Parser to extract URIs from RDF/XML web page for my Web-Crawler in Java

[ViRoX]

I am building a web Crawler for Linked Data. I have differentiated between HTML and RDF/XML page by following code:\[code\]public static int checktype(URL url) throws IOException{String contentType = ((HttpURLConnection) url.openConnection()).getContentType();System.out.println("Website is read"); int t=0;if("text/html".equals(contentType)) {t=0;}else if("application/rdf+xml".equals(contentType)) {t=1;}System.out.println(contentType);return t;\[/code\]}Now I want to parse a web page with RDF/XML data to extract all URIs from that page. I am able to find HTML parsers but not for LINked Data. Please help me further
