How to search a special string in txt file and return it's position in txt file?

I just posted a solution for a similar question here: http://forums.ni.com/ni/board/message?board.id=170&view=by_date_ascending&message.id=362699#M362699
The top portion can search for the location of a string, while the bottom portion is to locate the position of a character. Both can search for a character.
The position of the character within the file is displayed in the indicator(s).

Search and replace strings in a file while ignoring substrings

Hi:
I have a java program that searches and replaces strings in a file. It makes a new copy of the file, searches for a string in the copy, replaces the string and renames the new copy to the original file, thereafter deleting the copy.
Now searching for "abcd", for eg works fine, but searching for "Topabcd" and replacing it doesnot work because there is a match for "abcd" in a different search scenario. How can I modify the code such that if "abcd" is already searched and replaced then it should not be searched for again or rather search for "abcd" as entire string and not if its a substring of another string.
In the below code output, all instances of "abcd" and the ones of "Topabcd" are replaced by ABCDEFG and TopABCDEF respectively, whereas according to the desired output, "abcd" should be replaced by ABCDEFG and "Topabcd" should be replaced by REPLACEMEFIRST.
try
          String find_productstring = "abcd";
          String replacement_productstring = "ABCDEFG";
          compsXml = new FileReader(compsLoc);
          compsConfigFile = new BufferedReader(compsXml);
          File compsFile =new File("file.xml");
          File compsNewFile =new File("file1.xml");
          BufferedWriter out =new BufferedWriter(new FileWriter("file1.xml"));
          while ((compsLine = compsConfigFile.readLine()) != null)
                new_compsLine =compsLine.replaceFirst(find_productstring, replacement_productstring);
                out.write(new_compsLine);
                out.write("\n");
            out.close();
            compsConfigFile.close();
            compsFile.delete();
            compsNewFile.renameTo(compsFile);
        catch (IOException e)
        //since "Topabcd" contains "abcd", which is the search above and hence the string "Topabcd" is not replaced correctly
         try
               String find_producttopstring = "Topabcd";
               String replacement_producttopstring = "REPLACEMEFIRST";

Conversion of xml string to xml file

To convert xml string to xml file in java i used
Document XMLDoc=DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(new InputSource(new StringReader("<root><main>Title</main></root&g t;")));
But it is showing an error as InputSource cannot be resolved
How to rectify this

I assume you mean there is a compiler error? (It helps if you explain your problem instead of just giving a vague description of it.) It sounds like you have to import InputSource. You do know about the import statements that go at the beginning of a Java class, don't you?

How to save string in a file with special-chars

Hello,
i´m usingthe MD5-llb to create a password.
Then i want to save this MD5-string to a file and later read it back abd compare.
Works perfect with one proplem:
Some word create a "\r" in the MD5-string and when i save this string to a file and read it back then its read back as a "\n" so that the compare is not working.
My question is: How can i save a string exactly like it is to somewhere and read it back (also invisible chars)
For example the word: heinz
is in MD5: \r\FB^\07\A6\07T\C7\D9\C2\94\AB\C9\1DS\95 (string indicator as codes display)
when i save the string to a file then i rerad back: \n\FB^\07\A6\07T\C7\D9\C2\94\AB\C9\1DS\95
I used the "write text file" and "read text file"
What do i have to use to save and read the same?
Thx
Solved!
Go to Solution.

I believe an MD5 hash is 16 bytes long. Use the binary read and write file I/O functions and specify the length of the data to be read or written.
Now is the right time to use %^<%Y-%m-%dT%H:%M:%S%3uZ>T
If you don't hate time zones, you're not a real programmer.

Problem in outputting a string into a file

Hi guys,
I tried to output a string to a file. The string is 'Size : 30u201D X 13 ½u201D X17 ¾u201D(H)'.
However, with this code :
l_file = '/erp/reports/testgk.txt'.
l_str = 'Size : 30u201D X 13 ½u201D X17 ¾u201D(H)'.
OPEN DATASET l_file FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.
TRANSFER l_str TO l_file.
It returned me a weird string: 'Size : 30M-bM-@M-] X 13 M-BM-=M-bM-@M-] X17 M-BM->M-bM-@M-](H)'
Would you please let me know how to solve this problem?
Thanks, gk

Hello gk,
I tried this code & works fine for me though:
DATA: v_data TYPE string VALUE ' 30u201D X 13 ½u201D X17 ¾u201D(H)',
v_file TYPE string VALUE
'\glbwi720InterfaceID2100I_MB_207INsdn.txt'.
OPEN DATASET v_file FOR OUTPUT
IN TEXT MODE
ENCODING DEFAULT.
IF sy-subrc = 0.
TRANSFER v_data TO v_file.
CLOSE DATASET v_file.
ENDIF.
Looks like the "usual" ENCODING problem

How to convert xml String to xml file?

Hi,
I got a method that do the following:
public static String convertXmlToString(String xmlFileName) throws Exception
        File file = new File(xmlFileName);
        FileInputStream insr = new FileInputStream(file);
        byte[] fileBuffer = new byte[(int)file.length()];
        insr.read(fileBuffer);
        insr.close();
        return new String(fileBuffer);
     }The return String is the contents of an existing xml file and one example is shown below:

Hope there's a method to do that

Strange repeating strings in multiple files possible virus?

A few months ago when I ran netstat I noticed about 10 TCP ports that said: Local Address [::]:5000, Foreign Address [::]:0, all were just listening. I ran the netstat with -noa to get the PIDs and resolved the issue, but when I started digging around in
some files I started to notice something weird.
In probably around 100 files there are these repeating strings. A few of them are: @VWATAVH, WATAUH, SUVWH, @UATAUAVAWH, SVWATH, @SUVWATAUAVAWH...
I use a program called Bintext that lets me see all of the strings inside a file. After seeing these strings repeatedly I realized that I have some kind of trojan/virus/keylogger/whatever. I have found these same strings in files going back to 2010 up until
the most recent around a week ago.
I finally did a comparison tonight of the file ntdll.dll and I was shocked at the difference of the two files. I downloaded another copy of ntdll.dll from dll files.com. The original file from my computer is 1.23MB and version 6.1.7601.17725. The other file
which hasn't been changed is 1.65MB and version 6.1.7601.17725, the exact same version as the one I already had.I
I used the program bintext to make text files of the two files, then I used the website diffchecker.com to compare the two files. Check it out: https://www.diffchecker.com/dl8jqoye (I couldn't do a link until my account is verified)
Some of the other files that are suspect are: comct32dll, crypt32dll, exe_94123cfe, iwrapexe, unsexe, Riconman, ntdll, and so many others I ran across before I started keeping track. Most of the files that contain these weird strings also reference a small
group of other files as well: wbemcomn.dll, ntdll.dll, msvcrt.dll, KERNEL32.DLL, RPCRT4.dll, USER32.DLL, advapi32.dll, and unsecapp.dll.
I have tried MANY malware and virus programs, I had norton installed on all of my machines since I bought them, and nothing can detect anything. So at this point I don't know if I am out of my mind or if there is some kind of crazy ass mega trojan living
on my laptop.
I also found a file at one point that had code for flashing my eeprom which vanished off my computer the next day. I have no idea where to go from here but to get a new computer.
Yesterday a file called TCPSVCS.EXE started making ports 7, 9, 13, 17 and 19 on both TCP and UDP. It doesn't contain any of the weird strings but it makes reference to ntdll.dll, msvcrt.dll, KERNEL32.DLL, RPCRT4.dll, USER32.DLL, and advapi32.dll.
There are also around 30 local TIME_WAIT connections starting at TCP port 51548 and then going higher which are being created by the system idle process.
So am I out of my mind and all of this is normal or has something infected my computer? I get the feeling someone has been logging in remotely but for the most part nothing bad has happened to the computer so I have no idea.
Thanks for any help!

Writing a large xml string to a file

Hi,
I get a large xml file, into a String (It might be around 8 MB also). After this, I need to write this to a file. Which java method I can use for the same.
I am getting confused by the various classes for writing a file.
I want to use the best, efficient way of doing this. Can any one please help?
public static void writeStringToFile( String fileName, String content,

          FileOutputStream fos = null;
          File file = new File (fileName);
          try {
//++ fos = new FileOutputStream( file);
      fos = new FileOutputStream( file, append );                 //++

But is there any any particular reason for using the encoding specific to xml?Yes, because that's what the XML specification says you're supposed to do. If you don't do that then you may produce malformed XML.
Will there be any perf degrade or truncation of the large string, while writing to the file, if we use,
out.write(sigUpdateString);Compared to what? You're just writing the data out to a file, the quickest way to do that is to just write the data out. The two things you should do are: (1) use a BufferedWriter (2) stop obsessing about performance.

Specify xml string in .java file?

I have a class A in a .java file where I would like to specify a string which is a xml snippet:
public class A {
public String getXmlString() {
String myXmlString = "<?xml version="1.0"?>

      <description>An in-depth look at creating applications
      with XML.</description>
   </book>
</catalog>"
}But that does not compile. I have tried to use the escape \\ charater for the qoutes and angle brackets but that does not solve the problem. How do I specify a string with xml content in a class?

Replace String within a file

i want to replace a string within a file
there is NO GUI ..
i take in mind two approaches
1) hold the file content in memory
and rewrite the file
2) write the new data to a new file.
and then rewrite the original file
any better ideas

sorry, no..
Your idea is kinda right if small file is within existance..
Small file.
Why not just use the filereader and filewriter? read the docs upon that
Large file
Why wont you create a string buffer, and parse the file chunk by chunk into that buffer one at a time. Then of course you saved the position of the character or word you wanted to apend or write, and you just write it back to that area.
