I am trying to insert some text after every paragraph in my content.
I explode my content by </p> It is done using following code:
$Paragraphs = explode( '</p>', $Content); foreach($Paragraphs as $Paragraph){ // Some code }Now my $Content looks like:
<p></p><p></p><p></p><div><p></p></div><p></p><p></p><div><p></p></div>I want to split if <p> isn’t wrapped inside <div> or <table> of anything else.
You can say that the </p> should have a <p> after it.
I read Regex can be helpful in achieveing it.
Here’s the basic regex I built:
$Pattern = '/<p(|s+[^>]*)>(.*?)</ps*>/';if(preg_match_all($Pattern, $Content, $keywords)){}This regex currently removes the
itself from the array, it keeps content inside p but not the
itself, and it doesn’t check for it being either having a
before it orafter it.

If i understood your problem you have a string with tags such as:
$string = "<p> Sometext 1 </p><p> Sometext 2 </p><p> Sometext 3 </p><div><p> Sometext Inside A Div </p> </div>";And you want to add another element right after each p that is not contained in any other element. And you want to do that purely through PHP, correct ?
In my opinion your best option is using DOMDocument.
Take a look at the solution below:
$doc = new DOMDocument();$doc->loadHTML($string);foreach ($doc->getElementsByTagName('p') as $idx => $item) { if($item->parentNode->nodeName == 'body') { $fragment = $doc->createDocumentFragment(); $fragment->appendXML('<div> <div> <img src="image.jpg"/> </div> </div>'); $item->parentNode->insertBefore($fragment, $item->nextSibling); }} echo $doc->saveHTML();Basically i am taking your string converting it into an HTML DOM then i iterate through all the p elements and if their parent is body then i create a document fragment which will append XML raw data to create your deeply nested structure without creating each element individually. Finnaly i insert the newly create fragment after each iterated p element.
The output will look something like this:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"><html> <body> <p> Sometext 1 </p> <div> <div> <img src="image.jpg"> </div> </div> <p> Sometext 2 </p> <div> <div> <img src="image.jpg"> </div> </div> <p> Sometext 3 </p> <div> <div> <img src="image.jpg"> </div> </div> <div> <p> Sometext Inside A Div </p> </div> </body></html>
