Yes, use

xml { source => "message" target => "theXML" }
split { field => "[theXML][url-group][0][item]" }
split { field => "[theXML][issue-group][0][item]" }
if [theXML][url-group][0][item][id] != [theXML][issue-group][0][item][url][0][ref][0] { drop {} }

mutate { rename => { "[theXML][issue-group][0][item][remediation][0][ref][0]" => "remediation" } }

Of course you will need additional entries in the rename hash to deal with the other fields/
