I know this isn't really what XPath is for but if I have a HashMap of XPath expressions to values how would I go about building an XML document. I've found dom-4j's DocumentHelper.makeElement(branch, xpath) except it is incapable of creating attributes or indexing. Surely a library exists that can do this?

Map xMap = new HashMap();

xMap.put("root/entity/@att", "fooattrib");
xMap.put("root/array[0]/ele/@att", "barattrib");
xMap.put("root/array[0]/ele", "barelement");
xMap.put("root/array[1]/ele", "zoobelement");

would result in:

<root>
<entity att="fooattrib"/>
<array><ele att="barattrib">barelement</ele></array>
<array><ele>zoobelement</ele></array>
</root>
