New to XML, trying to learn to get data out of XML file. File reads like
[CODE]
- <chart-config>
- <chart>
<dataflow>Row</dataflow>
<starting-col>2</starting-col>
<starting-row>25</starting-row>
<chart-name>lineChart</chart-name>
</chart>
</chart-config>
[CODE]
Trying to figure out how to pull the values of the XML file out. I am trying to use DOM, but NodeValue always comes out null.

The JavaDocs for org.w3c.dom.Node have a marvelous table sumarizing what you get from getNodeName and getNodeValue for various subclasses of Node.
The key thing you need to realize is that in XML like this:
<dataflow>Row</dataflow>
You have an Element Node named dataflow that contains a Text Node which has the value "Row". The result of getNodeValue() on the Element Node is null.
You have to get the child node to get the Text Node.

It is sorta covered in the JavaRanch Style Guide.
