XSLT transformations vs JSP (performance)

Hi,
Does anyone know of any benchmarking study that would compare performance of those 2 technologies?
Thanks for help!!!!

If there was one, I would not pay too much attention to its results. The question is so broad that it is impossible to draw any useful conclusions.

Performance of XSLT transformation

Hello everybody,
I´m trying to do some in-database XML transformations from one XML format to another with a rather complex xsl stylesheet of about 9000 lines of code which performs this transformation. At first I tested the XDK XSLT functionality by simply doing a Transformation over the JAXP API outside the Database. It performed not bad, altough the memory consumption was a little bit higher then Saxon or Xalan. After that I read about the possibilities of in-database transformation, which should consume less memory because of oracle´s xml features like scalable DOM, XML Indexing and Query Rewriting when using object relational or binary storage. So we loaded our testdata into the db (we are using 11gR2 on a test system with Intel Core2Duo @ 3GhZ and 3GB RAM), in different XML storage options (XMLTYPE CLOB, Binary, OR) and tried to do a XSLT transformation on the columns. But it isn´t working.
The db seems not to be able to cope with the transformation although the parser and processor should be the same as the off-database transformation that was working well (or am I wrong?). After half an hour we aborted because the db hadn´t finished the transformation yet (the off-db transformation of this 100KB XML took less then a second). We tried indexing the columns with XMLIndex, didn´t work out, we tried both XMLTYPE´s XMLtransform() and dbms_xslprocessor.processxsl(), same problem, the DB is working and working with no result, after some time we have to terminate. With a simple teststylesheet the transformation is doing fine but our complex stylesheet seems to be the problem.
My question is, why is the xslt performance so poorly with the complex stylesheet and why can I use the XDK Parser and Processor in an off-db transformation very efficiently but when doing the same transformation in the db it´s not working.
Hope you can help me out a little bit I´m really running out of ideas.

Hi,
The db seems not to be able to cope with the transformation although the parser and processor should be the same as the off-database transformation that was working well (or am I wrong?). No, the database built-in XSLT processor (C-based) is not the same as the XDK's Java implementation.
There's also a C XSLT processor available for external transformation and working with compiled stylesheets, it should outperform the Java implementation.
See : http://docs.oracle.com/cd/E11882_01/appdev.112/e23582/adx_c_xslt.htm#i1020191
We tried indexing the columns with XMLIndex, didn´t work out, we tried both XMLTYPE´s XMLtransform() and dbms_xslprocessor.processxsl(), same problem, the DB is working and working with no result, after some time we have to terminate. With a simple teststylesheet the transformation is doing fine but our complex stylesheet seems to be the problem.XMLIndexes won't help at all in this situation.
In my experience so far with the built-in engine, I've seen the best result when the XML document we want transform is stored as binary XML.
I don't know about the scalable DOM (or "lazy" DOM loading) feature described in the documentation, seems it doesn't support complex transformations, much like functional vs. streaming evaluation for XQuery.
Hope you can help me out a little bit I´m really running out of ideas.I'd be interested in a test case if you have the possibility (stylesheet + sample input XML). You can mail me at this address : mb[dot]perso[at]wanadoo[dot]fr
If you can't, could you describe what kind of transformation you're performing and how can I reproduce that behaviour?
Thanks.
Marc.

Help Please ! -- transform XML to HTML using xslt tag in JSP

Hello,
I have problem to do XSL transform in JSP.
I have an XSL : test.xsl
I have an XML : test.xml
In JSP I have:
<x:xslt media="html" xml="test.xml">
<x:stylesheet media="html" uri="test.xsl" />
</x:xslt>
But It doesn't work the way it suppose to. What is wrong in my code ? I followed the URL http://e-docs.bea.com/wls/docs81/xml/xml_apps.html
Thanks in advance,
Christina

Basically:
    try{
      //Setting up parameters.
      xml=new StreamSource(new File(xmlInput));
      xsl=new StreamSource(new File(xslInput));
      baos=new ByteArrayOutputStream();
      htmlResult=new StreamResult(baos);
      //Transform input(xml, xsl) onto html output.
      TransformerFactory tfactory=TransformerFactory.newInstance();
      Transformer transformer=tfactory.newTransformer(xsl);
      transformer.transform(xml, htmlResult);
      baos.writeTo(out);
      //System.err.println(htmlResult.getOutputStream().toString());
    catch(...){
    }I havent tested and I havent use this for a while, but I hope this can serve as a staring point.

Poor performance of XSLT-transformation

Hi, everyone
I`ve got report in BI-publisher based on xsl-template.
This template transforms flat xml-file in Excel file and displays the data in the likeness of a cross-tab.
Everything looks fine, but when the input file is larger than 1 MB, then the output file is formed about 10-15 minutes.
However, when the input file is less than 1 MB, I got the output file is less than 1 minute.
How i can see where is the "bottleneck"?
What i can do to improve performance of xslt-transformation?
Thanks

Hi,
Sorry that did not respond sooner.
We have gave the process of 1024 MB memory.
It`s about 4100+ records in result xml.
BIP version is 10.1.3.4 and java - 1.6.
Xsl-template and Xml you can download here
Thank you for reply =)

PL/SQL XSLT transformation problem

I am trying to perform an XSLT transformation inside a PL/SQL procedure using dbms_xslprocessor.processxsl() but I am getting the following error 'LPX-00411: unknown function name encountered'
The transformation XSL contains a java extension to preform some encoding of data and with the template containing the reference to the extension removed the transformation works fine. Does this mean that DBMS_XMLPARSER does not support java extensions in XSL or is it possible I'm just calling the function incorrectly?
I have been testing up to now using oraxsl on the command line which seemed to work fine.
Thanks,
Alan

Alan,
Are you using the right namespace for the class you want to use?

How to run the ASDoc XSLT transformation manually?

Hello there,
I am combining the XML (toplevel.xml and toplevel_classes.xml) output of several actionscript projects into
a one central XML file. I do this by first running the asdoc tool on the separate projects with the keep-xml and
skip-xsl switches set to true. I then run my own XSLT script that combines the toplevel XML files and
toplevel_classes XML files into two main files.
After that I'd like to run the actual HTML generation, as far as I know its not possible to run asdoc with certain
switches that tell it to skip the XML generation and just perform the XSLT transform immediately for a specified
toplevel.xml and toplevel_classes.xml.
Therefore I guess I have to run the XSLT tranforms from the 'templates' directory myself.
So, thus my question is, what is the exact order of XSLT transforms and for which files?
i.e. do I call class-list.xsl with toplevel_classes.xml, etc?
thanx a lot in advance,
Roland

Hey there,
yes, I understood what you meant, but even just the physical copying of the files will take a fair amount of time that I prefer to avoid
I'm getting down with ANT as we speak Its a load of trial and error, but I'll report back if I have things working.
Cheers,
Roland

Genereting JSTL tags with an XSLT transformation question

Hi there!
I have some XML datas to display in a jsp file.
XML content is of this type:
<message>
<title>A message</title>
</message>
The most elegent way to present them is to transform XML via xslt into xhtml.
(that way I can externally change with ease the message formatting output without changing the jsp)
For that, I use the cool tag
<x:transform>
on each xml file i want to display (with x:foreEach)
The output produced for each xml file is:
<div class="message">
<h2>A message</h2>
</div>
My problem is now that I want to include custom tags in the generated content!
For exemple:
<div class="message">
<h2>A message<c:out ...></h2>
</div>
My question is:
how can I make that xslt generated tag to be executed???
Since it is the product of an xslt transformation ,I suppose it won't be executed at all...
Advices greatly appreciated! :)

I'm not sure I understand what you mean when you say "how can I make that xslt generated tag to be executed???"
You've got your XML input and the XSL-T stylesheet that will transform the XML input into an XHTML stream containing JSTL tags.
I'm assuming that you're going to ask a servlet to pass the XML input to the XSL transformer and get the XHTML output stream. Once you have that, the servlet will write the XHTML to the HTTP response output stream, where it'll be rendered by the browser.
I think the key is to make sure that you tell the browser that response type is a JSP (that's the only document type in which it makes sense to put JSTL tags). When the browser gets that JSP, it'll treat it like any other: generate .java code, compile that to a .class file, and then render.
I'm not sure about efficiency, but it sure is an elegant solution. - MOD

Configuring the XSLT transformation service

I need to use XSL-T 2.0 in a service. The documentation for XSLT Transformation says that an alternate service provider can be used. It says I need to supply a string value that represents the fully qualified name of the Java class to use for performing the XSLT transformation, such as org.apache.xalan.xslt.XSLTProcessor. The Java class used must extend javax.xml.transform.TransformerFactory and must be available to the class loader of the LiveCycle ES server.
The Saxon XSL-T engine supports the required interface, but I have not been able to install it successfully. In theory, it is a component that can be installed from the Components panel, but when I try that I receive the message "An error occurred. Please check the Eclipse error log for details". I have not been able to locate the error log.
Any assistance greatly appreciated.
--RKW

Thanks for the assistance. That turns out to be the right advice. If you want to use the Saxon processor, you need to put the following jars in the server\all\lib folder:
saxon8.jar
saxon8-dom.jar
--RKW

Automatic insert of xmlns:xsl during XSLT transformation

I am using the xmlparserv2.jar of dated "12/10/00" to perform a XSLT transformation. I need to insert a xml:space="preserve" attribute to a generated tag. However, there is an addition attribute added : xmlns:xml="http://www.w3/org/XML/1998/namespace". How can I suppress the generation of this attribute ?
Here is my XML :
<?xml version = '1.0' standalone = 'no'?>
<COLDdoc>
<Page template="bkgnd1" num="1">
<Line num="1"> CN011A021C 1A021</Line>
<Line num="2"> 1954.90 7713.36</Line>
</Page>
</COLDdoc>
My XSL is :
<?xml version = '1.0' standalone = 'yes'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" indent="no" doctype-system="svg-20000303-stylable.dtd"/>
<xsl:template match="Line">
<text>
<xsl:attribute name="x">0</xsl:attribute>
<xsl:attribute name="y">
<xsl:value-of select="@num*10"/>
</xsl:attribute>
<xsl:attribute name="xml:space">preserve</xsl:attribute>
<xsl:value-of select="."/>
</text>
</xsl:template>
</xsl:stylesheet>
The result XSLT Transformation :
<?xml version = '1.0' encoding = 'UTF-8'?>
<!DOCTYPE text SYSTEM "svg-20000303-stylable.dtd">
<text x="0" y="10" xmlns:xml="http://www.w3/org/XML/1998/namespace" xml:space="preserve"> CN011A021C 1A021</text>
<text x="0" y="20" xmlns:xml="http://www.w3/org/XML/1998/namespace" xml:space="preserve"> "> 1954.90 7713.36</text>

Hi Greg,
please try it with the following (just slightly) modified transformation (works fine for me):
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
               xmlns:asx="http://www.sap.com/abapxml"
               xmlns:sap="http://www.sap.com/sapxsl"
               version="1.0">
<xsl:strip-space elements="*"/>
<xsl:template match="/PEXR2002/IDOC">
    <asx:abap version="1.0">
      <asx:values>
        <HEADER_DATA>
          <SNDPRN>
            <xsl:value-of select="EDI_DC40/SNDPRN"/>
          </SNDPRN>
          <BGMREF>
            <xsl:value-of select="E1IDKU1/BGMREF"/>
          </BGMREF>
          <MOABETR>
            <xsl:value-of select="E1IDKU5/MOABETR"/>
          </MOABETR>
          <CREDAT>
            <xsl:value-of select="EDI_DC40/CREDAT"/>
          </CREDAT>
          <DATUM>
            <xsl:value-of select="E1EDK03/DATUM"/>
          </DATUM>
        </HEADER_DATA>
      </asx:values>
    </asx:abap>
</xsl:template>
</xsl:transform>
I recommend to test all transformations that you define on a sample source and check the output. If you apply your original transformation you would see that it basically doesn't select anything and therefore you just get an XML document with the field names but no values.

Updating XML prior to XSLT transformation

I am attempting to convert an XML document using XSLT but I need to transform it a bit beforehand. Does anyone have a suggestion as to how to do this?
Below is the logic that will transform the XML directly from the file, but I need to manipulate it first.
Thanks in advance.
Patti
import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamSource;
import javax.xml.transform.stream.StreamResult;
import java.io.*;
public class Transform {
     * Performs an XSLT transformation, sending the results
     * to System.out.
    public static void main(String[] args) throws Exception {
        if (args.length != 2) {
            System.err.println(
                "Usage: java Transform [xmlfile] [xsltfile]");
            System.exit(1);
        File xmlFile = new File(args[0]);
        File xsltFile = new File(args[1]);
        // JAXP reads data using the Source interface
        Source xmlSource = new StreamSource(xmlFile);
        Source xsltSource = new StreamSource(xsltFile);
        // the factory pattern supports different XSLT processors
        TransformerFactory transFact =
                TransformerFactory.newInstance();
        Transformer trans = transFact.newTransformer(xsltSource);
        trans.transform(xmlSource, new StreamResult(System.out));
}

The first scenerio is what I intended. Since I posted my question I realized that I can manipulate the string and then create a StringSource passing a StringReader like so:
StringReader src = new StringReader(xmlStr);
StringWriter target = new StringWriter();
currentTransformer.transform(new StreamSource(src),
                             new StreamResult(target));Thanks.

Tags not printed when outputting XML after XSLT transformation

Hi!
I want my to perform an XSLT transformation on requests to my web service.
This is the style of a typical request:
<app:aRequest xmlns:app="http://myNamespace">
<app:firstTag>value1</app:firstTag>
<app:secondTag>value2</app:secondTag>
<app:thirdTag>value3</app:thirdTag>
</app:aRequest>I want to transform it into something like this:
<app:aRequest xmlns:app="http://myNamespace">
<app:firstTag>A hard coded, completely different value!</app:firstTag>
<app:secondTag>value2</app:secondTag>
<app:thirdTag>value3</app:thirdTag>
</app:aRequest>To do that, I use the following XSLT:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:app="http://myNamespace">
<xsl:template match="/">
<app:aRequest>
<app:firstTag>A hard coded, completely different value!</app:firstTag>
<app:secondTag><xsl:value-of select="app:aRequest/app:secondTag" /></app:secondTag>
<app:thirdTag><xsl:value-of select="app:aRequest/app:thirdTag" /></app:thirdTag>
</app:aRequest>
</xsl:template>
</xsl:stylesheet>And I use the following code to execute the transformation:
public Object unmarshal(Source source) throws XmlMappingException, IOException {
TransformerFactory factory = TransformerFactory.newInstance();
    // Does this factory support SAX features?
    if(factory.getFeature(SAXSource.FEATURE)) {
      SAXTransformerFactory saxTransformerFactory = (SAXTransformerFactory)factory;
    // Read xslt file.
    InputStream inputStream = getClass().getResourceAsStream("/META-INF/xsltTransformation.xsl");
    if(inputStream == null) {
      throw new RuntimeException("No XSLT transformation file present at " + location);
    Templates xsltOutputTemplate = saxTransformerFactory.newTemplates(new StreamSource(inputStream));
    Transformer transformer = xsltTemplate.newTransformer();
    // Perform transformation.
    StringWriter stringWriter = new StringWriter();
    StreamResult result = new StreamResult(stringWriter);
    transformer.transform(source, result);
    // Print result.
    String xmlString = stringWriter.toString();
    System.out.println(xmlString);
    // Proceed with unmarshalling.
    StringReader stringReader = new StringReader(xmlString);
    StreamSource transformedSource = new StreamSource(stringReader);
    return oxMapper.getUnmarshaller().unmarshal(transformedSource);
}However, the System.out.println(xmlString); produces the following result:
<?xml version="1.0" encoding="UTF-8"?>
value1
value2
value3The tags are not printed and the hard coded value is not present.
What am I doing wrong? Please help!

Following up on what the good Dr said,
Are you sure that you are using the stylesheet that you think you are?
I tried your stylesheet and input and got more or less what you wanted and not what you actually got.
Note that I did not use your code.

Hi Priya,
you can try with the below,
1) Create a local ITAB with the structure of the XML,
TYPES: BEGIN OF t_data,
        projectid           TYPE char30,
        stage               TYPE char30,
        country             TYPE char30,
        region              TYPE char30,
        teamleader          TYPE char30,
        teamleaderfirstname TYPE char30,
        teamleaderlastname TYPE char30,
        actiontype          TYPE char30,
       END OF t_data.
2) Create an XSLT prog in "STRANS" with the below code,
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:sap="http://www.sap.com/sapxsl" version="1.0">
<xsl:strip-space elements="*"/>
<xsl:template match="/">
<asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0">
<asx:values>
<L_DATA>
<xsl:apply-templates select="//projectInfo"/>
</L_DATA>
</asx:values>
</asx:abap>
</xsl:template>
<xsl:template match="projectInfo">
<conceptRevDecisionXml>
<PROJECTID>
<xsl:value-of select="projectId"/>
</PROJECTID>
<STAGE>
<xsl:value-of select="stage"/>
</STAGE>
<COUNTRY>
<xsl:value-of select="country"/>
</COUNTRY>
<REGION>
<xsl:value-of select="region"/>
</REGION>
<TEAMLEADER>
<xsl:value-of select="teamleader"/>
</TEAMLEADER>
<TEAMLEADERFIRSTNAME>
<xsl:value-of select="teamleaderfirstname"/>
</TEAMLEADERFIRSTNAME>
<TEAMLEADERLASTNAME>
<xsl:value-of select="teamleaderlastname"/>
</TEAMLEADERLASTNAME>
<ACTIONTYPE>
<xsl:value-of select="actionType"/>
</ACTIONTYPE>
</conceptRevDecisionXml>
</xsl:template>
</xsl:transform>
3) Call the transformation as shown below,
CALL TRANSFORMATION zxslt_project ---> "Name of the XSLT prog created above
SOURCE XML l_xml_str                           ---> Source XML string
RESULT l_data = l_data.                          ---> ITAB as in step 1 above

Error when applying a XSLT transformation: No valid XSLT pro

Dear All,
I am getting following error when opening the "General Supplier Data" from Pre-Select Supplier.
Error Message: "Error message: Error when applying a XSLT transformation: No valid XSLT program supplied"
I have already read the related threads on SDN and checked the SAP Note 883896 and others. Even tried running the program UXS_DEL_NAVIGATION_NODE and UXS_ADD_MISSING_XSLT_NAME. But not able to solve the issue.
Kindly Help.

Hi Masa,
Thanks for reply. I have checked this note. As note suggests, S_DEVELOP auth object is assigned to the user. and it has value *.
Do I need to check anything else?

UTF-8 encoding in XSLT transformation

Hello,
I have a problem with a transformation of an ABAP structure into XML. I use the XSLT transformation for this.
My XSLT starts like this:
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:strip-space elements="*"/>
<asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0">
    <asx:values>
I tried many settings I could find posted on the internet, but I did not find one that would allow encoding to UTF-8.
It always encodes to iso-8859-1 which my interface partner cannot read.
Does anyone know a way to force encoding to UTF-8?
Adding a command like <xsl:output encoding="utf-8"/> did not help.
Thanks a lot!
       J. Euler

Hello!
I think I just solved the problem taking a different approach.
In a note here on SDN, a guy from SAP wrote, that the SAP XSLT processor is not able to code anything but the system's default to a string, BUT that it is able to code it to an xstring.
All I did now is add the tag
<xsl:output encoding="utf-8" indent="yes" method="xml"/>
to my xslt program and change the coding in the program accordingly.
The program code is now:
DATA: tempxstring TYPE xstring,
        temp_length TYPE i,
        conv      TYPE REF TO cl_abap_conv_in_ce.
CLEAR tempxstring.
TRY.
      CALL TRANSFORMATION
          zxxje_tst_xslt
        SOURCE omsregdatawebservice = wa_data
        RESULT XML tempxstring.
    CATCH cx_sy_conversion_base64.
    CATCH cx_sy_conv_illegal_date_time.
ENDTRY.
IF tempxstring IS NOT INITIAL.
    CLEAR: conv, temp_length, string_xml_result.
    conv = cl_abap_conv_in_ce=>create( input = tempxstring ).
    conv->read( IMPORTING data = string_xml_result len = temp_length ).
ENDIF.
Thanks anyways for all your help!
