XML インスタンス ドキュメントが与えられた場合:
<foo:A xmlns:foo="http://foo" >
<foo:ListRecords>
<foo:record>
</foo:record>
</foo:ListRecords>
</foo:A>
次のコード:
import java.io.File;
import javax.xml.parsers.*;
import org.w3c.dom.*;
public class FooMain {
public static void main(String args[]) throws Exception {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(new File("record.xml"));
Element rootElement = document.getDocumentElement();
NodeList records1 = rootElement.getElementsByTagNameNS("*", "record");
NodeList records2 = rootElement.getElementsByTagNameNS("http://foo", "record");
NodeList records3 = rootElement.getElementsByTagName("foo:record");
System.out.printf("%d records1 found.\n", records1.getLength());
System.out.printf("%d records2 found.\n", records2.getLength());
System.out.printf("%d records3 found.\n", records3.getLength());
}
}
プリント:
0 records1 found.
0 records2 found.
1 records3 found.
