Function: satisfies-condition

satisfies-condition(conditions-list as item()*, tokens-list as item()*, index as item()*) as xs:boolean

Description

A recursive function that checks a series of conditions against a series of condition tokens and returns true if there is a match. It takes account of conditions joined by a plus sign, returning true only if both conditions are satisfied. This is a helper function for the sf:conditions-met function.

Return value

Return type: xs:boolean

True if the conditions match, otherwise false.
