Xml parsing with Java
Hi ..!
I am having a small problem friends if anybody of you can just help me resolving this .
I am quiet new to working with parsing XML with SAX and Dom java parsers .
Problem is when we want to extract the Element name ,Attribute Name or Attribute Value it is quiet simple in Java to do so .
But supposing i want to extract the value between the tags of an element how can we do so either their is a simple method that i have missed or their is a tedious procedure that i am ignorant of.
eg- <Node1> this is my name <Node1>
Java source output -this is my name.
Thanx to you people for co-operating
Take care
Akshat
in SAX u can do like this
boolean nodeflag=false;
public void startElement(String uri,String localName, String qName,Attributes attributes)throws SAXException
if(qName.equals("Node1"))
nodeflag=true;
public void endElement (String uri, String localName, String qName)throws SAXException
if(qName.equals("Node1"))
nodeflag=false;
public void characters(char[] ch, int start,int length)throws SAXException
String s=new String(ch,start,length);
if(nodeflag==true)
if(!s.trim().equals(""))
System.out.println(s.trim());
}here in characters method u can work with data

XML Parsing with Java - Only some attributes have start and end tags
Hello,
I am trying to interpret the XML response from a server after a HTTP request is sent to it. I have modified an example off Wikipedia below to give an example of what it looks like.
Example XML:
<Asset name="bread" prep_time="5 mins" cook_time="3 hours">
<Attribute name="Ingredient: ">Flour</Attribute>
<Attribute name="Ingredient: ">Water</Attribute>
<Attribute name="Used in Recipes:" />
</recipe>
I have been trying to display the above XML in a format such as:
name: bread prep_time: 5 mins cook_time: 3 hours
Ingredient: Flour
Ingredient: Water
Used in Recipes:
Right now I have been trying to do it manually using indexOf and substring of the XML text, but I would like to find a better way of doing this. I have found some examples online that show had to deal with cases such as
<person>
<first>Kiran</first>
<last>Pai</last>
<age>22</age>
</person>
but I do not know what to do when I encounter something like the last item, when there are no "Used in Recipe" items, and it ends with a />, instead of an ending tag </Attribute>.
Are there any suggestions as to how to handle the example XML code that I have posted?
Any help would be appreciated. Thanks.jtahlborn wrote:

It is open to interpretation.

As long as one is mindful of the potential performance and maintenance impacts of course.Again, it depends what he's doing...true. I was making some assumptions, since (as usual) we don't really know the requirements beyond a base technical one (ie "I have this, and I need it to look like this"). In general, though, if you have XML data and you need it formatted differently then I'd say your first port of call ought to be transformation.
As for maintenance, I'd say it's easier to maintain a stylesheet than to modify Java, which is why I say it ought to be the start point.
Of course, YMMV. -
Upgrading Oracle XML Parser for Java v9.0.4 with Oracle Applications 11i
Guys, I applied ATG.PF.H.RUP4. In postinstall steps it is mentioned,Upgrading Oracle XML Parser for Java v9.0.4 with Oracle Applications 11i(doc-271148.1)
which says after applying patch 4038964 do the following--
AUTOCONFIG ENABLED APPLICATIONS ENVIRONMENT
If the Oracle E-Business Suite configuration files are maintained using the AutoConfig infrastructure, proceed with the following:
1. Run the AutoConfig utility.
2. Go to [JAVA_TOP].
3. Run the unzip -l appsborg2.zip | grep 9.0.4 command. If there is a file named as .xdkjava_version_9.0.4.0.0_production, which indicates that XML Parser for Java v9.0.4 is installed correctly as part of appsborg2.zip. Otherwise, run ADAdmin to regenerate the appsborg2.zip file.
4. Restart the application tier server processes such that the new version of Oracle XML Parser for Java will take effect.
but actually the patch is already applied- 4038964. How do i verify if i need to do these steps or not.
The xmlparserv2-904.zip file is already there in wrapper.classpath. of jserv.properties, forms.properties. So i think i dont need to do these steps.unzip -l appsborg2.zip | grep 9.0.4
0 04-18-03 20:10 .xdkjava_version_9.0.4.0.0_production
do i still need to do that step?No, you do not have to since "XML Parser for Java v9.0.4" is already installed as part of appsborg2.zip -
Can't use UTF-16 encoding with XML Parser for Java v2.
This is my XML Document:
<?xml version="1.0" encoding="UTF-16" ?>
<Content>
<Title>Documento de Prueba de gestin de contenidos.</Title>
<Creator>Roberto P rez Lita</Creator>
</Content>
This is the way in which i parse de document:
DOMParser parser=new DOMParser();
parser.setPreserveWhitespace(true);
parser.setErrorStream(System.err);
parser.setValidationMode(false);
parser.showWarnings(true);
parser.parse(
new FileInputStream(new File("PruebaA3Ingles.xml")));
I've got this error:
XML-0231 : (Error) Encoding 'UTF-16' is not currently supported.
I am using the XML Parser for Java v2_0_2_5 and I am a little
confused because the documentation says that the UTF-16 encoding
is supported in this version of the Parser.
Does anybody know how can I parse documents containing spanish
accents?
Thanks in advance.
Roberto P rez.
nullOracle just uploaded a new release of V2 Parser. It should
support UTF-16.
Yet, other utilities still have some problems with UTF-16
encoding. Seems we just
have to wait this one out.
BTW, I'm trying to use Japanese. We, also, have some problems
with JServer.

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??

Does the latest release of the Oracle XML Parser for Java support JDK 1.2.2?
I have an application which makes use of the XML Parser which runs fine with JDK 1.1.7.
But the application crashes with the use of JDK 1.2.2 .
Any insight into this is appreciated.
nullThe Oracle XSQL Servlet makes extensive use of the Oracle XML Parser for Java V2 as well as its XSLT Engine and runs without issue under 1.1.8 and 1.2.2.

I download the XML Parser for Java 3.2.1 Release from the IBM site and I have JDK1.3 installed on my Windows 2000 PC. I've placed the files "xerces.jar" and "xalan.jar" in the location specified by the extensions mechanism (i.e "C:\JDK1.3\jre\lib\ext\").
I downloaded an example where java uses XML but I get an error because it fails to import the following class:
import com.ibm.xml.parser.Parser;
Also in another application the same thing happens with this class:
import com.ibm.xml.parser.TXDocument;
If I remove the xerces and xalan JAR files from the directory mentioned above I get move errors so I presume I have the files in the right location. Do I need to place any other files in that DIR other than the xerces and xalan JAR files?
Any help greatly appreciated!Not sure if you solved your problem.
I think Xerces was handed over to the Apache organisation by IBM and the package names were then changed so that com.ibm would have become org.apache or whatever. At a guess nobody got round to changing the examples. -
Installing XML Parser for Java v2
I downloaded Oracle XML Parser for Java v2 and looked in the doc directory of the unzipped files but couldn't find any doc about installation. Can anyone point me in the right the direction or tell me how to install and use it to convert XML files stored in the files system to HTML output using XSL stylesheet. Thanks
There is no installation involved beyond including the xmlparserv2.jar in your CLASSPATH. Take a look in the sample directory where we have included sample code and instructions on their use.
Addiaitonal HTML conversion samples are included with the XSQL Servlet download.

ANN: Oracle XML Parser for Java v2.0.2
The new version of the Oracle XML Parser for Java v2 is
available for download and has the following features and
changes:
1. Conformance to the XSLT/XPATH August WD.
Note that there are several changes between April99 XSLT draft
and the August99 XSLT/Xpath draft and these changes have been
implemented in the XSL Processor. The XSL Processor has been
modified to accept XPath syntax for expressions and patterns.
Stylesheets might have to be modified to be conformant to the
August XSLT/XPath draft before they can be used with this
release.
Some of the changes between April draft and the August draft
are:
a. Expressions in the stylesheet must match the XPath
production Expr.
b. Some of the attribute names and element names in XSL
namespace have changed.
c. Some new functions have been added to XPath CORE function
library.
Please refer to the August XSLT/XPath draft for more details.
This is the first production release for v2.

What Oracle version for XML Parser for java
Is the XML Parser for Java only available for use with
Oracle 8i? Is it possible to use with Oracle 8.05
nullThe XML Parser for Java can be used with any of the supported
version JavaVMs. The only difference with 8i is that you can
load it into the database and use JServer which is an internal
VM. For 8.0.5 you simple run it externally and connect through
JDBC.

JAXP support in XML Parser for Java
Was curious if there were any plans to support JAXP in the XML Parser for Java. Sun's licensing terms was a serious issue of contention when Apache was trying to implement the spec and finally got an exemption from Sun to some of the terms.
The value of JAXP is that it allows one to
freely switch parsers without changing any code. I have an application that uses the JAXP interfaces to create my DOM parser. I am using the Xerces-J parser now. I wanted to try Oracle's parser to see how it compares. To my great surprise, I found the Oracle DOM parser doesn't support JAXP. Because of this I have to CHANGE my code to user the Oracle DOM parser. Thus defeating the purpose of coding my app to the JAXP interface.
I have to add that I am surprised to see that a developer of Oracle's XML parser has to even ask what the value of JAXP is. I would think that being a parser developer, you would know and understand the value of JAXP.
I would like to know why Oracle has chosen not to support JAXP? Or have you just not even thought about whether or not you should support it.
Thanks,
Keith Jensen
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Steven Muench ([email protected]):
What is the perceived value in implementing the JAXP standard? We already implement SAX, have plans for SAX2, and are working with other XSLT vendors on the TRAX api for XSLT processors.
If there is strong customer demand, we'll clearly consider it, but at the moment that has not been the case.<HR></BLOCKQUOTE>

Can I install XML parser for Java in Windows 98?
Could someone tell me how to install XML parser for Java in my PC Windows98 (I already installed JDK1.3)? Or it can not be installed in Windows98?
Thanks in advance!There's no reason why it shouldn't work on any platform for which JDK1.3 is available. If you're using the batch files shipped with XDK to run the parser, you might need to change the syntax slightly; in any event the key command is just
