Trying to parse XML-logs

Elastic Stack Logstash
2

I would start with something like this:

input { 
    file { 
        path => "/somepath/somefile.xml" 
        codec => multiline { 
            pattern => "randomString" 
            negate => true 
            what => "previous" 
            auto_flush_interval => 2 
        }
        start_position => "beginning" 
        sincedb_path => "/dev/null" 
    } 
}
output { stdout { codec => rubydebug } }
filter {
    xml { 
        source => "message" 
        target => "theXML"
        store_xml => true 
    }
}
