How to redirect stdout output to a new Vim tab?

Question

I\'m editing an XML file in Vim, and then I want to transform it a plain-text file with xsltproc, which by default outputs to a stdout (something like : !xsltproc TXTRULE.XSL %)

Answer 1

I am using the following to view my program outputs (very useful for a makefile with a make run rule)

It opens a new tab next to current one only if one was not already opened before for that purpose:

fu! RedirStdoutNewTabSingle(cmd)
  let a:newt= expand('%:p') . ".out.tmp"
  tabnext
  if expand('%:p') != a:newt
    tabprevious
    exec "tabnew" . a:newt
  else
    exec "%d"
  endif
  exec 'silent r !' . a:cmd
  set nomodified
endfunc

au FileType xml noremap   :call RedirStdoutNewTabSingle("xsltproc")
