[jdom-interest] XPATH using JDOM returns null???

I think the problem is (please someone educate me if I'm wrong) that the
namepsace declaration in the FIXML element is referring to the default
namespace and in JDOM XPATH, there is no such thing as a default
namespace. This is from the JDOM API . . . 
    In XPath, there is no such thing as a 'default namespace'. The empty
prefix always resolves to the empty namespace URI.

     You are absolutely right about the missing end tag. It was an error
of copy & paste. 
    However, what can I do with namespace as this is sent from another
    Any Ideas???

	Assuming your XML snippet has a cut-and-paste error, missing
'Batch' and 'FIXML' end tags, I ran it in my app and the nodeList does
not come back NULL. It does, however, come back empty. If you take out
the namespace declaration in the root node, FIXML, it works as expected.

	I'm pretty sure the problem is that this changes the namespace
of the element, FIXML, and this is why the XPATH does not see it. I
can't tell you what to do to fix it though.

	        I'm parsing an XML file using the following snippet.. 

	        XPath xpath =
	                List nodelist = xpath.selectNodes(doc); 
	                Iterator nd = nodelist.iterator(); 
	                while (nd.hasNext()){ 
	                Element ndele = (Element) nd.next(); 

	        This is the xml snip... 

	        - <FIXML r="20030618" s="20040109" v="4.4" xr="FIA"
xv="1" xmlns="http://www.fixprotocol.org/FIXML-4-4"> 
	- <Batch> 
	- <TrdCaptRpt RptID="29770863" PrevlyRpted="N" LastQty="1"
LastPx="156.4" TrdDt="2005-07-13" TransTyp="0" RptTyp="2" TrdTyp="0"
MtchID="0043025" BizDt="2005-07-13" MtchStat="0"> 

	<Instrmt Sym="VX" ID="VX" Src="8" CFI="FFICSX" MMY="200602"

	- <RptSide Side="1" InptDev="MR" Ccy="USD" PosEfct="O">

	- <Pty ID="00643" R="18"> 
	<Sub ID="C" Typ="26" /> 
	<Pty ID="TM1" R="26" /> 

	        Why does nodelist returns NULL??? 

	        Thanks for your help in advance.
