    public interface XMLDTDContentModelHandler
    The DTD content model handler interface defines callback methods to report information items in DTD content models of an element declaration. Parser components interested in DTD content model information implement this interface and are registered as the DTD content model handler on the DTD content model source.

    • Field Detail

      • SEPARATOR_CHOICE

        static final short SEPARATOR_CHOICE
        A choice separator for children and mixed content models. This separator is used to specify that the allowed child is one of a collection.

        For example:

         <!ELEMENT elem (foo|bar)>
         <!ELEMENT elem (foo|bar+)>
         <!ELEMENT elem (foo|bar|baz)>
         <!ELEMENT elem (#PCDATA|foo|bar)*>
         
        See Also:
        SEPARATOR_SEQUENCE, Constant Field Values
      • SEPARATOR_SEQUENCE

        static final short SEPARATOR_SEQUENCE
        A sequence separator for children content models. This separator is used to specify that the allowed children must follow in the specified sequence.

         <!ELEMENT elem (foo,bar)>
         <!ELEMENT elem (foo,bar*)>
         <!ELEMENT elem (foo,bar,baz)>
         
        See Also:
        SEPARATOR_CHOICE, Constant Field Values
      • OCCURS_ZERO_OR_ONE

        static final short OCCURS_ZERO_OR_ONE
        This occurrence count limits the element, choice, or sequence in a children content model to zero or one. In other words, the child is optional.

        For example:

         <!ELEMENT elem (foo?)>
         
        See Also:
        OCCURS_ZERO_OR_MORE, OCCURS_ONE_OR_MORE, Constant Field Values
      • OCCURS_ZERO_OR_MORE

        static final short OCCURS_ZERO_OR_MORE
        This occurrence count limits the element, choice, or sequence in a children content model to zero or more. In other words, the child may appear an arbitrary number of times, or not at all. This occurrence count is also used for mixed content models.

        For example:

         <!ELEMENT elem (foo*)>
         <!ELEMENT elem (#PCDATA|foo|bar)*>
         
        See Also:
        OCCURS_ZERO_OR_ONE, OCCURS_ONE_OR_MORE, Constant Field Values
      • OCCURS_ONE_OR_MORE

        static final short OCCURS_ONE_OR_MORE
        This occurrence count limits the element, choice, or sequence in a children content model to one or more. In other words, the child may appear an arbitrary number of times, but must appear at least once.

        For example:

         <!ELEMENT elem (foo+)>
