Wow! I've been on a lot of forums over the years, but I've never seen
help this good and this fast! Thanks! And thanks to Tim for trying,
but I couldn't get that suggestion to work.
What I actually have now in _vimrc:
" Set filetype to XML if it looks like an XML file and isn't an XHTML
file
" Enable syntax highlighting
" Thanks, A.J.Mechelynck [EMAIL PROTECTED]
autocmd BufReadPost * if getline(1) =~ '<?xml'
\ && &filetype !~ 'html$'
\ | setlocal filetype=xml
\ | syn on
\ | endif

The above would work, to detect the filetype of a file whose filetype
wasn't yet known. Here, the filetype has been detected but you want to
set something else. I suggest adding the following (untested) to your
vimrc:
autocmd BufReadPost * if getline(1) =~ '<?xml\>'
\ && &filetype !~ 'html$'
\ | setlocal filetype=xml | endif
(The middle part is to avoid changing the file type of XHTML files
which have an XML header line.)
Best regards,
Tony.
