How can I store a xml document into xml attribute? I have this code but de output give me escape characters, is right left with these escape characters?
public static void main(String[] args) throws TransformerException,
ParserConfigurationException {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.newDocument();
Element organizations = doc.createElement("ORGANIZATIONS");
doc.appendChild(organizations);
organizations.setAttribute("xml", "<root><first>01</first><second>02</second></root>");
DOMSource domSource = new DOMSource(doc);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
transformer.setOutputProperty(OutputKeys.METHOD, "xml");
transformer.setOutputProperty(OutputKeys.ENCODING, "ISO-8859-1");
StreamResult sr = new StreamResult(new File("test.xml"));
transformer.transform(domSource, sr);
}
output:
<ORGANIZATIONS xml="<root><first>01</first><second>02</second></root>"/>
This is correct. The xml should be escaped when set on an attribute.
If you want to see the plain xml, you have to put it on an element and force the usage of CDATA sections for it:
transformer.setOutputProperty(OutputKeys.CDATA_SECTION_ELEMENTS, "thequalifiednameoftheelement");
CDATA sections cannot be used on attributes... Attributes are not made for being filled with xml documents...

I'm trying to print an XML file colored on console using java, but I have never done this before, and I have no idea how to do that.
This code prints an XML file on console.
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder1;
builder1 = factory.newDocumentBuilder();
Document document;
document = builder1.parse(new File(pathFilename));
TransformerFactory tFactory = TransformerFactory.newInstance();
tFactory.setAttribute("indent-number", new Integer(2));
Transformer transformer = tFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
DOMSource source = new DOMSource(document);
StreamResult result2 = new StreamResult(System.out);
transformer.transform(source, result2);
I would like to print it on console like an editor, for example Notepad++.
Any suggests how to do it?
An example of output on console:
<ControllerMode dataItemId="mode" sequence="286201" timestamp="2019-06-27T11:23:02.641182Z">AUTOMATIC</ControllerMode>
The objective is to read from a xml file and write to a new xml file while preserving newlines. We need the Document object to perform other xml tasks.
Say source.xml looks like this:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<Code><![CDATA[code line1
code line 2
code line 3
code line 4]]></Code>
Now the destination should look the same with the newlines in the code element. But instead it ignores the newlines and makes it one line.
For writing, I am using the method below:
public static void writeFile(Document xml, File writeTo)
{
try
{
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
DOMSource source = new DOMSource(xml);
StreamResult result = new StreamResult(writeTo);
transformer.transform(source, result);
}
catch(TransformerException e)
{
System.out.println("Couldn't write file " + writeTo);
e.printStackTrace();
}
}
The Document xml is obtained using Parse(File) method in DocumentBuilder. Roughly in the lines of:
File file; // a list of files is recursively obtained from a given folder.
DocumentBuilderFactory documentBuilderfactory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = documentBuilderfactory.newDocumentBuilder();
Document xml = builder.parse(file);
The builder.parse seems to be losing the newlines in the CDATA of Code element.
How do we preserve the newlines?
I am new to Java APIs.
When I put your snippets together I get this program:
public class TestNewLine {
public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException, TransformerException {
DocumentBuilderFactory documentBuilderfactory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = documentBuilderfactory.newDocumentBuilder();
Document xml = builder.parse(TestNewLine.class.getResourceAsStream("data.xml"));
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
DOMSource source = new DOMSource(xml);
StreamResult result = new StreamResult(System.out);
transformer.transform(source, result);
}
}
and it prints out:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<Code><![CDATA[code line1
code line 2
code line 3
code line 4]]></Code>
As far as I understood, the newline is preserved already. What output did you expect?
I want to create an xml file with line breaks, looking somewhat like this:
<Instrument currencyId="THB"
disabledCount="0"
hasBeenEnabledOnce="TRUE"
</Instrument>
Using this code I got close but all attributes seems to be end up on the same row:
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.newDocument();
Element rootElement = doc.createElement("Instrument");
doc.appendChild(rootElement);
Instrument.setAttribute("currencyId", "THB");
Instrument.setAttribute("disabledCount", "0");
Instrument.setAttribute("hasBeenEnabledOnce", "TRUE");
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File("C:\\file.xml"));
transformer.transform(source, result);
I get the following result:
<Instrument currencyId="THB" disabledCount="0" hasBeenEnabledOnce="TRUE"
How can I add linebreaks between the attributes??
just a slight notice, I thought that transformer.setOutputProperies could solve the problem, by searching for similar problems I ended up with "OutputKeys.INDENT", "yes", and the indent-amount -> "4". But nothing's changed.
Doesnt matter if I open the file in notepad++ or as a webpage.
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'd like to serialize some simple data model into xml, I've been using the standard java.org.w3c -related code (see below), the indentation is better than no "OutputKeys.INDENT", yet there is one little thing that remains - proper indentation for child elements.
I know that this has been asked before on stackoverflow , yet that configuration did not work for me, this is the code I'm using :
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.newDocument();
doc = addItemsToDocument(doc);
// The addItemsToDocument method adds childElements to the document.
TransformerFactory transformerFactory = TransformerFactory.newInstance();
transformerFactory.setAttribute("indent-number", new Integer(4));
// switching to setAttribute("indent-number", 4); doesn't help
Transformer transformer = transformerFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.METHOD, "xml");
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(outFile);
// outFile is a regular File outFile = new File("some/path/foo.xml");
transformer.transform(source, result);
The output produced is :
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<stuffcontainer>
<stuff description="something" duration="240" title="abc">
<otherstuff />
</stuff>
</stuffcontainer>
Whereas I would want it (for more clarity) like :
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<stuffcontainer>
<stuff description="something" duration="240" title="abc">
<otherstuff />
</stuff>
</stuffcontainer>
I was just wondering if there is a way of doing this, make it properly indented for the child elements.
Thank you in advance !
Happy Easter coding :-) !
If the Transformer implementation you're using is Xalan-J, then you should be able to use:
transformer.setOutputProperty(
"{http://xml.apache.org/xslt}indent-amount", "5");
See also: http://xml.apache.org/xalan-j/usagepatterns.html
import com.sun.org.apache.xml.internal.serializer.OutputPropertiesFactory
transformer.setOutputProperty(OutputPropertiesFactory.S_KEY_INDENT_AMOUNT, "4");
Document doc;
.....
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");
transformer.transform(new DOMSource(doc), new StreamResult(new File("filename.xml")));
transformer.transform(new DOMSource(doc), new StreamResult(System.out));
