I have difficuties to select a node using XPath. I use an EMMA XML
repesented input:

<emma:emma version="1.0"
   xmlns:emma="http://www.w3.org/2003/04/emma";
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
   xsi:schemaLocation="http://www.w3.org/2003/04/emma
    http://www.w3.org/TR/2007/WD-emma-20070409/emma.xsd";
   xmlns="http://www.example.com/example";>
 <emma:one-of id="r1" emma:start="1087995961542" emma:end="1087995963542">
   <emma:interpretation id="int1" emma:confidence="0.75"
   emma:tokens="flights from boston to denver">
     <origin>Boston</origin>
     <destination>Denver</destination>
   </emma:interpretation>

   <emma:interpretation id="int2" emma:confidence="0.68"
   emma:tokens="flights from austin to denver">
     <origin>Austin</origin>
     <destination>Denver</destination>
   </emma:interpretation>
 </emma:one-of>
</emma:emma>

taken from [1]. This EMMA document is parsed into its DOM and passed into
the engine (attached to the eventdata). Now I'd like to select the <origin>
out of the first interpretation. I tried to use the following statement:

<transition event="emma" xmlns:emma=http://www.w3.org/2003/04/emma
cond="Data(_eventdata.emma,'/emma:emma/emma:one-of/emma:[EMAIL 
PROTECTED]'int1']/origin')
eq 'Boston'" target="twenty" />

I think the XPath itself is correct, but unfortunately the overall statement
is not a valid JEXL statement anymore (as of the ' around "int1"). How
should I select the value of the attribute to make it a valid statement? I
tried to escape using \ , but it did not work.

Any suggestion?
