Am writing one small application to parse from XML to JSON object for iphone. can anyone tell me the availability of open source library present to do the parsing usnig objective-c.
There are plenty of open source solutions in objective-c to deal with JSON :
JSONKit : https://github.com/johnezang/JSONKit
SBJson (aka json-framework) : https://github.com/stig/json-framework
YAJL Framework : https://github.com/gabriel/yajl-objc
To deal with xml, you can use the default NSXMLParser class or some other solutions like some code I've posted here (DOM parser) :
NSXMLParser retrieving wrong data from XML tags
You can also check this page which will give you a good overview of available solutions for XML parsing (and an explaination of differences between SAX and DOM parsers) : http://www.raywenderlich.com/553/how-to-chose-the-best-xml-parser-for-your-iphone-project
Well there is a json parser available for objective c on github. Its very simple to use. You may have to write some additional code to provide input to the parser.
I use NSPropertyListSerialization from Apple to turn a Plist XML into a dictionary. Then we just need to find something to go from dictionary to JSON.
The json-framework looks like a nice JSON generator.

I want to create XML string to be sent to server through web-service. How do I do it natively in iPhone? Or do I have to use any third party library?
I was not able to download GDATA for iPhone. Any else available? Or any other way to do it?
Please help,
Thanks in advance.
You can create XML file with StringWithFormat method or Some of XML parser allow write XML as well. Please refer link of Parser for writing XML

You can use JSON parser also....
You may want to refer to SBJSON Framework which is frequently used for objective-C, I have used this framework in may of my iOS Apps.
You may get a reference about it from these links:
https://github.com/stig/json-framework

Example Code: Also here is an example on, How to parse JSON with SBJSON Parser:

I am trying to do following task. I know we can read XML in iOS using a parser, but can we locally update the same XML?
1) Read XML from local resource folder.
2) Update XML. Locally change value of a tag.
Thanks for your help.
If you just need to read the XML you can use the native NSXMLParser. If you need to change the XML you can use TouchXML. You can get a good tutorial on how to use TouchXML here. Also interesting discussion of the various options here.
what are the basic things shall i read to understand how parsing xml in Objective-C works

Xml Parsing
i m using php file for using data in my application,
in this file i post data on the server and if i get the data from the server
then it is in html formate.
so problem is that i have a string with html tags how i use data in that string.
how i extract data from html string.
Use NSXMLParser class. it works for HTML too. There are three useful delegate methods.
If your HTML out put is some simple data - may be you can write some simple NSString parser your self like 'markhunte' mentioned, if you have large complex data in HTML then you have to go for some open source parsers.
Cocoa does not provide HTML parser, Forum discussion claims in some case XML parser itself work for you, but I never go it working for my data.
In my case I had very simple TAG which I had handled using my own parser using NSString.
I have used the code from --> Flatten-html-content-ie-strip-tags-cocoaobjective-c.
There are also examples of its use on SO.
Just use NSScanner, it is great for searching in between tags that are permanent. If you post some page code I help you set up the scanner.
