Evaluate any rules contained by given XML element.

Parameters

[in]	xml	XML element to check for rules
[in]	node_hash	Node attributes to use when evaluating expressions
[in]	now	Time to use when evaluating expressions
[out]	next_change	If not NULL, set to when evaluation will change

Returns: TRUE if no rules, or any of rules present is in effect, else FALSE

	)

Evaluate one rule subelement (pass/fail)

A rule element may contain another rule, a node attribute expression, or a date expression. Given any one of those, evaluate it and return whether it passed.

Parameters

[in]	expr	Rule subelement XML
[in]	node_hash	Node attributes to use when evaluating expression
[in]	role	Resource role to use when evaluating expression
[in]	now	Time to use when evaluating expression
[out]	next_change	If not NULL, set to when evaluation will change
[in]	match_data	If not NULL, resource back-references and params

Returns: TRUE if expression is in effect under given conditions, else FALSE
