PHP DOM find div class and output html inside div
Solution 1:
I would approach the issue by using xpath to select the target element, convert it to string and then use string manipulation methods to get to the desired output. It's a bit convoluted, but the code below should work for both html strings (the one in your question and the one in your comment); however, depending on the html structure, may have to be modified:
$html1 = <<<HTML
<div class="test1">Test1<div class="test2"></div>Some Text</div>
HTML;
$html2 = <<<HTML
<div class="xx1">Some Extra Test<div class="test1">Test1<div class="test2"></div>Some Text</div></div>
HTML;
$doc = new DOMDocument;
$doc->loadhtml($html2); //or html1
$xpath = new DOMXPath($doc);
#get the right element using xpath
$node= $xpath->query('//div[@class="test1"]');
#convert the element to string
$target = $node[0]->ownerDocument->saveHTML($node[0]);
#now manipulate the string; it can be done in one step, but I broke it into two for clarity
$step1=explode('class="test1">',$target);
$step2 = explode('</div>',$step1[1]);
echo implode("", $step2);
Output in either case:
Test1<div class="test2">Some Text
Solution 2:
You can not use createTextNode because by definition this is only text and will not contain HTML tags.
The correct approach should be:
- You loop all the
childrenof your$node. So in your case you have 3 children:
- The text element
Test1 - The HTML tag
<div class="test2"></div> - The text element
Some Text
- For each of these children, you move them up 1 level: from being contained within your
$node, to being attached to its parent. To do so, youclonethe node, then youinsertBeforeto the$prent - You remove the initial
$node
In code:
foreach ($nodes as $node) {
$prent = $node->parentNode;
foreach ($node->childNodes as $childNode) {
$prent->insertBefore($childNode->cloneNode(true), $node);
}
$prent->removeChild($node);
}
This will output, as requested
Test1<div class="test2"></div>Some Text
