[bdbxml] Replacing and inserting nodes

Hello,

while searching for a free XML database for my diploma thesis, I came across 
bdbxml, which I like a lot. However I am missing a certain behaviour with 
respect to updating and creating nodes in a document.

I am using the Java API and the class in question is of course XmlModify. What 
I need to do is the following:

In a document, locate a specific node and then replace that node with content 
I have as a String. For example I have the following document:

<foo>
	<bar value="1">
		data
	</bar>
	<bar value="2">
		moredata
	</bar>
</foo>

Now I want to replace the node specified by the XPath 
Query /foo/bar[@value="1"] with the following node:

<bar value="15">
	randomdata
</bar>

It seems that there is no method of XmlModify which elegantly handles such a 
situation. It only allows for modification of node contens with 
addUpdateStep. Even the insert methods are not satisfactory for that example, 
because they can't take the whole String as a new node, but require creation 
of an additional node by specifying name and node Type.

Am I missing somethig or do I really need to do something like this:

1) Strip the root from the string to insert
2) insert a new node, with type = element, name = name of the stripped node 
and content of the remaining insert string
3) remove the node I wanted to replace.

I hope my explanations are not too confusing ;-)

Regards,
Sebastian
