NamedNodeMap attributes = fstElmnt.getAttributes();
for(int a = 0; a< attributes.getLength(); a ++)
{
Node theAttribute = attributes.item(a);
System.out.println(theAttribute.getNodeName()+=+ theAttribute.getNodeValue());
}
如果您使用XPATH检索数据,您可以避免遍历。请阅读本教程。
I am currently parsing XML, but im not quite sure how to parse the "status" attribute of "message":
<message status="test"> <text>sometext</text> <msisdn>stuff</msisdn> </message>
Here is the code, i have cut off everything unnecessary:
NodeList nodeLst = doc.getElementsByTagName("message");
for (int s = 0; s < nodeLst.getLength(); s++) {
Node fstNode = nodeLst.item(s);
if (fstNode.getNodeType() == Node.ELEMENT_NODE) {
Element fstElmnt = (Element) fstNode;
NodeList numberNmElmntLst = fstElmnt
.getElementsByTagName("msisdn");
Element numberNmElmnt = (Element) numberNmElmntLst.item(0);
NodeList numberNm = numberNmElmnt.getChildNodes();
String phoneNumber = ((Node) numberNm.item(0))
.getNodeValue().substring(2);
NodeList txtNmElmntLst = fstElmnt
.getElementsByTagName("text");
Element txtNmElmnt = (Element) txtNmElmntLst.item(0);
NodeList txtNm = txtNmElmnt.getChildNodes();
String text = ((Node) txtNm.item(0)).getNodeValue();
NodeList rcvNmElmntLst = fstElmnt
.getElementsByTagName("received");
Element rcvNmElmnt = (Element) rcvNmElmntLst.item(0);
NodeList rcvNm = rcvNmElmnt.getChildNodes();
String recievedDate = ((Node) rcvNm.item(0)).getNodeValue();
}
}
Can anyone guide me how this is done?
Thanks in advance.
NamedNodeMap attributes = fstElmnt.getAttributes();
for (int a = 0; a < attributes.getLength(); a++)
{
Node theAttribute = attributes.item(a);
System.out.println(theAttribute.getNodeName() + "=" + theAttribute.getNodeValue());
}
You could avoid traversing if you use XPATH to retrieve the data. Read this tutorial.
