I have an URL -----> 182.72.253.75/test/surya/telugu.html
And this url contains some information in telugu language..
Now I need help in the following aspects---->
1) How to parse that html url..
2) How to display the information in that link in a UILabel in iphone simulator...(Because the information is in telugu language not in english language) ..
Thanks in Advance....
Here I have solved my problem...
Actually the URL contains...

The background source code of this This HTML page is as follows...
http://ashokios.blogspot.in/2013/02/background-sourcetemporary-post.html
But this is not in correct formate
so..,
1)Need to get the correct formate..
2)Need to convert into Dictionary.
Here we need two custom classes
XMLReader and GDataXMLDocument..
Now the solution is...
NSString *serverResponseStr=[XMLReader getResponseForService:#"http://182.72.253.75/test/surya/telugu.html" withParametersString:nil];
NSString *validXMLstring=[[NSString alloc]init];
GDataXMLDocument *doc = [[GDataXMLDocument alloc]initWithHTMLString:serverResponseStr error:nil];
if (doc)
{
validXMLstring=[[doc rootElement] XMLString];
}
NSDictionary *responseDictionary=[[NSDictionary alloc]init];
responseDictionary=[XMLReader dictionaryForXMLString:validXMLstring error:nil];
NSLog(#"%#",responseDictionary);
NSLog(#"%#",[[[[[[responseDictionary objectForKey:#"html"]objectForKey:#"body"]objectForKey:#"table"]objectForKey:#"tr"]objectForKey:#"td"]objectForKey:#"text"]);
self.myTextView.text=[[[[[[responseDictionary objectForKey:#"html"]objectForKey:#"body"]objectForKey:#"table"]objectForKey:#"tr"]objectForKey:#"td"]objectForKey:#"text"];

im currently trying to parse some json data on the iphone.
I have been trawling the web for examples, but none seem to suit my purpose, i am using SBJson.
What I want is to be able to get an NSArray of Titles, Artisits, Status, etc. so that I can display them on a table view. Any help would be great, so far all i get is an array of "Values".
JSON = {"values":
[
{"Status":"N", "Filename":"RD207T04", "Title":"Simple Man (Explicit)", "Artist":"DIAFRIX F/DANIEL MERRIWE", "Release":"May11"},
{"Status":"N", "Filename":"CR221T27", "Title":"Midnight City", "Artist":"M83", "Release":"Dec11"},
{"Status":"N", "Filename":"ED211T03", "Title":"I\"ll Be Your Man", "Artist":"JAMES BLUNT", "Release":"Jul11"}
]}
You don't want an array of titles, artists, etc. You want the array of NSDictionarys represented by the values key. Then you can do:
cell.textLabel.text = [[valuesArray objectAtIndex:indexPath.row]valueForKey:#"Title"]];
inside your cellForRowAtIndexPath: delegate method. If you do not have this already, this is how to get that array:
NSArray *valuesArray = [[myJsonString JSONValue]objectForKey:#"values"];
Thanks mate, I was definately over complicating things:
The end code was this:
NSArray *valuesArray = [[playlist JSONValue] objectForKey:#"values"];
NSString *test = [[valuesArray objectAtIndex:0]valueForKey:#"Title"];
NSLog(#"test = %#", test);
Now all I have to do is iterate through the set :)
I get from an URL this result :
NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
it looks like this :
[{"modele":"Audi TT Coup\u00e9 2.0 TFSI","modele_annee":null,"annee":"2007","cilindre":"4 cyl","boite":"BVM","transmision":"Traction","carburant":"ES"},
{"modele":"Audi TT Coup\u00e9 2.0 TFSI","modele_annee":null,"annee":"2007","cilindre":"4 cyl","boite":"BVM","transmision":"Traction","carburant":"ES"}]
So it contains 2 dictionaries. I need to take the objects from all the keys from this result. How can I do this?
I tried this : NSDictionary vehiculesPossedeDictionary=(NSDictionary *)result;
and then this : [vehiculesPossedeDictinary objectForKey:#"modele"]; but this is not working.
Please help me... Thanks in advance
What you have is a JSON string which describes an "array" containing two "objects". This needs to be converted to Objective-C objects using a JSON parser, and when converted will be an NSArray containing two NSDictionarys.
You aren't going to be able to get your dictionary directly from a string of JSON. You are going to have to going to have to run it through a JSON parser first.
At this point, there is not one build into the iOS SDK, so you will have to download a third-party tool and include it in your project.
There are a number of different JSON parser, include TouchJSON, YAJL, etc. that you can find and compare. Personally, I am using JSONKit.
#MatthewGillingham suggests JSONKit. I imagine it does fine, but I've always used its competitor json-framework. No real reason, I just found it first and learned it first. I do think its interface is somewhat simpler, but plenty of people do fine with JSONKit too.
Using json-framework:
require JSON.h
...and then
NSString *myJsonString = #"[{'whatever': 'this contains'}, {'whatever', 'more content'}]";
NSArray *data = [myJsonString JSONValue];
foreach (NSDictionary *item in data) {
NSString *val = [item objectForKey:#"whatever"];
//val will contain "this contains" on the first time through
//this loop, then "more content" the second time.
}
If you have array of dictionary just assign objects in array to dictionary like
NSDictionary *dictionary = [array objectAtIndes:0];
and then use this dictionary to get values.
i want to get data between xml tags? how to navigate? and get values..
im using wsdl2objc from google code:http://code.google.com/p/wsdl2objc/
output soapbody follows:
read instruction here: http://code.google.com/p/wsdl2objc/wiki/UsageInstructions
my header file: #import "MService.h"
how to get image source and text value????
please help me....
if([bodyPart isKindOfClass:[types_getFavoriteColorResponseType class]]) {
types_getFavoriteColorResponseType *body = (types_getFavoriteColorResponseType*)bodyPart;
// Now you can extract the color from the response
q.text = body.color;
continue;
}
Ок as far as I understand this is a part which extracts text data from your SOAP response.
BTW you need response to be processed via SAX or DOM? First example in given URL refers to DOM usage, whereas the second to SAX.
More than that I can not tell. Guess you have to read manual or find someone, who worked with this.
Use NSXMLParser, NSXMLParserDelegate for xml parsing, you can get the callbacks with proper values:
parser:didStartElement:namespaceURI:qualifiedName:attributes:
parser:foundCharacters:
parser:didEndElement:namespaceURI:qualifiedName:

hey i got the result using sudzc.com
if ([result isKindOfClass:[MSalesPages class]]) {
NSLog(#"Response");
NSMutableArray* pageData = result.PageData;
for(MSalesPage* page in pageData){
NSLog(#"Inside for loop %#", page.Id);
NSMutableArray* images = page.Images;
NSMutableArray* textData = page.TextData;
for(MSalesImg* img in images){
NSLog(#"Image url %#",img.Src);
}
for(MSalesText* text in textData){
NSLog(#"Product Name %#",text.Value);
}
}
}
carefully check with the above xml, u will get the answer :)
I have a web-service running on Windows Azure which returns JSON that I consume in my iPhone app.
Unfortunately, Windows Azure doesn't seem to support the compression of dynamic responses yet (long story) so I decided to get around it by returning an uncompressed JSON package, which contains a compressed (using GZIP) string.
e.g
{"Error":null,"IsCompressed":true,"Success":true,"Value":"vWsAAB+LCAAAAAAAB..etc.."}
... where value is the compressed string of a complex object represented in JSON.
This was really easy to implement on the server, but for the life of me I can't figure out how to decompress a gzipped NSString into an uncompressed NSString, all the examples I can find for zlib etc are dealing with files etc.
Can anyone give me any clues on how to do this? (I'd also be happy for a solution that used deflate as I could change the server-side implementation to use deflate too).
Thanks!!
Steven
Edit 1: Aaah, I see that ASIHTTPRequest is using the following function in it's source code:
//uncompress gzipped data with zlib
+ (NSData *)uncompressZippedData:(NSData*)compressedData;
... and I'm aware that I can convert NSString to NSData, so I'll see if this leads me anywhere!
Edit 2: Unfortunately, the method described in Edit 1 didn't lead me anywhere.
Edit 3: Following the advice below regarding base64 encoding/decoding, I came up with the following code. The encodedGzippedString is as you can guess, a string "Hello, my name is Steven Elliott" which is gzipped and then converted to a base64 string. Unfortunately, the result that prints using NSLog is just blank.
NSString *encodedGzippedString = #"GgAAAB+LCAAAAAAABADtvQdgHEmWJSYvbcp7f0r1StfgdKEIgGATJNiQQBDswYjN5pLsHWlHIymrKoHKZVZlXWYWQMztnbz33nvvvffee++997o7nU4n99//P1xmZAFs9s5K2smeIYCqyB8/fnwfPyK+uE6X2SJPiyZ93eaX+TI9Lcuiatvx/wOwYc0HGgAAAA==";
NSData *decodedGzippedData = [NSData dataFromBase64String:encodedGzippedString];
NSData* unGzippedJsonData = [ASIHTTPRequest uncompressZippedData:decodedGzippedData];
NSString* unGzippedJsonString = [[NSString alloc] initWithData:unGzippedJsonData encoding:NSASCIIStringEncoding];
NSLog(#"Result: %#", unGzippedJsonString);
After all this time, I finally found a solution to this problem!
None of the answers above helped me, as promising as they all looked. In the end, I was able to compress the string on the server with gzip using the chilkat framework for .net ... and then decompress it on the iphone using the chilkat framework for iOS (not yet released, but available if you email the guy directly).
The chilkat framework made this super easy to do so big thumbs up to the developer!
Your "compressed" string is not raw GZIP'd data, it's in some encoding that allows those bytes to be stored in a string-- looks like base-64 or something like it. To get an NSData out of this, you'll need to decode it into the NSData.
If it's really base-64, check out this blog post an accompanying code:
http://cocoawithlove.com/2009/06/base64-encoding-options-on-mac-and.html
which will do what you want.
Once you have an NSData object, the ASIHTTPRequest method will probably do as you like.
This worked for me:
from a string gzipeed, then base64 encoded
to un-gzipped string (all utf8).
#import "base64.h"
#import "NSData+Compression.h"
...
+(NSString *)gunzipBase64StrToStr:(NSString *)stringValue {
//now we decode from Base64
Byte inputData[[stringValue lengthOfBytesUsingEncoding:NSUTF8StringEncoding]];//prepare a Byte[]
[[stringValue dataUsingEncoding:NSUTF8StringEncoding] getBytes:inputData];//get the pointer of the data
size_t inputDataSize = (size_t)[stringValue length];
size_t outputDataSize = EstimateBas64DecodedDataSize(inputDataSize);//calculate the decoded data size
Byte outputData[outputDataSize];//prepare a Byte[] for the decoded data
Base64DecodeData(inputData, inputDataSize, outputData, &outputDataSize);//decode the data
NSData *theData = [[NSData alloc] initWithBytes:outputData length:outputDataSize];//create a NSData object from the decoded data
//NSLog(#"DATA: %# \n",[theData description]);
//And now we gunzip:
theData=[theData gzipInflate];//make bigger==gunzip
return [[NSString alloc] initWithData:theData encoding:NSUTF8StringEncoding];
}
#end
I needed to compress data on the iPhone using Objective-c and decompress on PHP. Here is what I used in XCode 11.5 and iOS 12.4:
iOS Objective-c Compression Decompression Test
Include libcompression.tbd in the Build Phases -> Link Binary With Library. Then include the header.
#include "compression.h"
NSLog(#"START META DATA COMPRESSION");
NSString *testString = #"THIS IS A COMPRESSION TESTTHIS IS A COMPRESSION TESTTHIS IS A COMPRESSION TESTTHIS IS A COMPRESSION TESTTHIS IS A COMPRESSION TESTTHIS IS A COMPRESSION TEST";
NSData *theData = [testString dataUsingEncoding:NSUTF8StringEncoding];
size_t src_size = theData.length;
uint8_t *src_buffer = (uint8_t*)[theData bytes];
size_t dst_size = src_size+4096;
uint8_t *dst_buffer = (uint8_t*)malloc(dst_size);
dst_size = compression_encode_buffer(dst_buffer, dst_size, src_buffer, src_size, NULL, COMPRESSION_ZLIB);
NSLog(#"originalsize:%zu compressed:%zu", src_size, dst_size);
NSData *dataData = [NSData dataWithBytes:dst_buffer length:sizeof(dst_buffer)];
NSString *compressedDataBase64String = [dataData base64EncodedStringWithOptions:0];
NSLog(#"Compressed Data %#", compressedDataBase64String);
NSLog(#"START META DATA DECOMPRESSION");
src_size = compression_decode_buffer(src_buffer, src_size, dst_buffer, dst_size, NULL, COMPRESSION_ZLIB);
NSData *decompressed = [[NSData alloc] initWithBytes:src_buffer length:src_size];
NSString *decTestString;
decTestString = [[NSString alloc] initWithData:decompressed encoding:NSASCIIStringEncoding];
NSLog(#"DECOMPRESSED DATA %#", decTestString);
free(dst_buffer);
On the PHP side I used the following function to decompress the data:
function decompressString($compressed_string) {
//NEED RAW GZINFLATE FOR COMPATIBILITY WITH IOS COMPRESSION_ZLIB WITH IETF RFC 1951
$full_string = gzinflate($compressed_string);
return $full_string;
}
When I fetch the source of any web page, no matter the encoding I use, I always end up with &# - characters (such as © or ®) instead of the actual characters themselves. This goes for foreign characters as well (such as åäö in swedish), which I have to parse from "Å" and such).
I'm using
+stringWithContentsOfUrl: encoding: error;
to fetch the source and have tried several different encodings such as NSUTF8StringEncoding and NSASCIIStringEncoding, but nothing seems to affect the end result string.
Any ideas / tips / solution is greatly appreciated! I'd rather not have to implement the entire ASCII table and replace all occurrances of every character... Thanks in advance!

You're misunderstanding the purpose of that encoding: argument. The method needs to convert bytes into characters somehow; the encoding tells it what sequences of bytes describe which characters. You need to make sure the encoding matches that of the resource data.
The entity references are an SGML/XML thing. SGML and XML are not encodings; they are markup language syntaxes. stringWithContentsOfURL:encoding:error: and its cousins do not attempt to parse sequences of characters (syntax) in any way, which is what they would have to do to convert one sequence of characters (an entity reference) into a different one (the entity, in practice meaning single character, that is referenced).
You can convert the entity references to un-escaped characters using the CFXMLCreateStringByUnescapingEntities function. It takes a CFString, which an NSString is (toll-free bridging), and returns a CFString, which is an NSString.
Are you sure they originally are not in Å form? Try to view the source code in a browser first.
That really, really sucks. I wanted to convert it directly and the above solution isn't really a good one, so I just wrote my own ascii-table converter (static) class. Works as it should have worked natively (though I have to fill in the ascii table myself...)
Ideas for optimization? ("ASCII" is a static NSDictionary)
