Converting XML and XSL into HTML

Hello!
I'm designing a servlet class that merges an xml file and xsl file into html that will be sent to the client. But I don't understand how the (sparsely documented) javax.xml.transform.dom package works. An exception is generated for a missing "version" tag, when I've included one that has worked on client-side xml/xsl pages before. If it matters, I'm using Apache Tomcat/JDK 1.4.
Here's the code:package mypackage.servlet.xml;
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.parsers.*;
import org.w3c.dom.*;
import org.xml.sax.*;
public class XML2HTMLServlet extends HttpServlet {
     public void doGet(HttpServletRequest request, HttpServletResponse response)
      throws IOException, ServletException {
          response.setContentType("text/html");
          PrintWriter writer = response.getWriter();
          try {
               openFile("D:/Webdev/xml2html/data.xml", "D:/Webdev/xml2html/style.xsl", writer);
          } catch (Exception e) {
               e.printStackTrace(writer);
     private void openFile(String xmlPath, String xslPath, PrintWriter writer)
      throws IOException, ParserConfigurationException, SAXException,
      TransformerConfigurationException, TransformerException {
          File xmlFile = new File(xmlPath);
          File xslFile = new File(xslPath);
          TransformerFactory tFact = TransformerFactory.newInstance();
          DocumentBuilderFactory dbFact = DocumentBuilderFactory.newInstance();
          DocumentBuilder builder = dbFact.newDocumentBuilder();
          Document xmlDoc = builder.parse(xmlFile);
          Document xslDoc = builder.parse(xslFile);
          Node xmlDocNode = (Node)xmlDoc;
          Node xslDocNode = (Node)xslDoc;
          DOMSource xmlSrc = new DOMSource(xmlDocNode);
          DOMSource xslSrc = new DOMSource(xslDocNode);
          DOMResult htmlResult = new DOMResult();
          Transformer transformer = tFact.newTransformer(xslSrc); // the exception occurs here!
When it runs, it complains:
javax.xml.transform.TransformerConfigurationException:
javax.xml.transform.TransformerConfigurationException:

</xsl:template>
</xsl:stylesheet>I'm not sure the method calls above are what I want, so here's the client-side equivalent in Internet Explorer 5.0:
function createStyledXMLDocument(xmlUrl, xslUrl) {
     var xmlDocument = new ActiveXObject("Microsoft.XMLDOM");
     xmlDocument.load(xmlUrl);
     var xslDocument = new ActiveXObject("Microsoft.XMLDOM");
     xslDocument.load(xslUrl);
     return xmlDocument.transformNode(xslDocument);
}Any help would be greatly appreciated.

Hi!
I found the immediate answer with
dbFact.setNamespaceAware(true);As for parser, I'm just using the default JDK install. But I'd like to hear more on Xalan. Is it independent open source? How does Xalan compare to whatever is default in JDK?
Thanks

There is never any guarantee that automatically generated html will look right on every browser, especially Explorer. For max compatibility with MS stuff it's best to use Office to start with instead of iWorks.
I don't know whether you could manually edit the Keynote html to make it work better with Explorer. It would be interesting to know whether it looks right in Windows Safari, Chrome, or FireFox so you could know whether only IE does it wrong.

Cannot view PDF created by passing xml and XSL-FO using UTL_HTTP

Hi,
Using UTL_HTTP Iam trying to contact a servlet which uses the input XML and XSL/FO to produce a PDF.However, when I run the procedure , I get the following error 'File does not begin with -%PDF' ? I checked the output on the console and the blob values does not start with %PDF . Below is the sample from my code , please let me know if Iam commiting a mistake somewhere. I confirmed that the servlet itself is working fine by confirming with test webpage that takes xml and stylesheet input and generates a PDF when 'submitted' to servlet on the click of a button.
INSERT INTO TESTPDF ( PDF_REPORT ) VALUES ( Empty_Blob() ) RETURNING PDF_REPORT INTO vBlobRef;
vReportURL :='/rufop/fop?xml='||xmldoc||'&xsltRPath=../../test/PAXSL.xsl';

resp := utl_http.get_response(req);
loop
begin
Utl_Http.read_raw(resp, vData);
Dbms_Lob.writeAppend ( lob_loc => vBlobRef , amount => Utl_Raw.length(vData) , buffer => vData );
exception
when utl_http.end_of_body then

end;
end loop;

Hello guys! I have been assigned the same task,i.e to generate pdf through xml using xsl stylesheet.
I have a procedure which is creating the xml and the stylesheet. But I have no idea how to write the procedure which passes this xml to fo engine. I am very new to this. Can anyone please share your thoughts with me so as how to accomplish this? By reading blogs on internet I figured I would have to use UTIL_HTTP but don't know how.

JSF, tiles, xml and xsl

Good days people, I am employed at an app that wants to integrate JSF, tiles, xml and xsl.
Basically the app receives information of the user's interfaz, builds an url with the above mentioned information and invokes to a service web that a xml returns with the information. The idea is to generate the exit in format html or wml with an insole(staff) xsl and to send the result in this format to every jsp that is going to form a part of the page that it will generate tiles. at first I understand that it is feasible, i�d like to know if someone already has done it and since it has done it.
Just now what I have is a managed bean that receives the parameters of the altar frontal and invokes a method of a service, like this:
public String encuentra(){
//deja los atributos privados rellenos.
String mensaje ;
crearYRellenarBusquedaVO();
try {
setResultado(this.getServicio().obtenerResultadosWML(this.getBusquedaVO()));
mensaje="succesNoJS";
}catch(java.lang.IllegalArgumentException e){
mensaje="error";
}catch(es.yell.frontlite.exceptions.SrvBusquedaNoxtrumServiceException e1){
mensaje="error";
}catch(Exception e2){
mensaje="error";
return mensaje;
public String obtenerResultadosWML(es.yell.frontlite.service.impl.BusquedaVO busquedaVO){
if (busquedaVO == null){
throw new IllegalArgumentException(
"obtenerResultadosJSdesactivado(es.yell.frontlite.service.impl.BusquedaVO busquedaVO) - 'busquedaVO' no puede ser nulo.");
try{
return this.manejarObtenerResultadosWML(busquedaVO);
}catch(es.yell.frontlite.exceptions.SrvBusquedaNoxtrumServiceException e1){
throw new es.yell.frontlite.exceptions.SrvBusquedaNoxtrumServiceException(
"Error ejecutando el servicio String obtenerResultadosJSdesactivado(es.yell.frontlite.service.impl.BusquedaVO busquedaVO). " + e1.getCause(),e1);
}catch(Exception e){
throw new es.yell.frontlite.exceptions.SrvBusquedaNoxtrumServiceException(
"Error ejecutando el servicio String obtenerResultadosJSdesactivado(es.yell.frontlite.service.impl.BusquedaVO busquedaVO). " + e.getCause(),e);
//it returns html code!
protected String manejarObtenerResultadosWML(es.yell.frontlite.service.impl.BusquedaVO busquedaVO)
throws java.lang.Exception{
try{
// xmlOrigen has full xml response from server
String xmlOrigen = manejarObtenerResultadosJSActivado(busquedaVO);
Source xmlSource = new StreamSource(new StringBufferInputStream(xmlOrigen));
Source xsltSource = new StreamSource(SrvBusquedaNoxtrumServiceImpl.class.getResourceAsStream(Constantes.XSL_FILE));
StringWriter cadenaSalida = new StringWriter();
Result bufferResultado = new StreamResult(cadenaSalida);
TransformerFactory factoriaTrans = TransformerFactory.newInstance();
Transformer transformador = factoriaTrans.newTransformer(xsltSource);
transformador.transform(xmlSource, bufferResultado);
System.out.println(cadenaSalida.toString());
return cadenaSalida.toString();
}catch(Exception e2){
throw new es.yell.frontlite.exceptions.SrvBusquedaNoxtrumServiceException (e2.getMessage());

Generating PDF with XML and XSL

Hi, quick basic question...
I'm trying to generate pdf doc from xml with xsl.
I'm using following sample code from xml.apache.org
response.setContentType("application/pdf");
Driver driver =new Driver();
driver.setOutputStream(response.getOutputStream());
driver.setRenderer(Driver.RENDER_PDF);
Transformer transformer=TransformerFactory.newInstance()
.newTransformer(new StreamSource("foo.xsl"));
transformer.transform(xmlsource, new SAXResult(driver.getContentHandler()));
xmlSource is my regular xml that wants to be pdf.
is foo.xsl any regular xsl that I use to coonvert xml into html?
or is it some special xsl that is tailored for pdf.
Is this what is called xsl-fo?
Thanks
IL

Hi IL,
XSLT can translate XML to something else. It is most suited to transforming to another tree-like format (XML, HTML, etc.) but can be 'asked' to produce other kinds of output, flat text for example.
It is driven by an XSL file which is a series of patterns to match and output to produce.
This XSL file can be used to generate another XML document in which the nodes come from the Formatting Object namespace. These describe, in generic terms the format of an output document based upon the contents of the original XML.
The formatting object XML document can then be used as input to a formatting object XML processor which can generate PDF output from it.
You may want to check out:
www.w3c.org
for all the stuff on XML, XSL, XSLT, Formatting Objects, etc., and:
xml.apache.org
for imformation on Xalan, which is an XSL processor and FOP, which is a formatting object processor.
Hope that helps,
Peter.

Convert all-Flash site into html?

to Dreamweaver 8 and Flash 8.

Sorry... unless you've separated the content out already,

easy way if

What I need for this?
Do I need the XSLT-File too?
I am waiting for your answers, when possible with examples please.

HELP!
Thanks, --bill

I am talking about the location TO which you are saving when it comes to space available and permissions. You should be able to see where it is when chosing save or export, And free harddiskspace on the main disk you are working from. Is the destination on a server?

Is there a tool to convert XML data model into berkeleydb automatically?
