The AppML Document

With AppML, the <appml> element defines an AppML application.

The AppML Element

AppML uses an <appml> document to describe an AppML application. Inside the <appml> document, the <database> element is used to describe a connection to a database. Other elements, like the <htmlreport> element and the <htmlform> element, are used to describe different parts of the application.

<appml>

<database>
  <connection>music_db</connection>
  <sql>select title,artist,year from cd_catalog</sql>
</database>

</appml>

A view of the database content is displayed below:

AppML Sub Elements

The following sub elements can be used to add more information to the application:

• title

• filters
• header
• footer
• htmlreport
• xmlreport

The Title Element

The AppML <title> element defines a title for the application.

The title will be displayed in the browser caption, and as a default header for HTML reports and other output.

The Stylesheet Element

The Database Element
