El Capitan breaks gem install as per http://stackoverflow.com/questions/30812777/cannot-install-cocoa-pods-after-uninstalling-results-in-error/30851030#30851030

Use:
  sudo gem install -n /usr/local/bin gem-name

instead.

Obviously you can't parse XML with regex but if you just need to grab some values from a feed quickly...

(?<=tag>).*(?=<\/tag)

should do the trick. Falls over if anything is nested etc.

// compares contents but nor order... which may or may not be what you want
var arr1 = [1,2,3],
  arr2 = [1,2,3];
  
arr1.every(function(item) {
  return arr2.indexOf(item) >= 0;
})
