title="pqr@examples.com" class="text">PQR</div>
</div></div>

here how can we retrieve all emailids using RegExp and preg_match_all().

---

preg_match_all("/<div title="(.*)" class="text">/", $subject, $matches);

If the emails is the only data you want there are better regexps for matching emails only. See http://fightingforalostcause.net/misc/2006/compare-email-regex.php

Regex are bad at parsing HTML. Use a DOM Parser and this XPath:

//div[@style="demo"]/div[@class="row"]/div[@class="text"]/@title

If class="text" is exclusive to the divs you want to match, you can also do

//div[@class="text"]/@title

Also see:

https://stackoverflow.com/search?q=html+dom+php

<?php

$html = '<div style="demo">
<div class="row">
    <div title="abc@examples.com" class="text">ABC</div>
</div>
<div class="row">
    <div title="pqr@examples.com" class="text">PQR</div>
</div></div>
';

$doc = DOMDocument::loadHTML($html);
$xpath = new DOMXPath($doc);

foreach($xpath->query('//div[@style="demo"]/div[@class="row"]/div[@class="text"]/@title') as $div){
    echo $div->value . PHP_EOL;
}

这假设类的属性完全是那些（逐字），但我希望你明白这一点。
