I receive response in the form of xml from a service,which i parse using nsxmlparser.
In an instance i received an xml where the content is same in two tags.(duplicate item as in below xml)

Xml received:

6000 characters include alphabet,arithmatic & general punctuation marks which would be encoded.

Prob:

In -(void)parser:(NSXMLParser *)parser foundCDATA:(NSData *)CDATABlock
method content in CDATABlock variable is not same in both cases(two tags).in one instance it gives me all 6000 characters and in the other instance it gives me only few may be around 300 characters.The text (6000 characters) is same in both cases which i confirmed.

What could be the reason? Can someone help me may be anybody who faced such issue earlier like me.

Tnx in advance.Plz let me know if something is not clear or not understood.

    thats what cdata is for — it shouldnt be parsed

    CDATA – (Unparsed) Character Data

    src: http://www.w3schools.com/xml/xml_cdata.asp

    PCDATA should be parsed

    you gotta save the block of NSData (may be called N times, so you have to concat that stuff) and -in your case- then parse the result as separate XML
