Problem writing xml file using DOM

Hi,
I am trying to write a xml file using DOM. I am using xalan 2.5, xerces 1.4.4, jdk 1.3.1 in JRun 3 on windows.
The code where I get exception :
               TransformerFactory tFactory = TransformerFactory.newInstance();
               Transformer transformer = tFactory.newTransformer();
               transformer.transform(new DOMSource(doc), new StreamResult("pr.xml"));
I get the runtime error as follows:
javax.servlet.ServletException: null
java.lang.NoSuchMethodError
     at org.apache.xml.utils.DOM2Helper.getNamespaceOfNodeDOM2Helper.java:342)
     at org.apache.xml.utils.TreeWalker.startNode(TreeWalker.java:387)
     at org.apache.xml.utils.TreeWalker.traverse(TreeWalker.java:202)
     at org.apache.xalan.transformer.TransformerIdentityImpl.transform(TransformerIdentityImpl.java:343)
Thinking it is because of classpath, I placed xalan 2.5, xerces 1.4.4 jar files in jrun admin lib directory and in server lib directory as well. Still getting the same error.
Any suggestion?
Thanks in advance

xalan is included in JRun 4. However JRun 3 does not.
However I tried with the same code in JRun3 in different system. The error is completely different. I understand this is because of different version of files. trying to solve ;)
Here my new exception

"encoding = UTF-8" missing while writing XML file using file Adapter

Hi,
We are facing an unique problem writing xml file using file adapter. The file is coming without the encoding part in the header of xml. An excerpt of the file that is getting generated:
<?xml version="1.0" ?>
<customerSet>
<user>
<externalID>51017</externalID>
<userInfo>
<employeeID>51017</employeeID>
<employeeType>Contractor</employeeType>

<companyName>HQ-Milpitas, US</companyName>
<workphone>

</workphone>
<mobilePhone>

So if you see the header the "encoding=UTF-8" is missing after "version-1.0".
Do we need to configure any properties in File Adapter?? Or is it the standard way of rendering by the adapter.
Please advice.
Thanks in advance!!!

Updating XML file using DOM parser

Hi,
Can someone help me, how to update following XML file using DOM parser.
The following is my XML file.
<students>
     <student>
          <id>1</id>
          <name>abc</name>
     </student>
     <student>
          <id>2</id>
          <name>xyz</name>
     </student>
     <student>
          <id>3</id>
          <name/>
     </student>
     <student>
          <id>4</id>
          <name>ijk</name>
     </student>
     <student>
          <id>5</id>
          <name></name>
     </student>
</students>Consider, I will input 2 fields, ie., id & name. For the matching Id, the name has to be updated.
Though, I have achieved this, but I am unable to update the value for 3rd record, & 5th record ie., id=3 & id=5. Since, these are blank.
Thanks.

Some <name> elements have a child node which is a text node. From what you say it appears you know how to change those text nodes.
The other <name> elements don't have any child nodes. But you want one. This suggests to me that you need code that creates a text node and adds it to the <name> element as its child.

Problem loading XML-file using SQL*Loader

Hello,
I'm using 9.2 and tryin to load a XML-file using SQL*Loader.
Loader control-file:
LOAD DATA
INFILE *
INTO TABLE BATCH_TABLE TRUNCATE
FIELDS TERMINATED BY ','
FILENAME char(255),
XML_DATA LOBFILE (FILENAME) TERMINATED BY EOF
BEGINDATA
data.xml
The BATCH_TABLE is created as:
CREATE TABLE BATCH_TABLE (
FILENAME VARCHAR2 (50),
XML_DATA SYS.XMLTYPE ) ;
And the data.xml contains the following lines:
<?xml version="2.0" encoding="UTF-8"?>
<!DOCTYPE databatch SYSTEM "databatch.dtd">
<batch>
<record>
<data>
<type>10</type>
</data>
</record>
<record>
<data>
<type>20</type>
</data>
</record>
</batch>
However, the sqlldr gives me an error:
Record 1: Rejected - Error on table BATCH_TABLE, column XML_DATA.
ORA-21700: object does not exist or is marked for delete
ORA-06512: at "SYS.XMLTYPE", line 0
ORA-06512: at line 1
If I remove the first two lines
"<?xml version="2.0" encoding="UTF-8"?>"
and
"<!DOCTYPE databatch SYSTEM "databatch.dtd">"
from data.xml everything works, and the contentents of data.xml are loaded into the table.
Any idea what I'm missing here? Likely the problem is with special characters.
Thanks in advance,

I'm able to load your file just by removing the second line <!DOCTYPE databatch SYSTEM "databatch.dtd">. I dont have your dtd file, so skipped that line. Can you check if it's problem with ur DTD?

Problem while parsing xml file using DOM

I have a xml file NewXML.xml. When I parse it I'm not getting the expected output: I'm trying to get only the value of the "name" tag. When I tried getElementByTagName("name"), I'm not getting the expected result.
Here is my xml file based on a schema
<?xml version="1.0" encoding="UTF-8"?>
<student xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="NewXMLSchema.xsd">
<name>john</name>
<id>1000</id>
</student>
Coding:
public static void main(String argv[])
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
Document document ;
try {
DocumentBuilder builder = factory.newDocumentBuilder();
document = builder.parse( "NewXML.xml" );
NodeList nodeList = (document.getElementsByTagName("name") );
System.out.println(nodeList.getLength()+" node list "+nodeList.item(0));
System.out.println(nodeList.item(0).getNodeValue());
NodeList nodeList1 = nodeList.item(0).getChildNodes();
System.out.println(nodeList1.getLength()+" node list "+nodeList1.item(0));
System.out.println(nodeList1.item(0).getNodeValue());
When I ran the above coding I got:
1 node list [name: null]
null
1 node list [#text: name]
name
What should I do to get the result "john" inorder to change it
Thanks

Writing to a xml file using DOM API

Hi,
I try to write some elements in an existing xml file.
Document doc = null;
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
try
     builder = factory.newDocumentBuilder();
     doc = builder.parse("c:/WUTEMP/rules.xml");
     Element rules = doc.getDocumentElement();
     Element eRule = doc.createElement("rule");
     rules.appendChild(eRule);
     Element ruleSyntax = doc.createElement("rule-syntax");
     eRule.appendChild(ruleSyntax);
     ruleSyntax.appendChild(doc.createTextNode(syntax));
It runs without errors but the xml file isn't changed. Some ideas ?
Structure of xml file:
<rules>
</rules>
And executing code above must resulting in :
<rules>
<rule-syntax> </rule-syntax>
</rules>
But nothing happens with the file.

Code below did the trick:
Transformer xformer = TransformerFactory.newInstance().newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File("c:/WUTEMP/rules.xml"));
xformer.transform(source, result);

Store and load objects to XML files using DOM

Hello everybody,
a quick question for all of you.
I'm designing a desktop application which requires a lot of custom objects to be stored into XML files and later reloaded from them. I'm planning to use DOM, creating an interface like this:
public interface StorableAsDom
// Create an object from a DOM tree
static Object createFromDom(org.w3c.dom.Node root) throws InvalidDomException;
// Get the DOM tree for an object
org.w3c.dom.DocumentFragment getDomTree(org.w3c.dom.Document doc) throws DOMException;
Then, every class which needs to be saved should implement the above interface. This way everything works fine.
My question is: do you know any available java package which already provides similar functionalities?
I'd like not to reinvent the wheel if I can; time is always a critical factor.
Thanks in advance to all of you.
Cheers

Hi,
When I need object -xml binding, I usually have two methods -
one for reading & one for writing (the "VOs" below stands for "Value Objects" [getters/setters & empty constructor only]):
READ: loadXML (= XML2VOs)
1.XML2DOM - this method can be generic
2.DOM2VOs - populate your VOs from the DOM just obtained in 1.
WRITE: saveXML (=VOs2XML)
1.VOs2DOM - create a new DOM document from your VOs' fields.
2.DOM2XML - this method can be generic
It would be nice (but dificult & not very elegant) to make DOM2VOs & VOs2DOM generic. If such methods will be written, they should be combined with the XML2DOM & DOM2XML (resp.) & then you would have two generic methods XML2VOs & VOs2XML... (Alternativelly, you can get Sun's JAXB package which does object-xml binding but this is not part of the JDK 5)
If what I have outlined above sounds like what you want to do, let me know if you want more details (eg. how the DOM2VOs would be implemented etc)...

because what you want is not the node value of CODE but the node value of the text nodes into it!

How to remove element namespaces in XML file using DOM or SAX?

Hi Guys,
I developed a JAVA mapping in XI to add name spaces for XML file, after mapping,name spaces xmlns="http://www.mro.com/mx/integration" and xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" were added correctly, but for some nodes, such as <Header> and <Content>, a name space xmlns="" was added automatically.Please check below files to compare.
It looks like be added automatically by XI. I didn't process anything for these nodes in JAVA program.
Now the issue is, how can I remove these redundant namespaces? Such as xmlns="".
Can I remove them using DOM or SAX in JAVA Mapping?
Thanks in advance.

Hi Milan,
Thanks for your replay.
Actually when I used module XMLAnonymizerBean to convert namespaces, the header of XML, such as <?xml version="1.0" encoding="UTF-8"?> was converted to format <?xml version='1.0' encoding='UTF-8'?>, quote was converted to single quote. Although I set parameter anonymizer.quote = ", it still didn't work, single quote appeared instead of quote.
I'm not sure why this happened. Can anyone help to clarify this?
Thanks

Writing XML file using javax.xml package

I am writing an XML file with the foll piece of code:
public static void writeXmlFile(Document doc, String filename) {
try {
// Prepare the DOM document for writing
Source source = new DOMSource(doc);
// Prepare the output file
File file = new File(filename);
Result result = new StreamResult(file);
// Write the DOM document to the file
Transformer xformer = TransformerFactory.newInstance().newTransformer();
xformer.transform(source, result);
} catch (TransformerConfigurationException e) {
} catch (TransformerException e) {
In this case above, the whole Document has to be passed to create a new DOMSource. is there any way where in I can pass the individual Nodes to the DOMSource ?
I want the Nodes to be written one by one as writing the whole document is giving me a OutOfMemoryError (I have about a million records to be written in the XML file).
Any help would be greatly appreciated

Writing XML files using file adapter

Hi All,
I am using Oracle file adapter to write xml files, I am poinitng it to an xsd while specifying schema.The XML files are getting generated with target namespace information and name space prefixes in the xml data elements. I have a specific requirement to create xml files without any namespace/name space prefix tags in it. Can we acheive it using file adapter?
otherwise is there anyother way of doing this in bpel.
Any suggestions are welcome.

What is the name you have entered in sender channel, if you have entered.pdf only it process PDF files. select option skip empty file option in sender channel and enter name ..
most probably this issue coming with empty files.

How to parse nested xml file using dom

i want to parse nested xml file
please tell me how to parse nested xml
for eg.
<xml>
<row>
<name>Rahul<name>
<row><newXml>
<newXML>
<Row>
<code>12</code>
</Row>
<newXML>
<XML>
please tell how to parse this file

Normally if you have no idea about X, the first thing you should do is google "X tutorial". You will find plenty of them out there. And the advantage is, they are better written than whatever we spend two minutes throwing together here. Not to mention that it saves us the two minutes.
But if you have specific questions with your SAX parser when you get it going, then ask them here. Actually, ask them in the XML forum here, not this one.

I just want to parse this file and want to store the values in desired datastructures,
I am trying using DOM parser, since it gives a tree structure, which is ok in this case.
public void init()
          InputReader ir     =new InputReader("Habsys");
          Document      doc     =ir.read("Habitat");
          System.out.println(doc);
          traverse(doc);
private void traverse(Document idoc)
          NodeList lchildren=idoc.getElementsByTagName("SubItem");
          for(int i=0;i<lchildren.getLength();i++)
               String lgstr=lchildren.item(i).getNodeName();
               if(lgstr.equals("SubItem"))
                    traverse(lchildren.item(i));
private void traverse (Node node) {
int type = node.getNodeType();
if (type == Node.ELEMENT_NODE)
System.out.println ("Name :"+node.getNodeName());
if(!node.hasChildNodes())
System.out.println ("Value :"+node.getNodeValue());
NodeList children = node.getChildNodes();
if (children != null) {
for (int i=0; i< children.getLength(); i++)
traverse (children.item(i));
But I am not getting required results, a lot of values I am getting as null
Could anybody tell me how to retrieve the data from the xml file, I simply want to read data and store it in data structures. For eg, for tag Subitem with title as ' SubItem1' has attr1 as '1', attr2 as'0' and attr3 as '0'.
Thanks

Creating XML File Using xmldom Package

How can I create an XML file from scratch using the PL/SQL xmldom package?
I want to create an XML file using the xmldom package instead of building the individual tags as strings of VARCHAR2 character data. There is quite a bit of documentation regarding manipulating input XML files using DOM -- but not for creating XML files from scratch given known "tagnames" (<lastName>) and retrieved database "values" ("Smith").
<person>
<lastName>Smith</lastName>
</person>
Is there any documentation that you can recommend?
Thank you.

Here is an example.
The create_file procedure creates the file.
The other procedures are generic procs that can be used with any XML.
