But then, I am not able to read the values and store it in a string in a
servlet.
This is what I have done so far.
//read the file into a model
model.read(files, null);
//read the domain
Resource vcard = model.getResource("http://www.wordpress.com/blogs/"; +
files);
The URI must match the resource you are trying to access. Unless "files"
is set to "jhbh" then this won't match your data sample below.
String domain = vcard.getProperty(RDF.subject).getString();
If the input file is the following,
<rdf:RDF
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#";>
<rdf:Description rdf:about="http://www.wordpress.com/blogs/jhbh";>
<rdf:subject>Data structures</rdf:subject>
[Aside: That's a odd way to use rdf:subject, you may mean dcterms:subject.]
<rdf:object></rdf:object>
<rdf:value>hbl</rdf:value>
</rdf:Description>
</rdf:RDF>
I want the String domain to be "Data Structures".
If I put that in a file "temp.rdf" and run:
Model model = FileManager.get().loadModel("temp.rdf");
Resource vcard = model.getResource(
"http://www.wordpress.com/blogs/jhbh";);
String domain = vcard.getProperty(RDF.subject).getString();
System.out.println("Domain = " + domain);
I get:
Domain = Data structures
