Elasticsearch获取字段的值-Java API

Question

Hi guys i'm new to elasticsearch and im trying to process the error im currently getting here. So i just want a single field value for example "xmldata" which i added in a earlier process in the xml file. The xml is formatted to json an succesfully loaded to my ES-Server, the json file is correct.

Here my code:

        Client client = TransportClient.builder().build()
            .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));

    // GetResponse response = client.prepareGet("store", "xml",
    // xsdid).setFields("xmldata").execute().actionGet();
    GetResponse response = client.prepareGet().setIndex("store").setType("xml").setId(xsdid).setFields("xml").execute().actionGet();

    String id = (String) response.getSource().get("xml");

i'm getting follow Error:

MapperParsingException[failed to parse]; nested: IllegalArgumentException[Malformed content, found extra data after parsing: START_OBJECT];

My XML looks like this if you need it:

    <?xml version="1.0" encoding="UTF-8"?><XmlDoc><FunctionResult result="success"><Message>Processed Correct!</Message></FunctionResult>

Client client = TransportClient.builder().build().addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));

    GetResponse getResponse = client.prepareGet("database", "xsd", xsdid).execute().actionGet();

    Map<String, Object> source = getResponse.getSource();

Like this i'm getting the full json-file back

but is there a better way just to get the single one (xmldata)?
