; We have the following XML and wish to find the value of the time attribute where msg = "alert-from".

; <cdr id="4e5d3e7f41bf6201ad81000c29703270" e164="6207">
;     <user>
;         <grp name="wfln" mode="active"/>
;     </user>
;     <event msg="setup-to" time="287069" e164="5034"/>
;     <event msg="alert-from" time="287069" e164="5034"/>

; Show that we have the above XML
