Find and replace string in HTML using PHP DOM Parser

How do you find and replace a string in html page using the native PHP DOM Parser?

Example string to find: "the <a href='site.com'>company</a> has been growing for the past 5 months";

The parent is a full HTML page for example and the immediate predecessor of that string can be a <div> or <p> for example..

There is no id or class to that element. Is it still possible to find and manipulate it ?

There is nothing to identify the string or its immediate predecessor. Only the exact string, i.e. sequence of characters that the $search_string consists of.

Thanks!

EDIT:

$string_to_replace = "the <a href='site.com'>company</a> has been growing for the past 5 months";

$replacement_string = "<span class='someClass'>the <a href='site.com'>company</a> has been growing for the past 5 months";</span>

Since this seems to span part of a node with child nodes, I would use a replace like this:

// Text in $html
$find  = "the <a href='site.com'>company</a> has been growing for the past 5 months";
$find_len = strlen( $find );
$start = strpos( $html, $find );
if ( $start !== false ) {
    $html = substr( $html, 0, $start )
        . '<span class="someClass">' . $find . '</span>'
        . substr( $html, $start + $find_len );
}

I do not have time to test it properly, but it might point you in the right direction.

PHP DOM would be excellent to change the href attribute of element a or it's contents (company). It should also work if $find is the full contents of a <div>-element
