iphone problem with KIssXML parser

I need quick help

structure of xml is like this

<VacancyList generated="2011-08-26T09:06:13" xsi:schemaLocation="http://www.abc.com/dtd/vacancy-list.xsd"><Vacancy id="157890" date_start="2010-10-12" date_end="2011-12-31" reference_number=""><Versions><Version language="nb">

and I am using KissXML like this

DDXMLDocument *theDocument = [[DDXMLDocument alloc] initWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"https://pwc.easycruit.com/export/xml/vacancy/list.xml"]] options:0 error:&error];
NSArray* resultNodes = nil;
resultNodes = [theDocument nodesForXPath:@"Versions" error:&error];

XML is case sensitive. You are looking for "versions" in your xpath query and not "Versions" (which is what exists in your document). I think that is your problem.
