VIM裡格式化XML

把以下的內容加入到vimrc，然後用敲入:PrettyXML即可自動格式化XML。但是這要求xmllint位於你的PATH變數裡。沒有的同學，請安裝包libxml2。

function! DoPrettyXML()
  " save the filetype so we can restore it later
  let l:origft = &ft
  set ft=
  " delete the xml header if it exists. This will
  " permit us to surround the document with fake tags
  " without creating invalid xml.
  1s///e
  " insert fake tags around the entire document.
  " This will permit us to pretty-format excerpts of
  " XML that may contain multiple top-level elements.
  0put =''
  $put =''
  silent %!xmllint --format -
  " xmllint will insert an header. it's easy enough to delete
  " if you don't want it.
  " delete the fake tags
  2d
  $d
  " restore the 'normal' indentation, which is one extra level
  " too deep due to the extra tags we wrapped around the document.
  silent %  " back to home
  1
  " restore the filetype
  exe "set ft=" . l:origft
endfunction
command! PrettyXML call DoPrettyXML()
