<c:visit>

Standard JET2 Control Tags

visit

Define content to process for an object found by the parent 'visitor' tag, provided a condition is met. The contents of this tag are evaluated if the current object of the 'visitor' iteration satisfies the 'test' XPath expression.

The 'test' XPath expression is relative to the current object of the parent 'visitor' tag. If the 'test' XPath expression is does not result in a boolean value, then it is converted to a boolean value according the the XPath 1.0 specification. In particular, if the XPath expression results in a set of objects, then 'test' is considered to be true if and only if the set is not empty.

Note that more than one 'visit' tag may be executed for the same object identified by the parent 'visitor' tag.
