How do I check dynamic sites like PHP and ASP sites?
CSE HTML Validator is not designed to check raw/unprocessed ASP and PHP files (though it may still be useful in some cases, depending upon the structure of the document). We recommend that instead of checking the raw documents, that the output of the dynamic pages be checked instead. CSE HTML Validator Std/Pro is great for checking the HTML/XHTML output of dynamic scripts! Simply use the integrated web browser to browse your site’s dynamic pages while at the same time displaying and checking the HTML output. If any problems are found, then you can correct the script and then reload the page. HTML Validator can then automatically recheck the HTML/XHTML output. There’s also a Firefox extension that lets you check HTML source from within Firefox.
