Why is CSE HTML Validator Better?

We’ve provided examples below that show that CSE HTML Validator can find problems and issues that other syntax checkers and validators (such as the popular W3C HTML Validator) cannot find. The testing was done with recent versions of CSE HTML Validator. Validate the source HTML document using the W3C HTML Validator and see how many problems/issues it misses (it misses ALL of them as of July 9, 2007). Even with all these issues, the W3C validator says that you may want to place an icon on your page to show your readers that you’ve taken the care to create an “interoperable” web page. We don’t consider a page with so many problems “interoperable”, and neither should you.

Why does it miss these issues? A DTD validator like the W3C validator and other validators claiming to be based on real SGML parsers, are technically incapable of finding certain problems because they are more limited in the number of problems that they can check for. These validators are only concerned about strict adherence to the specifications. They consider many things supported by Internet Explorer and other browsers illegal. They also consider bad attribute values that don’t work in popular browsers to actually be legal (like width=”really wide”). These methods of checking for problems do not reflect upon “real-life” situations.

CSE HTML Validator is designed to be a “real-life” validator. As such, it is not limited to adhering to strict HTML specifications. Instead of generating errors for issues that are fine in the real-world, CSE HTML Validator understands them. Instead of not generating errors for bad attribute values, it reports them. CSE HTML Validator can find many more problems or potential problems than other syntax checkers and validators can find. If you do wish to adhere to the standards as closely as possible, then CSE HTML Validator will help you do that as well, with its “standards compliant check”. Also, CSE HTML Validator Std/Pro v8.0 and above now include a DTD based validator for when you’d like to use one.

In addition to all of the above, CSE HTML Validator also checks CSS, links, and spelling. It also checks for accessibility issues. If you’re concerned about search engine rankings (and you probably are), then you’ll be glad to know that CSE HTML Validator also generates messages that may help you increase your search engine rankings.
