Attached is a sample XML file from which I need to extract data. I am using the DOM document approach, learning from the DOMCount sample code. I am able to extract the data from the "Identification", "Grid", "Solution", and "Results" nodes. I am also able to list the Names of the three nodes called "Panel" using the getElementsByTagName method from the document root. Where I am running into trouble is extracting the attribute data for each element called "Node" [sorry about the use of "Node" here for the corners of an aircraft fuselage panel] for a particular Panel. What should be the approach here, please? (I tried using getElementsByTagName from a "Panel" node - did not work; I tried descending down the subtree using child nodes - could not make it work; I thought about using filters - did not know where/how to start). Can you point me to sample code for the approach you would recommend, please?
