When you posted this the first time, I thought it was a C++ issue,
because the subject appeared to be using C++ syntax.
I can tell you what's going wrong: XObject.str() produces the string
value of the result tree fragment in the XPath sense - that is, it's
equivalent to evaluating the XPath expression "string($testvar)". In this
case, the result is the empty string.
