Parse XML document ,create table according to tags & load data to table

Hi All!
I have one of the most common problem, one faces when dealing with xml stuff and oracle.I get xml documents, with each file having different tags.I want to write a pl/sql procedure such that, the xml file is parsed, a table is created with the tag names becoming the column names and all the nodes' data get inserted into the table as rows.I am using oracle 10g.
I read a thread at the following url:
Parse XML and load into table
But did not get much of it.
Can anybody please tell me how to accomplish this.
Thanking in advance.
Regards,
Deepika.

Why do people have such an aversion to the XML DB forum for XML questions...
See FAQ for XML DB forum here: XML DB FAQ
Explains all about getting XML into tables in the database.

Filling tab of an XML document created by DOM

have a problem with filling tab of an XML file created by DOM
I used this code to create the document:
public class DOMCreation {
public void createDOM( String a, String b ) {
          Document doc = new DocumentImpl( null );
          // Il codice che segue � indipendente dal particolare parser utilizzato
          // Creazione dell'elemento root del documento, identificato dal tag <DOCUMENT>
          Element root = doc.createElement("DOCUMENT");
          doc.appendChild(root);
          // Creazione ed inserimento di un nodo
          Element element1 = doc.createElement("USERNAME");
          root.appendChild( element1 );
          // Creazione ed inserimento di un secondo nodo discendente di <DOCUMENT>
          root.appendChild( doc.createElement("PIN") );
System.out.println( a );
System.out.println( b );
          try {
               serializeDocument( doc, new FileOutputStream("d:/doc.xml"));
          } catch (FileNotFoundException e) {}
private static void serializeDocument(Document doc, OutputStream output) {
          try {
               DOMSerializer ser = new XMLSerializer( output, null);
               ser.serialize(doc);
          } catch (IOException e) {
               System.err.println("I/O exception while serializing document: " + e.getMessage());
}

The code lines:
System.out.println( a );
System.out.println( b );
had the purpose to check if these two parameters were passed by another procedure. These two parameters, however, represent the content to be filled in the tag of XML document created by DOM.
About the other question on "what parser do you use", I'm using Apache's Xerces. However that's the "import" that I include in this procedure:
import org.apache.xerces.dom.DocumentImpl;
import org.apache.xerces.dom.NodeIteratorImpl;
import org.apache.xml.serialize.*;
import org.w3c.dom.*;
import org.w3c.dom.traversal.*;
import java.io.*;

Parse XML document which have xlink/xpointer inside

dear friends,
There are lots of topic talking about parse xml, validating xml with schema and so on, but no one or any book talking about parsing xml document which can parse document with link inside.
According to Mr Meggison at http://www.megginson.com/Background/
we can do it, but he is not expert with this thing.
For example I have 3 XML document. My main XML document, let named it A.XML have XPointer inside and this element pointing to B.XML and C.XML using xpointer. how to parse A.XML and in the same time my SAX recognized this XPointer and parse also element inside B.XML and C.XML.
I am really grateull for any helpful information from you.
best regards

I think you need to look for a SAX or DOM parser that undestands XPointers and knows how to follow them to additional content.
I have used XSLT and specified external documents to it. It knows how to read a document and in effect make a nodeset which can be searched with the XPath capabilities of XSLT.
It sounds like you wnat an <include file="xxx"/> capability and have the parser stop reading the current file, and start reading the second file.
That works in Schemas, but I'm unaware of any way to do it with SAX or DOM in one pass.
It would not be too hard to process the first file, say with DOM.
After the Document is built, go find the <include> elements, read get the attribute needed, build a new Document and merge it into the original Document in place of the <include> element.
Is this more what you want to do?

Can I create a Stored Procedure That access data from tables of another servers?

I'm developing a procedure and within it I'm trying to access another server and make a select into a table that belongs to this another server.

You need to have a Database Link between two servers. Then you could do execute that statement without any problem. Try to create a database link with the help of

FDMEE Import error "No periods were identified for loading data into table 'AIF_EBS_GL_BALANCES_STG'

Hi,
We are having trouble while importing one ledger 'GERMANY EUR GGAAP'. It works for Dec 2014 but while trying to import data for 2015 it gives an error.
Import error shows " RuntimeError: No periods were identified for loading data into table 'AIF_EBS_GL_BALANCES_STG'."
I tried all Knowledge docs from Oracle support but no luck. Please help us resolving this issue as its occurring in our Production system.
I also checked all period settings under Data Management> Setup> Integration Setup > Global Mapping and Source Mapping and they all look correct.
Also its only happening to one ledger rest all ledgers are working fine without any issues.
Thanks

Hi,
there are some Support documents related to this issue.
I would suggest you have a look to them.

How to insert row in table control and save the data in tables

Hi,
I have one table control i am displaying data into table control ,
my problem is : i want to display data into read mode in table control.
but when i click on insert button on the same screen i want one blank line should inserted into table control , then i want to insert some data into table control on that row , when i click the save button . the new data inserted into the table control is insert that data into ztable ,
please give me solution
main problen is how can know inserted line in table control and pass that data into ztable.

Hi,
Follow the below logic,
PROCESS BEFORE OUTPUT.
MODULE STATUS_0001.
MODULE POPULATE_TABLE_CONTROL. --> Get the data from table store in
                                                                      ITAB

       WITH CONTROL CTRL_LP_D516
       CURSOR CTRL_LP_D516-CURRENT_LINE.
The following module moves data to control
    MODULE MOVE_TO_CONTROL.--> Move data from ITAB to table control
ENDLOOP.
PROCESS AFTER INPUT.
LOOP AT GT_CTRL_LP_D516.
ENDLOOP.
MODULE EXIT AT EXIT-COMMAND.
MODULE USER_COMMAND_0001. --> Here you have to take out the values from table control and update database table

Parsing XML document with nested elements into multiple db tables(master-detail)

Can you help me with storing xml document into master-detail tables?
I have two tables:
1) customers (customerid number primary key, firstname varchar2(30),lastname varchar2(30))
2) cust_addresses (customerid number references customers, street varchar2(30),city varchar2(30),state varchar2(10),zip varchar2(10))
I have XML document:
<?xml version="1.0"?>
<ROWSET>
<ROW num="1">
<CUSTOMERID>1044</CUSTOMERID>
<FIRSTNAME>Paul</FIRSTNAME>
<LASTNAME>Astoria</LASTNAME>
<HOMEADDRESS>
<STREET>123 Cherry Lane</STREET>
<CITY>SF</CITY>

<STREET>N.Fryda 4</STREET>
<CITY>CB</CITY>
<STATE>CZ</STATE>
<ZIP>37005</ZIP>
</HOMEADDRESS>
</ROW>
</ROWSET>
I know that I must use DBSM_XMLSave package, create view and instead of trigger but I did found no example in documentation.
Thanx.

Interested question; one I do not know the answer to at the moment, I am afraid. I would like to know your results.
To tell others, though, what I have done. I did finally adapt Muench's not-yet-published examples #71 to work with a table. Here the table has as it's value "#{backing_app_EPG_DAYPG.jobDayDriverTable[row.Id1]}"
This accesses a hash map defined in the backing bean as follows:
public Map jobDayDriverTable = new HashMap(){
@Override
public Object get(Object key) {
Number jobDayId = (Number)key;
if (getEpgDayPage().jobDayDrivers(jobDayId) != null) {
return getEpgDayPage().jobDayDrivers(jobDayId).getAllRowsInRange();
else return null;
jobDayDrivers returns RowIterator. From this I call getAllRowsInRange which returns a Row[]. The table consumes this as a value, and lists the values as I want.
Since the table is using Rows for its rows, I am guessing that it would have access to #{row.rowKeyStr}, or at least #{row.<pk>} which would allow you to programmatically set the current row using code like the following:
public static boolean setCurrentRow() {
// BindingContainer bindings = getBindings();
OperationBinding operationBinding =
// bindings.getOperationBinding("setCurrentRowWithKey");
(OperationBinding)EL.get("#{bindings.setCurrentRowWithKey}");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return false;
return true;
You could call this as part of code in a pages backing bean behind a button or link.
Hope this helps somebody.
By the way example #71 was to get a detail set of rows from a master row value and display the detail set in the master row of an af:table.
You can find this and other examples at http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html

How to parse XML document returned by webservices

Hi,
I have a form (version 10.1.2.0) which has to display the credit card types using webservices. I created the webstub and jar file through jdeveloper and then after adding the jar files in the respective classpaths, I import it in the forms. I write the code in when-button-pressed and it gives the result in xml document like this:
<?xml version="1.0" encoding="UTF-8"?><WSAnswerTO><error>false</error><errorMessage></errorMessage><

From the above xml document, I only need to display the type (such as AMERICAN EXPRESS, VISA, ETC) in my forms. Can somebody please tell me how to do it. Do I need to store the values in a table first and then retrieve it. Please advise. I have already read a otn document in xml parsing but I didnt understand anything from it.
Please help. Thanks in advance.

No default attributes while Parsing XML document

Hellow.
I have such a problem:
I have XML document that uses XSD-schema.
In XSD-schema there is element that have two atributes:
<xsd:complexType name = "El1">
<xsd:attribute name = "atr1" xsd:default = "0" type = "xsd:boolean"/>
<xsd:attribute name = "atr2" default = "0" type = "xsd:boolean"/>
</xsd:complexType>And in XML document I write:
<El1 atr1 = "1"/>According to the XSD-schema parser must add to El1 second attribute "atr2" with its default value because it has default value. But when I do such a code:
factory = DocumentBuilderFactory.newInstance();
builder = factory.newDocumentBuilder();
doc = builder.parse(new File("file1.xml"));
Element pEl;
pEl = doc.getDocumentElement()
NamedNodeMap Attribs = pEl.getAttributes();In the list of attributes "Attribs" - there is no attribute "attr1"!!!
What I have to do???

Hello All
I am new to this parsing world. I have a doubt. I have an XML like
<xml>
<platform name = "windows">
<computer>
<hostname> hostname1 </hostname>
<IPAddress>127.0.3.03 </IPAddress>
</computer>
<computer>
<hostname> hostname2 </hostname>
<IPAddress>127.0.3.04 </IPAddress>
</computer>
</platform>
<platform name = "unix">
<computer>
<hostname> hostname6 </hostname>
<IPAddress>127.0.3.08 </IPAddress>
</computer>
<computer>
<hostname> hostname7 </hostname>
<IPAddress>127.0.3.09 </IPAddress>
</computer>
</platform>
</xml>
If i want to get details about individual computer under each platform as a string how do i do that?
Which parser would be ideal to be used DOM or SAX.

hi this my xml document.i trying to parse this document..
i need to display the id and name values of each objectstore tag in a select box
id as option value and name as option text.
iam doing like this..
e = doc.getDocumentElement();
list = e.getElementsByTagName("name");
for(int i = 0; i < list.getLength(); i++)
n = list.item(i);
if(n.hasChildNodes())
list2 = n.getChildNodes();
for(int j = 0; j < list2.getLength(); j++)
n2 = list2.item(j);
String name =n2.getNodeValue();
                                                  out.println(name);
it displaying the name but also its displaying the value which is name tag of property element..how can i avoid this..
regards,

as <id> is a child of <ObjectStore> it would seem that you should getElementsByName("ObjectStore") first, then find the id and name children.

Problem with XML document created by JDBC Sender adapter

We are using a sender JDBC adapter to publish data out of a DB2 table. The message generated by the XI sender adapter seems to have 2 extra characters that break our mapper. You can see the characters (the dashes on lines 2 and 4) in the XML document that I copied from message monitoring. Once I remove these dashes and test the mapper in test mode, it works. If I test with the dashes, the mapper fails. Has anybody else seen this issue?

Hi Ivailo,
I think the problem lies in the way you copy the data from monitor.
whenever you want to copy data from XI monitor to test in your IB,make sure you select "view source" and then copy the source message otherwise you will get the browser view of the XML document which contain those "-" for expanding and collapsing the document.

Is there a white space problem? How do I get rid from this problem.

ok now i really wrote the whole code, a bit scrolling in the API is to hard?
            DocumentBuilderFactory dbf = new DocumentBuilderFactory();
            DocumentBuilder db = dbf.newDocumentBuilder();
            dbf.setNamespaceAware(true); //or set false
            Document d = db.parse(inputstream);

Parse xml document with xpath

I would like to parse an xml document using xpath, see:
http://www.onjava.com/pub/a/onjava/2005/01/12/xpath.html
however, in the documentation (in the link above), it states that I need J2SE 5.0.
Currently, I have:
$ java -version
java version "1.5.0_11"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_11-b03)
Java HotSpot(TM) Client VM (build 1.5.0_11-b03, mixed mode, sharing)
Does that mean that I really have to install J2SE 5.0 in order to use J2SE 5.0's XPath support? Does anybody know anything about getting started with XPath, and whether I can just use my existing version of Java? I've never used XPath.
For more documentation, one can view:
http://www.w3.org/TR/xpath20/
Thank you.

I have copied the code for the xpath tutorial on
http://www.onjava.com/pub/a/onjava/2005/01/12/xpath.html
exactly as it is on the tutorial, and imported the correct jars (I think).
But still my code is giving lots of errors!
Granted its my first shot but anyway here's the code and the errors...

Using parser to parse xml document

Hi all:
I have a xml document which has a root element and the a list of elements(same type) underneath it.
My question is:
Is there a restriction on the number of elements(same type) that you can extract from the Document?
Thanks.
Rino

If you use DOM of JDOM, you will have a problem when you run out of system memory.
If you use SAX, the parser will throw events with the required data for the current node (element, data, attribute). Once the event has been processed, the data is out of scope (unless you still hold a reference to it).
If you use SAX, you are able to process each node without keeping the data from that node any longer than you like. Unless you have to have the entire document available, I would suggest using SAX.

Parse XML document ,create table according to tags & load data to table
