The data comes smoothly.
But problems have Turkish characters.
Should come as "Düzce" but "ÜZCE" comes.. And,
"Akçakoca" cell in view "çakoca" comes..

Your problem in -(void) parser:(NSXMLParser *)parser foundCharacters:(NSString *)string method. This method can be called more then once for each tag.
Try change your code:
-(void) parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
if (currentNodeContent == nil) currentNodeContent = [NSMutableString new];
[currentNodeContent appendString:[string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]];
}
As alternative you can use XMLConverter for converting your XML to NSDictionary.
This code :
[XMLConverter convertXMLURL:[NSURL URLWithString:#"http://bykrkc.com/test.xml"] completion:^(BOOL success, NSMutableDictionary *dictionary, NSError *error) {
NSArray *elements = dictionary[#"DocumentElement"][#"sehirler"];
for (NSDictionary *dic in elements) {
NSLog(#"%#", dic[#"ad"]);
}
}];
executed with result:

I am able to parse the xml data and able to display it in the console, but not able to display that data in the UITextField or in UILabel.
I tried to assign to textfield in the viewDidLoad method also.
The following is my code,
NSMutableString *currentNodeContent;
NSXMLParser *parser;
ViewController *currentProfile;
bool isStatus;
ViewController *xmlParser;
-(id)loadXMLByURL:(NSString *)urlString
{
_profile = [[NSMutableArray alloc] init];
NSURL *url = [NSURL URLWithString:urlString];
NSData *data = [[NSData alloc] initWithContentsOfURL:url];
parser = [[NSXMLParser alloc] initWithData:data];
parser.delegate = self;
[parser parse];
return self;
}
-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
currentNodeContent = (NSMutableString *) [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
}
-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
if([elementName isEqualToString:#"profileinfo"])
{
currentProfile = [ViewController alloc];
isStatus = YES;
}
if([elementName isEqualToString:#"first_name"])
{
currentProfile = [ViewController alloc];
isStatus = YES;
}
}
-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
if([elementName isEqualToString:#"first_name"])
{
currentProfile.firstName = currentNodeContent;
NSLog(#"%#",currentProfile.firstName);
first_Name.text = currentNodeContent;//UITextField
first_name.text = currentNodeContent;//Label
}
if([elementName isEqualToString:#"last_name"])
{
currentProfile.lastName = currentNodeContent;
NSLog(#"%#",currentProfile.lastName);
last_Name.text = currentProfile.lastName;
}
if([elementName isEqualToString:#"profileinfo"])
{
[self.profile addObject:currentProfile];
currentProfile = nil;
currentNodeContent = nil;
}
}
- (void)viewDidLoad
{
[super viewDidLoad];
xmlParser = [[ViewController alloc] loadXMLByURL:#"http://www.mxxxxx.net/xxx/xxxxx.aspx?type=proifileinfo&loginid=xxx#gmail.com"];
}
Instead of assigning the values directly to the 'UITextField' or 'UILabel', have the values stored in a string. And when the parsing action completed, assign the string value to the 'UITextField' or 'UILabel'; Probably you should do that in '-viewWillAppear' method :-)
Create a IBOutlet UILabel *label; in the interface, connect it in Interface Builder, and then you can set the text of it by label.text = #"Anything";
I have also the same problem while parsing XML parser.
currentNodeContent = (NSMutableString *) [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
}
You are using the above line to trim spaces and tabs. But sometimes It does not work.
So, I implement the following code. The code may be useful to you.
NSString *sname = [currentNodeContent stringByReplacingOccurrencesOfString:#"\n" withString:#""];
NSString *actualString = [sname stringByReplacingOccurrencesOfString:#"\t" withString:#""];
Then pass the actualString to whatever you required.
I have ran into a peculiar problem with NSXMLParser.
For some reason it cuts out all the characters in front of all the norwegian characters æ, ø and å.
However, the problem seems to be the same with all non a-z characters.(All foreign characters)
Examples:
Reality: Mål
Output: ål
Reality: Le chant des sirènes
Output: ènes
Heres an example from the log where I have printed out the string from:
- (void) parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
Log:
2012-02-22 14:00:01.647 VotePlayClient[2776:207] found characters: Le chant des sir
2012-02-22 14:00:01.647 VotePlayClient[2776:207] found characters: ènes
You can clearly see that it jumps to a new line whenever it encounters a foreign letter.
I believe that I have to figure out how to append the string or something to that effect.
Here are the NSXMLParser files:
SearchXMLParser.h
#import <Foundation/Foundation.h>
#import "Search.h"
#interface SearchXMLParser : NSObject <NSXMLParserDelegate>
{
NSMutableString *currentNodeContent;
NSMutableArray *searchhits;

return self;

{

currentSearch.artist = [trackhits objectAtIndex:1];
currentSearch.album = [trackhits objectAtIndex:2];
[trackhits removeAllObjects];
[searchhits addObject:currentSearch];
[currentSearch release];
currentSearch = nil;
[currentNodeContent release];
currentNodeContent = nil;
}
}
- (void) parser:(NSXMLParser *)parser foundCharacters:(NSString *)string

currentNodeContent = (NSMutableString *) [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
}
- (void) dealloc
{
[parser release];
[super dealloc];
}
#end
I have already checked SO for answers and found a couple of similar posts, but nothing that gave a clear solution to this problem.
Can anyone shed some light on this problem? :) Any help is much appreciated!
your parser:foundCharacters: method does not work as it should.
This is from the NSXMLParserDelegate Protocol Reference
The parser object may send the delegate several parser:foundCharacters: messages to report the characters of an element. Because string may be only part of the total character content for the current element, you should append it to the current accumulation of characters until the element changes.
you could try something like this (ARC):
- (void) parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
NSLog(#"found characters: %#", string);
if (!currentNodeContent) {
currentNodeContent = [[NSMutableString alloc] init];
}
[currentNodeContent appendString:string];
}
- (void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
// your code here
// when you are done with the string:
currentNodeContent = nil;
}
I'm not sure what I am doing wrong. I have a URL leading to an XML tree that looks like:
<result>
...
<title>
...
</title>
<body>
...
</body>
...
</result>
I just need to parse the file and get the title and body. Here is my object.h:
#import <Foundation/Foundation.h>
#interface Object : NSObject
{
NSString *title;
NSString *description;
}
#property (nonatomic, retain) NSString *title;
#property (nonatomic, retain) NSString *description;
#end
And here is Object.m:
#import "Object.h"
#implementation Object
#synthesize title, description;
-(void) dealloc
{
[title release];
[description release];
[super dealloc];
}
#end
Here is my XMLParser.h:
#import <Foundation/Foundation.h>
#import "Object.h"
#interface XMLParser : NSObject <NSXMLParserDelegate>
{
NSMutableString *currentNodeContent;
NSMutableArray *arrayOfObjects;
NSXMLParser *parser;
Object *currentObject;
}
#property (readonly, retain) NSMutableArray *arrayOfObjects;
-(id) loadXMLbyURL:(NSString *)urlString;
#end
And finally, XMLParser.m:
#import "XMLParser.h"
#import "Object.h"
#implementation XMLParser
#synthesize arrayOfObjects;
-(id) loadXMLbyURL:(NSString *)urlString
{
arrayOfObjects = [[NSMutableArray alloc] init];
NSURL *url = [NSURL URLWithString:urlString];
NSData *data = [[[NSData alloc] initWithContentsOfURL:url] autorelease];
parser = [[NSXMLParser alloc] initWithData:data];
parser.delegate = self;
[parser parse];
return self;
}
-(void) dealloc
{
[parser release];
[super dealloc];
}
-(void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
if([elementName isEqualToString:#"result"])
{
currentObject = [Object alloc];
}
}
-(void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
if([elementName isEqualToString:#"title"])
{
currentObject.title = currentNodeContent;
}
if([elementName isEqualToString:#"body"])
{
currentObject.description = currentNodeContent;
}
if([elementName isEqualToString:#"result"])
{
[arrayOfObjects addObject:currentObject];
[currentObject release];
currentObject = nil;
[currentNodeContent release];
currentNodeContent = nil;
}
}
-(void) parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
currentNodeContent = (NSMutableString *) [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
}
#end
In my main code I make a call to XML parser like this:
xmlParser = [[XMLParser alloc] loadXMLbyURL:#"www.websiteWithXML.com"];
However nothing is being placed into my arrayOfObjects (I know this because when I tell a tableview to have as many rows as my array, there are no rows).
please help!!! Thank you in advance!
Not sure if this will help...
Try changing:
arrayOfObjects = [[NSMutableArray alloc] init];
To:
arrayOfObjects = [[NSMutableArray alloc] initWithCapacity:0];
Other than that it appears that your code is fine. Also just because your table isn't loading anything doesn't mean that you do not have objects in your array. Use breakpoints to take a look at your data after you finish parsing and before you try to load your tableview.
Try resetting currentNodeContent inside each of your element starts. For example:
-(void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
if([elementName isEqualToString:#"result"])
{
currentObject = [Object alloc];
}
else if ([elementName isEqualToString:#"title"] || [elementName isEqualToString:#"body"])
{
[currentNodeContent setString:#""];
}
}
Then, when you receive characters do an append:
-(void) parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
[currentNodeContent appendString:[string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]];
}
By doing this, you handle the situation where a foundCharacters gets multiple times to capture all of the characters within a given element.

I have an xml file I am parsing.
NSURL *url = [NSURL URLWithString:#"url.xml"];
NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60];
self.downloadData = [[NSMutableData alloc] initWithLength:0];
self.connection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];
I have all the connections working and I thought I had the parsing working but I am having issues and do not know what I am doing wrong.
my didStartElement:
-(void) parser:(NSXMLParser *) parser didStartElement:(NSString *) elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *) qName attributes:(NSDictionary *) attributeDict {
if ([elementName isEqualToString:kimgurl])
{
elementFound = YES;
}
}
foundCharacter:
-(void)parser:(NSXMLParser *) parser foundCharacters:(NSString *)string {
if (elementFound == YES) {
if(!currentValue)
{
currentValue = [[NSMutableString alloc] init];
}
[currentValue appendString: string];
}
}
then didEndElement:
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
if (elementFound) {
if ([elementName isEqualToString:kimgurl]) {
NSLog(#"imgurl: %#", currentValue);
imageItems.imageURL = currentValue;
NSLog(#"elname: %#", elementName);
NSLog(#"img: %#", kimgurl);
[currentValue setString:#""];
NSLog(#"imageitem: %#", imageItems.imageURL);
}
}
}
I have the NSLogs there because imageItems.imageURL is null. This is a class file that is like this.
ImageItems.h
#interface ImageItems : NSObject {
//parsed data
NSString *imageURL;
}
#property (nonatomic, retain) NSString *imageURL;
#end
ImageItems.m
#import "ImageItems.h"
#implementation ImageItems
#synthesize imageURL;
-(void)dealloc
{
[imageURL release];
[super dealloc];
}
#end
As you can tell by my code I am new to objective-c.
currentValue has the value Im looking for. Why is imageItems null? What am I missing?
I don't see the assignment of "imageItems" anywhere in your code. You probably need to assign it to an instance of ImageItems at some point. Perhaps with self.imageItems = [[[ImageItems alloc] init] autorelease] or imageItems = [[ImageItems alloc] init];?
