Now Friends the second file tag is replacing my search data always. Even i am not giving postion="replace".
where i am wrong please give me suggestions.

Answer 1

There is an error in your first file tag code. Most probably:
Wrong file location (catalog/view/theme/shopitout/template/common/header.tpl) .
Or mentioned search code doesn't exist in catalog/view/theme/shopitout/template/common/header.tpl
Proof for the above statements:
Move the second file tag to first - Working.
Or remove the error="abort" parameter form first file tag - 2nd file code Working
if you still can't find the error, then refer the section under the heading - Opencart Vqmod xml file not working?? in https://sankartypo3.wordpress.com/2013/11/25/opencart-vqmod-tutorial/
Have a nice day!!
