Problem in transforming XML to string using XSLT

Hi there,
I have a R/3 -> XI -> WebService scenario where the message from XI to webservice needs to be sent in document/wrapped mode (the message xml must be embedded in a string element) and this message needs to be digitally signed.
We are using another webservice to sign the messages, also with the message being sent in a string. To transform the XML's into string and vice-versa, we are using XSLT (/people/michal.krawczyk2/blog/2005/11/01/xi-xml-node-into-a-string-with-graphical-mapping).
The problem is that both the signer and the final webservice understand the special characters (like '<', '>', '&', '"' etc) in one way but the XSLT generates them in another way. For example, the character '<', in both webservices, is returned as "<" but the XSL Transformation results in "<".
The problem now is that our messages are always being rejected because the signature is not being recognized as true, though we are almost 100% sure that it's being done correctly. The only possibility to the error that we found is this character mapping being done differently.
So, it's like this:
XI sends string to signer as "<"
XI receives string from signer as "<"
XI processes the message
XI sends string to webservice as "<"
XI receives string from webservice (containing error message) as "<"
Is there a way of making the XSLT to return "<" instead of "<"?
Thanks in advace,
Henrique.

For Java Mapping, you can refer this-

In Java Mapping, in the startdocument event , you need to check for the specialchars, and just repalce the value required.
But, what i am thinking is , just try with Java functions inside the XSLT mapping instead of going for Java Mapping. You can call java functions from the XSLT. So before the document starts pasring, you need to replace the special characters. I did not try in XSLT like this.
For this , you can think with this e.g

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,

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.

Problems in transforming XML to HTML using HP-UX with Netscape Enterprise Server 4.0 sp3

Hi,
Has anyone ever had any problem using XML in NES 4.0 sp3?
I'm using the libraries com.sun.xml.parser, com.sun.xml.tree, javax.xml.transform.
The html is being created but is not being returned.
(it is not showed in browser)
This same xml application works well in Solaris with Iplanet Web Server 4.1, but it is not working in HP-UX with Netscape Enterprise Server 4.0 sp3.
I'm entirely lost. I don't know if there is a bug in this version (NES 4.0) or if I need other xml libraries or it is a problem of JRE version.
Any comments will be appreciate.
Thanks

Hi,
Last year we built a complete new website, based on XML/XSL.
We assumed all browsers would cope with XSL by now, but that was far to optimistic.
Our company planned to launch the new site this december, but XSL is giving us some major problems:
*** All our customers are obliged to use Internet Explorer 4/5.x. Some don't like that at all: they stick to Netscape.
*** IE users have to download and install the MS-XSL parser. At our pilotsites this is giving a lot of trouble and frustration.
I heard that it is possible to do the parsing at the serverside, using XSLT, creating HTML.
HOW CAN WE INSTALL / IMPLEMENT THIS OPTION IN OUR CONFIGURATION?

Problem in transforming xml to html using xsl

want to embed some html code also in the data node.But when I get the html it simply writes as it is.That statement contradicts:
In real application i will be getting data containg html tags.I want the parser to read that data as simple text. Both cannot be true. You either want the HTML to not be parsed or you want the transformer to deal with it. Which one?

XML to ABAP Using XSLT

Hello friends,
    I am trying a ABAP program (posted on SDN) to convert XML into ABAP (internal table) and not having any luck. Either it is my table/structure declaration or XSLT. Could any of you experts give me a hand with it please?
Thanks in advance..but points on help!
Here is my XML:
And my ABAP program:
REPORT ZTESTXMLREAD.
TYPE-POOLS: abap, ixml.
class cl_ixml definition load.
TYPES: BEGIN OF t_dc40,
         docnum(17) TYPE C,

         emktx      TYPE t_emkt,
       END   OF t_emrm.
TYPES: BEGIN OF t_mm,
         dc40   TYPE t_dc40,

      err_string TYPE string.
PARAMETERS: pa_file TYPE char1024 DEFAULT 'c:Test.XML'.
START-OF-SELECTION.
Creating the main iXML factory
    l_ixml = cl_ixml=>create( ).
Creating a stream factory
    l_streamfactory = l_ixml->create_stream_factory( ).
Creating input stream
    l_istream = l_streamfactory->create_istream_uri( 'file://c:Test.xml' ).
here we use the CALL TRANSFORMATION method which calls
TRY.
    CALL TRANSFORMATION ZTestXSLT
      SOURCE xml l_istream
      RESULT xml_output = it_airplus
catch any error, very helpful if the XSLT isn't correct
    CATCH cx_xslt_exception INTO xslt_err.
    err_string = xslt_err->get_text( ).
    WRITE: / 'Transformation error: ', err_string.
    EXIT.
ENDTRY.
setting a breakpoint to watch the workarea
by the internal table "it_airplus"
     break-point.
LOOP AT it_airplus INTO wa_airplus.
ENDLOOP.

Thank you Durairaj, as a matter of fact my program is based on your post (one that you pointed me to). For whatever reason I'm not having luck figuring it out (may be just a bit of work pressure) could you please hlep me a bit more by pointing me to where in my program code/xslt I'm going wrong? I somehow feel that it could be my table structure or xslt.
I would really appreciate it!
Thanks again,

How to find XSD file? XML to ABAP using XSLT convertor

Hi Gurus,
I am trying to convert an XML file to ABAP internal tables using an XSLT transformation. I used the code posted by Durairaj (XSLT program Y_XML_2_ITAB_SIMPLE as mentioned in the link: [Y_XML_2_ITAB_SIMPLE|Parse data to Internal Table;) and the code worked fine.
My XML file structure is different, and when I try to modify the code for my purposes I got stuck. While changing the XML file strings in the report, I am unable to replace the tag xsi:noNamespaceSchemaLocation="invoice_btm.xsd" correctly. I am also not sure what this file "invoice_btm.xsd" does and where it is stored. When I remove the tag, I get other errors and cannot proceed ahead.
Can you please advice as to how I should proceed? Also, where can I see the XSD file? can I add a XSD file for my own XML? Or, is there a way to eliminate the need for an XSD file altogether?
Thanks in advance.
Regards,
Shailesh.

Generating CDATA containing XML-like text using XSLT Mapper in OFM 11g

Hi,
One of our partners requires XML to be sent as XML string inside a CDATA section. The use of "real" XML is not an option at the moment. We try to generate something like the following using XSLT/XSLT Mapper in SOA Suite 11g:
<element>
<![CDATA[
<supplierElement1>
<supplierElement2>
etcetera
<supplierElement2>
</supplierElement1>
]]>
</element>
We've tried the following two approaches, so far unsuccessful:
<xsl:template match="/">
<inp1:singleString>
<inp1:input>
<xsl:text disable-output-escaping="yes"><![CDATA[test]]></xsl:text>
</inp1:input
</inp1:singleString>
</xsl:template>
resulting in:
<inp1:singleString xmlns:inp1="http://xmlns.oracle.com/singleString">
<inp1:input><![CDATA[test]]></inp1:input>
</inp1:singleString>
and:
<xsl:output method="xml" indent="yes" cdata-section-elements="input"/>
<xsl:template match="/">
<inp1:singleString>
<input>test</input>
</inp1:singleString>
</xsl:template>
resulting in:
<inp1:singleString xmlns:inp1="http://xmlns.oracle.com/singleString" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<input>test</input>
</inp1:singleString>
Does anyone know how to generate the CDATA section declaratively (within XSLT/XSLT Mapper), without resorting to custom code and parsing as we have to do now?
Thanks!
Ronald

How to display transformed XML in flex? xslt processor w/o javascript?

can anybody has idea how i can ignore all this value using XSLT

I just dont understand why factory.setIgnoringElementContentWhitespace(true) did not work.That only does something if the XML has a DTD that enables it to know what whitespace can be ignored and what is significant. The API documentation for the method refers you to this document:
http://www.w3.org/TR/REC-xml#sec-white-space

How to get the WHOLE xml document inside a string using XSLT mapping

Hi folks,
I have a deep xml structure that I want to embed as body, tags included, in a mail message (not as an attachment).
I'm trying to use Michal's method in this blog
/people/michal.krawczyk2/blog/2005/11/01/xi-xml-node-into-a-string-with-graphical-mapping
However, I can't get it to deliver the entire structure instead of just specific elements.
Any help is greatly appreciated,
Thanks,
Guy

Ashok,
I was able to work it out for my case.
This XSL......
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<inside>
<namestring>
<xsl:text disable-output-escaping="yes"><![CDATA[<![CDATA[]]></xsl:text>
<xsl:copy-of select="outside/name/*"/>
<xsl:text disable-output-escaping="yes"><![CDATA[]]]]></xsl:text>
<xsl:text disable-output-escaping="yes"><![CDATA[>]]></xsl:text>
</namestring>
</inside>
</xsl:template>
</xsl:stylesheet>
...will transform this input....
<?xml version="1.0" encoding="UTF-8"?>
<outside>
<name>
<nameone>name1</nameone>
<nametwo>name2</nametwo>
<namethree>name3</namethree>
</name>
</outside>
...and put the whole lot into the CDATA element.
Hope this helps you,
Guy

Convert XML Node to String using XSLT

Hi,
Perhaps this has been discussed before. But i am looking at creating a XSLT mapping to take the entire inbound message and put it into a single node of the target.
Is there a way?
Thanks in advance
Regards
Venkat

Hi Shankar,
I have a input XML <root><a></a></root>
I have a target <tgt><b></b></tgt>
I need to have the target xml as
<tgt><b>&lessthansign;root&greaterthansign;&lessthansign;a&greaterthansign;&lessthansign;/a&greaterthansign;&lessthansign;/root&greaterthansign;</b></tgt>
Using the XSLT that you mentioned
I am getting the format
<tgt><b><root><a></a></root></b></tgt>
Now the consumer of this message expects the data in the first type of format
That is where i am getting stuck
Thanks and Regards
Venkat

SAP 4.7 XML data exchange using XSLT

Hello All,
Hopefully the right place to post such article but here goes any way.
My project involves producing XML files and then reading them back into to SAP internal tables. I am ok with writing SAP data to external XML file but reading it back in is causing a lot of head scratching.
I am able to double click the XML file and it launches Ok in Internet Explorer.
I am also able to debug the xslt file from within SE80 and the correct output is displayed.
However, where I am trying to read the contents of the xml file via the Call Transformation procedure call my output table is not getting populated but instead I am recieving an error message saying the following is not correct:
xmlns:sapxsl="http://www.sap.com/sapxsl
but the above line is placed automaticlly in the XSLT when you create a new one from within SE80.
I am new to SAP ABAP development so not sure what's exactly wrong.
Any help on this issue will be greatfully appreciated. Thanks in Advance,
Wasif

Problems with some web parts when using XSLT

I have a page on which I have several web parts. Some web parts are custom while others are OOB and only XSLT is applied on them.
I am using 2 WFEs with NLB. Problem is when I do iisreset on one of the WFE then the OOB web parts with XSLT start giving error. You know the standard error "corelation ID....bla bla bla". Anyway the error automatically goes away after a 2, 3 minutes.
So basically if I do iisreset or stop the iis, and then load that page, then all custom web parts load fine except those OOB web parts with XSLT. And then they too start working fine after 2, 3 minutes if I reload page.
What could be the reason for that? Looks like some service on which XSLT depends take time to load!? And once that service is loaded then they start working fine? Or it could be due to distributed cache or something!?

Hi Frank,
Which version of the SharePoint 2010 did you use?
In June 2011 CU code was added to the DataFormWebPart (which is used to display list data) that if an XSLT transform took longer than 5 seconds, a StackOverflowException was thrown. This was done to avoid
a potential Denial Of Service attack on SharePoint if crafted XML could be sent that would continually clog up the XSLT, thereby stopping pages from rendering.
In August 2011 CU the transform "timeout" was reduced from 5 seconds to 1.
So, any list with XSLT that takes longer than 1 second to parse in an XSLT transform goes *boom*.
After you perform an IIS reset , the cache of the page was cleared and you encountered the error. Once the page is cached, there is no error.
You can try to set up XSLT Timeout with the following PS commands:
$farm = Get-SPFarm
$farm.XsltTransformTimeOut = 5
$farm.Update()
