XStream Element contains TextNode and Element

Question

I am using xstream to parse XML and everything goes well while.... there is a situation that xstream seem can't handle it.

There's one tag named "", but in different xml file, it can contain text node or other XML tag.

It can be like this:

XML File 1:
<Spec> text Node Here </Spec>

XML File 2:
<Spec Id="1">
    <Tag1>value</Tag1>
    <Tag2>value</Tag2>
</Spec>

And In Spec class, I have this code...

@XStreamAlias("Spec")
@XStreamConverter(value = ToAttributedValueConverter.class, strings = { "spec" })   //when Text Node
public class Spec
{
    String spec;        // text Node

    @XStreamAlias("Id")
    @XStreamAsAttribute
    String id;

    @XStreamAlias("Tag1")
    String tag1;

    @XStreamAlias("Tag2")
    String tag2;
    // getter and setter...
}

in case of XML File 1, it works fine, but in case of XML File 2, values of fields "tag1" and "tag2" are null, and value of field "spec" is like : "\n\t\t"

What can I do to handle these two files? Thanks in advance!

Yes I've solved this problem... but not in a good way.

split the Spec class into 2 classes: one for text node and the other for xml elements.

and while parsing different xml file, using xstream.alias("Spec", Spec1.class); and xstream.alias("Spec", Spec2.class); to switch two different format.
