Java - DOM Parsing - Reg

I am trying to get the value of the element - <e> -from an xml file which looks as below
<a>
<b>
<c> </c>
<d>
<e>SampleValue</e>
</d>
</b>
</a>
and I am using the Sun DOM1 parser. I am not sure what I missing I have tried using something like below
NodeList list = document.getElementByeTagName("b");
Node node = list.item(0);
NodeList list2 = node.getChildNodes();
for(i=0;i<list2.getLength();i++){
Node tempN = (Node)list2.item(i)
//I trying to get value of element "e"
System.out.print(tempN.getNodeValue());
I think I am missing something,could anyone ..help me out.
Thanks

String eValue=document.getElementsByTagName("e").item(0).getFirstChild().getNodeValue();

Java DOM Parser (XML)

Could someone please give me a link where I can find a example of a DOM parser, w3c. That shows how to parse an xml string or file and build the tree then access parts of it? I cant find a basic example anywhere!

Check this

Context change by DOM parsing Java Mapping in XI

Hi Team,
I would like to know that how can I handle Context Change by DOM Parser Java Mapping in XI.?
Suppose the source XML structure I have like below:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Header xmlns:ns0="urn:bp:xi:hr:edm:test:100">
   <FileName>
      <filesub>
         <subname>a</subname>
         <subname>b</subname>
         <subname>c</subname>
      </filesub>
   </FileName>
   <FileName>
      <filesub>
         <subname>d</subname>
         <subname>e</subname>
         <subname>f</subname>
      </filesub>
   </FileName>
</ns0:Header>
Where the field FileName can occur maximum thrice(0...3) but the subname field is (0....unbounded) but in the target source I would like to have as given below:
<?xml version="1.0" encoding="UTF-8" ?>
- <MT_Test4 xmlns="urn:bp:xi:hr:edm:test:100">
- <Header>
<FileName>a</FileName>
<FileName1>d</FileName1>
    </Header>
- <Header>
<FileName>b</FileName>
<FileName1>e</FileName1>
   </Header>
Header>
<FileName>c</FileName>
<FileName1>f</FileName1>
   </Header>
</MT_Test4>
That means the first value from every context of the source field is forming my first and second value in my target first context.Thensecond value from every context is forming my 1st and 2nd value of my target 2nd context and finally 3rd value of every context is forming my 1st and 2nd value of my target 3rd context.Is this possible to done through DOM parsing or we have to do it by UDF only?

Hope this helps
one more thing in this line "textChild=docOut.createTextNode(s k + j );"   somehow the the third braces one opening before k and one closing after j is missing for unknown reasons. Please correct it when you actually run this code.

Parsing an XML using DOM parser in Java in Recursive fashion

I need to parse an XML using DOM parser in Java. New tags can be added to the XML in future. Code should be written in such a way that even with new tags added there should not be any code change. I felt that parsing the XML recursively can solve this problem. Can any one please share sample Java code that parses XML recursively. Thanks in Advance.

Actually, if you are planning to use DOM then you will be doing that task after you parse the data. But anyway, have you read any tutorials or books about how to process XML in Java? If not, my suggestion would be to start by doing that. You cannot learn that by fishing on forums. Try this one for example:

Parsing xml using DOM parser in java

hi there!!!
i don have much idea about parsing xml.. i have an xml file which consists of details regarding indentation and spacing standards of C lang.. i need to read the file using DOM parser in java n store each of the attributes n elements in some data structure in java..
need help as soon as possible!!!

DOM is the easiest way to parse XML document, google for JDOM example it is very easy to implement.
you need to know what is attribute, what is text content and what is Value in XML then easily you can parse your document with dom (watch for space[text#] in your XML document when you parse it).
you get root node then nodelist of childs for root then go further inside, it is easy believe me.

See if the Text 'oldText' actually has any text within it. Sometimes in DOM parsing, you will get something like:
Element
   Text (blank)
   Text (actual)
   Text (blank)Whereas you would expect to receive:
Element
   Text (actual)See if that is the case. If yes, modify your logic to iterate through the child text nodes until one with actual text inside of it (getNodeValue()) is found.

How to manipulate object mapping runtime using DOM parser in java?

Scenario: We will be getting logical name of the table from which we have to fetch the details. We have few tables which have more or less same columns, the only difference is the prefix. Say we have Tables: Temp1 and Temp2 contains column as Temp1Col1 and Temp2Col1. I dont want to go with creating as many POJO classes in java as that of tables. So i will create only one POJO class with common attributes and at runtime i want to change the object mapping file of Hibernate to hold table values. I have an idea that this can be done using DOM parser. But it would be great if somebody can share the java code for the same.
Thanks in advance.

SAX is a parser, not a generator.Well,
you can use it to create an XML file too. And it will take care of proper encoding, thus being much superior to a normal textwriter:
See the following code snippet (out is a OutputStream):
PrintWriter pw = new PrintWriter(out);
      StreamResult streamResult = new StreamResult(pw);
      SAXTransformerFactory tf = (SAXTransformerFactory) TransformerFactory.newInstance();
      //      SAX2.0 ContentHandler.
      TransformerHandler hd = tf.newTransformerHandler();
      Transformer serializer = hd.getTransformer();
      serializer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");//
      serializer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"pdfBookmarks.xsd");
      serializer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"http://schema.inplus.de/pdf/1.0");
      serializer.setOutputProperty(OutputKeys.METHOD,"xml");
      serializer.setOutputProperty(OutputKeys.INDENT, "yes");
      hd.setResult(streamResult);
      hd.startDocument();
      //Get a processing instruction
      hd.processingInstruction("xml-stylesheet","type=\"text/xsl\" href=\"mystyle.xsl\"");
      AttributesImpl atts = new AttributesImpl();
      atts.addAttribute("", "", "someattribute", "CDATA", "test");
      atts.addAttribute("", "", "moreattributes", "CDATA", "test2");
       hd.startElement("", "", "MyTag", atts);
String curTitle = "Something inside a tag";
          hd.characters(curTitle.toCharArray(), 0, curTitle.length());
    hd.endElement("", "", "MyTag");
      hd.endDocument();
You are responsible for proper nesting. SAX takes care of encoding.

You have probably found lots of resources on the www for this by now, if not: [http://www.w3schools.com/dom/default.asp|http://www.w3schools.com/dom/default.asp]

I know signing the applet a bit. But though it is signed , second exception is constantly thrown. so please write in detail the procedure to sign the applet. and how to download xalan.jar in html page etc.,
I require how to download the jar files, and after the completion of downloading of the jar files only, the applet should get executed. or shall i use different jar file(like crimson.jar?). This is urgent requirement.Please help me.!
the classes for the parsing are not at all downloaded and hence the problem.
help me reg that.
thank you in advance/.
Prasanna kumar k.

Hello Prasanna kumar k.
First you should sign your jar files (xerces.jar crimson.jar and xalan.jar) and recreate a cab files
xerces.cab crimson.cab xalan.cab. To do that you should download sdk for java from microsoft .
create testkey named testkey.pvk
1. makecert -sv testkey.pvk -n "CN=your name" test.cer
convert to public key
2. cert2spc test.cer test.spc :
create cab file
3. cabarc -p -c -r -s 6144 test.cab
sign the cab file
4. signcode -j java.dll -jp -low -spc -v testkey.pvk -n test.cab
after that you should use thia files in html:
<!doctype html public "//W3//DID HTML 3.2 Final//EN">
<HTML>

I have signed the Applet using signcode utility and i have put the
parserapplet.class in the MyApplet cab file and signed it. On invoking
the html file, it request for permission, and after clicking yes, the
applet loads.Fine.
No problem upto this stage.
But after loading of the applet the following exception is thrown in
Javaconsole.

I dont know which .jar file to archive (i tried xalan,crimson, jaxp
but which of no use). I was surprised why the security Exception is
thrown , when parsing.
I have not accessed the System files!( but it searches for
jaxp.properties file!). I think the jar file is not downloaded. How to
verify that it is downloaded in applet?
The above code is only for sample.
If anybody who knows how to correct it please mail me at:
"[email protected]" with corrected code. I want this very
urgently.
Help meeeeeeeeeeeeeeeeeeee!!!!!
Prasanna.

Have you found the answer to this problem? I am having a similar problem when running the parser in an ActiveX Bean.
THanks

Problem in parsing a xml string using dom parser

i want to parse a Xml String using a Dom parser......the parse function in dom parser takes only input stream as argument.......so i made the code as
InputStream inputstream = new StringBufferInputStream(XmlData) ;
InputSource inputSource = new InputSource(inputstream );
but saxexception is coming and also warning called
"java.io.StringBufferInputStream in java.io has been deprecated"
please help me.........

i want to parse a Xml String using a Dom
parser......the parse function in dom parser takes
only input stream as argument.......This is not true of the DOM parser in Java 1.4. So you might want to get rid of your old parser and replace it by something more current. Or perhaps you are using 1.4 and you just didn't read all of the API docs.

can any body tell me how to validate the repeating tags (as i dont have dtd for this xml )with the given code.... if any one of the tags are repeating it should raise an exception thats its not a valid xml
Thanks in advance
Regards
Bunny

I suggest you create a DTD or a XSD file to validate your existing XML document, because it's easier that i looks, and will help in future changes.
If you want to do it in Java code, you can always store each line of the XML file in some form (like a class) in a List, and the each time you read a line, you compare with everything on the list.
But don't go that way, make a XSD file

     testxml txml=new testxml(); txml.processXML("E:\\Naresh\\conversion_fxsql.xml");
can any body tell me how to validate the repeating tags with the given code.... if any one of the tags are repeating it should raise an exception thats its not a valid xml
Thanks in advance

The first problem about this document is that it contains a space at the very first position whereas <?xml... must appear at the very beginning of a document. I think this was the cause of the parsing fault.
Also you have a dash before the root element of the document, which is illegal.

JmsAdapter DOM Parsing Exception handling

Hi,
I'm currently facing a problem with the behaviour of the Jms Adapter.
Whenever a JMS message is put in the queue and that message is not XML valid, the Jms Adapter (consumer) throw the exception "DOM Parsing Exception in translator Exception".
That's fine, I understand that the message was not well formed. But what is not fine is that the underlying BPEL is not instanciated : meaning I can't handle the exception properly.
Is there a way to force the Jms Adapter not to crash on the DOM Parsing for the BPEL to be instanciated (and then being able to handle the exception there) ?
Or is there a way to handle the error thrown by the Jms Adapter itself ? How ?
I think I do have a workaround to this if there is no better option (if both above questions cannot be answered) but I would rather not implement it since it will involve some extra steps / complexity.
> It would be to check the "native format opaque schema" option and then use a java embedded to decode the base64 into a string for eventually parsing it.

Hi Mathieu,
The messages that error out before being posted to the service infrastructure are referred to as rejected messages. For example, the Oracle File Adapter selects a file having data in CSV format and tries to translate it to XML format (using NXSD). If there is any error in the translation, this message is rejected and are not be posted to the target composite.
You can create rejection handlers to handle message errors. Message errors include those that occur during translation, correlation ID mismatch and XML parsing after message reception.
Docs on how to do that are here...
