Query results issues
Note that selecting an XML element with no text content will always return an empty string.
As shown in the following example, the selected element, Features, is a wrapper element. The Query will return an XML element "Features" but with no content (XML database may do a value concatenation in this case).
<Product>
<Features>
<Colors>
<Color>Blue</Color>
<Color>Red</Color>
</Colors>
</Features>
</Product>
