If I create the org.w3.dom.Node and I put the node
into a context variable foo, how can I access a
node/attribute using XPATH then?
Is something like
condition="foo/specificNode/@specificAttribute eq
'bar'" going to work?

Cool, in any case for some reason Data() is not
working for me when I insert a node using Digester.
Below my code that follows the reccomendations given
by Fasih:
(bSettingsFileContent is a byte array with the
contents of my settings.xml file)
................
Digester digester = new Digester();
digester.push( this );
digester.addRule("datamodel", new
NodeCreateRule());
digester.addSetNext("datamodel",
"addDataToModel");
digester.parse(new ByteArrayInputStream(
bSettingsFileContent ));
...................
public void addDataToModel(Element e) {
Data d = new Data();
d.setNode(e);
this.scxml.getDatamodel().addData(d);
}
The node is inserted in the datamodel as I see while
debugging, however given the settings.xml file:
<datamodel>
<data name="bubp">
<root>
<bubp>
<client clientId="mk1" clientPswd="passmk1"
appType="SP">
the following does not work from my scxml file:
<n:if cond="Data('bubp', 'root/bubp/client/@appType')
eq 'SP'">
It does not work either if I put <bubp> as the root
node in my settings.xml file
