Replace text with altering HTML

[texelate]

Hi

I'd like to perform a str_replace on some HTML but I don't want any of the HTML tages to be affected.  For example if the original string has:

[code]$html = '<div><img src="/a_picture_of_me.jpg" alt="" /> A picture of me</div>';[/code]

And I do a str_replace to change "picture" to "Jon" I will end up with:

[code]$html = '<div><img src="/a_picture_of_Jon.jpg" alt="" /> A picture of Jon</div>';[/code]

Is there any way I can replace it without affecting any HTML tags - so I'd end up with:

[code]$html = '<div><img src="/a_picture_of_me.jpg" alt="" /> A picture of Jon</div>';[/code]

Thanks in advance.

If the word "me" is always followed by a < tag, then you could do like this:

[code=php:0]echo preg_replace('/\bme\b(?=<)/s', 'Jon', $html);[/code]
