Hello Experts, you have been of great help to me when it comes to XSLT. Here is another problem I have while I try to extract the data from RDF/XML files. I don't know how to do that as there are terms like dcterms defined in the XML file. They have mentioned the namespace in the XML file. But, I don't know how to extract the data. The XML file looks something like this..

<?xml version="1.0"?>

And I want to simply extract the data from this file that will look something like this.

<uri>http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=17477949</uri>
<title>A new positive-strand RNA virus with unique genome characteristics from the red imported fire ant, Solenopsis invicta.</title>

I have worked previously with XML files, but I used to exclude the namespaces. I don't know how to extract with namespaces.
There is much more data than this, I am presenting a snapshot of it. And I am going to generalize this code, so the data retrieving is not specific for this file.
Any help is greatly appreciated.

Thank you,
Sammed

Even I got the same error at that line, and I don't know what to do. I am still figuring it out.
Thank you,
