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"?>

  </dcterms:URI>

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>

<PubmedID>PMID: 17477949</PubmedID>

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

Hello experts, any idea on this please?

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,
