Replacing String Outside HTML Tags

[jessjenn]

Is there a way to replace strings (text) outside HTML tags? I'm trying to accept a block of HTML content (could include CSS/JavaScript) and be able to replace several words or characters only outside HTML tags. So for example I would be able to accept this:

 	<h4>
 		<a href="/article/domains-launched-icann">New Top Level Domains Launched by ICANN</a><br />
     <span class="credit">by Derek&nbsp;Vaughan - Apr 3rd, 2004</span>
		   </h4>
<div class="art">
  <a href="/article/domains-launched-icann"><img src="http://www.SitePoint.com/graphics/author_derek.jpg" width="56" height="67" alt="Derek&nbsp;Vaughan" /></a>

<p>[b]ICANN[/b] recently released the details of 9 new TLD proposals. The proposals come from all corners of the globe, and all areas of commerce. [b]Derek[/b] outlines each in detail, and preempts the potential for an [b]Internet[/b] land-grab when the approved names become official...</p>

And change it to...

Thanks!

It's entirely possible, but opens up a lot of security issues. If I were to do this, I might have the script chmod() them to a tighter security setting after replacing the text

since i am not in my desk i can give u the logic

1. open the file (fopen,fread)

2. check if yourtextlookingfor==textofthefilethatyourlooking
   if found then ereg_replace()

3. Save the content of your file in a variable
   yourvaribale.=the content of your html

4. close the file (fclose)

5. open again the file (fopen)

6. now write the file (fwrite(yourvariable))
