Reading XML payload from text file

Hello,
I have a text file with XML payload in it. The text file has some header information and then the XML payload. How do I read only the XML payload for processing in PI?
the structure of the text file is something like this..
Header Information
Payload
Sample:
#Datetime: 20140318-09:28:50.129
#MessageID: sample123
#Sender: TEST
#SenderParty: TEST
#ReceiverService:
#ReceiverParty: Test
#Interface: Test123
#InterfaceNamespace: http://test.com
<?xml version="1.0" encoding="UTF-8"?>
<Sample ><Header>......
Please advise.
Thank you.
Larry.

while ((ch = in.read()) > -1) {
sb.append((char) ch);
reader.close();
} catch (Exception exception) {
return sb.toString();
and u can get the xml as a resultant which u can use as input for next message mapping.

How to store data into database by reading sql statements from text file

how to write java program for storing data into database by reading sql statements from text file

Step 1: Create a property file to add various queries.
Step 2: Read the properties file using ResourceBundle
Step 3: Use the jdbc to execute the query read from the property file.
So in future if you need to change query no need do any modifications in java program. But depends on how you use the property file.

How can we read a column from text file

hai,
the Text file contains :
m1 m2 m4 89

m0 m4 m2 90
I need one array for each column
m[0]= m1,m1,m0 (first column from text file)
m[1]= m2,m2,m2 (second column from text file)
m[2]= 89,89,90 (third column from text file)
andvance thanks

If a 2D array is OK (instead of 4 separate arrays), try something like this
import java.io.*;
import java.util.ArrayList;
class FileReadColumns
public static void main(String args[]) throws IOException, FileNotFoundException
    String line;
    ArrayList lines = new ArrayList();
    BufferedReader in = new BufferedReader(new FileReader("data.txt"));
    while ((line = in.readLine()) != null) lines.add(line);
    String bits[];
    bits = lines.get(0).toString().split(" ");
    String grid[][] = new String[bits.length][];
    for(int i=0;i<grid.length;i++)grid[i] = new String[lines.size()];
    for(int i = 0; i < lines.size(); i++)
      bits = lines.get(i).toString().split(" ");
      for(int ii = 0; ii < bits.length; ii++) grid[ii] = bits[ii];
for(int i = 0; i < grid.length; i++)
for(int ii=0;ii<grid[i].length;ii++)System.out.print(grid[i][ii]+" ");
System.out.println();
System.exit(0);

Reading XML data from .pages file

Hi All!
I've been trying to get a script up and running, but frankly I'm lost. The script should read the date, lesson no, and name fields from a .pages file and then use that information to send an e-mail.
What I'm having a problem with is reading the data from the .pages file and I don't know what the best way to do it is because I'm still a novice at this.
So there are two ways I can think of:
1. Read directly from the Pages document when it is open. The problem with this is that it's a Pages template and it contains tables. Perhaps the easiest thing would be just to select certain cells directly from pages, but I have no idea how they're labeled or how to access them so I came up with a second idea. If you happen to know how to do this, I would greatly appreciate it.
2. Pages documents can be unzipped and one of the files is an xml file with a lot of tags and the data I need. I found the following post that talks about how to parse XML via an XSL stylesheet. After going through some tutorials, I got stuck because the xml itself in the Pages file is just a mess to me and I'm confused about which node to choose. In other xml docs you can see a clear, nicely laid out tabbed structure so you can at least figure out the path to the node you want. I stumbled across a nice script for TextWrangler which cleans up XML, but it just barks at the Pages file.
3. On top of that, I will need to use the name field and match that with an Address Book e-mail address. Should I change the template and make it into an address book field?
Thanks in advance,
Paul

The script should read the date, lesson no, and name fields from a .pages file and then use that information to send an e-mail.
Maybe you might want to try the following script:
tell application "Pages"
    activate
    tell foreground layer of page 1 of front document
        select (text box 1 whose vertical position < 0.5)
        tell application "System Events"
            keystroke "c" using {command down} -- ⌘C
            keystroke "a" using {shift down, command down} -- ⇧⌘A
        end tell
        set theText to the clipboard
    end tell
end tell
set TID to AppleScript's text item delimiters
set AppleScript's text item delimiters to tab
set theTextFields to text items of theText

Read in array from text file

hello,
i have managed to save the content of a 2d array to a text file, but i am a bit stuck reading it back and placing the data back into a 2d array.
i have a Scanner object that can read the the integers from the file using nextInt(), but i am not sure how to place them back into the 2d array.
i need something like:
        Scanner inputStream = null;
        try{
        inputStream = new Scanner(new FileInputStream("out.txt"));
        catch(FileNotFoundException e)
            System.out.println("out.txt not found");
            e.printStackTrace();
        for(int i = 0; i < 13; i++){
            for(int j = 0; j < 13; j++)
                matrix[i][j] = inputStream.nextInt();
        inputStream.close();but it doesnt like the for loop.
thanks

2) You may need to call inputStream.nextLine() after the inner for loop but inside the outer for loop.
3) Always, always use curly brackets "{" and "}" to enclose your for loops, while loops, if and else statements. They may seem like extra work if you are only processing one line, but they will save your life someday. Always.
4) Consider closing your scanner in a finally block.

Reading first word from text file

Hello all,
I created a program which I can type in a line and store it into a file. What I need my next program to do is read and display just the first word from each line on the text file.
Here is what I have:
import java.io.*;
public class ReadFromFile
public static void main (String args[])
     FileInputStream firstWord;
          try
              // Open an input stream
              firstWord = new FileInputStream ("FileofWords.txt");
              // Read a line of text
              System.out.println( new DataInputStream(firstWord).readLine() );
              // Close our input stream
              firstWord.close();
               System.err.println ("Unable to read from file");
               System.exit(-1);

what i would like is my program to get the first word of every line and put it in my array.
This is what i have attempted.

Read a non english word from text file

While Reading thai charater from text file which was sent by QAD(a different application),
We are reading 60 char using substr() function.
If the data is English word it reads correctly with 60 char.
But if it is in thai characters it returns more than 60 char.
In oracle all NLS Char set has been already set.
Can anyone help in this issue
thanks in advance

Maybe you should use SUBSTRC, SUBSTR2 or SUBSTR4 depending on the character set of your database. See http://download-uk.oracle.com/docs/cd/B10501_01/server.920/a96540/functions119a.htm#87068

Why does Read from Text file default to array of 9 elements

I am writing to a text file starting with a type def. cluster (control) of say 15 dbl numeric elements, that works fine I open the tab-delimited text file and all of the elements appear in the file. However when I read from the same text file back to the same type def. cluster (indicator), the read from text file defaults to 9 elements?? Is there a way to control how many elements are read from the file. This all works great when I initially use a cluster of 9 elements and read back to a cluster of 9 elements.
Solved!
Go to Solution.

From the LabVIEW Help: http://zone.ni.com/reference/en-XX/help/371361G-01/glang/array_to_cluster/
Converts a 1D array to a cluster of elements of the same type as the array elements. Right-click the function and select Cluster Size from the shortcut menu to set the number of elements in the cluster.
The default is nine. The maximum cluster size for this function is 256.
Aside: so, how many times has this question been asked over the years?

How to open saved files using 'read from text file' function

Hi everyone, I am having a hard time trying to solve the this particular problem ( probably because I am a newb to lanbview ). Anyway , I am able to save the acquired waveforms by using the 'Write to text file' icon. I did manually modify the block diagram of the 'Write to text file' icon and create the correct number of connector so as to make my program work. But now I have no idea on how to modify the block diagram of the 'Read from text file' block diagram to make my program 'open' my saved waveforms. Or i do not have to modify anything from the block diagram of the 'Read from text file'? Can anyone teach/help me connect up? Do i need the build array on the "open" page?
Here are some screenshots on part of my program
let me know if you guys would need more information / screenshots thank you!

Ohmy, thanks altenbach. oh yeah i forgot about those sub VIs. will upload them now. Was rather demoralized after reading the comments and really struck me on how weak i'm at on labview really hope to get this done. But of course i have to study through and see how it works. Actually i am going to replace those 'signal generators sub vi' with ThoughtTechonology's sample code so i can obtain data waveforms real-time using Electrocardiography (ECG) ,Electromyography (EMG ) and Electroencephalography (EEG) hopefully i can find out how to connect the sample code.
( ps . cant connect it now unless my program is working otherwise labview will crash )
( p.s.s the encoder of my biofeedback trainer already acts as an DAQ so i wont need to place an DAQ assistant in my block diagram i suppose )
The sample code of ThoughtTechnology is named as attachment.ashx.vi. too bad i cant use it and present it as my project

LabVIEW for ARM 2009 Read from text file bug

Hello,
If you use the read from text file vi for reading text files from a sdcard there is a bug when you select the option "read lines"
you cannot select how many lines you want to read, it always reads the whole file, which cause a memory fault if you read big files!
I fixed this in the code (but the software doesn't recognize a EOF anymore..) in CCGByteStreamFileSupport.c
at row 709 the memory is allocated but it tries to allocate to much (since u only want to read lines).
looking at the codes it looks like it supposed to allocated 256 for a string:
Boolean bReadEntireLine = (linemode && (cnt == 0));
if(bReadEntireLine && !cnt) {
  cnt = BUFINCR;    //BUFINCR=256
but cnt is never false since if you select read lines this is the size of the file!
the variable linemode is also the size of the file.. STRANGE!
my solution:
Boolean bReadEntireLine = (linemode && (cnt > 0)); // ==
if(bReadEntireLine) {    //if(bReadEntireLine && !cnt) {
  cnt = BUFINCR;
and now the read line option does work, and reads one line until he sees CR or LF or if the count of 256 is done.
maybe the code is good but the data link of the vi's to the variables may be not, (cnt and linemode are the size of the file!)
count should be the number of lines, like chars in char mode.
linemode should be 0 or 1.
Hope someone can fix this in the new version!
greets,
Wouter

"LabVIEW for ARM guru and bug destroyer"

I have another solution, the EOF works with this one.
the cnt is the bytes that are not read yet, so the first time it tries to read (and allocate 4 MB).
you only want to say that if it's in line mode and cnt > 256 (BUFINCR) cnt = BUFINCR
the next time cnt is the value of the bytes that are not read yet, so the old value minus the line (until CR LF) or if cnt (256) is reached.
with this solution the program does not try to allocate the whole file but for the max of 256.
in CCGByteStreamFileSupprt.c row 705
if(linemode && (cnt>BUFINCR)){
cnt = BUFINCR;
don't use the count input when using the vi in line mode. count does not make sense, cnt will be the total file size. also the output will be an array.
linemode seems to be the value of the file size but I checked this and it is just 0 or 1, so this is good
update: damn it doesn't work!
Wouter.

Trying to parse a file-read from text file.vi

I'm attempting to read a txt file that has tab separated data. In the fourth (or any) column is the only data I need. The data is a string of numbers (23.454).
I've used the Read from Text File.vi and the Read From Spreadsheet.vi and I just don't seem to have enough LV background to extract the pertinent data into a graph. any suggestions?

(It is silly to use "delete from array" if all you want is a column. The correct function is "index array")
Joe's idea above basically works fine. Here's a quick adapdation (the node before the graph is "index array" from the array palette.).

Set a timeout for "read from text file"

I Need to read from a text file on a remote pc and use the read from text file function to do this. It wotks but sometimes this pc is down causing long wait times in my vi.
Is there a way to set a timeout for the read from text file function, or is there an other solution?
Thank you

You could check that the path is valid first before you attempt to read the file. hen put the file read in a True-False case structure based on the results of the check. You can use the function "Check if File or Folder Exists" It checks whether a file or folder exists on disk at a specified path. This VI works with standard files and folders as well as files in LLB files. The function is found in the File I/O --> Advanced File Functions palette.

Read from text file vi won't read file...

I am very new to LV programming so I hope you forgive any stupid mistakes I am making.   I am using Ver. 8.2 on an XP machine.
I have a small program that stores small data sets in text files and can update them individually or read and update them all sequentially, sending the data out a USB device.   Currently I am just using two data sets, each in their own small text file. The delimiter is two commas ",,".
The program works fine as written when run in the regular programming environment. I noticed, however, as soon as I built it into a project that the one function where it would read each file sequentially to update both files the read from text file vi would return an empty data set, resulting in blank values being written back into the file. I read and rewrite the values back to the text file to place the one updated field (price) in it'sproper place. Each small text file is identified and named with a 4 digit number "ID".   I built it twce, and get the same result. I also built it into an installer and unfortunately the bug travelled into the installation as well.
Here is the overall program code in question:
Here is the reading and parsing subvi:
If you have any idea at all what could cause this I would really appreciate it!
Solved!

Hi Kiauma,
Dennis beat me to it, but here goes my two cents:
First of all, it's great to see that you're using error handling - that should make troubleshooting a lot easier. By any chance, have you observed error 7 when you try to read your files and get an empty data set? (You've probably seen that error before - it means the file wasn't found)
If you're seeing that error, the issue probably has something to do with this:
Relative paths differ in an executable. This knowledge base document sums it up pretty well. To make matters more confusing, if you ever upgrade to LabVIEW 2009 the whole scheme changes. Also, because an installer contains the executable, building the installer will always yield the same results.
Lastly, instead of parsing each set of commas using the "match pattern" function, there's a function called "spreadsheet string to array" (also on the string palette) that does exactly what you're doing, except with one function:
I hope this is helpful...
