Writer a DOM to a File

Hi guys, I need some help.
I just try to writer a DOM to a xml document. The DOM API don't hava a "marshall" method to do this?!!? I don't find a method to write a DOM into a xml document at the Java2sdk API.
Thanks.
Giscard.

You can org.apache.xml.serialize.XMLSerializer Class provided by xerces to write DOM in the file. Create XMLSerializer class object
          OutputFormat format = new OutputFormat();
          XMLSerializer x = new XMLSerializer(stream,format); // provide the stream
          DOMSerializer dom = x.asDOMSerializer();
          dom.serialize(node); /// save the node
Hope this will help you.

How can i write the DOM tree to the XML File?

Asslamo ala mn etb3a Alhoda.
My problem priefly is that i can't write the DOM tree to XML file.
I write following code to give the user the ability to input the name of data base which he want to create.
If i wrote DB name,its atrributes and its values succefully to XML file ,then i'll read it succefully to RAM.
It'll be simple DBMS.
***My code***
import javax.swing.*;
import javax.xml.parsers.*;
import org.w3c.dom.Document;
import org.w3c.dom.DOMException;
import org.w3c.dom.Element;
public class Main {
     * @param args
public static void main(String[] args) {
     // TODO Auto-generated method stub
     String DBname;
DBname=JOptionPane.showInputDialog("Enter Your Data Base Name");
OPerations O=new OPerations();
     O.creatDB(DBname);
class OPerations {
public void creatDB(String name){
     //get an empty Document
     DocumentBuilderFactory f; f=DocumentBuilderFactory.newInstance();
     try {
          builder = f.newDocumentBuilder();
          Document doc= builder.newDocument();
     //Build tree DOM With the root Node
          Element root=doc.createElement(name);
     //add the root element to thevdocument
          doc.appendChild(root);
catch (ParserConfigurationException e) {
     // TODO Auto-generated catch block
          e.printStackTrace();
}

Do an identity transformation to output it:TransformerFactory tf = TransformerFactory.newInstance();
Transformer tr = tf.newTransformer();
tr.transform(new DOMSource(doc), new StreamResult(new FileOutputStream(new File(filename))));(typed without syntax check)

Write data to multiple text files after specific size

Hello,
I wrote a code that contineously writes data to a text file. The problem is I am running this VI for long time and therefore this text file is being bigger in size e.g. more than 10MB. I want to split writing data in this text file after max 1MB size. Can anyone help ????
thanks in advance.

CMW.. wrote:
You could use the "File/Directory Info Function" in the Advanced File VIs and Function palette to check the size. If the file is too big. close it and create a new one.
I would use the Get File Position since this won't cause Windows to have to do so much. Assuming you are just writing and not setting the file position manually, this will return the size of the file in bytes (file position will always be at the end of the file).
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Control where a LabVIEW executable write it's Settings Configuration file

Is there any way to control which directory a LabVIEW executable writes it's configuration settings file to? I am using version 7.1.

I believe the INI file must be in the same directory as the executable. You can use the keys found in the LabVIEW.ini file and they will apply to your executable without any special programming on your part. That being said, you can always create a custom settings file or files anywhere you like to store configuration information specific to your application.
If we could specify some other path for the executable settings file, it would probably hurt more than help in the long run. The same directory as the executable is the only one whose existance you can be sure of..... or of whose existance you can be sure.

How to write data to an XML file present under application server

frnds: can ne one tell me, how to write data in to a file, which is present under a application server
Ex: i want to write a string data in to a file test.txt which is present under "http://localhost:8080/<some_webapp>/test.txt"
Note:i have deploted a service<some_webapp> under Tomcat/webapps dir

Very simple. A servlet can writes to that file if it has the good rights.
In the servlet get (or post) method, use a code like this:
import java.io.*;
protected void doGet(HttpServletRequest req, HttpServletResponse resp) {
try {
String filePath = this.getServletContext().getRealPath("/text.txt");//See http://java.sun.com/products/servlet/2.2/javadoc/javax/servlet/ServletContext.html#getRealPath(java.lang.String)
         PrintWriter writer = new PrintWriter (filePath);
        //or BufferedWriter out = new BufferedWriter(new FileWriter(filePath));
        writer .println("aString");
       writer.flush();
        writer .close();
    } catch (Exception e) {
       e.printStackTrace();
}Hope That Helps

Write arrays into a text file in different columns at different times

Hi,
I have a problem write data into a text file. I want to write 4 1D arrays into a text file. The problem is that I need to write it at different time and in different column (in other word, not only append the arrays).
Do you have an idea to solve my problem?
Thank you

A file is long a linear string of data (text). In order ro insert columns, you need to rewrite the entire file, because colums are interlaced over the entire lenght of the file.
So:
read file into 2D array
insert columns using array operations
write resulting 2D array to file again.
(Only if your colums are guaranteed to be fixed width AND you know the final number of colums, you could write the missing columns as spaces and then overwrite later. Still, it will be painful and inefficient, because column data are not adjacent in the file.)
LabVIEW Champion . Do more with less code and in less time .

The first binary file write operation for a new file takes progressively longer.

I have an application in which I am acquiring analog data from multiple
PXI-6031E DAQ boards and then writing that data to FireWire hard disks
over an extended time period (14 days). I am using a PXI-8145RT
controller, a PXI-8252 FireWire interface board and compatible FireWire
hard drive enclosures. When I start acquiring data to an empty
hard disk, creating files on the fly as well as the actual file I/O
operations are both very quick. As the number of files on the
hard drive increases, it begins to take considerably longer to complete
the first write to a new binary file. After the first write,
subsequent writes of the same data size to that same file are very
fast. It is only the first write operation to a new file that
takes progressively longer. To clarify, it currently takes 1 to 2
milliseconds to complete the first binary write of a new file when the
hard drive is almost empty. After writing 32, 150 MByte files,
the first binary write to file 33 takes about 5 seconds! This
behavior is repeatable and continues to get worse as the number of
files increases. I am using the FAT32 file system, required for
the Real-Time controller, and 80GB laptop hard drives. The
system works flawlessly until asked to create a new file and write the
first set of binary data to that file. I am forced to buffer lots
of data from the DAQ boards while the system hangs at this point.
The requirements for this data acquisition system do not allow for a
single data file so I can not simply write to one large file.
Any help or suggestions as to why I am seeing this behavior would be
greatly appreciated.

I am experiencing the same problem. Our program periodically monitors data and eventually save it for post-processing. While it's searching for suitable data, it creates one file for every channel (32 in total) and starts streaming data to these files. If it finds data is not suitable, it deletes the files and creates new ones.
On our lab, we tested the program on windows and then on RT and we did not find any problems.
Unfortunately when it was time to install the PXI on field (an electromechanic shovel on a copper mine) and test it, we've come to find that saving was taking to long and the program screwed up. Specifically when creating files (I.E. "New File" function). It could take 5 or more seconds to create a single file.
As you can see, field startup failed and we will have to modify our programs to workaround this problem and return next week to try again, with the additional time and cost involved. Not to talk about the bad image we are giving to our costumer.
I really like labview, but I am particularly upset beacuse of this problem. LV RT is supposed to run as if it was LV win32, with the obvious and expected differences, but a developer can not expect things like this to happen. I remember a few months ago I had another problem: on RT Time/Date function gives a wrong value as your program runs, when using timed loops. Can you expect something like that when evaluating your development platform? Fortunately, we found the problem before giving the system to our costumer and there was a relatively easy workaround. Unfortunately, now we had to hit the wall to find the problem.
On this particular problem I also found that it gets worse when there are more files on the directory. Create a new dir every N hours? I really think that's not a solution. I would not expect this answer from NI.
I would really appreciate someone from NI to give us a technical explanation about why this problem happens and not just "trial and error" "solutions".
By the way, we are using a PXI RT controller with the solid-state drive option.
Thank you.

Empty File has to write after Message Processing in File Adapter..!!

Hi,
File to File Scenario.
Once the file is processed and placed in the receiver folder, I need to generate one empty file with the original file name but with different extension (DON). This is used to indicate that the full file is written in the folder.
Example:
Original file has to write like "Output_Final.CSV"
Empty file has to be placed like "Output_Final.DON"
Is there any way I can achieve this requirement.?
Thanks

I have no clue of removing the same using Graphical mapping ..
I hope you have set the option of Write Empty File if not try this and still doesnot work
then need to look for java or ABAP mapping

How continuously write data to a txt file

hello,
first of all, sorry for bad English, but I have a problem to continuously write data to the txt file.... I have one 2D array with values of some function and based on 2 sliders (values of the sliders) i want to interpolate value using bilinear method... and after that value of the sliders, interpolated value, and value of the nearest points i wish to write to txt file ... for every 2-3 seconds perhaps it would be ideal to be formated as ::
x y f f1 f2 f3 f4
but... first i have problem with writing data, because every time it deletes old data and just write new one and it's not horizontal... I'm very very new at this (it is obvious) and any help will be very appreciative
thanks

Hi there,
May I suggest you start with the LabVIEW tutorial? Or perhaps this one?
I say that because 1) you said you're new at this, and these tutorials are great for getting started; and 2) you don't seem to understand the concept of dataflow.
A structure, such as a loop or subVI or function, cannot start executing until it has all of its inputs available. Therefore, the loop which contains your file write (bottom loop) cannot execute until your top loop is done executing, because it depends on inputs from your top loop and those inputs aren't available until the top loop is finished. Thus, your file will contain only the data from your final top loop execution. You might be thinking that your loops are executing in parallel. They are not. Your file loop is executing after your data loop has finished...that is to say, your file loop executes exactly once, after you press your stop button.
You can do two things here to fix that:
1. You can move your file write into the top (data) loop. (probably easier for now)
2. You can use a queue to transfer the data from your top (data) loop into your bottom (file write) loop. (more complex, but a better idea in the long run)
One other thing. Move the "open file" function outside the loop. Opening and closing the file in each loop iteration will cause problems. Open the file once. Write to it in each loop iteration. Close it when you're done. Like this:
Note that this is not complete code...you need to provide the data to write. This is just to show you how to set up a continuous file write.
Ok, start with the tutorials and we'll go from there.
