I am in need to create xml as a string to pass to server. I have managed to convert the data into xml but the encoding format set to utf-8 as default. What i need is i want to set it as utf-16 format. But i haven't got any idea of setting it.
private void XmlCreation(int size,List<DataItem> item) throws ParserConfigurationException, TransformerException
{
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
Document document = documentBuilder.newDocument();
Element rootElement = document.createElement("ArrayOfDataItem");
document.appendChild(rootElement);
for (DataItem in: item)
{
Element subroot = document.createElement("DataItem");
rootElement.appendChild(subroot);
Element em = document.createElement(in.getKey());
em.appendChild(document.createTextNode(in.getValue()));
subroot.appendChild(em);
}
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
java.io.StringWriter sw = new java.io.StringWriter();
DOMSource source = new DOMSource(document);
StreamResult result = new StreamResult(System.out);
transformer.transform(source, result);
String xml = sw.toString();
System.out.println(xml);
}
}
Thanks guys
I haven't tested, but that should do the trick:
transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-16");
This article might help you. Basically, you call setOutputProperty with OutputKeys.ENCODING as key and the desired encoding ("UTF-16") as value.

I have an XML document which has null values in its Value tag (something similar to below)
<ns2:Attribute Name="Store" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri">
<ns2:AttributeValue/>
</ns2:Attribute>
Now, I have to write Java code to modify the values as below.
<ns2:Attribute Name="Store" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri">
<ns2:AttributeValue>ABCDEF</ns2:AttributeValue>
</ns2:Attribute>
I am using DOM parser to parse the XML. I am able to delete the null tag for " but not able to add new values. I am not even sure if we have a direct way to replace or add the values.
Below is the code I am using to remove the child("")
Node aNode = nodeList.item(i);
eElement = (Element) aNode;
eElement.removeChild(eElement.getFirstChild().getNextSibling());
Thanks in advance
Just add data through setTextContent to the element. Sample code is as below:
public static void main(String[] args) throws IOException, SAXException, ParserConfigurationException, TransformerException {
String xml = "<ns2:Attribute Name=\"Store\" NameFormat=\"urn:oasis:names:tc:SAML:2.0:attrname-format:uri\"><ns2:AttributeValue/></ns2:Attribute>";
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(new ByteArrayInputStream(xml.getBytes()));
doc.getDocumentElement().normalize();
NodeList nList = doc.getElementsByTagName("ns2:AttributeValue");
for (int i=0;i<nList.getLength();i++) {
Element elem = (Element)nList.item(i);
elem.setTextContent("Content"+i);
}
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(System.out);
transformer.transform(source, result);
System.out.println(nList.getLength());
}
I'm developing a Java Swing Application, and I want to create objects and save them in a XML file, with the information that a user writes in some text fields.
How can I save that data into a XML file, to form those objects?
You can write your own XML-Writer to write out objects/text to a XML file. For example using DOM
public boolean writeCommonSettingsFromGUI()
{
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.newDocument();
Element rootElement = doc.createElement("NAME_OF_A_ELEMENT");
doc.appendChild(rootElement);
Element xmlInfo = doc.createElement("NAME_OF_ANOTHER_ELEMENT");
xmlInfo.setTextContent("YOUR_CONTENT_TO_SET_FOR_THIS_ELEMENT");
rootElement.appendChild(xmlInfo);
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputPropertiesFactory.S_KEY_INDENT_AMOUNT, "5");
transformer.setOutputProperty(OutputKeys.ENCODING, "ISO-8859-1");
DOMSource source = new DOMSource(doc);
StreamResult result = null;
result = new StreamResult(new File("FILE_PATH_WHERE_TO_SAVE_YOUR_XML"));
transformer.transform(source, result);
return true;
}
use castor framework, you can map your java class to xml file and vice versa
I've a xml document, which will be used as a template
<?xml version="1.0" encoding="UTF-8" standalone="no"?><entry xmlns="http://www.w3.org/2005/Atom" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"><content type="application/xml"><m:properties><d:AccountEnabled>true</d:AccountEnabled><d:DisplayName>SampleAppTestj5</d:DisplayName><d:MailNickname>saTestj5</d:MailNickname><d:Password>Qwerty1234</d:Password><d:UserPrincipalName>saTestj5#identropy.us</d:UserPrincipalName></m:properties></content></entry>
I'm calling it in java using this code where payLoadXML.xml has the above content.
"InputStream is = getClass().getClassLoader().getResourceAsStream("/payLoadXML.xml");"
Now I'm trying to edit the tag values for example changing the from "saTestj5" to "saTestj6" and then converting this entire xml and storing it in xml. Can anyone tell me how can I achieve this? I was told this can be done by using "Node" is it possible?
Use jaxb or sax parsers convert into object by using getter method and change the object and convert back to xml
try this
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = null;
docBuilder = docFactory.newDocumentBuilder();
Document doc = null;
InputStream is = getClass().getClassLoader().getResourceAsStream("/payLoadXML.xml");
doc = docBuilder.parse(is);
Node staff = doc.getElementsByTagName("m:properties").item(0);
Text givenNameValue = doc.createTextNode("abc");
Element givenName = doc.createElement("d:GivenName");
givenName.appendChild(givenNameValue);
staff.appendChild(givenName);
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = null;
transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(doc);
StringWriter writer = new StringWriter();
StreamResult result = new StreamResult(writer);
transformer.transform(source, result);
I have a case like getting an XML and convert the XML elements to document object and getting the element values and attributes which i have been created already
Here is the piece of code i have tried to convert the string to DOM document object
String xmlString = " <r><e>d</e></r>";
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
org.w3c.dom.Document document = builder.parse(new InputSource(new StringReader(xmlString)));
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(document);
StreamResult result = new StreamResult(new StringWriter());
transformer.transform(source, result);
String str1 = result.getWriter().toString();
System.out.println(str1);
But this case is valid for only elements without attributes
what can we do if the
String xmlString = "<element attribname="value" attribname1="value1"> pcdata</element>"
we are using Double quotes for the attribute values"value". The compiler is showing error
Suggest me if there any xml encoder and decoder is there to handle this scenarios ??
you can try
DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader("<root><node1></node1></root>"));
Document doc = db.parse(is);
refer this http://www.java2s.com/Code/Java/XML/ParseanXMLstringUsingDOMandaStringReader.htm
Either escape the double quotes with \
String xmlString = "<element attribname=\"value\" attribname1=\"value1\"> pcdata</element>"
or use single quotes instead
String xmlString = "<element attribname='value' attribname1='value1'> pcdata</element>"
DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document document = db.parse(new ByteArrayInputStream(xmlString.getBytes("UTF-8"))); //remove the parameter UTF-8 if you don't want to specify the Encoding type.
this works well for me even though the XML structure is complex.
And please make sure your xmlString is valid for XML, notice the escape character should be added "\" at the front.
The main problem might not come from the attributes.
public static void main(String[] args) {
final String xmlStr = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>\n"+
"<Emp id=\"1\"><name>Pankaj</name><age>25</age>\n"+
"<role>Developer</role><gen>Male</gen></Emp>";
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder;
try
{
builder = factory.newDocumentBuilder();
Document doc = builder.parse( new InputSource( new StringReader( xmlStr )) );
} catch (Exception e) {
e.printStackTrace();
}
}
Has anybody seen anything like this before? I will post the xsl and xml if I have to but I would have to take sensitive data out of it.
The code used to handle the XSL transformation:
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(new DOMSource( xslDoc));
DOMResult domresult = new DOMResult();
transformer.transform(new DOMSource(xmlDoc), domresult);
Node node = domresult.getNode();
resultDoc = (Document) node;
Never seen it going blank. For JAVA6 (also compatible with 1.5), I have the following code that is working, the difference seems to on TransformerFactory used.
private DocumentBuilderFactory factory;
private DocumentBuilder builder;
private Transformer xformer;
//presetup - needs to be done just once
factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
builder = factory.newDocumentBuilder();
xformer = TransformerFactory.newInstance().newTransformer();
//Transform the file
Source source = new DOMSource(doc);
String oFileName = "output.xml";
File oFile = new File(outputDirectory + "/" + oFileName);
Result result = new StreamResult(oFile);
xformer.transform(source, result);
Does this correct your issue?
