I did a regular expression search and replace and it's suppose to be completed but I found a flaw and I'm stuck.

What my search and replace does is, file the 'title' attributes in html tags and convert them to a mouseover javascript. e.g:

Code:

        <a href="http://website.com" title="That's website">
        <a href='http://another.com' title='This website'>
        <hr title="Horizontal Ruler" />
        <hr title="No space"/>

I hope you understand the differences in the 4 tags (double quote, single quote, space and slash). My search and replace will make those tags into these:

Code:

        <a href="http://website.com" onMouseOver="overlib('That\'s website')">
         <a href='http://another.com' onMouseOver="overlib('This website')">
         <hr onMouseOver="overlib('Horizontal Ruler')" />
         <hr onMouseOver="overlib('No Space')"/>

It works well but the flaw is, when there is an empty title attributes,

Code:

        <a href="http://empty.com" title="">Empty</a><a href="http://null.com">null</a>

It will become this :-

Code:

        <a href="http://empty.com" onMouseOver="overlib('\">Empty</a><a href=')">"http://null.com">null</a>

Why?? Because it assumed in the title="", the second quote is the content which it should take, up to the next quote that arrive, which is href=".

Here's my regular expression code that I've made :-

PHP Code:

     $search  = '/title=[\"|\'|](.+?)[\"|\'|](\s|\>|\/)/is';
      $replace = 'onmouseover="overlib(\' ' . addslashes('$1') . ' \')" $2';
      $content = preg_replace($search,$replace,$content); 

$1 is the content inside the title attribute and $2 is the end part of it, be it a space, closing angle bracket (>) or a slash.

To further explain my regular explression, the [\"|\'|] will look for the quote in the attributes. The (.+?) gets the content in between the next [\"|\'|]. And the (\s|\>|\/) looks for space, closing angle bracket (>) or slash.

Thanks for your help..
