iphone - Get Correct Output : NSXML Parser -


my xml file :

<?xml version="1.0" encoding="utf-8"?> <plist version="1.0">     <count count="3" />     <spac>         <opt>aa</opt>         <opt>bb</opt>     </spac> </plist>

i have used following line of code nsxml parssr :

- (void)parser:(nsxmlparser *)parser didstartelement:(nsstring *)elementname   namespaceuri:(nsstring *)namespaceuri qualifiedname:(nsstring *)qualifiedname  attributes:(nsdictionary *)attributedict {  if([elementname isequaltostring:@"spaces"]) {     //initialize array.     appdelegate.api = [[nsmutablearray alloc] init];  }  }  - (void)parser:(nsxmlparser *)parser foundcharacters:(nsstring *)string {  [appdelegate.api addobject:string];     nslog(@"the count :%d", [appdelegate.api count]); }  - (void)parser:(nsxmlparser *)parser didendelement:(nsstring *)elementname  namespaceuri:(nsstring *)namespaceuri qualifiedname:(nsstring *)qname { if([elementname isequaltostring:@"spaces"])     return; }

but getting following output @ gdb , i'm unable figure out reason :

2012-06-05 02:20:57.940 xml[490:f803] count :0 2012-06-05 02:20:57.942 xml[490:f803] count :0 2012-06-05 02:20:57.943 xml[490:f803] count :1 2012-06-05 02:20:57.944 xml[490:f803] count :2 2012-06-05 02:20:57.945 xml[490:f803] count :3 2012-06-05 02:20:57.946 xml[490:f803] count :4 2012-06-05 02:20:57.946 xml[490:f803] count :5 2012-06-05 02:20:57.948 xml[490:f803] count :6 2012-06-05 02:20:57.948 xml[490:f803] count :7 2012-06-05 02:20:57.949 xml[490:f803] count :8

can please me out ?? new objective c. thanks.

the reason why have 2 zeros printed out because in first callback create new mutable array when element spaces.

if([elementname isequaltostring:@"spaces"]) { //<- check spaces create array     //initialize array.     appdelegate.api = [[nsmutablearray alloc] init];  }

however, - (void)parser:foundcharacters: called each element characters found in. first nodes found added nil array , print 0. node found after spaces continue adding unwanted characters it. if had xml looked following can see happening.

<xml>    <node1>text found gets added nil array (prints 0 count)</node1>    <node2>more text found gets added nil array (prints 0 count)</node2>    <spaces>this spaces text added array correctly</spaces>    <node4>this text added non-nil array , appear spaces</node4> </xml>
