Hi anshumangoyal,

I have had minimal experience with xml, however, do any of these questions help locate the issue;

• Given the match for 'NA' is case insensitive,
  • Are all the rows of different column lengths?
  • Are the 'NA's entered by hand?
  • Could a different approach to the match help, such as matching for m/^[cqi|nom|sim|etc...]/?
• What kind of value is $Searchkey?
  • Does $Searchkey require the final "/" to match the xpath element?
  • Is $Searchkey a regex? would it need to be compiled as "qr/".$Searchkey."/"?
  • if so would be beter to compile with a) single quotes and b) non path delimiters eg 'qr#'.$Searchkey.'#'
  • have you tried printing out the $Searchkey values to see what is being matched?

I hope these prompts can help towards debugging.

My hunch, is that the match cuts off after the first element as you are using the forward slash as your match delimiter. By using a different delimiter for the matching may resolve this because paths are delimited by the forward slashes the same as are used to delimit matches.
