set a datapointer from addNode(...)?

[tspratt]

If I have created a new node using addNode(), how can I set a datapointer to it?

for example:
var nodeNew = myDatapointer.addNode(sNodeName);
var datapointerNew = ????;

There may be other nodes under myDatapointer with the same node name, so I can't just set the new datapointer to the sNodeName.

This does not seem to work:
sXpath = nodeNew.getNodeAttribute("xpath");

Any suggestions?

Thanks in advance!

You can use the setXPath() of datapointer:


<canvas debug="true">

<debug x="150" height="300" />
<dataset name="myds">
<myrootnode>
<foo bar="1">One</foo>
</myrootnode>
</dataset>

<datapointer name="mydp" xpath="myds:/myrootnode/foo" />

<button>Make XML
<method event="onclick">
mydp.addNode( "myaddednode", "hello", { foo: "bar" } );
mydp.setXPath( "myaddednode" );
Debug.write( mydp.serialize() );

// Write out the contents of the dataset for debugging
var dspointer = canvas.datasets.myds.getPointer();
// debug.write( dspointer.serialize() );
</method>
</button>

</canvas>


Hope this helps!

I can use an index counter and then selectChild and selectNext(index-1) to get my datapointer.

I would still like to know if there is a more "elegant" solution.

Thanks!

because I may have more than one node under mydp with the name 'myaddednode'.

I did find a solution though, see my earlier post.
thanks, Antun.

There isn't a more elegant solution in 1.0.x, however with the Krank release, there will be a far more fluid way of adding nodes.
