Elements and Tags

• Elements are delimited by a start-tag like <LENGTH> and a matching end-tag like </LENGTH>:

  <LENGTH>6:20</LENGTH>

• Elements contain content which can be text, child elements, or both:

    <LENGTH>6:20</LENGTH>
    <PRODUCER>
      <NAME><GIVEN>Jacques</GIVEN> <FAMILY>Morali</FAMILY></NAME>
    </PRODUCER>
    <PARAGRAPH>
       The <ARTIST>Village People</ARTIST>
       were a popular <GENRE>Disco</GENRE> band in the 1970's
    </PARAGRAPH>

• The element is the tags plus the content.

• Empty-element tags both start and end an element:

  <PHOTO/>

  This element has no content. It is equivalent to

  <PHOTO></PHOTO>

• Elements can have attributes:

  <PHOTO xlink:type="simple" xlink:show="onLoad" xlink:href="hotcop.jpg" ALT="Victor Willis in Cop Outfit" WIDTH="100" HEIGHT="200"/>
