Bash stuff I should've learned before

I wanted to grab some variables from an xml and parse them into environment variables.

After some googling around, I found my answer:

1. Use xmlstarlet to pull the name/value pairs
2. Then use sed to combine them into "name=value" format
3. Then use a while loop with process substitution

It ended up being something like

#!/bin/bash

while read -r line; do
  # do some stuff to parse the line
  # ...
  printf -v $varname "$varval"
  export $varname
done <<< "$(xmlstarlet sel -t -m "[xml selections here]" -v . -n <[xml file]  | sed 'N;s/\n/=/')"

Yay so cool.
