Struggling to parse XML using Logstash

[Igor_Olikh (Igor)]

I have a lot of logs each one stored in the following xml file:

What I want to achieve:

• create fields in elasticsearch that stores the following:

MainActivityText = "TEST"

My config file:

input {
    file {
        path => "/path/*.xml"
        start_position => "beginning"
        type => "xml"
        sincedb_path => "/dev/null"
        codec => multiline {
            pattern => "<Remarks"
            charset => "ISO8859-8"
            what => "previous"
            negate => "true"
        }
    }
} 

filter {
    xml {
        source => "message"
        store_xml => false
        force_array => false
        target => "Remarks"
        xpath => [
            "/Remarks/MainActivity/text()", "MainActivityText"
        ]
    }
} 

output {
    file
    {
        path => "/path/output.txt"
    }

    elasticsearch
    {
          hosts => ["https://elastic:9200"]
          user => "elastic"
          password => ""
          ssl => true
          ssl_certificate_verification => true
          cacert => "/path/sub_ca.crt"
          index => "test-%{+YYYY.MM}"
    }
}

But the output is not what I expect to get. I just get the whole xml stored in the index.
