Nifi:How to remove xml tag from xml response data?

[#1]

I want to replace <?xml version="1.0" encoding="utf-8"?> tag by <DailyData></DailyDate>

I used to replace text nifi processor with this search value:^<[^>]+>(.*)<\/\w+>$ and I put replace value like this in replace value <DailyData>$1</DailyData> but I got error like this inside xml file:

This page contains the following errors:

error on line 1 at column 4081: XML declaration allowed only at the start of the document Below is a rendering of the page up to the first error.

what should I change?
