SimpleXML Element＆＃39; x＆＃39;已经与＆＃39; x＆＃39;

Question

我正在尝试处理一些重新定义为孩子的XML。我的意思是我有以下XML片段：

<ns4:Warning>
    <ns4:Symptom DTCList="2~3~600E18~C2797~NONE" sortOrder="5460">
        <ns4:Symptom>Symptom description ...</ns4:Symptom>
    </ns4:Symptom>
</<ns4:Warning>

我从SimpleXML收到以下错误：

Element 'Symptom' is already used with @org.simpleframework.xml.Element(name=Symptom, data=false, type=void, required=false) on field 'symptom' com.foo.response.xml.SymptomNS4 com.foo.response.xml.Warning.symptom at line 1

警告类：

@Root(name = "Warning")
public class Warning {
    @Element(name = "Symptom") SymptomNS4 symptom;
}

SymptomNS4课程：

@Root(name = "Symptom")
public class SymptomNS4 {
    @Attribute(name = "DTCList") String dtcList;
    @Attribute(name = "sortOrder") String sortOrder;
    @Element(name = "Symptom") String symptom;
}

显然，我采取的方法不起作用。你如何在SimpleXML中模拟这块XML？
