This method was introduced in the recent 0.3.8 release, so you may need
to upgrade from an older version. 

require 'xml/libxml'
XML::Parser::VERSION
# => "0.3.8"

doc = XML::Document.file('safs/testlog.xml')
set = doc.find('//log_message')
# => <log_message type="start testcase"> [...]
set.length
# => 3
set.first
# => <log_message type="start testcase"> [...]
