PHP cut text from a specific word in an HTML string - php

Question

I would like to cut every text ( image alt included ) in an HTML string form a specific word.
for example this is the string:
<?php
$string = '<div><img src="img.jpg" alt="cut this text form here" />cut this text form here</div>';
?>
and this is what I would like to output
<div>
<a href="#">
<img src="img.jpg" alt="cut this text" />
cut this text
</a>
</div>
The $string is actually an element of an Object but I didn't wanted to put too long code here.
Obviously I can't use explode because that would kill the HTML markup.
And also str_replace or substr is out because the length before or after the word where it needs to be cut is not constant.
So what can I do to achive this?

Answer 1

Ok I solved my problem and I only post an answer to my question because it could help someone.
so this is what I did:
<?php
$string = '<div><img src="img.jpg" alt="cut this text form here" />cut this text form here</div>';
$txt_only = strip_tags($string);
$explode = explode(' from', $txt_only);
$find_txt = array(' from', $explode[1]);
$new_str = str_replace($find_txt, '', $string);
echo $new_str;
?>
This might not be the best solution but it was quick and did not involve DOM Parse.
If anybody wants to try this make sure that your href or src or any ather attribute what needs to be untouched doesn't have any of the chars in the same way and order as in $find_txt else it will replace those too.
