Tag Structure

All rules governing well-formed XML apply to the scripting of Interactive XML applications. These won’t be detailed here, but following are some useful tips relating to tag structure:

1. Every opened tag must have a corresponding closing tag. For example:

     <a_tag>some_text</a_tag>

or

     <a_tag name="some_text"/>

2. Tags must be opened and closed at the same level. For example:

Incorect:

     <tag1>
           <tag2>some_text</tag1>
     </tag2>

Correct:

     <tag1>
          <tag2>some_text</tag2>
     </tag1>

3. The correct hierarchy of tags as described in this documentation must be respected. For example:

Incorrect:

     <media>
          <medias>
               <file>a_file.mp4</file>
          </medias>
     </media>

Correct:

     <medias>
          <media>
               <file>a_file.mp4</file>
          </media>
     </medias>

This is referred to in the Interactive XML Glossary later in this document as the parent-child relationship.

Note that you will NOT get an XML error when you debug the above incorrect code in a browser. However, the file specified in <file> will never be called.
