Using Java XMLSerialiser, how can I insert a string into a node

Question

I am currently using xmlserialiser to output something like the following

<Node1>
   <Child2 attr1="abc">
   <Child3 attr2="xyz">
<Node1>

I have a string like this:

String stringAttribute = "testAttribute='testAttributeValue'";

is there a way using the xmlserialiser to insert the string into the nodes, e.g.

<Node1>
   <Child2 attr1="abc" testAttribute='testAttributeValue'>
   <Child3 attr2="xyz">
<Node1>

Thanks
