How to parse an HTML with PHP/ASP.NET?

The question is not really about parsing the HTML, but rather parsing the HTML and adding elements to the DOM according to the HTML tags. For example - I want to be able to take an HTML page, add attribute to the HTML tags - such as "class='replace'", put some PHP/ASPNET code in the page (make an ASPX page with ASPNET or put some include with PHP) and make them parse the page every time it is accessed and manipulate the DOM of the tags marked as 'class="replace". For example if I have <开发者_运维知识库; div class='replace'>< /div>, after I run the script I'll get something like < div class='replace'>This is a new text< /div>

Thanks, Roman
