Creating an xml file from java.

I trying to create an xml file using a java program. I just wondering what is the best way to go about it and what should i use jdom ,xerces sax etc.

Use JAXP+SAX.
Here an example:import java.io.*;
// SAX classes.
import org.xml.sax.*;
import org.xml.sax.helpers.*;
//JAXP 1.1
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.xml.transform.sax.*;
// PrintWriter from a Servlet
PrintWriter out = response.getWriter();
StreamResult streamResult = new StreamResult(out);
SAXTransformerFactory tf = (SAXTransformerFactory) SAXTransformerFactory.newInstance();
// SAX2.0 ContentHandler.
TransformerHandler hd = tf.newTransformerHandler();
Transformer serializer = hd.getTransformer();
serializer.setOutputProperty(OutputKeys.ENCODING,"ISO-8859-1");
serializer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"users.dtd");
serializer.setOutputProperty(OutputKeys.INDENT,"yes");
hd.setResult(streamResult);
hd.startDocument();
AttributesImpl atts = new AttributesImpl();
// USERS tag.
hd.startElement("","","USERS",atts);
// USER tags.
String[] id = {"PWD122","MX787","A4Q45"};
String[] type = {"customer","manager","employee"};
String[] desc = {"Tim@Home","Jack&Moud","John D'o�"};
for (int i=0;i<id.length;i++)
atts.clear();
atts.addAttribute("","","ID","CDATA",id);
atts.addAttribute("","","TYPE","CDATA",type[i]);
hd.startElement("","","USER",atts);
hd.characters(desc[i].toCharArray(),0,desc[i].length());
hd.endElement("","","USER");
hd.endElement("","","USERS");
hd.endDocument();
[i]This xml generation program might be the best solution because it uses JAXP 1.1 so it will work under JDK 1.4 or JDK 1.2/1.3 with XALAN2 library (or any XML library JAXP 1.1 compliant). It's also memory-friendly because it doesn't need DOM.
See http://www.javazoom.net/services/newsletter/xmlgeneration.html
Hope That Helps

How I can create a XML file from java Aplication

How I can create a XML file from java Aplication
whith have a the following structure
<users>
<user>
<login>anyName</login>
<password>xxxx</password>
</user>
</users>
the password label must be encripted
accept any suggestion

Let us assume you have all the data from the jsp form in an java bean object..
Now you want a xml file. This can be acheived in 2 ways
1. Write it into a file using java.io classes. Say you have a class with name
write("<name>"+obj.getName+</name>);
bingo you have a flat file with the xml
2. Use data binding to do the trick
will recommend JiBx and Castor for the 2nd option

Create an XML file from Java

I'm a new user of XML. I've a very important question:
Is it possible create an XML file using some java package? If yes what package i must use? JDOM is the right product?
Thanks

Yes, JDOM is the right choice for 99% of your work.
DOM is too difficult to use.
That is the reason why JDOM has been developped.

Create dynamically xml file from java.

Hi all,
I got class information in java program. I have to put method name and return type into xml. The xml file is like this and i have created this file.
<method>
<name></name>
<returnType></returnType>
</method>
Now when I get method information I want to put it in xml, not by writing each method name explicitly in file, mean i have to load this xml into memory for that what should i do?
Please help me I am new in XML.
Thanks in advance.
-regards
bunty

If you save your XML file as "methodinfo.xml", you can use the following code:import java.io.File;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Node;
try {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder parser = factory.newDocumentBuilder();
Document doc = parser.parse(new File("methodinfo.xml"));
Node nameNode = doc.getElementsByTagName("name").item(0);
Node returnTypeNode = doc.getElementsByTagName("returnType").item(0);
nameNode.setTextContent("the name of the method");
returnTypeNode.setTextContent("the return type of the method");
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(System.out);
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
System.out.println("This is the content of the XML document:\n");
transformer.transform(source, result);
catch (Exception e){
...The content of the XML document will be displayed as follows:<?xml version="1.0" encoding="UTF-8" ?>
<method>
<name>the name of the method</name>
<returnType>the return type of the method</returnType>
</method>

Creating XML file from Java Bean

Create XML file from java

Hi all i am working to create a XML file using java can any one show me some sample code how to do so

All I suggested was to insert a single line ("X.serialize(root);") into your code. Anyway, here's a ready-to-compile source code based on yours. This code utilizes the Xerces-J class library.import java.io.File;
import java.io.FileWriter;
import org.apache.xerces.dom.DocumentImpl;
import org.apache.xml.serialize.OutputFormat;
import org.apache.xml.serialize.XMLSerializer;
import org.w3c.dom.Element;
public class Test {
public static void main(String[] arguments) {
    FileWriter out;
    DocumentImpl d;
    Element root;
    XMLSerializer X;
    try {
      System.out.println(" creatin ");
      File fos = new File("xsr.xml");
      out = new FileWriter("xsr.xml");
      System.out.println("created File .." + fos.getName());
      out.flush();
      d = new DocumentImpl();
      System.out.println("create root");
      root = d.createElement("abc");
      System.out.println("creating element");
      d.insertBefore(root, null);
      //out.write(d.createAttribute(""));
      OutputFormat o = new OutputFormat(d);
      System.out.println("Output format...");
      o.setIndent(5);
      o.setIndenting(true);
      o.setDoctype("lab1.dtd", "lab1.dtd");
      o.setDoctype("name of dtd file", "name of dtd file");
      X = new XMLSerializer(o);
      X.setOutputCharStream(out);
      X.serialize(root);
      out.flush();
      out.close();
    catch (Exception e1){
      e1.printStackTrace();

How to modify an existing xml file from java code.

Hi
I have worked on creating a new xml file from java code using xmlbeans.But if i try to modify an already existing file using java code I am unable to get errorfree xmlfile.
For example if xml file(studlist.xml) is as below:
<?xml version="1.0" encoding="UTF-8"?>
<StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
     <Student>
          <Name>ram</Name>
          <Age>27</Age>
     </Student>
<Student>
          <Name>sham</Name>
          <Age>26</Age>
     </Student>
</StudentList>
Now suppose i have set name to victor using student.setName,
and set age to 20 using setAge from javacode,
the new xml file is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
     <Student>
          <Name>ram</Name>
          <Age>27</Age>
     </Student>
<Student>
          <Name>sham</Name>
          <Age>26</Age>
     </Student>
</StudentList>
<Student>
          <Name>victor</Name>
          <Age>20</Age>
     </Student>
As observed this is not a valid xml file.But how can i modify without any errors?

I know it's an old post, but I found this while doing a google search for something else, and don't like to leave it un-aswered
Just in case anyone has a similar problem... In this case the new elements have been appended outside of the root element
What you need to do is first get the root element and then append the new children to that, there are several ways of getting the root element, which depend on what you want to do with the elements you get back here's a simple (incomplete) way.
// gets the root element of the specified file (code not shown)
Element rootElement= new SAXReader().read(file).getRootElement();Then just append the new elements as below (this is non-generic code and would need to be modified for your situation)
// write a new student element
Element student = document.createElement("Student"); // creates the new student
rootElement.appendChild(student); // ***appends it to the root element***
Element name = document.createElement("Name"); // creates the name element
name.appendChild(document.createTextNode("Fred")); // adds the name text to the name element
student.appendChild(name); // appends the name to the student
Element age= document.createElement("Age"); // creates the age element
age.appendChild(document.createTextNode("26")); // adds the age text to the age element
student.appendChild(age); // appends the name to the studentThen flush ya buffers or whatever and write the file

Creating an xml file from recordset

Hi...
XML newbie here - so.
Is it possible to create and xml file from a recordset?
I need to create a datafeed of our e-commerce products.
Also, some of the db data contains HTML Code (product
description field),
how will this effect the xml file?
Another problem is that my xml file needs to contain url's
for the products
and product images. My ASP pages contain these URL in hard
code and then
pull the actual file names from the db
Hope that makes some sense
Thanks for any help
Andy

Hi David
Thanks for your help.
I think it will have to be option 1 as i am using Access DB.
I don't know how to go about it but will serach good old
Google.
Here is my recordset below, that pulls the required data from
Access.
The product and product image URL's need to be in the xml
file but only the
product image name and product id are in the database, e.g
image name
(imagename.jpg) productid (21)
The actual URL's are hardcoded in my ASP pages, e.g <img
src="products/medium/<%=(RSDetails.Fields.Item("Image").Value)%>"
Not sure if this makes things any clearer :-|
Thanks Again
Andy

Creating an xml file from a playlist - message for iTunes staff

When I created an xml file from a playlist I noticed that in the xml file the track name was merged with the artist name in this manner "I want you - Bob Dylan".
That was hardly a problem as I could easily correct this in the FileMaker Pro environment.
But subsequently I found out, that within iTunes the track name was similarly changed to the same format. Apparently this happened when iTunes created the xml file and inadvertently also changed the track name within iTunes.
It can easily be corrected by entering File/Info, but I had over 10.000 songs in that list and it will take a lot of time. I have to do this, as I created earlier for each song a file path in FileMaker Pro, which are unrecognizable now.
Could you please correct the xml file creating procedure?

I must confess that I can't reproduce this result myself anymore.
I created the xml file in iTunes via File/Library/Export Playlist/xml structure (I translate the Dutch terms loosely) and subsequently I imported the xml file into a Filemaker Pro via File/Import/xml.
The xsl style sheet looks ok.
It looks like a freak of nature.
Still I have the evidence in my iTunes playlist, where I have another 9000 clicks to go to repair the damage.
Let's forget about it, until it happens again.
Thanks for your time.

Is there anyway to create a xml file from a list so that xml file is available like an RSS.xml

Hello
My objective is to have a xml file created from a list for anonymous access. The SharePoint RSS feed is a .aspx file not xml, as shown below:
_layouts/listfeed.aspx?List=21c2cdaa%2D52f3%2D4057%2Db674%2D45e63ba77e31&View=535eb328%2Db5fb%2D45c5%2D8fe8%2Da130e92afc41
Also, is there a way to do this so that the xml content has current data like the list.
Thank you for any insight and direction.

Hi,
According to your post, my understanding is that you wanted to create a xml file from a SharePoint list.
To generate a XML file, we can use the SharePoint Object Model or PowerShell to achieve it.
