And here's the equivalent of this method in sed:

postID="$(echo `cat ./data.xml | sed -n
's/[[:space:]]*<postID>\([[:digit:]]*\)<\/postID>[[:space:]]*/\1/'p)

This expects the exact tags (case changes in the tags would break it), but
handles any superfluous whitespace at the start or end of the line.
