Output

After you build and run the application, you should see the following output displayed in the application's console.

Result from selectSingleNode:
Node, <name>:
        <name>new</name>

Results from selectNodes:
Node (0), <name>:
        <name>new</name>
Node (1), <symbol>:
        <symbol>zzzz</symbol>
Node (2), <price>:
        <price xmlns:dt="urn:schemas-microsoft-com:datatypes" dt:dt="number">20.313</price>

Notice that the output above confirms that the selectSingleNode method picks out only the first node from the node set as specified by the XPath expression (//stock[1]/*). The selectNodes method returns the entire set of nodes specified by this XPath expression.

Next, we'll demonstrate how to validate XML.
