I have a content that returns HTML as a string. I need to add a specific class for elements that contains inline background-color or color. Normally we can find the class or id name and add or remove classes. How do I manipulate HTML string here?
<div style="font-size : 13px; font-family : Arial, Helvetica, sans-serif; ">
<span class="x_965909101highlight" style="background-color : rgb(255, 255, 255); "><span class="x_965909101font" style="font-family : tahoma, arial, helvetica, sans-serif, sans-serif; "><span class="x_965909101size" style="font-size : 13px; "> please check the below concern and advice.<br /><br />Cx concern: </span></span></span></div>
