#import "XMLParser.h"
#implementation XMLParser
- (NSString *)parseXMLFile: (NSURL *) url
{
outstring = [[NSMutableString alloc] init];
NSXMLParser *parser = [[NSXMLParser alloc] initWithContentsOfURL: url];
[parser setDelegate: self];
[parser parse];
[parser release];
return [outstring autorelease];
}
//<boolean xmlns="http://schemas.microsoft.com/2003/10/Serialization/">true</boolean>
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName
attributes:(NSDictionary *)attributeDict
{
if (qName) elementName = qName;
if (elementName) current = [NSString stringWithString:elementName];
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName
{
current = nil;
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
if (!current) return;
if ([current isEqualToString:#"boolean"])
[outstring appendFormat:#"%#\n", string];
}
// <boolean xmlns="http://schemas.microsoft.com/2003/10/Serialization/">true</boolean>
-(void) parserDidStartDocument:(NSXMLParser *)parser {
NSLog(#"parserDidStartDocument");
}
-(void) parserDidEndDocument: (NSXMLParser *)parser {
NSLog(#"parserDidEndDocument %#", outstring);
}
#end

if you want true value then do following:
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
strVal=string;
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
if([elementName isEqualToString:#"boolean"])
{
//you can get 'true' value here
}
}
