W3C HTML Validation Service

Developer News

JBoss Portal 5 Release Easier to Use

Based on Gerald Oskobioni's kinder, gentler HTML validation service the W3C's HTML validator is the defacto standard against which all others are measured. This is a gateway to their easy-to-use HTML validation service (at http://validator.w3.org) based on an SGML parser. It checks HTML documents for compliance with W3C HTML Recommendations and other HTML standards.

Enter the location of a document you would like validated:

Location:
Include Weblint results run Weblint in "pedantic" mode
Show source input Show an outline of this document
Show parse tree don't show attributes in the parse tree

NOTE: To use the W3C HTML 4.0 Recommendation, start your document with one of the following doctype declarations:

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN"
            "http://www.w3.org/TR/REC-html40/strict.dtd">
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"
            "http://www.w3.org/TR/REC-html40/loose.dtd">
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Frameset//EN"
            "http://www.w3.org/TR/REC-html40/frameset.dtd">
