XSH Scripting Language

• Inspired by Bash and Perl

• The usual high-level features:

  • conditional statements (if, unless)
  • loops (while, foreach, iterate) with full flow control (last, next, prev, redo)
  • exception handling (try/catch/throw)

• Over 100 pre-defined commands (some take flags/parameters)

• User definable commands

• No expression language of its own – instead XPath and Perl expressions are used to specify arguments

• Global, local, and lexically scoped variables (as in Perl)
