How to Read and Generate XML file from java code.

hi guys,
how to read the xml file (Condition :we know only DTD or Shema only).
How to Generate the new xml file ?(using Shema )
And one more how directly Generate the xml from DB?
Pleas with code or any URL

Using XMLbeans you can generate Java objects from an XSD schema (perhaps DTDs aswell)
Then you can create an instance of the Document object and ask it to write itself.
This will create an XML document complient to the schema.
XMLBeans generates a "type" safe DOM where you can only ever have a structure compilent to you schema.

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

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>

<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

Thanks for your answer. I downloaded the JDBC AddressBook application and I found it very usefull. I was able to populate a datalist from a datasource and show it in my application. My problem still remains in the sense that I am unable to show the KPI data in a "custom node" meaning I woul like not only to extract directly the database record to a datalist object but also put the information of a single record in a textbok and a gauge and keep control of paging. I think this is done with the parser in the other examples but I can not figure out how to do it with MySQL and the new Desktop screen designer. Should I use a clip object? or is that managed already by the desktop screen designer? or where can I find an example with the functionality I need?.

How to generate XML file from SQL file !

I am new to XML publisher. I known one way to generate XML file is register one report file in concurrent manager.
But I want to generate XML file from sql file.
Could someone show me how to code in sql file, how to register is in concurrent manager.
Thanks !

Hi
Phew ... not sure we have the space here. So I can point you in the right direction:
1. XML data generation - there are two packages in the db you can use with a plsql procedure, XMLGEN and SQL XML. You can also use java APIs too. Try checking the db documentation and search for the above methods.
2. Registering the report - the system administrators guide will provide this info. Hooking the program up with XMLP is covered here - http://www.oracle.com/technology/products/applications/publishing/resource/CM%20Whitepaper5.0.pdf

Generate XML File from table

How to generate XML file from a table without using UTL_FILE that too in local machine...

You downloaded the wrong XML Parser!
XSQL requires Java Parser. Well, there's a copy included with the XSQL package so you actually don't need to do another download.
You really don't need XSQL if you just want a XML file from DB, you just needed a XML SQL Utility. Download that and run the samples.
