How do I write this document to the local filesystem?
public void docToFile(org.w3c.dom.Document document, URI path) throws Exception {
File file = new File(path);
}
I need to iterate the document, or might there be a "to xml/html/string" method? I was looking at:
document.getXmlEncoding();
Not quite what I'm after -- but something like that. Looking for the String representation and then to write that to file like:
Path file = ...;
byte[] buf = ...;
Files.write(file, buf);
https://docs.oracle.com/javase/tutorial/essential/io/file.html
I would use a transformer class to convert the DOM content to an xml file, something like below:
Document doc =...
// write the content into xml file
DOMSource source = new DOMSource(doc);
FileWriter writer = new FileWriter(new File("/tmp/output.xml"));
StreamResult result = new StreamResult(writer);
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.transform(source, result);
I hope this ends up working for you!

I have a process of XML transform in which I am writing the output transformed XML to a file. But instead of storing it in a file I want to store it in a string variable. I have created a string variable, please advise how can I store the generated XML in a string variable (msgxml instead of writing a file).
String msgxml;
System.setProperty("javax.xml.transform.TransformerFactory",
"org.apache.xalan.processor.TransformerFactoryImpl");
FileInputStream xml = new FileInputStream(xmlInput);
FileInputStream xsl = new FileInputStream(xslInput);
FileOutputStream os = new FileOutputStream(outputXmlFile);
TransformerFactory tFactory = TransformerFactory.newInstance();
// Use the TransformerFactory to process the stylesheet source and produce a Transformer
StreamSource styleSource = new StreamSource(xsl);
Transformer transformer = tFactory.newTransformer(styleSource);
StreamSource xmlSource = new StreamSource(xml);
StreamResult result = new StreamResult(os);
//here we are storing it in a file ,
try {
transformer.transform(xmlSource, result);
} catch (TransformerException e) {
e.printStackTrace();
}
One way is to use an ByteArrayOutputStream instead of a FileOutputStream:
ByteArrayOutputStream baos = new ByteArrayOutputStream();
TransformerFactory tFactory = TransformerFactory.newInstance();
...
StreamSource xmlSource = new StreamSource(xml);
StreamResult result = new StreamResult(baos); // write to the byte array stream
//here we are storing it in a file ,
try {
transformer.transform(xmlSource, result);
}
...
msgxml = baos.toString("UTF-8"); // get contents of stream using UTF-8 encoding
Another solution is to use a java.io.StringWriter:
StringWriter stringWriter = new StringWriter();
StreamResult result = new StreamResult(stringWriter);
...
msgxml = stringWriter.toString();
I'm trying to create a PDF document with Apache Library FOP. It works well but I have to create a temp file to store an intermediate file (test.fop).
Here is my function:
#RequestMapping(value = "/pdf")
public void showPdfReport(OutputStream pdfOutStream) throws Exception
{
// Setup
FopFactory fopFactory = FopFactory.newInstance();
TransformerFactory factory = TransformerFactory.newInstance();
// Transformation XML to XML-FO
StreamSource xsltSource = new StreamSource(servletContext.getResourceAsStream("resources/xsl/pdfTemplate.fo"));
Transformer transformer = factory.newTransformer(xsltSource);
OutputStream fopOutStream = new BufferedOutputStream(new FileOutputStream(new File(
"C:/Temp/tests/test.fop")));
StreamSource xmlSource = new StreamSource(servletContext.getResourceAsStream("resources/xsl/test.xml"));
StreamResult fopResult = new StreamResult(fopOutStream);
transformer.transform(xmlSource, fopResult);
// Transformation XSL-FO to PDF
Source fopSrc = new StreamSource(new File("C:/Temp/tests/test.fop"));
Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, pdfOutStream);
Result res = new SAXResult(fop.getDefaultHandler());
transformer = factory.newTransformer();
transformer.transform(fopSrc, res);
}
Is it possible to store test.fop in a stream or any buffer instead of a file?
There's an example on the FOP website that explains exactly this. The SAX events emitted from the XSLT transformation are directly fed into FOP. No buffering in a file or in memory.
Sure, you can pass any Reader or InputStream to the StreamSource constructor
You could use StringReader or ByteArrayInputStream for example.
i would like to append a new tag with some attributes with those values in to xml file and save that xml file through my application.i have written a method for append a new tag as child to xml file which is available in sdcard of android emulator.the following method for append a new tag as follows
public void appendTag(){
try{
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document doc = docBuilder.parse (new File("/sdcard/sample.xml"));
Node node = doc.getElementsByTagName("earth").item(0);
//append a new node to earth
Element newelmnt = doc.createElement("new");
newelmnt.appendChild(doc.createTextNode("this is a text"));
node.appendChild(newelmnt);
}
catch (Exception e) {
e.printStackTrace();
}
}
after execution of this method i can't able to find a new tag in xml file.
could please any one help on how to append new tag as child in xml file and how save the modification?
if i uses TransformerFactory i am getting error as
ERROR/AndroidRuntime(13479): java.lang.VerifyError: com.sample.xmlapp.DOMClass
i have used as follows
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File("/sdcard/sample.xml"));
transformer.transform(source, result);
Your in memory document will be changed, but you will need to write it to a file again.
Try adding this for writing the document to the file again:
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File("/sdcard/sample.xml"));
transformer.transform(source, result);
I am using NekoHTML to parse contents of some HTML file..
Everything goes okay except for extracting the contents of the Document Object to some string.
I've tried uses
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(writer);
transformer.transform(source, result);
But nothing appears returned.
The problem where in Oracle App server 10.3.1.4 http://m-hewedy.blogspot.com/2011/04/oracle-application-server-overrides.html
Posible solution:
//this nekohtml
DOMParser parser = new DOMParser();
parser.parse(archivo);
//this xerces
OutputFormat format = new OutputFormat(parser.getDocument());
format.setIndenting(true);
//print xml for console
//XMLSerializer serializer = new XMLSerializer(System.out, format);
//save xml in string var
OutputStream outputStream = new ByteArrayOutputStream();
XMLSerializer serializer = new XMLSerializer(outputStream, format);
//process
serializer.serialize(parser.getDocument());
String xmlText = outputStream.toString();
System.out.println(xmlText);
//to generate a file output use fileoutputstream instead of system.out
//XMLSerializer serializer = new XMLSerializer(new FileOutputStream(new File("book.xml")), format);

See e) Serialize DOM to FileOutputStream to generate the xml file "book.xml" .
Currently, I have a String object that contains XML elements:
String carsInGarage = garage.getCars();
I now want to pass this String as an input/stream source (or some kind of source), but am unsure which one to choose and how to implement it.
Most of the solutions I have looked at import the package: javax.xml.transform and accept a XML file (stylerXML.xml) and output to a HTML file (outputFile.html) (See code below).
try
{
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(new StreamSource("styler.xsl"));
transformer.transform(new StreamSource("stylerXML.xml"), new StreamResult(new FileOutputStream("outputFile.html")));
}
catch (Exception e)
{
e.printStackTrace();
}
I want to accept a String object and output (using XSL) to a element within an existing JSP page. I just don't know how to implement this, even having looked at the code above.
Can someone please advise/assist. I have searched high and low for a solution, but I just can't pull anything out.
Use a StringReader and a StringWriter:
try {
StringReader reader = new StringReader("<xml>blabla</xml>");
StringWriter writer = new StringWriter();
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(
new javax.xml.transform.stream.StreamSource("styler.xsl"));
transformer.transform(
new javax.xml.transform.stream.StreamSource(reader),
new javax.xml.transform.stream.StreamResult(writer));
String result = writer.toString();
} catch (Exception e) {
e.printStackTrace();
}
If at some point you want the source to contain more than just a single string, or you don't want to generate the XML wrapper element manually, create a DOM document that contains your source and pass it to the transformer using a DOMSource.
This worked for me.
String str = "<my>xml</my>"
StreamSource src = new StreamSource(new StringReader(str));
ByteArrayOutputStream baos = new ByteArrayOutputStream();
Result res = new StreamResult(baos);
transformer.transform(src, res);
