  • Method Details

    • isName

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

    • 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
      Returns:
      true if the value is a legal "unqualified" XML name

    • 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
      Returns:
      true if the value is a legal "qualified" XML name

    • 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
      Returns:
      true if the identifier is a "name token"

    • 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
      Returns:
      true if the identifier is a "name token"
