Using a xml parser with jbuilder

I'm using jbuilder and the required librairies I've just added require me to add an XML parser to the path. I've just downloaded one from www.apache.org.
How do I incorporate this parser into my project. I need to use the following packages but I'm not sure how I can put everything together.
If you understand what my problem is please help. Thanks , B.
import org.w3c.dom.Document;
import org.w3c.dom.DOMException;

Go to tools | configure libraries.
click the new button on the left
Type in the name you want the library to be identified with (XML Parser or something)
Choose the location (this determines how many people and projects have access to the libraries)
Click the add button and find the *.jar files.
Ok back out of the dialogs
Now select the Project Properties (or default props to have the library available to all projects, not recommended tho)
Select the paths tab
Click Add and select the Library you added in the earlier steps.
If you have any probs, www.borland.com has heaps of stuff on configuring libraries

HOW TO: Use the XML parser in Oracle 8.1.7

I am trying to figure out how to use the xml parser provided in oracle 8.1.7. all i want to do is parse a xml report that is defined using a schema, and place the data into the proper tables. i am totally unfamiliar with the xml parser and how it works. i have done some reading on the subject, but seem to be getting some conflicting infromation about which utilites i need and how to invoke them. can someone please tell me what utilities i need, how to invoke them, and what i need to do to get a xml document to parse and insert to a table? I would greatly appreciate any help anybody could offer. thanks.

You can parse the XML Document with XML Parser and place the data into database using XSU(XML SQL Utility).
Both of these are included in XDK for Java at:

Problem for using oracle xml parser v2 for 8.1.7

My first posting was messed up. This is re-posting the same question.
Problem for using oracle xml parser v2 for 8.1.7
I have a sylesheet with
<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl">.
It works fine if I refer this xsl file in xml file as follows:
<?xml-stylesheet type="text/xsl" href="http://...../GN.xsl"?>.
When I use this xsl in pl/sql package, I got
ORA-20100: Error occurred while processing: XSL-1009: Attribute 'xsl:version' not found in 'xsl:stylesheet'.
After I changed name space definition to
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> in xsl file, I got
ORA-20100: Error occurred while processing: XSL-1019: Expected ']' instead of '$'.
I am using xml parser v2 for 8.1.7
Can anyone explain why it happens? What is the solution?

Steve,
We are also creating an XML DOM from java and are having trouble getting the tags created as we want. When we use XMLText it creates the tag as <tagName/>value rather than <tagName>value</tagName>. We want separate open and close tags. Any ideas?

XML validation using Oracle XML parser v2

Not sure if this is the right forum for this question as I didn't found any.
I had a tough time trying to build an XMLSchema (Oracle XML Parser V2) object from the input schema having include/import. Actually I am working on a Java program to validate the input xml with input schema using Oracle XML parser v2 api.
The issue is that the code doesn't work for schema that has some "include" in it. The code is working fine for the schema without any import/include. Here is the lines of code -
XSDBuilder builder = new XSDBuilder();
schema = builder.build(new InputSource(xsdReader));
I am writing this in JDeveloper. The error is -
oracle.xml.parser.schema.XSDException: Can not build schema 'http://www.fpml.org/2005/FpML-4-2' located at 'xsd\FpML42\xml\fpml-fx-4-2.xsd'
I also tried creating the EntityResolver to specify the path of included schema. But that doesn't solves the problem.
I am not sure whether parser is able to locate the included schema or not.The main schema and included schema are all in same folder. The included schema is perfectly fine and has no errors.
Please help if you have encountered this issue and resolved it. I will really appreciate any pointers or clue to solve this issue.
Thanks.

Thanks for the reply. But it does not seem to be working. Am I missing something
I put <TrxDate xsi:nil="true"/> but still getting error.
Here's my xsd:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
<xsd:element name="TrxDate" type="xsd:date" nillable="true" />
XML:
<?xml version="1.0" encoding="UTF-8" ?>

<TrxDate nil="true"/>

Parsing errors with CDATA tags using oracle xml parser v2

I'm using the oracle.xml.parser.v2 parser to combine a
generated xml document from a database with a static
xsl file to produce html. Within the xml document, there
are fairly large CDATA sections (500 lines) which happen
to contain javaScript.
Occasionally, I'm getting xml tags in the final html
document! It seems that the oracle parser pukes
on a certain type of data within a CDATA tag, and then
replaces an angle bracket (<) of a tag with a #60. This
can cause html tags being viewed in the document. At
first, I thought the amount of JavaScript within the
CDATA tag was too large for the parser to handle,
because when I split it up into 2 or more parts the errors
went away. But, re-arranging the JavaScript (String in the CDATA tag)
can make the errors disappear. And, if I
use the Saxon parser to manually combine the xsl with
the xml, the output is fine. If anyone knows that this is
a confirmed bug by Oracle, or any other relevant info on
this, please let me know.

Hi,
Your lucky, i've just finished a project that used the oracle parser extensively.
I think the problem may stem from your xsl. Although your cdata tags may be well formed, in the xsl you might need to escape the text again, this may mean that the xsl needs to print a further cdata tag around the data. This is because the parser (well the version I was using) strips the cdata tags before the transformation happens.
This is the probably the cause of the nasty html output.

XML parser with document support

Hi all,
For a whole week now, I m still looking for a nice (but lite) XML parser for J2ME applications. Of course I found kXML 2 parser but I'm confused.
kXML 2 implements the XmlPull API (xmlpull.org) so you can parse easly an XML file with functions as next(), ...
BUT, I would like to deal with a Document Object Model (DOM) (like JDom for J2SE), with this I will be able to do some nice stuff like doc.getRoot().getElement....
In kXML2 Javadoc I found something like this but apparently it doesnt work well (or I dont know how to use it).
Do someone know this API ? http://kxml.sourceforge.net/kxml2/javadoc/
I can't find any example on Internet, everybody seems to use it without DOM....
Until someone give me an answer I will continue to use kXML2 without document object model :(
thanks guys,

just a search..in http://sourceforge.net/

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).

Can we use javax.xml.parser API's from j2sdk kit?

Hi All,
I am new to this jaxp API's and my first doubt is Can I use the javax.xml.parser API which come bundled with j2sdk-1.4.1 or Should I install JWSDP-1.3 to get to javax.xml.parsers API?
Thanks

Hi,
I am trying to read an xml file on Solaris.
Can we not use doc.getElementById(String elementID) after deriving doc obejct ?
Here is the code I am trying to use:
try
factory = DocumentBuilderFactory.newInstance();
factory.setValidating(false);
File file = new File("/command/parse_doc.xml");
doc = factory.newDocumentBuilder().parse(file); //upto here it works
Element element = doc.getElementById("Topics");
String name = element.getTagName(); //returns nothing but throws exception "null"
}catch(Exception exe){
out.println("Exception:" + exe.getMessage());}
here I get no such element, and the try catch block exception also null.
Is there something I am missing?
DO I have to call doc.getDocumentElement() before I call get ElementBy ID() and if so why?
Thanks.

How to use sax xml parser

hi was wondering if someone could give me an example on how to use sax
and a document handler and explain a bit

to use sax parsers you need basically to extends handlerBase wich will force you to have the 3 following methods
// imports for the sax portion of the manager,
// the portion that will permit the interpretation of
import com.sun.xml.parser.Resolver;
import org.xml.sax.*;
import org.xml.sax.helpers.ParserFactory;
public class XMLManager extends HandlerBase
private String currentElement = null; //current element name for parsing
* Default constructor
public XMLManager()
/*SAX METHODS*/
* This method is called when the SAX parser encounters an open element
* tag. Must remember which element tag was just opened (so that the
* characters(..) method can do something useful with the data that is
* read by the parser.
public void startElement(String name,AttributeList atts){
if( name.equalsIgnoreCase("MY XML TAG NAME") )
currentElement = "MY XML TAG NAME";
//then do stuff for that type of tag
* This method is called when the SAX parser encounters a close element
* tag. If the message tag is closed it means the message is valid and ready
* to be treated
public void endElement(String name){
currentElement = "";
* This method is called when the SAX parser encounters #PCDATA or CDATA.
* It is important to remember which element tag was just opened so that
* this data can be put in the right object or variable.
* Also the start index and length integer must be used to retrieve only
* a portion of the data stored in the char[]
* This section will only contain treatment for tags wich have content
* between start and end tags
public void characters(char ch[],int start,int length){
//dont read ch[] , use the
//range provided by the SAX parser.
String value = new String(ch,start ,length);
Once you have defined these 3 methods, define a method called for example parseIt(String mss) wich will contain the following code to parse the content of a string mss, a string containing xml data
try
//create an InputSource from the XML source received
StringReader r = new StringReader(mss);
InputSource is = new InputSource( r );
//create a SAX parser using SAX interfaces and classes
String parserClassName = "com.sun.xml.parser.Parser";
org.xml.sax.Parser parser = org.xml.sax.helpers.ParserFactory.makeParser(parserClassName);
//create document handler to do something useful
//with the XML document being parsed by the parser.
parser.setDocumentHandler(this);
parser.parse(is);
catch(Throwable t){System.out.println(t);t.printStackTrace();}
you can't fail with this ;)

XML parsing with SQL/PL-SQL

Hi,
My question is about how can an XML message can be best parsed using SQL/PL-SQL.
The scenario is as follow. The XML message is stored in a CLOB; only some of its data needs to be extracted; there are six different types of structures of XML; the size of each XML is about 50 lines (maximum depth level is 3); the data could be written in English or Greek or French or German or Russian; this is going to be done every hour and the parsing is going to be against 3,000 records approx.
In the development, I need to take into consideration performance. We are using Oracle 10, but we could migrate to Oracle 11 if necessary.
Apologies for this basic question but I have never done XML parsing in SQL/PL-SQL before.
Thank you.
PS I have copied this question to the XML forum.

XML parsing with DOM

I'm using xerces to parse an XML file and am running in to trouble. Do you have to parse child nodes before attributes? I do this in every node except for one called "table" in my parser. However, I have an abstract class called "Table" that is subclassed by Table1D and Table2D, and I need to parse the attributes to know which to instantiate.
The problem is, I have a child node called scale. For some reason, scale is being parsed as if it were a table.
Here is a look at my unmarshallTable method. Ignore the lack of exception handling.
private Table unmarshallTable(Node tableNode) {
     Table table;
        if (unmarshallAttribute(tableNode, "type", "unknown").equals("3D")) {
            table = new Table3D();
        } else if (unmarshallAttribute(tableNode, "type", "unknown").equals("2D")) {
        } else {
            //exception
            return null;
        table.setName(unmarshallAttribute(tableNode, "name", "unknown"));
        if (table.getType().equals("2D")) {
            ((Table2D)table).setFlipX(Boolean.parseBoolean(unmarshallAttribute(tableNode, "flipx", "unknown")));
     Node n;
     NodeList nodes = tableNode.getChildNodes();
     for (int i = 0; i < nodes.getLength(); i++) {
         n = nodes.item(i);
         if (n.getNodeType() == Node.ELEMENT_NODE) {
          if (tableNode.getNodeName().equals("table")) {
              if (table.getType().equals("2D")) {
                        if (unmarshallTable(n).getType().equals("Static Y Axis")) {
                            ((Table2D)table).setStaticYAxis((Table1D)unmarshallTable(n));
                    } else if (table.getType().equals("3D")) {
                        if (unmarshallTable(n).getType().equals("X Axis")) {
                            ((Table3D)table).setXAxis((Table1D)unmarshallTable(n));
                        } else if (unmarshallTable(n).getType().equals("Y Axis")) {
                            ((Table3D)table).setYAxis((Table1D)unmarshallTable(n));
                } else if (tableNode.getNodeName().equals("scaling")) {
                    table.setScale(unmarshallScale(n));
          } else {
              // unexpected element in Article
         } else {
          // unexpected node-type in Article
     return table;
    }

Doh! I got it.
if (tableNode.getNodeName().equals("table")) {
should be
if (n.getNodeName().equals("table")) {

Hi,

My aplication receives an absolute path but this
doesn't work:
StringReader oStringReader =
new StringReader(c:\java\libros.xml);
However it works with:
StringReader oStringReader =
new StringReader("<?xml version="1.0" e......");
ie, with the whole document as a String, but I need
to do it as the frist way.
Thankstake a look at this link:

Is it possible to configure CF10 or CF11 to use Xerces XML parser instead of Saxon XML parser?

Could anyone tell me if it is possible to configure CF10 or CF 11 to use the older Xerces XML parser instead of the Saxon XML parser.
I am in the process of migrating a website from CF8 to CF11. Several sections rely on XML transformation, which no longer work in CF11. After investigating the problem it seems to be that the Saxon Parser is more strict, causing these errors.

Well I guess Parsers would be better solution. As u said u need to insert node at specific location.
so now u have to decide which parser u need to choose according to u r requirmnet. DOM or SAX maily.
Both has adv and di-advs.

Use of XML parser to read/parse xml stored in DB as CLOB

Hello,
I am new to XML technology. I have xml data stored in DB as
CLOB. I need to parse this data to retrieve VALUE fro certain
tags. I would greatly appreciate any help. Any examples that
manipulate xml data stored in DB can be of extreme help.
DesiDBA

As you use Oracle 9.0.1. We suggest you use XMLType instead of
CLOB to store your XML documents.
You can use xmlType.extract() to get the elements within the
XMLDocuments.
Please refer to our Oracle9i XML Demo for examples.
http://otn.oracle.com/tech/xml/xdk_sample/xdkdemo_faq.html
For Instructions:
http://ws5.olab.oracle.com/faqdemo/source/instruction.xsql?
pagename=ins_xmltype
Or you have to do the SQL query to get XML documents and parse
each document and extract the content yourself using XML Parser
for PL/SQL.
Thanks.

Libs to link when using C XML parser

Can anyone explain why this work:
LIB =-lcore8 -lnls8 -lcore8 -lnls8 -lcore8
but not this:
LIB =-lcore8 -lnls8
It causes link errors.
They are the libraries distributed with the Oracle C XML parser.

Thank you for your answer! It is good to know how it works particularly because we have had a lot of problems with this parser.
