First i have to tell you that you can't use the same id on two different divs; there are classes for that point. Every element should have an unique id.
Code to get the contents of the div with id="interestingbox"
$html = '
<html>
<head></head>
<body>
<div id="interestingbox">
<div id="interestingdetails" class="txtnormal">
<div>Content1</div>
<div>Content2</div>
</div>
</div>
<div id="interestingbox2"><a href="#">a link</a></div>
</body>
</html>';
$dom_document = new DOMDocument();
$dom_document->loadHTML($html);
//use DOMXpath to navigate the html with the DOM
$dom_xpath = new DOMXpath($dom_document);
// if you want to get the div with id=interestingbox
$elements = $dom_xpath->query("*/div[@id='interestingbox']");
if (!is_null($elements)) {
foreach ($elements as $element) {
echo "
[". $element->nodeName. "]";
$nodes = $element->childNodes;
foreach ($nodes as $node) {
echo $node->nodeValue. "
";
}
}
}
//OUTPUT
[div] {
Content1
Content2
}
Example with classes:
$html = '
<html>
<head></head>
<body>
<div class="interestingbox">
<div id="interestingdetails" class="txtnormal">
<div>Content1</div>
<div>Content2</div>
</div>
</div>
<div class="interestingbox"><a href="#">a link</a></div>
</body>
</html>';
//the same as before.. just change the xpath
[...]
$elements = $dom_xpath->query("*/div[@class='interestingbox']");
[...]
//OUTPUT
[div] {
Content1
Content2
}
[div] {
a link
}
