<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.

Attributes

source="plugin": The source from which the data should be fetched.
scope="name" (The emit source): The name of the scope within the emit tag.
maxrows="number": Limits the number of rows to this maximum.
skiprows="number": Makes it possible to skip the first rows of the result. Negative numbers means to skip everything execept the last n rows.
rowinfo="variable": The number of rows in the result, after it has been limited by maxrows and skiprows, will be put in this variable, if given.
do-once: Indicate that at least one loop should be made. All variables in the emit scope will be empty.

&_.counter; (provided by RXML 2 parser)

Gives the current number of loops inside the <emit> tag.
