使用Logstash将XML加载到Elasticsearch中

Question

I have tried to create a load process with Logstash from an XML file to Elasticsearch.

Based on the tutorials i have created the following config file:

input {
    file {
        path => [ "D:\data\test\test_invoice.xml" ]
        start_position => "beginning"
        sincedb_path => "nul"
    }
}
filter {
    xml {
        store_xml => "false"
        source => "message"
        #remove_namespaces => "true"
        target => "invoice"
   }
}
output {
    elasticsearch {
        hosts => ["localhost:9200"]
        index => "ofr_invoice"  
    }
    stdout { codec => rubydebug }
}

This is the source XML:

<?xml version="1.0" encoding="UTF-8" ?>
<invoice>
  <invoice_no>125</invoice_no>
  <vendor>abc</vendor>
  <custormer>asdf</custormer>
  <invoice_items>
    <item>
      <item_name>asdf</item_name>
      <item_price>23</item_price>
    </item>
    <item>
      <item_name>qwer</item_name>
      <item_price>45</item_price>
    </item>
  </invoice_items>
</invoice>

When I have executed it with Logstash I got the following result:

It looks OK, but it did not added the record (document) to Elasticsearch. Can anyone tell me why?

I just had the same issue and found the input file path must use forward slashes, so "D:/data/test/test_invoice.xml" instead of "D:\\data\\test\\test_invoice.xml".
