Usin ToXmlGenerator to serialize a XML file

I need to serialize an XML, the input I want is something like:

 <item id="123">description</item>

I have a serializer that has the following code:

        toXmlGenerator.writeFieldName("item");
        toXmlGenerator.writeStartObject();
        toXmlGenerator.setNextIsAttribute(true);
        toXmlGenerator.writeFieldName("id");
        toXmlGenerator.writeString(element.getId());
        toXmlGenerator.setNextIsAttribute(false);
        toXmlGenerator.writeStringField("",element.getValue());
        toXmlGenerator.writeEndObject();

with the above I get :

  <item id="123">
              <>description</>
            </item>

I've tried different options with toXmlGenerator.writeStringField("",element.getValue());

but nothing works, I tried toXmlGenerator.writeString(element.getValue()); but I get the following error:

com.fasterxml.jackson.databind.JsonMappingException: Can not write String value, expecting field name

Is there a way to do this I am missing?

Solution

  • There is a setNextIsUnwrapped(boolean) method that enables a value output without the node name.

    toXmlGenerator.setNextIsUnwrapped(true);

    It should be placed before writeStringField():

    toXmlGenerator.setNextIsAttribute(false);
toXmlGenerator.setNextIsUnwrapped(true);
toXmlGenerator.writeStringField("", element.getValue());
toXmlGenerator.writeEndObject();
