Thanks for ur Reply,.

Answer 1

wrong string comparison

if (lblTitle.text==@"Arts & Entertainment")

it should be like this - try this it must work & let me know.

if (lblTitle.text isEqualToString:@"Arts & Entertainment")

I am also having some issues in my search class, i am using JSON url.

Answer 2

1. Where is the Parsing URL, what are the fields in the xml.

2. Check your parsing url in ur local browser by manual append method using query string ,working or not.

3. check by trace path, use console log for print the URL.

4. Check if u are using localhost url in ur program somewhere else.

5. Check your delegate for search class.

use this link for your reference.
