Your code only shows the opening of the file, but not how you actually read from the file and also not how you output the content. Please post the relevant code, preferrably within <code>...</code> tags, so that we can try to replicate your situation.

If you are outputting data that is to be interpreted as HTML, note that you will need to escape the chevrons. See for example HTML::Entities on how to properly escape ><& (and some more).
