<emit></emit>

Provided by module: RXML 2 parser

<emit> is a generic tag used to fetch data from a provided source, loop over it and assign it to RXML variables accessible through entities.

Occasionally an <emit> operation fails to produce output. This might happen when <emit> can't find any matches or if the developer has made an error. When this happens the truthvalue of that page is set to false. By using <else> afterwards it's possible to detect when an <emit> operation fails.
