Null representation in xml
Hi All,
I have to represent a datatbase value 'null' in xml.
I use a thirdparty api(propreitary, not well know and which I have no control) for conversion and null is representaed in xml as �
Is this correct?
But while parsing the xml data i get illegel charcter exception for �
Also browser(IE, Mozilla) also shows illegal character for �
Please advise and tell me the correct representation for null in xml.
regards,
java_india
The nul character (unicode codepoint zero, enn u one-ell) is not legal in XML documents.
There are several means of representing a NULL value (a DB undefined value, enn u double-ell) in XML, including implicitly - the value is null if the element or attribute representing that value is not present, or explicitly using a application defined element, or the xsi:null attribute on an element has been used for this (though not strictly the same - see http://lists.w3.org/Archives/Public/www-xml-schema-comments/2001JanMar/0025.html ).
I'd go for an application specific attrbute for an update that is nulling an existing value, and omitting the value for query or creating a new value.

Converting Idoc flat file representation to XML
Hi ,
I went through the guide for How To Convert Between IDoc and XML in XI 3.0. I'm concerned with the second part of the guide which says convert from falt file representation of Idoc to XML. Can anyone tell me what are the other design and configuration objects to be created for this scenario ( message types,interfaces, mapping , etc )
Also which step of the pipeline does the converted XML goes to ?
The program also expects a filename, what if I want to pass the file name dynamically ? Any ideas on this one.
Hope someone replies this time.........:)
Thanks for you help and improving my knowledge
Thanks
Advait Gode.Hi Advait,
Let me give you a small overview on how inbound IDOCs work before answering your question-
The control record is the key in identifying the routing of the IDOC. If you try to think IDOCs as normal mails(post), the control record is the envolope. It contains information like who the sender is and who the receiver should be and what the envelope contains (no different than receiving mails/letters by post).
Then the data records contain the actual data, in our example would be the actual letter. The status records contain the tracking information.
Traditionally SAP's IDOC interface (even before XI comes in picture) has utility programs to post incoming IDOCs in to SAP. One such program is RSEINB00 which basically takes the IDOC file name and the port as input. This program opens the file and posts the contents to the SAP IDOC interface (which is a set of function modules) via the port. The idea is to read the control record and determine the routing and further posting to application. Note that one information in the control record is the message type/idoc type which decides how the data records need to be parsed.
Now in XI scenario, what happens if we receive data as flat file? Normally, we use flat file adapter and in the file adapter we provide information on how to parse the file. But, if the incoming file is flat and in IDOC structure, why do we have to configure the file adapter, when the parsing capability is already available using RSEINB00/Standard IDOC interface.
This the reason, the guide suggests you to use RSEINB00. Now, your concern is what if you need to provide a dynamic filename. My idea is to write a wrapper program. This would be an ABAP program in your integration engine. This program will determine the file name (based on a logic which should be known to you) and then call program RSEINB00 using a SUBMIT/RETURN. You would then schedule this ABAP program in background to run in fixed schedules.
There are other ways of handling your scenario as well but from limited information from your request, I will stop with this now. Post me if you have any more queries.

Want to retrieve null value from xml?
i m writing this code to get the tag name and values from xml file.
Now the problem is that
if my xml file contain any tag whose value is not defined like
<root>
<firsttag>first</firsttag>
<Second></Second><Third>third</Third>
</root>
Now look if second tag doesnt contain anything ,then i want to add "null" to vector,but it throws null pointer exception because second tag is empty.
Vector<String> CSWFinfo = new Vector<String>();
try {
DocumentBuilderFactory factory = DocumentBuilderFactory
.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(new File(xml));
Element root = doc.getDocumentElement();
NodeList node = root.getChildNodes();
for (int i = 0; i < node.getLength(); i++) {
Node currentNode = node.item(i);
if (isTextNode(currentNode))
continue;
CSWFinfo.addElement(currentNode.getNodeName());
if (null != currentNode.getFirstChild().getNodeValue()) {
CSWFinfo.addElement(currentNode.getFirstChild()
.getNodeValue());
} else {
CSWFinfo.addElement("null");
}//end of for loop block
System.out.println(CSWFinfo);
} catch (Exception e) {
e.printStackTrace();
// TODO: handle exception
}I am using dom parser .
Can any one know how to do it????
Edited by: chauhan2003 on 16 Jun, 2008 12:06 PMAre you sure that all currentNode have a firstChild ????
If your node has no value, it has no child
So i 'd change code to like look something like:
if (currentNode.getFirstChild() != null) {
CSWFinfo.addElement(currentNode.getFirstChild().getNodeValue());
} else {
CSWFinfo.addElement("null");

How to avoid the null values from xml publisher.
I am creating a report which have the claim numbers with the values CLA001,CLA111,null, null . when i preview my report it is showing some spaces for null values also. How can i avoid the spaces from the report.
I am giving for loop for the claim numbers in the template.
<?for-each:ROW?> <?sort:CLAIMNUMBER;'ascending';data-type='text'?>
<?CLAIMNUMBER?>
<?end for-each?>
Please help me out to solve this problem.
Thanks,
vasanth.Hi Sheshu,
According to your description, you are experiencing the null values and infinity values when browser the calculated measure, right?
Based on my research, the issue is caused by that dividing a non-zero or non-null value by zero or null. In this cases, we need to check for division by zero to avoid this situation. Here is the sample query for you reference.
IIF(
Measures.[Measure B]=0,null,
Measures.[Measure A] / Measures.[Measure B]
If you have any questions, please feel free to ask.

XML Element to string conversion returning null
Hi,
When i try to convert XML Element to string using toString() API, it returns something like [device: null] where device is element tag.
Code is as follows -
Document xmlDoc;
DOMParser parser = (DOMParser)Class.forName("org.apache.xerces.parsers.DOMParser").newInstance();
parser.setFeature( "http://apache.org/xml/features/dom/defer-node-expansion", true );
parser.parse(new InputSource(new StringReader(tableStr)));
xmlDoc = parser.getDocument();
Element root = xmlDoc.getDocumentElement();
NodeList nodeList = root.getElementsByTagName("device");
Element deviceNode = (Element)nodeList.item(nodeList.getLength()-1);
System.out.println(deviceNode.toString()); //prints [device: null] ????
System.out.println(deviceNode.getAttribute("ipAddress")); //prints correct ip address
Any idea why i am getting [device: null] when trying to convert Element to String though attribute value is retrieved.
Thanks,

Need help Take out the null values from the ResultSet and Create a XML file
hi,
I wrote something which connects to Database and gets the ResultSet. From that ResultSet I am creating
a XML file. IN my program these are the main two classes Frame1 and ResultSetToXML. ResultSetToXML which
takes ResultSet & Boolean value in its constructor. I am passing the ResultSet and Boolean value
from Frame1 class. I am passing the boolean value to get the null values from the ResultSet and then add those
null values to XML File. When i run the program it works alright and adds the null and not null values to
the file. But when i pass the boolean value to take out the null values it would not take it out and adds
the null and not null values.
Please look at the code i am posing. I am showing step by step where its not adding the null values.
Any help is always appreciated.

Looks like you're using the Sun Java Parser. I'll show you how to do it with the Oracle XML Parser and you can extrapolate...
Document doc = new XMLDocument();
// Stuff here to build up the DOM Doc
// with elements, etc.
// Print the Document to a String
StringWriter sw = new StringWriter();
// Wrap the stringwriter in a printwriter
PrintWriter pw = new PrintWriter(sw);
// Print to the printwriter
((XMLDocument)doc).print(pw);
// return the string from the stringwriter
return sw.toString(); -
Discussion of xml representation types
I have a discussion with a college about representations of xml data to be passed between webservice and client applications.
My Suggestion: org.w3c.dom.Document - as it appears most "modern" ways/apis or parsing xml take this as a native input and there would be no need to convert to an inputSource or other type.
Other Suggestion: A String object - supposedly because it is generic enough to be used by others.I would still follow the standards. Serialize the XML to bytes. I don't see any point in treating so-called "internal" applications differently, it just makes it harder for people to maintain them in the future.
Besides, there's a rule that I call the "HMS Pinafore" rule of system design:
Chorus: What, never?
Singer: No, never!
Chorus: What, NEVER?
Singer: ... Hardly ever. -

Create xml file with values from context
Hi experts!
I am trying to implement a WD application that will have some input fields, the value of those input fields will be used to create an xml file with a certain format and then sent to a certain application.
Apart from this i want to read an xml file back from the application and then fill some other context nodes with values from the xml file.
Is there any standard used code to do this??
If not how can i do this???
Thanx in advance!!!
P.S. Points will be rewarded to all usefull answers.
Edited by: Armin Reichert on Jun 30, 2008 6:12 PM
Please stop this P.S. nonsense!Hi,
you need to create three util class for that:-
XMLHandler
XMLParser
XMLBuilder
for example in my XML two tag item will be there e.g. Title and Organizer,and from ur WebDynpro view you need to pass value for the XML tag.
And u need to call buildXML()function of builder class to generate XML, in that i have passed bean object to get the values of tags. you need to set the value in bean from the view ui context.

Hi,
For some queries of mine (those with joins and foreign keys) the sql_XXX.Result shows me "---" and "NA" at some nodes. To remove this I have been built another XML Document and using the Repeat Action to changing this value to "".
It works very well for me, but I would like to know if there is a way to change this directly on sql_XXX.Result before linking with the Output parameter of transaction.
Thank you in advance,
Nuno CunhaWhat you are describing is how MII conveys null values from the database inside the XML results (which is essentially a structured string). The dashes are for string fields, NA is for numerical columns, and TimeUnavailable will be for datetime fields.
This is expected behavior and should be consistent for the corresponding data types. If you prefer to have an empty node then I would recommend using the case statement in your SQL query template to check for the IS NULL situation and adjust accordingly.
The applets will work in conjunction with the null representations in the data, so a lot of you decision relates to the end result from a UI perspective, but dealing with nulls at the query level will be way more efficient than some repeater loop and replace mechanism in your TRX. -
Hi ,
I have a system that loads your properties trough a class that reads an xml file. For example ans sysconfig.xml that holds all of the system properties. Now, i need to load xml properties to another class, for example an class that read files from another application, and i need to store password, login, path, etc..
What is the best approach to create an generic class that receives an string that represents an xml and load it?
Is too ugly receives an String with the name of xml to load??
Thanks for suggestions..This is my method that loads the xml configuration:
private synchronized void loadPropriedades() throws FileException {
if (propriedades != null) {
return;
try {
DocumentBuilder db = JAXPFactory.getInstance().getFactory();
Document xml = db.parse(getClass().getResourceAsStream(
"/.xml"));
NodeList nodeListPrincipal = xml.getElementsByTagName("Config");
NamedNodeMap atributos = nodeListPrincipal.item(0).getAttributes();
Node nodeAtual = null;
propriedades = new HashMap();
for (int f = 0; f < atributos.getLength(); f++) {
nodeAtual = atributos.item(f);
propriedades.put(nodeAtual.getNodeName(), nodeAtual
.getNodeValue());
} catch (SAXException sae) {
Log.error("Erro na leitura do XML de configurações do sistema", se);
} catch (ParserConfigurationException pace) {
Log.error("Erro ao traduzir XML de configurações do sistema", pce);
} catch (IOException ioe) {
Log.error("Erro na abertura do XML de configurações do sistema",
ioe);
} catch (Exception e) {
Log.error(e);
My idea is transform the method above to something like private synchronized void loadPropriedades(String XmlReceived) <----------------------------------- To avoid create one class to each xml, make a class to load, but i dont know if receives a String with xml name is good...
Understand?
Thanks ! -
I have the following XML file and the java file to read the xml contents.
I compiled the java file.When i read it it says,
parsing error line 0, uri null
d:\book.xml not found.
the xml and java file are in same path only. whats the problem?
following is the code:
java file
import java.io.File;
import org.w3c.dom.Document;
import org.w3c.dom.*;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;
import org.xml.sax.SAXException;
import org.xml.sax.SAXParseException;
public class ReadAndPrintXMLFile{
public static void main (String argv []){
try {
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
File fobj=new File("D:\\book.xml");
System.out.println("file :"+fobj);
Document doc = docBuilder.parse(fobj);
// normalize text representation
doc.getDocumentElement ().normalize ();
System.out.println ("Root element of the doc is " + doc.getDocumentElement().getNodeName());
NodeList listOfPersons = doc.getElementsByTagName("person");
int totalPersons = listOfPersons.getLength();
System.out.println("Total no of people : " + totalPersons);
for(int s=0; s<listOfPersons.getLength() ; s++){
Node firstPersonNode = listOfPersons.item(s);
if(firstPersonNode.getNodeType() == Node.ELEMENT_NODE){
Element firstPersonElement = (Element)firstPersonNode;
NodeList firstNameList = firstPersonElement.getElementsByTagName("first");
Element firstNameElement = (Element)firstNameList.item(0);
NodeList textFNList = firstNameElement.getChildNodes();
System.out.println("First Name : " + ((Node)textFNList.item(0)).getNodeValue().trim());
NodeList lastNameList = firstPersonElement.getElementsByTagName("last");
Element lastNameElement = (Element)lastNameList.item(0);
NodeList textLNList = lastNameElement.getChildNodes();
System.out.println("Last Name : " + ((Node)textLNList.item(0)).getNodeValue().trim());
NodeList ageList = firstPersonElement.getElementsByTagName("age");
Element ageElement = (Element)ageList.item(0);
NodeList textAgeList = ageElement.getChildNodes();
System.out.println("Age : " + ((Node)textAgeList.item(0)).getNodeValue().trim());
}//end of if clause
}//end of for loop with s var
}catch (SAXParseException err) {
System.out.println ("** Parsing error" + ", line " + err.getLineNumber () + ", uri " + err.getSystemId ());
System.out.println(" " + err.getMessage ());
}catch (SAXException e) {
Exception x = e.getException ();
((x == null) ? e : x).printStackTrace ();
}catch (Throwable t) {
t.printStackTrace ();
}//end of main
FOllowing is the XML file:
<?xml version="1.0"?>
<book>
<person>
<first>Kiran</first>
<last>Pai</last>
<age>22</age>
</person>
<person>
<first>Bill</first>
<last>Gates</last>
<age>46</age>
</person>
<person>
<first>Steve</first>
<last>Jobs</last>
<age>40</age>
</person>
</book>I have the following XML file and the java file to
read the xml contents.
I compiled the java file.When i read it it says,
parsing error line 0, uri null
d:\book.xml not found.
the xml and java file are in same path only. whats the
problem?
following is the code:
java fileMalisun,
Is your java pgm. and XML file in the root directory of D: drive? By writing code as File fobj = new File("D:\\book.xml"); you indicate that the file is in the root directory of your D: drive. I just changed the following line:
File fobj=new File("D:\\book.xml");to
File fobj=new File("book.xml");and the program worked fine. I hope this helps. -
Hi, my problem is :
In my Application i want to parse an XML file with DOM parser. The problem is that in my Project "MyProject -> Project Properties -> Libraries and Classpath"
I have included some 15 libraries which are useful for my Application: ADF Faces Runtime 11, ADF Web Runtime and etc.
Problems are causing the libraries: BC4J Runtime,ADF Model Runtime, MDS Runtime Dependencies
because when added my source which is parsing an XML file stops working.The source code is:
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
File file =
new File("C:\\Documents and Settings\\ilia\\Desktop\\begin.xml");
Document doc = db.parse(file);
Element root = doc.getDocumentElement();
NodeList dots = root.getElementsByTagName("w:t");
Element firstDot = (Element)dots.item(0);
String textValue = firstDot.getFirstChild().getNodeValue();
I use DOM because i need to change some values in the XML file, but its not working neither for reading nor for writing.When debugging I see that it gets the root of the xml but " firstDot.getFirstChild().getNodeValue() " returns null and it breaks with NullPointerException. And that's only when the libraries mentioned above are added to the project. Without them it works just fine !
I don't know, it's like when added the parser validates my xml against some schema and returns null.
The xml file is very simple MS Word Document saved as .xml .But I don't think that's the problem.
Thanks in advance !
iliyaHi all,
I found the solution to my problem.The right way to parse and change an XML file with DOM parser using the Oracle XML Parser v2 should look like this:
JXDocumentBuilderFactory factory =
(JXDocumentBuilderFactory)JXDocumentBuilderFactory.newInstance();
JXDocumentBuilder documentBuilder =
(JXDocumentBuilder)factory.newDocumentBuilder();
File file = new File("c:/Documents and Settings/ilia/Desktop/begin.xml");
InputStream input =
new FileInputStream(file);
XMLDocument xmlDocument = (XMLDocument)(documentBuilder.parse(input));
System.out.println("Encoding: " + xmlDocument.getEncoding());
System.out.println("Version: " + xmlDocument.getVersion());
NodeList namespaceNodeList =
xmlDocument.getElementsByTagNameNS("http://schemas.microsoft.com/office/word/2003/wordml","t");
XMLElement namespaceElement17 = (XMLElement)namespaceNodeList.item(17);
namespaceElement17.getFirstChild().setNodeValue("someString");
