您需要从logstash示例读取xml文件，以使用以下logstash配置将其存储到elasticsearch示例。

input {
    file {
        path => "/path/to/your/xml/*.xml"
        start_position => beginning
        sincedb_path => "/dev/null"     
    } 
} 
filter {
    xml {
          source => "message"
          target => "doc"
          store_xml => false
          xpath => [
            "/msg/@time", "time",
            "/msg/@time_norm", "time_norm"
          ]
        }
    }
output {   
    elasticsearch { hosts => ["localhost:9200"] }   
    stdout { codec => rubydebug } 
}

fscrawler还支持读取xml文件。看到了吗https://fscrawler.readthedocs.io/en/latest/admin/fs/local-fs.html#indexing-xml文档
