How to get namespace of xml

Question

I have this xml:

InputStream is = new ByteArrayInputStream(
        "<data:RobCtiAifoData xmlns:data=\"urn:cz:isvs:rob:schemas:RobDotazyData:v1\" xmlns:reg=\"urn:cz:isvs:reg:schemas:RegTypy:v1\" xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:urn=\"urn:cz:isvs:rob:schemas:RobUnivDotazy:v1\"><data:Aifo a=\"b\">1</data:Aifo><data:VyuzitiPoskytnuti>vyuziti</data:VyuzitiPoskytnuti> </data:RobCtiAifoData>"
                .getBytes());

// InputStream is = new ByteArrayInputStream(xml.getBytes());
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.parse(is);
Node node = document.getDocumentElement();

when wanna get name of element without namespace so I wanna call substring of name of element withou prefix

node.getNodeName() gives me data:VyuzitiPoskytnuti and node.getNamespaceURI() or node.getPrefix() gives me just null. So how I can get prefix of node ?

"when wanna get name of element without namespace so I wanna call substring of name of element withou prefix" - that's completely incomprehensible. — skaffman

Try enabling namespace support:

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();

From the JavaDoc for setNamespaceAware:

Specifies that the parser produced by this code will provide support for XML namespaces. By default the value of this is set to false
