Population of Oracle DBs from XML?

Forgive me if I haven't fully understood Oracle's new XML parser
for Java, but is it possible to >>directly<< populate an Oracle
database from an XML file or do you have to use the Java parser.
As a developer using Delphi it would be most useful to have a
generic XML to table converter build into Oracle. As far as I
can see the only way at the moment to do this is throgh the Java
VM. Correct me if I'm wrong.
Any comments on this thread would be most appreciated.

Populating a Crystal Report from XML data

Hi,
I want to populate a Crystal Report using a XML data structure. Below I have explained what Iu2019m trying to do in detail,
u2022 First I will create a Crystal Report using Crystal Report XI R2 designer by connecting to a Oracle database using a native Oracle connection (not ODBC or JDBC)
u2022 Then I want to write a Java application using CR XI R2 JRC SDK to open this report
u2022 Then to run and populate this report using a XML data structure (which I have separately in a disk location. XSD too is available in disk)
u2022 Then to export this report with data to either PDF or RPT file with saved data in to disk.
The questions I have are,
1. Is this possible to do in away?
2. If so, can you please provide me with a sample code for doing this? I tried some of the other threads in the forum but some had broken links.
3. Do the xml and the xsd needs to be in a special format?
4. Is there any other configuration setting I should do?
Hope you can help me. Thank you in advance.
Regards,
Chanaka

Hi Chinmay,
Thank you for the prompt answer. I have gone through this before. It explains on how to create a report using a xml database from CR designer. What I want to do is to set the data source programmatically to a xml date source from the code. I didnu2019t find anything like that. Is it the same way as setting the database connection information?
Also another question I have is how does a report with two tables work? Say I have a master u2013 detail report (order and order lines). The master part is taken from one table (order_tab) and the detail part is taken from another (order_detail_tab). Do I need to have 2 xmls or is one structured xml sufficient? How will the same work if I have the detail section in a sub-report? Will it work with one or do I need to have two?

Chanaka

Insert data into oracle table from XML script not working

Hi,
I wrote simple PL/SQL program to extract values from a XML file and disply all the employee names. But the first employee name repeating. Please can you tell me how to fix it.
set serveroutput on size 2000;
declare
indoc VARCHAR2(2000);
indomdoc dbms_xmldom.domdocument;
innode dbms_xmldom.domnode;
myParser dbms_xmlparser.Parser;
l_nl dbms_xmldom.DOMNodeList;
lv_value varchar2(30);
l_n dbms_xmldom.DOMNode;
begin
indoc := '<emp> <name> Scott </name>
<name> Tiger </name>
</emp>';
myParser := dbms_xmlparser.newParser;
dbms_xmlparser.parseBuffer(myParser, indoc);
indomdoc := dbms_xmlparser.getDocument(myParser);
innode := dbms_xmldom.makeNode(indomdoc);
l_nl := dbms_xslprocessor.selectNodes(dbms_xmldom.makeNode(indomdoc),'/emp/name');
dbms_output.put_line('Record count '||dbms_xmldom.getLength(l_nl));
FOR cur_emp IN 0 .. dbms_xmldom.getLength(l_nl) - 1 LOOP
l_n := dbms_xmldom.item(l_nl, cur_emp);
lv_value := dbms_xslprocessor.valueOf(l_n,'//name/text()');
dbms_output.put_line('Emp Name : '||lv_value);
END LOOP;
end;
/

Based on an earlier example of mine from {message:id=2826611}
This works in 10.2.x.x for sure. I can't recall (didn't look up) whether in 10.1 it allowed for going straight from a CLOB to a DOMDocument via newDomDocument.
declare
   indoc    VARCHAR2(2000);
   indomdoc dbms_xmldom.domdocument;
   l_nl     dbms_xmldom.DOMNodeList;
   lv_value VARCHAR2(30);
   l_n      dbms_xmldom.DOMNode;
   l_xmltype   XMLTYPE;
   l_index     PLS_INTEGER;
begin
   indoc := '<emp> <name> Scott </name>
   <name> Tiger </name>
   </emp>';
   indomdoc := dbms_xmldom.newDomDocument(indoc);
   l_nl := dbms_xslprocessor.selectNodes(dbms_xmldom.makeNode(indomdoc),'/emp/name');
   dbms_output.put_line('Record count '||dbms_xmldom.getLength(l_nl));
   -- Method 1
   FOR cur_emp IN 0 .. dbms_xmldom.getLength(l_nl) - 1 LOOP
      l_n := dbms_xmldom.item(l_nl, cur_emp);
      lv_value := dbms_xmldom.getnodevalue(dbms_xmldom.getfirstchild(l_n));
      dbms_output.put_line('Emp Name : '||lv_value);
   END LOOP;
   dbms_xmldom.freeDocument(indomdoc);
   -- Method 2
   dbms_output.new_line;
   l_xmltype := XMLTYPE(indoc);
   l_index := 1;
   WHILE l_xmltype.Existsnode('/emp/name[' || To_Char(l_index) || ']') > 0
   LOOP
      lv_value := l_xmltype.extract('/emp/name[' || To_Char(l_index) || ']/text()').getStringVal();
      dbms_output.put_line('Emp Name : '||lv_value);
      l_index := l_index + 1;
   END LOOP;

Porting data from Oracle8i to XML and from XML to Oracle 10g

Hai
I have a client database (using oracle 8i) and a server database (oracle 10g).
Due to lack of leased line connectivity i want to port these offline data from 8i to 10g
using a modem(dial up connection).Is there is any way to port data from 8i to XML
and from XML to 10g.
thanks in advance
dejies

Thanks Nicolas,
As per documentation, it seems to be difficult for export/import from Oracle8i to 10g. Is that any way to achieve this? I have to append the newly imported data with old or exisiting data into Oracle10g.

Populating a SELECT list from an Oracle Table

Hello,
I would like to populate a second SELECT list on
a web page based on the selected value in the first
SELECT list. I would like to take the value
that the user selects in the first SELECT list and
use it in a WHERE clause to bring back distinct
values to display in the second SELECT list.
I would like to do this all on a single page. As
soon as the user selects a value in the first SELECT
list, then the correct values retrieved from the
database would appear in the second select list.
Is this possible? Do you have sample code or ideas??
I can write JavaScript to get the selected value, but
I cannot get to Oracle data from the JavaScript environment.
I can write PL/SQL or Java procedure to access
Oracle data, but I cannot make the complete connection.
Help, please.
thanks
paul

Unless you can get every combination back in the first SQL statement, you'd have to do something along the lines of
- Have the JavaScript submit the page as soon as the first pull-down is selected
- Have the response be a page identical to the first page, but with the second pull-down populated.
The other option would be to have a Java applet that can make the second query and return results. Since applets can't connect to the database by default, you'd have to have an app server that would do the actual query.

Extract data from XML file to Oracle database

Dear All
Please let me know, how to extract data from XML file to Oracle database which includes texts & images.
Thanking You
Regards Lakmal Marasinghe

I would do it from the database, but then again, I am a database / PL/SQL guy.
IMHO the database will deliver you with more options. I don't know about "speed" between the two.

Populating listitem from xml

I am new to Forms but I am having to learn quickly. I need to populate a listitem from XML.
The XML already exists (is response from calling REST web service) and is in a variable.
Is there a simple way of scrolling through this xml file and extracting just the element values e.g. postcode and using these to populate a listitem?
in .net it is very easy, it seems very hard in Oracle :(
the xml is
<?xml version="1.0" encoding="UTF-8"?>
<al_qb_api_response>
<addresses>
<address>
<id>normal:BOGBBDAzYBwMDAQAAmheiAAAAAAAzNABkAA--</id>
<type>normal</type>
<line>34 Collin Avenue, Erith, Kent</line>
<postcode>DA8 1EE</postcode>
</address>
<address>
<id>normal:COGBBDAzYBwMDAQAAn3ZYAAAAAAAzNABkAA--</id>
<type>normal</type>
<line>34 Collin Avenue, Sidcup, Kent</line>
<postcode>DA15 9DW</postcode>
</address>
</addresses>
</al_qb_api_response>
thank you.

in .net it is very easy, it seems very hard in Oracle :(I don't think its so hard in oracle, you simply need some additional steps.
First, build your code to extract the desired information from the xml-file using Java and the JDeveloper. This should be quite similar to the way you do it in .net . Then, build one method on top of that extraction code which returns a string-array (exactly the values you want to assign to your listitem). Then you can use the forms-java-importer to create a PL/SQL-wrapper around this java-class and simply use the resulting code in PL/SQL in forms.

Storing data from XML files in Oracle DB

Hi!
I just started to work with XML and need to save data from XML files into Oracle database. I tried to run sample from Oracle web site. The code was following:
public class xmlwritedb
public static void main(String args[]) throws SQLException
String tabName = "EMP"; // Table into which to insert XML data
String fileName = "emp.xml"; // XML document filename
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
// Initialize a JDBC connection
Connection conn =
DriverManager.getConnection("jdbc:oracle:oci8:scott/tiger@");
// Insert XML data from file (filename) into
// database table (tabName)
OracleXMLSave save = new OracleXMLSave(conn, tabName);
URL url = save.createURL(fileName);
int rowCount = save.insertXML(url);
System.out.println(" successfully inserted "+rowCount+
" rows into "+ tabName);
conn.close();
But it does not work.
OracleXMLSave object does not see file name.
Please, help me solve this problem. Also,where is it possible to find any documentation on oracle.xml.* classes API.
Thank you.
Maya.

Remove XML tags from XML element in Oracle

Hi,
I have a requirement where I have to remove all the xml tags from xml element with banks, currently I'm using replace 4 times to replace all different types of xml tags, performance is really bad. is there any better option to remove xml tags from xml data leaving the actual data. please find the example data below.
select
TO_CLOB(REPLACE(REPLACE(REPLACE(REPLACE
('<Concatcolumn><ConcatGroupID>MyText Data goes here </ConcatGroupID><ConcatGroupID>Data agian</ConcatGroupID></Concatcolumn>','<ConcatGroupID>'),'<Concatcolumn>'),'</ConcatGroupID>',';'),';</Concatcolumn>')) AS Concatcolumn
from dual
**************Out put*************
MyText Data goes here ;Data agian

One way is to use xquery:
SQL> with t as
select xmltype('<Concatcolumn>
                      <ConcatGroupID>MyText Data goes here </ConcatGroupID><ConcatGroupID>Data agian</ConcatGroupID></Concatcolumn>'
   ) xml from dual
select xmlquery('string-join(//text(), ";")' passing xml returning content).getclobval() xml from t
XML
MyText Data goes here ;Data agian
1 row selected.
