Not able to get data using NSXmlParser - ios

Question

I am using NSXmlParser to get data from XML. In the parser delegate method I have:
- (void)resetPassCallback: (NSData*) data{
NSLog(#"start parsing the data");
NSXMLParser *nsXmlParser = [[NSXMLParser alloc] initWithData:data];
[nsXmlParser setDelegate:self];
BOOL success = [nsXmlParser parse];
if (success) {
NSLog(#"No errors %#", xmlArray);
} else {
NSLog(#"Error parsing document!");
}
}
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *)qualifiedName attributes: (NSDictionary *)attributeDict
{
element = elementName;
if([elementName isEqualToString:#"User"])
{
XmlDict = [[NSMutableDictionary alloc]init];
userId =[[NSMutableString alloc]init];
screenName =[[NSMutableString alloc]init];
xmlArray = [[NSMutableArray alloc]init];
}
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
NSLog(#"foundCharacters ::::: %# :::: ", string);
[xmlArray addObject:string];
}
Although I am able to parse the data, I am not getting the complete data. In the console, the log shows:
foundCharacters ::::: 200 ::::
foundCharacters ::::: f1f47453-04d7-20c8-a9e1-406fdc89a2da ::::
foundCharacters ::::: test ::::
foundCharacters ::::: 62e2092a-eb6e-44ad-7a7b-3deb976569c1 ::::
foundCharacters ::::: Thomas ::::
xmlArray contents : (
"62e2092a-eb6e-44ad-7a7b-3deb976569c1",
Thomas
)
As you can see, why am I not getting the “test” and other values in the xmlArray.

Answer 1

why use for mutableArray. simply try this
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
if(!currentElementValue)
currentElementValue = [[NSMutableString alloc] initWithString:string];
else
[currentElementValue appendString:string];
NSLog(#"Processing Value: %#", currentElementValue);
}

Answer 2

I hope that, the Array is getting re-initialed at every time of NSXMLParser delegates called .
You need to initialise the Array, before the NSXMLParser delegates
called.
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *)qualifiedName attributes: (NSDictionary *)attributeDict
{
//Don't initialise your NSArray here
}
}
-(void) parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{
NSLog(#"foundCharacters ::::: %# :::: ", string);
[xmlArray addObject:string];
}

Use xmlArray = [[NSMutableArray alloc]init]; in
- (void)resetPassCallback: (NSData*) data{
NSLog(#"start parsing the data");
xmlArray = [[NSMutableArray alloc]init];
NSXMLParser *nsXmlParser = [[NSXMLParser alloc] initWithData:data];
[nsXmlParser setDelegate:self];
BOOL success = [nsXmlParser parse];
if (success) {
NSLog(#"No errors %#", xmlArray);
} else {
NSLog(#"Error parsing document!");
}
}
not in
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *)qualifiedName attributes: (NSDictionary *)attributeDict
{
}
