* xmlXPathCompareNodeSetString: * @ctxt: the XPath Parser context * @inf: less than (1) or greater than (0) * @strict: is the comparison strict * @arg: the node set * @s: the value * * Implement the compare operation between a nodeset and a string * @ns < @val (1, 1, ... * @ns <= @val (1, 0, ... * @ns > @val (0, 1, ... * @ns >= @val (0, 0, ... * * If one

 * Returns 0 or 1 depending on the results of the test.
