#import "SSJuju.h"

NSString *htmlstr = @"<html><a class='awesome'><b id='1'>One</b><b id='2'>Two</b></a></html>";
NSData *htmlData = [htmlstr dataUsingEncoding:NSASCIIStringEncoding];
SSJuju *doc = [[[SSJuju alloc] initWithHTMLData:htmlData] autorelease];
NSArray *elements = [doc search:@"//a[@class='awesome']"];
for (SSNode *e in elements) {
	SSINode *bNode = [e firstChild];								// Node "b"
	do {
		NSString *idValue = [bNode attributeByName:@"id"]; 			// Easy access to attribute
		NSString *nodeName = [bNode name];							//tag name
		NSString *nodeValue = [[bNode firstChild] description];
		NSLog(@"%@ : %@ : %@",idValue,nodeName,nodeValue);
	} while ((bNode = bNode.right));								// Access to sibling node
}
