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

The problem, I believe, is that your namespace declaration does not have
a namespace identifier. 
I would expect the namespace to read something like this
This would allow you to use the XPath function, addNamespace, to add the
namespace to the XPath object. Like this:
    xpath.addNamespace("fix", "http://www.fixprotocol.org/FIXML-4-4");
This finds the nodes you are interested in as expected.

     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"
MatDt="2006-02-15" Mult="100" Exch="XCBF" /> 
	- <RptSide Side="1" InptDev="MR" Ccy="USD" PosEfct="O"> 
	<Pty ID="OCC" R="21" /> 
	- <Pty ID="00299" R="1">

	<Pty ID="PJZ" R="2" />

	- <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.
