Problem in xml code

[Luckyman]

Hai everybody!
I have a problem with the xml code. I use sitemap.xml for my site. But when the url was opened in the browser, it says

XML Parsing Error: xml declaration not at start of external entity
Line Number 2, Column 1:
<?xml version="1.0" encoding="UTF-8"?>
^

What shall I do to rectify the defect? Please advice me

I've never tried XML before, but the error makes it look like that should be on Line 1 instead of Line 2.

Make sure that declaration is before any other whitespace or code.

here is the layout example of most of my sitemap xml feeds,

<?xml version="1.0" encoding="UTF-8"?>
<urlset
      xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9
