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?
<snip/> This nets out to be a JEXL question. It has been asked before a few [1],[2],[3],[4] times. JEXL has no elegant way of doing this (you can store an apostrophe in the state machine's root context and then use it in string concatenation to get by). -Rahul [1] http://www.nabble.com/-scxml--Data%28%29-xpath-and-the-syntax-tf1682372.html [2] http://www.nabble.com/-jexl--How-to-escape-the-Apostrophe-tf1686607.html [3] http://www.nabble.com/-Jelly-JEXL--String-concatenation-tf155102.html [4] http://www.nabble.com/-Jexl--String-Literals-with-Newline-do-not-work-tf4035993.html
