    • Method Detail

      • isName

        public static boolean isName​(String value)
        Returns true if the value is a legal XML name.
        Parameters:
        value - the string being tested

      • isUnqualifiedName

        public static boolean isUnqualifiedName​(String value)
        Returns true if the value is a legal "unqualified" XML name, as defined in the XML Namespaces proposed recommendation. These are normal XML names, except that they may not contain a "colon" character.
        Parameters:
        value - the string being tested

      • isQualifiedName

        public static boolean isQualifiedName​(String value)
        Returns true if the value is a legal "qualified" XML name, as defined in the XML Namespaces proposed recommendation. Qualified names are composed of an optional prefix (an unqualified name), followed by a colon, and a required "local part" (an unqualified name). Prefixes are declared, and correspond to particular URIs which scope the "local part" of the name. (This method cannot check whether the prefix of a name has been declared.)
        Parameters:
        value - the string being tested

      • isNmtoken

        public static boolean isNmtoken​(String token)
        This method returns true if the identifier is a "name token" as defined in the XML specification. Like names, these may only contain "name characters"; however, they do not need to have letters as their initial characters. Attribute values defined to be of type NMTOKEN(S) must satisfy this predicate.
        Parameters:
        token - the string being tested

      • isNCNmtoken

        public static boolean isNCNmtoken​(String token)
        This method returns true if the identifier is a "name token" as defined by the XML Namespaces proposed recommendation. These are like XML "name tokens" but they may not contain the "colon" character.
        Parameters:
        token - the string being tested
