    doc.appendChild(root);
    // append a data
    Element body = doc.createElement("body");
    root.appendChild(body);
    body.appendChild(doc.createTextNode("Hello"));
    // convert DOM to XML Document
}----- expected result ----------
<html>

Can't get the DOM to output XML document tags in correct order.

I'm trying to output an XML document from the DOM using the DOMWriter class: new DOMWriter(document, filename, outputEncoding, encodingTag, getDocTypeString());
It refuses to output the tags in the correct order so my document always fails validation when it is read back in. I've tried explicitly placing the elements in the correct order into the DOM and it still outputs them the way it wants to. Is there some method I'm missing to set the xsd or dtd to validate the output on. It actually appears as though it has a definite idea as to what order the tags should be output, because no matter what order I append the nodes into the document, it always outputs them in the same incorrect order. I've got the validation working when it reads the document in. Does anyone know what I have to do to get it to output the tags in the correct order?

Does anyone know what I
have to do to get it to output the tags in the correct
order?You have to build the DOM in the correct way. Based on the code you posted it's impossible to tell what you are doing wrong. How about posting some code?

Fm 12 - How can I include a graphic in an XML document that will be zoomable when converted to HTML5?

I'd like to inc;lude grahics in my help files when authoring them in xml and converting them to Responsive HTML5 web documents. I'm not sure of the proper way to inc;lude javascript scripts into the XML documents that could be used to make the images zoomable and panable. Codeblock elements don't seem to work - all that happens is the text of the script is displayed in a font different from the font I'm using for the Help text. Maybe I'm using the wrong elements? I'm using Framemaker 12. Any ideas here would be greatly appreciated.

Anyone? Im also frustrated about this

Inserting XML document into XDB fails with can't convert to OPAQUE

Hi,
When I try to insert a document using oracle 9.2.0.5 client software into a 9.2.0.5 database, with the following code:
void insertDocument(String document) {
XMLType xt = XMLType.createXML(connection, document);
PreparedStatement ps = connection.prepareStatement("insert into xmldocuments values(?)");
ps.setObject(1, xt);
ps.executeUpdate();
The setObject function always throws an exception (after a very long time) with:
java.sql.SQLException: Fail to convert to internal representation: OPAQUE()
This also fails when we use the InputStream and org.w3c.xml.Document variants.
We use the OCI driver, otherwise we get errors retrieving the documents from XMLDB.
What is going wrong here?

David,
If you search through the historical data in this list there are previous post regarding opaque.
These may be useful. Possibly your reaching the size limit.

Converting XML document to HTMl using xsl

Converting XML Document to String

Dear All,
I am quite new to Java Web Services. I have made a Java Class which calls all the web services . I am displaying the results on a Command prompt. Below is my sample code:
import javax.xml.rpc.Service;
import javax.xml.rpc.Stub;
import horusWS.Horus_x0020_Web_x0020_Services_Impl;
import horusWS.Horus_x0020_Web_x0020_ServicesSoap;
public class JavaClient {
public static void main(String[] args)
Horus_x0020_Web_x0020_Services_Impl service = new Horus_x0020_Web_x0020_Services_Impl();
Horus_x0020_Web_x0020_ServicesSoap port = service.getHorus_x0020_Web_x0020_ServicesSoap();
String str;
str = port.getTextFeedbackLearner(1,"P001",1);
//where getTextFeedbackLearner is the my Web Service.
System.out.println(str);
System.out.println returns the web service in string format. Now I want to compare this string to my actual getTextFeedbackLearner.xml file. But I think I need to convert getTextFeedbackLearner.xml to string first. Please let me know
how can I convert an XML Document to String.
Thanking you in Anticipation.
cheers,
Sunil Sabir

You can read the XML document as you read any other file.
Read it into a String variable.
Check java.io.FileReader, java.io.BufferReader, etc.

Xml document converting to pdf

Hi,
I have a question regarding the convertion of xml document to pdf document.
Below is the scenario.
I have an xml document stored in the table in a CLOB format. I would like to convert the xml document stored in a table to pdf document and display in a Web browser.
I have written the stylesheet to convert the xml document to the xsl fo(XSL Formatting object xml) type document. I need to apply FOP Processor to convert into pdf document.
How do i do that in PL/ SQL ?
Any thoughts ??

1. Generate a XSL-FO document by applying an XSLT to the XML document in the database.
2. Convert the XSL-FO document to a PDF document.

Filling tab of an XML document created by DOM

have a problem with filling tab of an XML file created by DOM
I used this code to create the document:
public class DOMCreation {
public void createDOM( String a, String b ) {
          Document doc = new DocumentImpl( null );
          // Il codice che segue � indipendente dal particolare parser utilizzato
          // Creazione dell'elemento root del documento, identificato dal tag <DOCUMENT>
          Element root = doc.createElement("DOCUMENT");
          doc.appendChild(root);
          // Creazione ed inserimento di un nodo
          Element element1 = doc.createElement("USERNAME");
          root.appendChild( element1 );
          // Creazione ed inserimento di un secondo nodo discendente di <DOCUMENT>
          root.appendChild( doc.createElement("PIN") );
System.out.println( a );
System.out.println( b );
          try {
               serializeDocument( doc, new FileOutputStream("d:/doc.xml"));
          } catch (FileNotFoundException e) {}
private static void serializeDocument(Document doc, OutputStream output) {
          try {
               DOMSerializer ser = new XMLSerializer( output, null);
               ser.serialize(doc);
          } catch (IOException e) {
               System.err.println("I/O exception while serializing document: " + e.getMessage());
}

The code lines:
System.out.println( a );
System.out.println( b );
had the purpose to check if these two parameters were passed by another procedure. These two parameters, however, represent the content to be filled in the tag of XML document created by DOM.
About the other question on "what parser do you use", I'm using Apache's Xerces. However that's the "import" that I include in this procedure:
import org.apache.xerces.dom.DocumentImpl;
import org.apache.xerces.dom.NodeIteratorImpl;
import org.apache.xml.serialize.*;
import org.w3c.dom.*;
import org.w3c.dom.traversal.*;
import java.io.*;

How can I use DOM to copy Nodes between different XML Document ?

Can I copy one Node or Element from one XML Document to another Document by DOM ?
Because I use the Xerces , but it is not work if I want to copy Node between different Document, or I am doing something wrong. Anyone can help me , I will deeply appreciated !!

check out the importNode() method of Document.
