Usage

python xml-aligner.py <xml document>[.xml]

Hook-up to vim

Clone this to your (preferably to this path):

git clone https://github.com/BurnzZ/xml-aligner.git ~/.vim/bundle/xml-aligner/

and add this to your ~/.vimrc:

function XMLAlign()
    let cursor = getpos('.')
    let l:winview = winsaveview()
    :w
    normal(ggVGd)
    :read !python ~/.vim/bundle/xml-aligner/xml-aligner.py %
    normal(ggdd)
    call setpos('.', cursor)
    call winrestview(l:winview)
endfunction

map <leader>a :call XMLAlign()<CR>

Now press <leader>a and see the magic.

(If you've cloned to a different dir other than ~/.vim/bundles/, make sure you update the path script in the code block above.)

<div id = "main">
