Query XML from Java

I am using the javax.xml.xpath to query an XML document. This prgram is working well with many XML. But in One XML where there is namespaces whenever I try to query it using //nodename it does not work. it only works with //* and it returns all the document. Any idea why is that??

If "namespaces" refers to the default namespace then your problem is that XPath 1.0 does not find elements in the default namespace when you ask for them in the normal way by their name. You have to use workarounds likeOtherwise, I believe you have to call the setNamespaceContext() method before using the XPath object to define the namespace URI for each prefix.
