XML Einleseproblem

[NiklasP]

Moin alle zusammen,

Fehlerquelle ist dieser Code:

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(new File("C:\\plainfile.xml"));

Ergebnis:
document ist "null".

Ich weiß wirklich nicht was die Ursache ist. Könnte mir bitte jemand weiterhelfen?

Hallo,

versuch mal das, vielleicht passen Deine Importe nicht

import java.io.File;
import java.io.IOException;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;

import org.w3c.dom.Document;
import org.xml.sax.SAXException;

und dann

		DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
		factory.setNamespaceAware(true);
		DocumentBuilder builder = null;
		try {
			builder = factory.newDocumentBuilder();
		} catch (ParserConfigurationException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		try {
			Document document = builder.parse(new File("C:\\plainfile.xml"));
		} catch (SAXException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
