XML to XSL Performance

Hello All,
I've been involved with many web-apps that produce XML and then use XSL to provide the look and feel. My question is whether you have found that XSLT causes a bottle neck on CPU time when the server is busy. Is there a way round this? Sometimes time spent in XSL can be upto 0.8 to 1 second as the server becomes busier!
Thanks
Mike

I haven't tried caching the XSL templates... is this likely to speed up processing by much?
The reason I called this a bottleneck was because I loaded the server with a lot of requests ( around 50 clients ) constantly hitting the server as soon as a reply was received, and the server ground to a halt and began to take a long time to process XSL due to CPU at 100% utilisation.
Thanks
Mike

How can I use JavaScript extention functions with Xalan for transforming XML with XSL

While transforming standart XML and XSL files to HTML with this servlet:
package mypackage1;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import java.net.URL;
import javax.xml.transform.*;
import javax.xml.transform.stream.StreamSource;
import javax.xml.transform.stream.StreamResult;
import org.mozilla.javascript;
public class Servlet2 extends HttpServlet
private static final String CONTENT_TYPE = "text/html; charset=windows-1252";
public void init(ServletConfig config) throws ServletException
super.init(config);
public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException
try
response.setContentType(CONTENT_TYPE);
PrintWriter out = response.getWriter();
TransformerFactory tFactory = TransformerFactory.newInstance();
Source xmlSource = new StreamSource(new FileReader("c:/aaa.xml"));
Source xslSource = new StreamSource(new FileReader("c:/bbb.xsl"));
Transformer transformer = tFactory.newTransformer(xslSource);
transformer.transform (xmlSource, new StreamResult(out));
catch (Exception e)
e.printStackTrace();
everything is going ok,
but when try to use javascript function in XSL file, for example like in this:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
xmlns:lxslt="http://xml.apache.org/xslt" xmlns:my-ext="ext1"

<lxslt:component prefix="my-ext"

<lxslt:script lang="javascript">
function getdate() {
var d = new Date();
return d.toUTCString();
</lxslt:script>
</lxslt:component>
<xsl:template match="/">
<p><xsl:copy-of select="my-ext:getdate()"/></p>
</xsl:template>
</xsl:stylesheet>
recieve error-message:
XSL-1000: (Fatal Error) Error while parsing XSL file (Extension function namespace should start with 'http://www.oracle.com/XSL/Transform/java/'.).
What kind of namespace I should specify?

Hello, Paul.
I'm sure you may not use JavaScript as a language for creating XSLT extention functions with Oracle XDK Parser. This is since parser might have JavaScript interpreter to work with JavaScript, but it has not.
If you need to build any XSLT extention functions you must build them as Java class' static methods.
After that, you define the usage of the class by mean of namespace declaration as:
xmlns:your-ns="http://www.oracle.com/XSL/Transform/java/yourpackage.Yourclass"
(Prefix "http://www.oracle.com/XSL/Transform/java/" may differs if you use non-Oracle XML parser)
and use class' static method in XSLT:
<xsl:value-of select="your-ns.staticMethodName(paramsIfAny)"/>
In your case you may wish to use standard Date class:
xmlns:date="http://www.oracle.com/XSL/Transform/java/java.util.Date"
<xsl:value-of select="date:toString(date:new)"/>

Unable to display a variable value in xml through xsl using coldfusion

Hi ColdFusion Heroes ,
Is their any one to help me in this issue . I am new to cold
fusion , XML and XSL .
Detail Explaination :
develoment_files.cfm is a .cfm page , which includes an xml
page .
development_files_dropdown.xsl is a xsl page .
develoment_files.cfm : Code is as follows .
<CFDIRECTORY ACTION="LIST" DIRECTORY="#somepath#"
NAME="DirContents" FILTER="p*">
<CFQUERY DBTYPE="query" NAME="Files">
SELECT *
FROM DirContents
WHERE Type = 'File'
</CFQUERY>
<CFOUTPUT><?xml version='1.0' encoding='UTF-8'?>
<?xml-stylesheet type="text/xsl"
href="../XSL/development_files_dropdown.xsl"?>
<Test xmlns:xsi='
http://www.w3.org/2001/XMLSchema-instance'>
<CFLOOP QUERY="Files">
<Directory>
<DisplayName>#Name#</DisplayName>
<FullPath>#Name#</FullPath>
</Directory>
</cfloop>
</Test></CFOUTPUT>
This file generates a query resulting files starting with p*
and then it should be a file and manipulates in xml.
development_files_dropdown.xsl pages is as follows.
<?xml version='1.0'?>
<xsl:stylesheet version="1.0" xmlns:xsl="
http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="yes"/>
<xsl:preserve-space elements="*"/>
<xsl:template match="/">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="Test">
<B>Script Name: </B>
<select name="T1_Dev_Script" CLASS="DevInput">
<xsl:for-each select="Directory">
<option>
<xsl:attribute name="value">
<xsl:value-of select="FullPath/text()"/>
</xsl:attribute>
<xsl:value-of select="DisplayName/text()"/>
</option>
</xsl:for-each>
</select>
</xsl:template>
</xsl:stylesheet>
This is only for the purpose of display .
Now i want to get one particular file named "pfile" { Code is
written in development_files.cfm page and kept it in a variable } I
want to display it in #Name# filed. how can i do that ? I am
getting XML Parsing error from javascript .
Could any one look into this .
Thanks & Regards,
Nataraj G

The first part is right -
1) drag a text element onto the page, at a location in which you want the variable value to be displayed
2) On the left hand bottom page - go to the web item properties for the text element
3) scroll down to the specific properties for the item - in that uncheck the first two check boxes - display general text elements & display static filter values
4) in the next item in the properties (List of text elements) click once on the box where List is written and then clcik on the small browse button that appears.
5) in the window that opens, in the element type field, select variable/variable value as key (as per your requirement) and then under the element ID field type in the technical name of your variable that you want to display.
click ok and save your template and try executing it.
See if this solves your problem.

Nikhil

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';
req := UTL_HTTP.BEGIN_REQUEST (url=>vReportURL, method=>'POST');
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
exit;
end;
end loop;
Utl_Http.end_response(resp);
owa_util.mime_header('application/pdf',false);
htp.p('Content-Disposition: inline; filename="test.pdf"');
htp.p('Content-Length: '|| dbms_lob.getlength(vBlobRef));
owa_util.http_header_close;
wpg_docload.download_file(vBlobRef);
Thanks in advance,
Jen

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.

I am using the same XSL file. My Java program use the same XSL file I used in the command line.
It is possible that my Java code is using a different parser, but I developed a seperate program to parse the XML using the same parser that my Java code is using. It output the result I expected. Here is the code for the program:
import java.io.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
public class Convertor {
public static void main(String[] args) throws Exception {
String xslDoc = "MARC21slim2MODS.xsl";
String xmlResult = "out.xml";
String xmlDoc = marc.xml";
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new StreamSource(xslDoc));
StreamSource xmlSource = new StreamSource(xmlDoc);
FileWriter fw = new FileWriter(new File(xmlResult));
StreamResult output = new StreamResult(fw);
transformer.transform(xmlSource, output);
}

XSL-1009 error in XML to XML using XSL

I'm using XSL to transform one XML format to another using and XSL transform file. I'm initiating this with ORAXSL in.xml transform.xsl out.xml. The XSL file has in it:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.oracle.com/XSL/Transform/Java" version="1.0">
<xsl:import href="../generic/parsePOHeader.xsl"/>
<xsl:import href="../generic/parsePOLine.xsl"/>
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
ORAXSL gives an error of XSL-1009: Attribute xsl:version not found in XSL:Stylesheet.
Putting an XSL: prefix on the version doesn't help. A search for help on this site had a solution for XSL that create HTML.
Has anyone else solved this problem?

Thanks everyone for th ereply. Yes, I tested the mapping in integration bulider and it works fine. Even the file conversion works fine intermittantly! Sometimes it converts successfully and wrties file to target location and sometimes I get this error. I checkd in sxi_cache and I see the mapping xsl files there. I jus had basis reboot PI server and run some cache commands but still same problem! Also, when I have to files in source directory sometimes it converts both, sometimes one and sometimes both fails! I haveno clue what els to try.
What are adapter nodes and wher can I check for that?
Thanks.

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());
With this exit in html, since(as,like) how could i forward it towards a jsp especially?

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.

How to convert to ' ' in xml using xsl.

Hi all,
I have a string downloaded which has the following string
String= text1 <I> text2 </I⁢
I have italics tag in my xml file. But my browser does not identifies italics. So i decided to comment out italics tag in my xml using xsl
So what i need is
String = text1 text2
basically to comment out italics tag alone.
How can i replace <I> to ?
Is there any way in xsl to do the above in a string?
or
Any other ways where i can just remove <I> in my out xml file using xsl?
Thanks in advance.
Menaga.

Hi,
The ultimate solution would be that you also install also a cocoon server (http://cocoon.apache.org/), but that might be overkill.
Have a look at /people/sap.user72/blog/2004/11/10/bsphowto-generate-pdf-output-from-a-bsp for detailed info on creating PDF from BSP.
If you want to use XSL(-FO), you might have a look at things like http://alt-soft.com/products_xml2pdf.jsp to be called as external command.

XML Parsing with XSL Performance lag

Hi there
I should qualify this post by saying I am fairly new to EJB's and have based the below on a Java Working with XML Tutorial I read.
I have an EJB which is being developed to parse XML documents with an XSL stylesheet and return HTML for display. The code is working fine however there is a fairly hefty performance lag when using the EJB to generate the HTML as opposed to the straight HTML. I am getting an average response time of 95000ms using the EJB as opposed to 45000ms when viewing the straight HTML. The code I am using to do the parsing is :
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(dataFile);
// Convert docs into StreamSource
StreamSource stylesource = new StreamSource(styleSheet);
StreamSource source = new StreamSource(dataFile);
StringWriter strWrite = new StringWriter();
StreamResult result = new StreamResult(strWrite);
// Use a Transformer for output
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(stylesource);
transformer.transform(source, result);
There is then some error handling and the strWrite object is placed into an array to be returned.
I am really looking to find out if the performance lag I am experiencing is normal or if there is anything I can do to improve the speed of the code.
All comments and help is most appreciated.
Cheers
Justin.

You should be able to increase performance by caching Templates objects in memory as a previous post suggested.
Here is some untested code:public final class TransformerCache
     private static Map cache = new Vector();
     private TransformerCache(){}
     public static Transformer getTransformer( String filename )
          if( ! cache.containsKey( filename ) )
               TransformerFactory tf = TransformerFactory.newInstance();
               Templates template = tf.newTemplates( new StreamSource( filename ) );
               cache.put( filename, template );
          return ( ( Templates ) cache.get( filename ) ).newTransformer();
}This aproach works in a clustered environment, just bear in ming that there will be an instance of the cache on each server instance (virtual machine).

Java.lang.OutOfMemory error when transforming xml using xsl with Weblogic 6.1 sp2

Hello,
I have an OutOfMemoryError when applying an xsl transformation to generate html
code in a web page. I'm running Weblogic 6.1 sp2
I think the problem comes from the objectin which th html is stored during the
transformation. The problem only occurs from a minimal xml size. I could fix
it by increasing JVM allocated size but I would like to find a more flexible solution.
If I know an other way to solve this problem, I really would appreciate !
Thanl you,
Laurent.

Hello,
You might try asking your question in the JSP newsgroup:
http://newsgroups.bea.com/cgi-bin/dnewsweb?cmd=xover&group=weblogic.developer.interest.jsp
There just may not be a more flexible solution :-)
This doc may be of some value, see chapter 2:

XSL Performance

Has anyone conducted a performance evaluation of the Oracle XSL
processor? I am currently using the LotusXSL processor and am
finding it VERY CPU intensive. It is prohibitively slow.
Does anyone have any comparisons?

Since this message exists and there are no responses in a month,
I'm guessing that this continues to be an unresolved problem?
I'm getting ready to bail on XSL because of the performance.
I'm seeking out a better performing XSL processor. Anyone know
of any?

XML data source - Performance problem

Environment - Crystal Reports 2008 , crjava-runtime_12.2.200 jar files, Java 1.5 and XML data source
We are generating reports from our java application. .rpt file is designed using CR 2008 .
The problem we have is its taking longer time to generate a report. Atleast its taking 5-6 minutes. XML file size is around 300 KB. .rpt file size is 2000 KB.
Steps involved in report generation in Java program.
1. Creating ReportClientDocument.
2.Opening ReportClientDocument( reportClientDocument.Open())
3. constructing XML datasource IXMLDataSet(xml_ds). ( setting XML and XSD)
4. setting the datasource to database controller. -- reportClientDocument.getDatabaseController().setDataSource(xml_ds, "", "")
5. then exporting the report in pdf format.
I don't know what I am doing wrong. Please advise me to improve the performance of this function.
Thanks,
Makesh

Ted,
I figured out the cause of the problem. I am using JDeveloper as my IDE thats causing the delay. When I deployed the application and ran it, it took just 30 secs for the report using "Pushing" mechanism. Thats amazing. Thanks for your support.
I have another problem. I am not sure whether to post a separate thread for this problem. Anyway I explain the problem here. If you think it needs another thread, I will post a new one.
When I use my IDE or the following command JRC runs fine and generates the reports with graphs and all.
java -classpath C:\JDK\java1.5\bin\CERT.jar;C:\oracle\JDeveloper10.1.3\jdbc\lib\ojdbc14dms.jar;C:\oracle\JDeveloper10.1.3\jdbc\lib\orai18n.jar;C:\oracle\JDeveloper10.1.3\jdbc\lib\ocrs12.jar;C:\oracle\JDeveloper10.1.3\diagnostics\lib\ojdl.jar;C:\oracle\JDeveloper10.1.3\lib\dms.jar;C:\Apps\CERTLib\log4j-1.2.8.jar;C:\Apps\CERTLib\CRLib\com.azalea.ufl.barcode.1.0.jar;C:\Apps\CERTLib\CRLib\commons-collections-3.1.jar;C:\Apps\CERTLib\CRLib\commons-configuration-1.2.jar;C:\Apps\CERTLib\CRLib\commons-lang-2.1.jar;C:\Apps\CERTLib\CRLib\commons-logging.jar;C:\Apps\CERTLib\CRLib\CrystalCommon2.jar;C:\Apps\CERTLib\CRLib\CrystalReportsRuntime.jar;C:\Apps\CERTLib\CRLib\cvom.jar;C:\Apps\CERTLib\CRLib\DatabaseConnectors.jar;C:\Apps\CERTLib\CRLib\icu4j.jar;C:\Apps\CERTLib\CRLib\jai_imageio.jar;C:\Apps\CERTLib\CRLib\JDBInterface.jar;C:\Apps\CERTLib\CRLib\jrcerom.jar;C:\Apps\CERTLib\CRLib\keycodeDecoder.jar;C:\Apps\CERTLib\CRLib\log4j.jar;C:\Apps\CERTLib\CRLib\logging.jar;C:\Apps\CERTLib\CRLib\pfjgraphics.jar;C:\Apps\CERTLib\CRLib\QueryBuilder.jar;C:\Apps\CERTLib\CRLib\webreporting-jsf.jar;C:\Apps\CERTLib\CRLib\webreporting.jar;C:\Apps\CERTLib\CRLib\XMLConnector.jar;C:\Apps\CERTLib\CRLib\xpp3.jar;C:\Apps\CERTLib\iText-2.1.5.jar -Xms256m -Xmx512m com.cert.gui.CERTMainFrame
Note: CERT.jar has all the application classes and library classes.
But when I package all these jar files in to single jar file and run the below command, it generates reports with all the features except Graphs.
java -Xms256m -Xmx512m -jar CERT.jar (OR)
java -classpath C:\JDK\java1.5\bin\CERT.jar; -Xms256m -Xmx512m com.cert.gui.CERTMainFrame
Note: CERT.jar has all the application classes and library classes
I need the above command to run successfully as I am planning to use java web start for application deployment.
Please help me to solve this problem.
Thanks,
Makesh
