I want to read DOM document using Stax stream readers and write it using Stax stream writers. I want to modify xml file and change some element values I want the cursor to point at a certain element in xml file befor building dom tree I wrote this code but the xml file did not modified can anybody help me ?
FileInputStream input = new FileInputStream("cv.xml"); XMLStreamReader reader = XMLInputFactory.newInstance().createXMLStreamReader(input); BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
//-*-*- get new entries from input stream
System.out.println("<< CV >>\n -> Modify the first reference\n ** Modify The Name **");
System.out.print(" Enter degree : ");
String degree = in.readLine();
System.out.print(" Enter first name : ");
String fName = in.readLine();
System.out.print(" Enter last name : ");
String lName = in.readLine();
System.out.println(" ** Modify The Address ** ");
System.out.print(" Enter new city : ");
String newCity = in.readLine();
System.out.print(" Enter new country : ");
String newCountry = in.readLine();
//-*-*- let the reader point at the first "reference" element
int eventType;
boolean ref = false, fname = false;
while (reader.hasNext()) {
eventType = reader.next();
switch (eventType) {
case XMLEvent.START_ELEMENT:
if (reader.getLocalName().equalsIgnoreCase("references"))
return;
}
}
//-*-*- build DOM trees using Stax stream reader
Document doc = new DOMConverter().buildDocument(reader);
reader.close();
input.close();
//-*-*- start modification
Element fir开发者_运维知识库stRef = (Element)doc.getElementsByTagName("reference").item(0);
NodeList name = (NodeList)firstRef.getElementsByTagName("name");
//-*-*- modify the degree (Dr. , Eng. , Dev. ,etc)
Attr att = (Attr)name.item(0).getAttributes().item(0);
((Node)att).setNodeValue(degree);
//-*-*- modify first name
NodeList firstName = (NodeList)firstRef.getElementsByTagName("fname");
NodeList firstNameChilds = (NodeList)firstName.item(0).getChildNodes();
((Node)firstNameChilds.item(0)).setNodeValue(fName);
//-*-*- modify last name
NodeList lastName = (NodeList)firstRef.getElementsByTagName("lname");
NodeList lastNameChilds = (NodeList)lastName.item(0).getChildNodes();
((Node)lastNameChilds.item(0)).setNodeValue(lName);
//-*-*- modify city
NodeList city = (NodeList)firstRef.getElementsByTagName("city");
NodeList cityChilds = (NodeList)city.item(0).getChildNodes();
((Node)cityChilds.item(0)).setNodeValue(newCity);
//-*-*- modify country
NodeList country = (NodeList)firstRef.getElementsByTagName("country");
NodeList countryChilds = (NodeList)country.item(0).getChildNodes();
((Node)countryChilds.item(0)).setNodeValue(newCountry);
//-*-*- write DOM document
FileOutputStream out = new FileOutputStream("cv.xml");
XMLStreamWriter sw = XMLOutputFactory.newInstance().createXMLStreamWriter(out);
new DOMConverter().writeDocument(doc, sw);
sw.close();
out.close();
It's probably because you are returning when you find the "references" element. Maybe break
is what you meant.
