Mobile XML transformation with MS or Java parser

Dear all,
I would like to set up an easy development environment for Mobile XML. For this reason, I would like to use a text editor (like emacs or notepad), and apply the Oracle 9iAS Wireless stylesheet (XSL file) to the Mobile XML with Internet Explorer parser.
This works fine for a such file :
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<?xml-stylesheet type="text/xsl" href="TINY_HTML.xsl"?>
<SimpleResult>
     <SimpleContainer>
     </SimpleContainer>
</SimpleResult>
but does not work for the following one :
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<?xml-stylesheet type="text/xsl" href="TINY_HTML.xsl"?>
<SimpleResult>
     <SimpleContainer>
          <SimpleMenu>
               <SimpleTitle>TP 9iAS Wireless</SimpleTitle>
          </SimpleMenu>
     </SimpleContainer>
</SimpleResult>
I have tried different XML/XSL parsers (MS, Java, XML Spy,...) but I got each time the same error message : "XSL parser stack overflow".
Does anyone know a solution for this problem ?
Thanks !
Fabrice.

I am not sure what the issue is, however within the next week or so, we will be offering an SDK on OTN with a small footprint (30MB) dev environment for Oracle9iAS Wireless. You will be able to use any IDE or text editor you wish.

Xml transformation with java

Hi, I am new to java, and was looking for some java code to accomplish the following:
I have an XML file, and a target XML schema. I also have a mapping schema, that maps the source xml file attributes with the target schema attributes.
I want to read the input xml file, and then reformat it to conform to the output xml schema(validated).
Will appreciate if someone can point me to code for a similar problem .....!

Transform the input xml to an XML document which conforms to the target schema with a XSLT.

Hi,
I am facing a problem regarding validation of xml file with DTD tag in it.
I have disabled the parser through setValidating(false) method.
xml file is not parsed in JRE 1.5.but it is parsed in JRE 1.6.
Why this is showing such a behavior?
I have used xerces 2.9.0,xml-api.jar and other jar regarding XML api but still it is giving error.
please help me.
please provide a jar file name or its issue resolution in jre 1.5 or 1.4.

thanks for your prompt reply.
I required that it should be completely disabled in jre 1.5(jdk1.5 or 1.4).
I am using DOM Parsing.I have currently disabled with follwowing method,
builderFactory.setValidating(false);
builderFactory.setFeature("http://xml.org/sax/features/validation",
     false);
     builderFactory.setFeature("http://apache.org/xml/features/nonvalidating/load-dtd-grammar", false);

in 1.6 it is working fine but I required that i have to disabled it.but it is giving a error in jre1.5.
Exception in thread "main" java.lang.AbstractMethodError: javax.xml.parsers.DocumentBuilderFactory.setFeature(Ljava/lang/String;Z)V
I just want to disable the parsing in jdk version 1.5 or 1.4

XML transformation with BusinessObjects Data Services

Hi,
We have a legacy web service based on JAX-RPC and the data retrieved from this service does not conform to the schema generated, so there's a need to retrieve the data generically(a complete XML body is returned in a varchar field) and then parse the data inside and assign to individual fields. For a limited period of time until this service is phased out, we need to use this service to retrieve data for some ETL processes. Does BusinessObejcts Data Services offer me a way to implement a custom transformation (for example, a custom Java parser code)? If it does, please advise how to find the relevant how-to guides, or any other means to get the data.
Kind regards,
S. Gökhan Topç

Hi,
DS offers the possibility to run a program at the end of an ETL job. So you could write your java code and let DS run it.
Maybe thats sufficient.
But i would recommend you check the "Enterprise Information Management" Forum, there are the DS Gurus located.
Regards
-Seb.

XML-file with prefix in Java importing

Hello,
I have one XML-file with prefix "wf" like this:
   <wf:data>
           <wf:name>NAME</wf:name>
           <wf:description/>
           <wf:creation_time>0001-01-01T00:00:00</wf:creation_time>
           <wf:user wf:ref=""/>
           <wf:properties/>
   </wf:data>the Java-Code like this:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
          factory.setNamespaceAware(false);
          XPath xpath = XPathFactory.newInstance().newXPath();
          String expression = "./data/name/text()";
          InputSource inputSource = new InputSource("workflow.xml");
                String result = xpath.evaluate(expression, inputSource);the Java-Code works well, if the prefix does not exist, otherwise I could not get any result. Could somebody please help me?
Thank you
Sunny

I have defined the namespaceI didn't see that in your original post.
I notice that your XPath expression doesn't include the namespace prefixes and you don't tell it how to map the prefixes to the namespace URIs. I am not sure whether calling factory.setNamespaceAware(false) makes it unnecessary to do that. I wouldn't count on it.

XML Validation with XSD in java mapping

Hi experts,
I have created an interface to send differents messages between bussines system, the bussiness system receiver is put in the message, to get this value I have a configuration file indicating the path of this field for each message type. In a java mapping I transform the message sent in this structure:
<document>
<message>HERE THE MESSAGE AS STRING</message>
<parameters>
<sender>HERE SENDER BUSSINESS SYSTEM</sender>
<receiver>HERE RECEIVER BUSSINESS SYSTEM</receiver>
</parameters>
</document>
the messaging interface works fine, but now I have to validate the XML vs XSD. I need doing in a java mapping because the messaging interface send the message and a email to sender in error case.
To do this validation I have implemented two java mappings that works fine in my local, the first way is with class Validator of java 5, but my system PI 7.1 return an error with this class. The second way is with SAX parse:
String schema = "XXXXXxsd";
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
docBuilderFactory.setNamespaceAware(true);
docBuilderFactory.setValidating(true);
docBuilderFactory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaLanguage","http://www.w3.org/2001/XMLSchema");
InputStream is = this.getClass().getClassLoader().getResourceAsStream(schema);
docBuilderFactory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaSource",is);
in my local works fine but in PI always return OK never fail.
For this moment the schema is hardcoded to do proofs, in the future will be loaded from my configuration file.
Any idea?
Thanks in advance
Jose

hi Jose,
PI 7.1 has a built in feature available called XML vaidations ..
your source xml can be validated against a XSD placed at a specific location on the PI server..
validation can be performed at adapter/integration engine

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);

Please help me....

It depends on your jre version if you have jre 1.4 .
You can get your TransformerFactory instance using javax.xml.transform.TranformerFactory.newInstance() directrly.
If your jre version is higher than *1.4* than try to locate this class in your rt.jar in jre lib directory.
When you found that class replace your code
System.setProperty("javax.xml.transform.TransformerFactory","your desired TransformerFactoryClass") than run the code you wont find that error again.
If you want some details copy and paste your error in google search you will found same problems posted by different programmers on forums however i have seen them before. Hope this help. Sorry if i have misunderstood your problem.

Still problems serializing xml-docs with xml-parser for java v2.0.2.7

Hi !
I'm using the Oracle XML Parser 2.0.2.7.0 and get some problems when serializing the XMLDocument.
In one class (DOMOut) I parse a xml-file with the oracle.xml.parser.v2.DOMParser, then obtain the XMLDocument and write it to System.out
In another class (DOMIn) I fetch the XMLDocument from System.in, search for a given Element and print it's TextValue (if existing) to System.out
That is where the error occurs.
I get the XMLDocument from System.in but the returning NodeList from doc.getElementsByTagName() is empty. [nl.getLength()==0] even if it shouldn't be.
Look at this code and output:
[DOMOut]
DOMParser parser = new DOMParser();
parser.parse(url);
XMLDocument doc = (XMLDocument)parser.getDocument();
ObjectOutputStream out = new ObjectOutputStream(System.out);
out.writeObject(doc); out.flush();
[DOMIn]
ObjectInputStream in = new ObjectInputStream(System.in);
XMLDocument doc = (XMLDocument)in.readObject();
doc.print(System.out);
NodeList nl = doc.getElementsByTagName("Name");
System.out.println("Length of NodeList: "+nl.getLength());
if (nl.getLength()==0)
System.out.println(argv[0] + ": not in this document!");
else {
XMLNode node = (XMLNode) nl.item(nl.getLength()-1);
System.out.println(node.getNodeName() + ": " + (node.getFirstChild()).getNodeValue());
This is the relevant code.
I javac both classes and then do this:
java DOMOut xmltestfile.xml > xx
java DOMIn Name < xx
And get this as output:
<?xml version = '1.0'?>
<!DOCTYPE course [
<!ELEMENT course (Name,Dept,Instructor,Student)>
<!ELEMENT Name ((#PCDATA)*)*>
<!ELEMENT Dept ((#PCDATA)*)*>
<!ELEMENT Instructor (Name)>
<!ELEMENT Student (Name)*>
]>
<course>
<Name>Calculus</Name>
<Dept>Math</Dept>
<Instructor>
<Name>Jim Green</Name>
</Instructor>
<Student>
<Name>Jack</Name>
<Name>Mary</Name>
<Name>Paul</Name>
</Student>
</course>
Length of NodeList: 0
Name: not in this document!
Has anyone an idea?
If I do all this stuff without serializing it works.
If I do not search for argv[0], but the string "Name" it fails.
If I do search for "*" it works fine!
I'm very confused could anybody please help me a bit??
Stefan.

XSL problem with javax.xml.transform.sax.SAXTransformerFactory

Dear sirs,
I use SAXTransformerFactory in order to transform a Hashtable to SAX Event and apply a XSL.
I try this code with the lastest version of apache parser.
It run well.
But, I put this software to WEBLOGIC 6.2 server and no run.
this check is true:
          if (transFact.getFeature(javax.xml.transform.sax.SAXTransformerFactory.FEATURE)&&transFact.getFeature(javax.xml.transform.sax.SAXSource.FEATURE))
Some one can help me.
Thank in avance
The code:
java.io.ByteArrayOutputStream bout = new java.io.ByteArrayOutputStream();
          com.cajarural.xml.HashtableParser parser = new com.cajarural.xml.HashtableParser(hashtable);
          // Codigo para el TansformerHandler
          // set the destination for the XSLT transformation
               javax.xml.transform.TransformerFactory transFact = javax.xml.transform.TransformerFactory.newInstance();
               if (transFact.getFeature(javax.xml.transform.sax.SAXTransformerFactory.FEATURE)&&transFact.getFeature(javax.xml.transform.sax.SAXSource.FEATURE))
javax.xml.transform.sax.SAXTransformerFactory saxTransFact = (javax.xml.transform.sax.SAXTransformerFactory) transFact;
javax.xml.transform.sax.TransformerHandler transHand = saxTransFact.newTransformerHandler(templates);
transHand.setResult(new javax.xml.transform.stream.StreamResult(bout));
parser.setContentHandler(transHand);
// attach the XSLT processor to the           parser.parse();
          return new String(bout.toByteArray());

put Xalan in your war file then try using this kind of commands:     System.setProperty("org.xml.sax.parser", "org.apache.xerces.parsers.SAXParser");
System.setProperty("javax.xml.parsers.SAXParserFactory", "org.apache.xerces.jaxp.SAXParserFactoryImpl");
System.setProperty("javax.xml.parsers.DocumentBuilderFactory", "org.apache.xerces.jaxp.DocumentBuilderFactoryImpl");
System.setProperty("javax.xml.transform.TransformerFactory", "org.apache.xalan.processor.TransformerFactoryImpl");This tells JAXP what implementations it should use without even asking your administrator to modify the WebLogic setup...
It's what I've done with the WLS7.0 server I am using ;-)

} catch (IOException ioe) {
// I/O error
ioe.printStackTrace();
Any help would be greatly appreciated.

I don't know that this is true, but i think the problem is the classpath.
The runtime has his own parser. This parser is befor your xalan.lib in the classpath and the
parser from the runntime don't support namespace.
Try Tomcat 4.

Xml dom with pl/sql or java

Hi,
For increase speed an procedure with xmldom, wich langage can I use ? pl/sql or java
Thanks
Ben

I also recall readings somewhere how Oracle have coded the database packages into native C to boost performance, but for the life of me I can't recall where it was now.
I've not done any Java parsing work, but I have been using PL/SQL to parse XML Schema documents (which are in effect XML documents so there's no difference there really). I found that all I needed to be able to parse the XML schema so that I could navigate through the document and carry out my own processing was the use of the DBMS_XMLDOM package. This allowed me to navigate from the root element down through the siblings and children elements and extract the attributes and any data that was required on the way.
The Oracle PL/SQL Packages and Types Reference details all the available built-in packages sufficiently well.

Generation of Xml file with java output

Hi i m new to xml and java combination. I have a name value pair kind of output returning from java program. I want to generate the new xml file with the data. Could some one help me out in generating xml file with the data. Could anyone send me the java code that does this task.

Let me know which parser are you using currently for reading xml files so that i assist you. For now, you can refer to STAX Parser API under this link

Parsing XML string with XPath

Hi,-
I am trying to parse an XML string with xpath as follows but I am getting null for getresult.
I am getting java.xml.xpath.xpathexpressionexception at line where
getresult = xpathexpression.evaluate(isource); is executed.
What should I do after
xpathexpression = xPath.compile("a/b");in the below snippet?
Thanks
String xmlstring ="..."; // a valid XML string;
Xpath xpath = XPathFactory.newInstance().newPath();
xpathexpression = xPath.compile("a/b");
// I guess the following line is not correct
InputSource isource = new inputSource(new ByteArrayInputStream(xmlstring.getBytes())); right
getresult = xpathexpression.evaluate(isource);My xml string is like:
<a>
<b>
<result> valid some more tags here
</result>
</b>
<c> 10
</c>
</a>Edited by: geoman on Dec 8, 2008 2:30 PM

I've never used the version of evaluate that takes an InputSource. The difficulty with using it is that it does not save the DOM object. Each expression you evaluate will have to create the DOM object, use it once and then throw it away. I've yet to write a program that only needs one answer from an XML document. Usually, I use XPath to locate somewhere in a document and then read "nearby" content, add new content nearby, delete content, or move content. I'd suggest you may want to parse the XML stream and save the DOM Document.
Second, all of the XPath expressions search from a "context node". I have not had good luck searching from the Document object, so I always get the root element first. I think the expression should work if you use the root as the context node. You will need one of the versions of evaluate that uses an Object as the parameter.
