Hi there!

I am trying to evaluate an XPath expression using variables, like this:
"$foo/Street" -- where $foo is a variable with an Address element,
containing a Street element:

        <Address>
            <ID>Fakturering</ID>
            <Street>Holsteinsgade</Street>
            <HouseNumber>63</HouseNumber>
            <CityName>København Ø.</CityName>
            <PostalZone>2100</PostalZone>
            <Country>
                <Code>DK</Code>
            </Country>
        </Address>

While evaluating the simple "$foo" expression works fine, the
"$foo/Street" expression throws an exception with the message "Unknown
error in XPath".

Any help, hints or references to documentation is appreciated. Thank you
for your time. I hope to be able to help you out some day.

The attached source code and XML file illustrates this problem if you
like to try it out your self. I used a JDK 1.5.0_08.
