Handling XML isn't trivial. It's not one "thing", it's a lot of things.

How I'd suggest doing it is breaking down the tag into multiple lines so you can read "date=Trump Tue 06/19/2012 11:41 AM EDT", then "machine=garg-ln", etc, etc, until the tag is done. xargs can do that easily.

Then you read one by one, splitting on = or < or > into two variables, catch the names you want and ignore the rest.

Code:
#!/bin/sh

# Remove temp file on exit
trap "rm -f /tmp/$$" EXIT

# Little-known incredibly useful property of xargs:  it handles quotes.
# We can use it to transform x='a' y='b c d' into lines like
#
#       x=a
#       y=b c d
#       ...
#
# Ordinary 'while read' loop can handle that easily, splitting on the first =.
xargs -n 1 < file > /tmp/$$

while IFS="=<>" read NAME VALUE
do
        case "$NAME" in
        build)          BUILD="$VALUE"          ;;
        release)        RELEASE="$VALUE"        ;;
        *)                                      ;;
        esac
done < /tmp/$$

echo "${RELEASE}_${BUILD}"

BUILD-JAR-REPOSITORY(1) 					   User Commands					   BUILD-JAR-REPOSITORY(1)

NAME

       build-jar-repository - create a symbolic link to a JAR

SYNOPSIS

       build-jar-repository [OPTION]... DIRECTORY... JAR

DESCRIPTION

       Build a JAR repository in the named directory by copying files or creating symbolic links

OPTIONS

       If no option is specified the default action will be to create symbolic links

       -c, --copy
	      copy files

       -h, --hard
	      create hard links

       -p, --preserve-naming
	      try  to  preserve  the  names  of  the original JAR files (in case of a nested hit the slashes in the path will still be replaced by
	      underscores)

	      using this option makes any future automated repository rebuild impossible, and implies -c unless specified otherwise

       -s, --soft, --symbolic
	      create symbolic links (default)

       --help
	      display help text

EXAMPLES

       build-jar-repository . jndi
	      will create a symbolic link to the JNDI JAR in the current working directory

       build-jar-repository -h /tmp oro
	      will create a hard link to the ORO JAR in /tmp
