Working great for me with following log stash changes

input {
beats {
port => 5044
}
}
filter {
xml {
store_xml => "false"
source => "message"
remove_namespaces => "true"

xpath =>[
"/propertyAvailability/hotelRates/hotel/bookingChannel/ratePlan/roomDetails/hhBedTypes/hhBedType/@hhBedType","hhBedType"
]
}
}

output {
elasticsearch {
hosts => ["http://localhost:9200"]
index => "10jun2"
}
}
