Take an xpath and a file, run the xpath query and output nicely formatted result XML to the terminal or a file

xq

#!/bin/bash

if [ -z "$2" ]; then
	echo "Usage: `basename $0` XPATH FILE"
	exit 1
fi

# For terminal output colourise it too, but for file output just tidy it up
if [ -t 1 ]; then
	xmllint --xpath "$1" $2 | tidy -indent -xml -q | pygmentize -lxml
else
	xmllint --xpath "$1" $2 | tidy -indent -xml -q
fi
