Re: [Simple-support] Parsing an XML containing Java keyword

[Mishra, D. <c_d...@qu...>]

Thanks for the reply Niall ! Let me rephrase my query...

I need to parse an XML like this :
<myEnum>new</myEnum>

My Java bean is this :
public enum MyEnum {

    @Element(name="new")
    NEW("new"),
    OLD("old");

     private final String value;

     MyEnum(String v)
     {
         value = v;
     }
}

My Java code for parsing is this :
public static void main(String[] args) throws Exception {
        Serializer serializer = new Persister();
        File source = new File("myenum.xml");
        MyEnum example=null;
        try{
        example = serializer.read(MyEnum.class, source);
        }
        catch(IllegalArgumentException e)
        {
            e.printStackTrace();
        }
}

The exception I get is this :
java.lang.IllegalArgumentException: No enum const class MyEnum.new
    at java.lang.Enum.valueOf(Unknown Source)
    at org.simpleframework.xml.transform.EnumTransform.read(EnumTransform.java:58)
    at org.simpleframework.xml.transform.EnumTransform.read(EnumTransform.java:29)
    at org.simpleframework.xml.transform.Transformer.read(Transformer.java:104)


How should I go around this ? Can you please provide some more pointers than those mentioned in your last reply.

Thanks !

I am not sure what your trying to do here, but what you should do is implement your own EnumTransform and plug it in to the Persister using a Matcher.

Hi,
We are working on an Android project which consumes some web-services not in our control. These web-services respond with an XML, with text value as "new". Example :
<myEnum>new</myEnum>

As per the XSD, we need a Java enum to code for this.
public enum MyEnum {
    @Element(name="new")
    new("new"),       // but we can't use 'new' here as it's a Java keyword
    old("old");
}

SimpleXml seems to use valueOf() - which we can't overrride and hence we are unable to proceed. Please suggest some alternatives. I got this working after changing SimpleXml source code, but this is not acceptable to my team !


PS : The exception if it helps (when I use NEW instead of new)
java.lang.IllegalArgumentException: No enum const class pojos2.MyEnum.new
    at java.lang.Enum.valueOf(Unknown Source)
    at org.simpleframework.xml.transform.EnumTransform.read(EnumTransform.java:58)


Thanks,
Deepak
