What i am trying to do is to edit multiple html pages with a php script. However what i do not know is how to implement Regex to do what i need.

i have a javascript code that replaced a tag="such and such" to onclick="tag'such and such';" however find and replace only replaced the first part leaving the following:

onclick="tag'such and such"

i need to parse the DOM and add '; before the "

onclick="tag'(.*?)" search finds even those that do not require changes due to the generality of the (.*?) command.

how can i find all the ones that do not have '; and replace with preg_replace .


Assistance highly appreciated
