for #1235: Do not exit script when XPATH yields no result

xmllint will return exit code 10 when an XPATH query finds no matches. With the changes in this commit, the script isn't stopped. Instead, it uses an empty value, which is likely to cause the validation checks (further down in the script) to fail.
