I have tested this with the XHTML document below:
---
<cfg:command name="pick-this">
<cfg:macro>
<cfg:sequence>
<cfg:get expression="//li"/>
<cfg:command name="pick" parameter="Choose false %_"/>
<cfg:command name="alert" parameter="%_"/>
</cfg:sequence>
</cfg:macro>
</cfg:command>
<binding>
<keyPressed code="F5" />
<command name="pick-this" />
</binding>

(Specify expression such as "//foo" in the expression attribute, not in
the context attribute. The default context is the document, which is
fine for absolute expressions.)

It works as expected. It displays a list containing just A (and not A, B
and C).
Explanation:
* //li returns a node-set.
* a node-set is converted to a string by returning the string value of
the node of the node-set which is first in document order.
To make this work, you need to use a ``join function'': join(//li, ' ').
Unfortunately, there is no standard join function in XPath, so you need
to write it yourself in Java.
An alternative is to use a process command (cached, with no feedback) as
the first item of your macro-command. See
http://www.xmlmind.com/xmleditor/_distrib/docs/commands/ch05.html
This process command will write a text file containing quoted string
which will be loaded using a <read> process command item.

Yes, this should be possible because you can use XPath expressions to
parameterize the combo-box but, here too, a ``join function'' is needed.

PS: With XXE, almost everything is possible if you write it in Java.
