Ref Cursors to write to xml file

Hi,
I am relatively new and i am looking at what other professionals have to comment.
I am retriveing a ref cursor in Oracle and would like to store this information in an xml file along with another variable, as it would be easier to read/edit from an xml file rather than firing the stored procedure and picking/saving the ref cursor on every occassion that is required.
Looking for what the experts have to say about this way.
Also, i am looking at trying to implement this.
How does one write to an xml document from a ref cursor in Oracle 9i
Thank You
Any help will be appreciated.

You can not write REF Cursors directly to an XML file. One way to write REF Cursor data to an XML file would be to popoulate the Dataset using the REF Cursor and then use the XML functionality on Dataset to generate an XML file. Another way would be create an OracleDataReader and populate the XML file yourself.

Writting a XML file from a DOM with the reference to a DTD

Hi everyone,
how can I write a XML file, that has a reference to a DTD like:
<!DOCTYPE testdoc SYSTEM "testdoc.dtd">
I have a DOM that contains my XML-Data and I want to have this line in the XML File. I'm using a Transformer to write this XML stuff in the file.
Does anyone has an idea?
Thanks in advance

How Do I write an XML file using Java?

Hello there!! to everyone reading my post.
I have this project I need to do, and I have no clue where to start, I was wondering if you guys could help me out.
I need to know how to write an XML file using a Java Program, but without using a Third party library.... just using java native APIs.
I will probably take the values to construct the file from a form.
I will certainly appreciate if you could post some sample code for me.
Thank you very much in advance..

Hello there!,
I have some doubts about the Tutorial I am currently reading. correct me If I'm wrong, but the section "Write a simple XML file" teaches you how to do so using a text editor. I need to create my XML file from a running Java Program written by myself, that takes the values to build it from some variables.
If I'm totally wrong about what I'm saying, could you please point me to where I can find the information of how to do what I'm asking for, inside the tutorial.
Thank you very much,...
sincerely.

Having Oracle 9i.
One more doubt. In the speck, some constand values are there, When i write the same into file, How can i write ?.
1. l_str := ' "E27" '
or
2. l_str := ' E27 '
UTL_FILE.PUT_LINE(L_FILE_POI,l_str,TRUE);
1 case : in XML file : "E27"
In 2 case : E27
When we write a XML file through editors , we have to define the constant within quote . is it?
Which one can i use ? Or any other way is there ..

Write to XML File crashes when multiple Timed Loops present

Hello All,
It took me forever to track this bug down.
In this project we can edit operating parameters on the Host and send them down to an RT program in a cRIO-9025. The data is converted to XML and stored on the cRIO's disk.
Occasionally, the RT program would lock up and had to be rebooted.
It turns out that if you use Timed Loops , then a Write to XML File (or presumably any file write) will not return.
Attached is an example. This has 5 loops to make it crash faster, but it will eventually crash with only 2.

XML Write test.vi ‏93 KB

Hello Chris,
I know that Write to XML File fails because I put in debug code in my actual program, a flat sequence which updated an indicator, and after the crash, the indicator had not updated.
Yes, I know that it replaces the file. It's a configuration file, not data gathering. This is just an example of the bug.
FYI,
I increased the period for the loop with the file save to 500msecs and it still crashed.
I then decreased it to 50 msecs, and replaced all of the other Timed loops with While loops and it does not crash, even though the file save takes much longer than 50 msecs, average ~150msecs.
I replaced the loop with the file save with a While loop while leaving the others as Timed loops and it does not crash.
So the bug is systemic and related to a file save in a Timed Loop when there are other Timed Loops.
I'm not looking for a solution, I'm only reporting a bug in Labview. The solution is not to use Timed Loops, especially, as you point out, when there is file saving. It cost me several days of dicking around to figure it out. Maybe someone can save some time if they find this.

How to write as XML file using java 1.5

hi all,

Hi,
when I look in the JDK1.4.2 specification I don't see any write method in the Document interface.
However, your solution is the Transformer class. There you transform your DOM tree into any output you need. Your code sould look something like this:     TransformerFactory tf = TransformerFactory.newInstance();
     // set all necessary features for your transformer -> see OutputKeys
     Transformer t = tf.newTransformer();
     t.transform(new DOMSource(xmlDoc), new StreamResult(file));Then you have your XML file stored in the file system.
Hope it helps.

Read and write existing xml file trouble !

Hi everyone !
i'm trying to save hight score of user in my game by using a xml file , in my xml file has element <best_score>0<best_score/>
and my code to do it is :
XElement best=XElement.Load("Assets/best.xml");
IEnumerable<XElement> loc = best.Elements("best_score");
foreach (XElement elem in loc)
int check=Convert.ToInt32(elem.Value.ToString());
int score_user = Convert.ToInt32(scores.ToString());
if (score_user >= check)
hight_score.Text = score.ToString();
elem.Value = scores.ToString();
// what code to save this xml file after modify ?????
else
list_box.Text = check.ToString();
i down know what method can help me save my xml file after update hight score of user in this case .
Anyone has an idea to solve it for me ? please , thanks you !
sorry about my english !

Hi,
It is not recommended to update a file withing the project, so you need to store it in the IsolatedStorage.
Here is a sample to read and write file in IsolatedStorage,
XDocument xDoc;
var file = Util.ReadFile("XMLFile.xml");
if (file != null)
xDoc = XDocument.Parse(file);
var bestScore = xDoc.Element("best_score").Value;
//do calculation
xDoc.Element("best_score").Value = "200";
Util.SaveFile("XMLFile.xml", xDoc.ToString());
For the above code to work, you need to have a file named "XMLFile.xml" in your IsolatedStorage, with data as "<best_scrore>200</best_scrore>"
To read and write file:
public static class Util
public static void SaveFile(string filename, string data)
try
using (var store = System.IO.IsolatedStorage.IsolatedStorageFile.GetUserStoreForApplication())
using (var stream = new IsolatedStorageFileStream(filename, FileMode.Create, FileAccess.ReadWrite, store))
StreamWriter writer = new StreamWriter(stream);
writer.Write(data);
writer.Close();
catch (Exception)
Debug.WriteLine("Couldn't save the file.");
public static string ReadFile(string filename)
try
String data;
if (!IsolatedStorageFile.GetUserStoreForApplication().FileExists(filename)) return null;
using (var store = System.IO.IsolatedStorage.IsolatedStorageFile.GetUserStoreForApplication())
using (var stream = new IsolatedStorageFileStream(filename, FileMode.Open, FileAccess.ReadWrite, store))
StreamReader stmReader = new StreamReader(stream);
data = stmReader.ReadToEnd();
stmReader.Close();
return data;
catch (Exception)
return null;

Write Read XML Files not made in LabVIEW

I have an application that needs to be able to write and read xml files. My application needs to be able to save the files in such a format that an outside program can use the values saved in the xml file. On a system restart I need to be able to read in the values that were saved back into the program and populate the multicolumn list box it came from. My issue really is just reading it back in from the file.
I could create a way of writing the xml file with the information in the format needed for the other program. The problem really is, how do I handle reading in, and then populating controls with the information provided in the xml file with the xml file not in the LabView format.
The xml controls that have been provided by NI are not usable in this case.
Any suggestions or possible solutions would be greatly appreciated. Thank you for all of the help ahead of time.

Try LabXML.

Procedure for read/write an XML-File using UCCX9

Hi Team!
Is there someone who can explain me the procedure of reading/writing an XML-File using Cisco UCCX Rel. 9.0?
In the last couple of days I did a lot of research on the partner community as well as reading the CRS-Editor-PDFs.
But I can’t find a solution.
There are some templates available but they all didn’t seem to work.
I have two xml-files, both uploaded to “Document Management\en_us\”.
The script itself is attached to this posting.
I build that my script according to a sample script I found in the community.
From my point of view I have configured my script exactly like the sample script.
But it still doesn’t work.
I am especially interested in where to store the the appropriate files.
I would be very happy if there is someone who can explain me, what’s wrong there.
Many thanks in advance.
Kind regards
Michael

I'm experiencing the same issue [reading XML causes errors that say things from "no such file" to some odd Java exception.] I'm able to use a template XML file and after authenticating a user, transform the template into a proper XML file and then successfully save it to the en_US Doc Repository with updated values.
However, no matter what I've tried or who I've asked, the READ on the XML file so that I can actually script something that does some routing based on the value of the XML file created in my first script? Ultra fail.
I've even worked with three separate TAC IPCC engineers who were able to reproduce the issue in their test environment, but they were unable to assist. Eventually, whe pressed, I received this response from the last IPCC engineer.:
"Hello Brad,
Yes I know what I provided you with is what you already have achieved and this missing step is precisely what you need: how to setup the script to check the status and value of this XML document and then decide routing according to the state. But unfortunately this is what I found internally. The other resources are the ones you already know: support forums, scripting guides. The other resource with suggest to customer looking for script assistance is the Cisco Account Manager of your company, they know where to get the resources for such issues. Then again as I mentioned before on our phone conversation TAC does not support scripting but certainly if I find something else on my side I will let you know for sure."
I would do ponderous cartwheels of joy if someone who has this working in version 9.x [9.0.2 specifically] could share the deep magic.

How to retrieve characters like '£' from the database and write to xml file

Hi ,
I have a requirement to retrieve the data from database and write to files in XML format.
I am able to do so successfuly by using XMLElement tag and writing to file through UTL_File package.
All characters like <&@^ get converted properly, but when it comes to multibyte chars like '£', they are not able to get converted as it is.
Can somebody please advise me how to go ahead.
Regards

Thanks odie.
The nls_charset for my database is WE8ISO8859P1 and database version is Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bi.
The data (with pound sign) is sitting in one of the columns of the table and when i query it directly, I am able to view it properly.
However when I use the below code to retrieve in XML format and print it to file, it gets changed. This file is also passed to one of the application GUI where this XML gets processsed and it is not visible properly.
below id the sample abstract of code I am using.
Declare
l_file UTL_FILE.FILE_TYPE;
l_clob CLOB;
l_buffer VARCHAR2(32767);
l_amount BINARY_INTEGER := 32767;
l_pos INTEGER := 1;
Begin
SELECT XMLElement("case",
XMLElement("comments",
XMLElement("comment",
XMLElement("comments",a.COMMENTS)
).getClobVal() val1 into l_clob
FROM TO_COMMENTS a
l_file :=
UTL_FILE.fopen (XMLDIR,
test.xml,
'w',
32767);
LOOP
DBMS_LOB.read (l_clob,
l_amount,
l_pos,
l_buffer);
UTL_FILE.put_line (l_file, l_buffer);
l_pos := l_pos + l_amount;
END LOOP;
EXCEPTION
WHEN NO_DATA_FOUND THEN
DBMS_OUTPUT.NEW_LINE('Reached end of file');
END;
The comments column given contains the character like pound.
And once the file is generated and i see using the vi editor, the char is not viewable properly like Â£
And when the same is passed to GUI application to be processed, its not viewable propely in GUI from IE as well like �.

Create xml file and write data in to it:

Hi All,
I have a small requirement here.....
I have a java program which reads a xml file.
Now i have stored the contents of that file in to a java object.
I want a sample code now which would take theabove mentioned java object as an input ,create a xml file and write these entries in to the file.
Can anyone help me in this?
Your help would be appreciated.
Thanks in advance.
vrkr

Hmmm. There is nothing special about an XML file to any other file. The data is simply formatted in a certain way. So to write an XML file, it is no different to writing any other form of file in Java (assuming you know the structure of the xml format to write - which you should)
If you don't know how to write files using Java I would suggest using the Java Tutorial found on java.sun.com and do some reading up about I/O since this is fairly fundamental.
