XML-JSON Converter Rules

Question

I'm using net.sf.json.xml.XMLSerializer to convert XML documents to JSON. I'm getting two different results for almost two similar XML documents. My code is:

public static void main(String[] args) throws DocumentException {
    String t1="<A><B>aa</B><C><D>Martin Ritt</D> </C></A>";
    String t2="<A><B>aa</B><C><D>Martin Ritt</D></C></A>";
    System.out.println(new XMLSerializer().read(t1).toString());
    System.out.println(new XMLSerializer().read(t2).toString());
}

The first string t1 is converted to:

{"B":"aa","C":["Martin Ritt"]}

while t2 is converted to:

{"B":"aa","C":{"D":"Martin Ritt"}}

That means, in the first case, C is considered an array while in the second case, it is considered an object. The difference between the two XMLs is the space after the closing of the D element. That is, after </D>.

Any idea what is going on here? what is the rule? I'm more interested in how to make it recognize arrays consistently.

The rules are:

Root nodes are discarded, in this case <A>
Element nodes with text node children =>
```
{"Element":"text node"}
```

Element nodes with element children =>

{"Element":{"Element":"text node"} } //t1

Element nodes with mixed children (element + white space) =>
```
{"Element":["text node"]} //t2
```
