Followup:
Broadly, this is a usage error. See
http://commons.apache.org/jxpath/users-guide.html#Map_Element_Access

Often you will need to use the alternative syntax for
accessing Map elements:
String homeZipCode = (String)context.
getValue("[EMAIL PROTECTED]'home']/zipCode");
Unlike a child name in XPath, the value of the "name"
attribute does not have to be a properly formed
identifier. Also, in this case the key can be an
expression, e.g. a variable.

I will leave the bug report open, however, because the
fact that selectSingleNode() behaved the way you
wanted it to is the actual bug (as I suspected might
be the case). :)
