[prepare2. xpath]
Usage:
/usr/bin/xpath [options] -e query [-e query...] [filename...]

	If no filenams are given, supply XML on STDIN.
	You must provide at least one query. Each supplementary
	query is done in order, the previous query giving the
	context of the next one.

	Options:

	-q		quiet. Only output the resulting PATH
	-s suffix	use suffix instead of linefeed.
	-p postfix	use prefix instead of nothing.
