How to parse the string using TBXML in iphone sdk? - objective-c

Question

I tried to parse following String using TBXML.
<panel><start><post_id>4</post_id><user_id>2</user_id><post>Hyder here</post><created_on>2012-01-09 06:36:59</created_on><likes>0</likes><noc>0</noc><status>A</status></start><start><post_id>3</post_id><user_id>2</user_id><post>Hello hyder here</post><created_on>2012-01-09 06:34:09</created_on><likes>0</likes><noc>0</noc><status>A</status></start><start><post_id>2</post_id><user_id>0</user_id><post>Hi, This is Syed Hyder....</post><created_on>2012-01-09 01:07:36</created_on><likes>0</likes><noc>0</noc><status>A</status></start><start><post_id>1</post_id><user_id>0</user_id><post>Hello, gaurav....How are you.</post><created_on>2012-01-09 01:05:11</created_on><likes>0</likes><noc>0</noc><status>A</status></start></panel>
My code: -
NSMutableArray *newArr = [[NSMutableArray alloc] init];//21
RXMLElement *rxml = [[RXMLElement alloc] initFromXMLString:response];
[rxml iterate:#"panel.start" with:^(RXMLElement *start) {
ModelPost *newPost = [[ModelPost alloc] init];
newPost.message = [NSString stringWithFormat:#"%#", [start child:#"post"]];
NSLog(#"Post = %#", [start child:#"post"]);
[newArr addObject:newPost];
}];
but I am unable to do it or enter in the iterate loop.
Please help me to over come this by sample code, suggestions and tutorials.
Thanks in Advance....

- (void)xmlparserurl{
//xml data url calling....
tbxml = [[TBXML tbxmlWithURL:[NSURL URLWithString:#"http://karen.webmascot.com/iapi/orders.php?max_count=10"]] retain];
records = [NSMutableArray array];
[records retain];
//retrieving all data from the xml
if (tbxml.rootXMLElement){
NSLog(#"inserting");
[self traverseElement:tbxml.rootXMLElement];
}
[tbxml release];
}
- (void)traverseElement:(TBXMLElement *)element {
do {
//NSLog(#"%#",[TBXML elementName:element]);
if (element->firstChild)
[self traverseElement:element->firstChild];
if ([[TBXML elementName:element] isEqualToString:#"start"]) {
//NSLog(#"xml element checking");
TBXMLElement *id = [TBXML childElementNamed:#"attribute name" parentElement:element];
//inserting into the mutable array
[records addObject:[NSArray arrayWithObjects:
[TBXML textForElement:elementname],
[TBXML textForElement:elementname],
[TBXML textForElement:elementname],nil]];
}
} while ((element = element->nextSibling));
[self.tableview reloadData];
}
i am only sending the code of retrieving the xml data. i am also sending the tutorial where you will get the answer of your further question.
