Validation of dynamic web pages generated by an Embedded Scripting language

This paper attempts to provide insight as to how to guarantee a statement like: My PHP script produces WML. To expand a little, the emphasis is to ensure that a script always produces a valid WML page. The context is where pages in a web-site are being created by an embedded scripting language (like PHP, ASP, Perl) and also that the resulting pages are to conform to a strict tagged mark-up scheme like WML or XHTML. Although there are validators for static pages there is nothing available to check that a page containing embedded scripting will (always) generate valid documents. What is required is a validator for dynamic web pages.
