The problem

curling through web services can be tedious without some basic pretty printing. Let's see how easy it is to create aliases for pretty printing json/xml formats with Python's pygments library and xmllint/jsonp.

The Solution

alias xml='xmllint --format - | pygmentize -l xml -O encoding=utf8'
alias json='jsonpp | pygmentize -l json -O encoding=utf8''

Then just curl http://wservice.viabicing.cat/getstations.php\?v\=1 | xml or curl https://b83c5a5e-d575fbfbad2f.my.apitools.com | json to get nice XML/JSON output.
