As Emile points out, you're clearly doing some other processing between 
that print and the place you're capturing the output.  Presumably this 
is a CGI script or equivalent.  So several other layers of code are 
manipulating that stream before you see it.

Have you added another print immediately after the loop, so you can tell 
that it ended, and that subsequent output is separated from it?   My 
first guess was that you have some character in there that's special to 
html, such as "<", but I don't see such.  In general, you might need to 
escape your data (using & escape sequences), rather than just printing 
it directly to the CGI stream.

Another clue for this type of problem is to look at the "page source" in 
your browser, rather than trust its rendering.  Sometimes the rendering 
gets messed up, especially if the html is not strictly legal.

In Firefox, use  "View -> Page Source" to see the source to the page, 
which should come pretty close to the output of your print statements.

My preference would be to run the script outside of the web-server 
environment, either on a local copy, or by shelling into your server.
