You will need to break apart the entire document then process each area inside of the tags and to be very careful for nested tags.
The simplest way around I have found to do with is to add to tags that have been processed with attributes that are ignored by the browser renderer eg... <a href="/page.html" done="yes">PHP</a> as you can see the <a href has been processed because I have added in a extra attribute then continue to process the entire page from my preg matches. Nested tags are going to be your biggest issue.
