Based on documentation [Logstash Xpath](https://www.elastic.co/guide/en/logstash/current/plugins-filters-xml.html)

My XML Format :

```
<isomsg direction="outgoing">
	<!-- org.jpos.iso.packager.GenericPackager[cfg/packager/iso87binaryedc.xml] -->
	<field id="0" value="0210"/>
	<field id="3" value="120002"/>
	<field id="4" value="000000165000"/>
	<field id="11" value="000001"/>
	<field id="32" value="1144"/>
</isomsg>

```

My Logstash configuration :

```
xml{
    source => "message"
    xpath => 
      [
        "/isomsg/@direction", "direction",
        "/isomsg/field/@value", " **/isomsg/field/@id**"
      ]
    store_xml => true
    target => "data"
  } 

```

i want to be id = value, how to be done like that ?
