Hi,  
I want to remove the onclick event from my html tag. For instance, given the following:

\<input type=“text” name=“txtEmail” id=“txtEmail” onclick=“parent.showTestStrategyDiv(this.id, this.name);” /\>

‘onclick’ will be removed and the new string will look like this:

\<input type=“text” name=“txtEmail” id=“txtEmail” /\>

To do this, I call the preg\_replace method in php:

$alteredContent3 = preg\_replace("#(\<input.+?)(on[Cc]lick.+?)(/?\>)#i", “\1\3”, $alterContent2);

Given that alterContent2 is the the html page which I want to alter. Somehow, when I tried to print out the values for $alteredContent3, nothing is returned. Any help is greatly appreciated. Thanks in advance.
