Grouping Elements

Children can be grouped using parentheses. Thus, the following DTD snippet would specify that a CONTACT element could have one or more sets of NAME/EMAIL children such that NAME always precedes EMAIL.

	<!ELEMENT CONTACT (NAME, EMAIL)+>
	<!ELEMENT NAME (#PCDATA)>
	<!ELEMENT EMAIL (#PCDATA)>

That would look something like the following:

        <CONTACT>

        <NAME>Jim Sanger</NAME>
        <EMAIL>sanger@sanger.com</EMAIL>

        <NAME>James Sanger</NAME>
        <EMAIL>james.sanger@sanger.com</EMAIL>

        <NAME>Kris Kringle</NAME>
        <EMAIL>santa@sanger.com</EMAIL>

        </CONTACT>
