Thanx in advance.You can get the information from the XML file using one of the parsers available, such as Xerces http://xml.apache.org, and JDOM as an API.
Using this you have the option of having a SAXParser or a DOMParser.
SAX (Simple API for XML) is an event based parser, so if you know the XML structure, and need to find a certain element, you can just look for the element name,and retrieve the value of the element, it's attributes and its children.
DOM(Document Object Model)represents the XML as a tree, but uses more resources as it stores the entire tree in memory. But it is good in that you can traverse the whole tree.
JDOM would be a good idea too. If you download this, you can use it's API, which is very good, that will use the parser on your system (Xerces). I would definately recommend JDOM.

How do I generate XML File Using JDeveloper 9.0.3

Hi All
I want to generate a XML file against the data in one of my Oracle table,,,, This is the first time I am doing this Task, so please let me know whether I am going through the correct path, or if not appreciate if you could put me to the correct system of doing this please��..
OK , Well I am working to a publishing company in Australia and we have Oracle 8i (Release 3 ) database and I have Oracle JDeveloper (9.0.3 -Preview ) version in my personal computer.
I have a Table(ONIXT4) with three Columns( ISBN,Author,Price) in Oracle as follows:
ISBN     Author     Price
2512456321     Peter     14.50
7445854127     Ray      21.75
What I want to generate a XML File using JDeveloper as below with respect to data in above Table.
<ISBN>2512456321</ISBN>
<ProductInfor>
<Author>Peter</Author>
<Price>14.50</Price>
</ProductInfor>
<ISBN>7445854127</ISBN>
<ProductInfor>
<Author> Ray </Author>
<Price>21.75</Price>
</ProductInfor>
I created the database connection within JDeveloper to Oracle those working fine,, my major problem is,, the Tag <ProductInfor>, since this is not a Column Name of the Table I don't know how should I incorporate this with the file.
What I did so far with the JDeveloper:
1.Create the Workspace and the Project
2.File -- New -- XML -- XSQL
3.Then I Selected Query from the Component Palette,, Property Values were NOT changed, and gave 'Select * from ONIXT4'
Whole Untitled3.xsql file look likes below
<?xml version = '1.0' encoding = 'windows-1252'?>

<page xmlns:xsql="urn:oracle-xsql" connection="Connection1">
<xsql:query max-rows="-1" null-indicator="no" tag-case="lower">
Select * From OnixT4
</xsql:query>
</page>
Then the Result comes as:
<?xml version="1.0" encoding="windows-1252" ?>
- 
- <page>
- <rowset>
- <row num="1">
<isbn>2512456321</isbn>
<author>Peter</author>
<price>14.5</price>
</row>
- <row num="2">
<isbn>7445854127</isbn>
<author>Ray</author>
<price>21.75</price>
</row>
</rowset>
</page>
How do I format the outcome to obtain the my requirement??
Welcome all comments of donig this ....

To format your XML to the requiered output you'll use a stylesheet and XSLT
As it says in your output:

A nice tutorial on XSLT is available on the XML technology center in OTN:

SAX: How to create new XML file using SAX parser

Hi,
Please anybody help me to create a XML file using the Packages in the 5.0 pack of java. I have successfully created it reading the tag names and values from database using DOM but can i do this using SAX.
I am successful to read XML using SAX, now i want to create new XML file for some tags and its values using SAX.
How can i do this ?
Sachin Kulkarni

SAX is a parser, not a generator.Well,
you can use it to create an XML file too. And it will take care of proper encoding, thus being much superior to a normal textwriter:
See the following code snippet (out is a OutputStream):
PrintWriter pw = new PrintWriter(out);
      StreamResult streamResult = new StreamResult(pw);
      SAXTransformerFactory tf = (SAXTransformerFactory) TransformerFactory.newInstance();
      //      SAX2.0 ContentHandler.
      TransformerHandler hd = tf.newTransformerHandler();
      Transformer serializer = hd.getTransformer();
      serializer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");//
      serializer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"pdfBookmarks.xsd");
      serializer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"http://schema.inplus.de/pdf/1.0");
      serializer.setOutputProperty(OutputKeys.METHOD,"xml");
      serializer.setOutputProperty(OutputKeys.INDENT, "yes");
      hd.setResult(streamResult);
      hd.startDocument();
      //Get a processing instruction
      hd.processingInstruction("xml-stylesheet","type=\"text/xsl\" href=\"mystyle.xsl\"");
      AttributesImpl atts = new AttributesImpl();
      atts.addAttribute("", "", "someattribute", "CDATA", "test");
      atts.addAttribute("", "", "moreattributes", "CDATA", "test2");
       hd.startElement("", "", "MyTag", atts);
String curTitle = "Something inside a tag";
          hd.characters(curTitle.toCharArray(), 0, curTitle.length());
    hd.endElement("", "", "MyTag");
      hd.endDocument();
You are responsible for proper nesting. SAX takes care of encoding.

How to write as XML file using java 1.5

hi all,
i am trying to create an XML file using java 1.5. I took a XML creating java file which was working with java 1.4 and ported same file into java 1.5 with changes according to the SAX and DOM implmentation in java 1.5 and tried to compile.

outf.flush();

Hi,
when I look in the JDK1.4.2 specification I don't see any write method in the Document interface.
However, your solution is the Transformer class. There you transform your DOM tree into any output you need. Your code sould look something like this:     TransformerFactory tf = TransformerFactory.newInstance();
     // set all necessary features for your transformer -> see OutputKeys
     Transformer t = tf.newTransformer();
     t.transform(new DOMSource(xmlDoc), new StreamResult(file));Then you have your XML file stored in the file system.
Hope it helps.

How to Save a XML file using Document Object

Hai all,
I am new to XML and i created a application to insert a node in the XML file using org.w3c.dom.Document object. And want to know which method has to be used to store the Document object into a XML fille.

The standard way would be to use a transformer with no transformation where the destination is a StreamResult.
something like:
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer();
transformer.transform(new DOMSource(doc), new StreamResult("output.xml"));

How to put data into textbox using JSP

How can I put data into a textbox using JSP?
This code prints to a html page but I want it inside an text area:
// Print out the type and file name of each row.
        while(ftplrs.next())
            int type = ftplrs.getType();
            if(type == FtpListResult.DIRECTORY)
                out.print("DIR\t");
            else if(type == FtpListResult.FILE)
                out.print("FILE\t");
            else if(type == FtpListResult.LINK)

You should update your DOM document to represent the changes that you want made.
Then, using the Transformation API you simply transform your document onto a stream representing your file. Something like this:
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
// TODO - set indentation amount!
Source source = new DOMSource(dom);
Result result = new StreamResult(file);
transformer.transform(source, result);Hope this helps.

Hi,
im trying to upload an html page using JSP and jdbc. but of no success.
my aim is to keep some important html pages in the database.the file size can vary.the file has to be selected from a local machine (through the browser) and uploaded to a remote machine(where the databse resides).
any help/sample code or pointer to any helpful link is appreciated.
thanks in advance

When uploading a file, I use a byte array as a temporary buffer..
So, you should then be able to store the byte array in the
database as binary data.
example>
//Temporary Buffer To Store File
byte[] tmpbuffer = new byte[860];
//Some Code To Upload File...
//File Should Now Be In Byte Array
//Get DB Connection and execute Prepared Statement
Connection con=//GET DB CONNECTION;
String sql=insert into TABLE(page) values(?);
PreparedStatement ps=con.prepareStatement(sql);
ps.setBytes(1,tempbuffer);
ps.executeUpdate();
//Close PS and Free DB Connection
..... and this method looks like you dont even have
to store the file in a byte array, you can just give
it the input stream.
ps.setBinaryStream(int, inputStream, int);
You may have to make several attempts at this. I have
uploaded a file and temporarily stored it in a byte array,
but have never from there stored it in the DB as binary
data.. but this looks like it'll work.
Good Luck!
