Summary:                    Return code in select mode could indicate whether
query matches or not
Description: 
I am trying to use xmlstarlet to test whether XML documents contain certain
elements. Here it would be very helpful, if xmlstarlet could indicate via
its return code whether or not matching elements were found (just like e.g.
grep does). Currently, the return code is always 0 in either case.

$ cat test.xml
<test>
    <item name="foo">bar</item>
</test>

$ xmlstarlet sel -t -c "//item[@name='foo']" test.xml
<item name="foo">bar</item>
$ echo $?
0

$ xmlstarlet sel -t -c "//item[@name='foo-nomatch']" test.xml
$ echo $?
0
