Reg: Replacement of second occurance of character in string

Hi,
Consider one string1 = 'ABCDAE' OR string2 = 'SHEETAL'.
I want to replace the second occurance of A in above string1.and second occurance of E in above string2 with any differnt character.
I tried with offset calculation , length , replace , split stmts.
but always first occurance is getting replace.
Please provide your ideas.
Regards,
Shital

Hi,
Try this.
data: string1 type char10 value 'ABCDAE',
        len     type i.
write: / string1.
search string1 for 'A'.
if sy-subrc = 0.
    add 1 to sy-fdpos.
    len = strlen( string1 ) - sy-fdpos.
    replace 'A' in string1+sy-fdpos(len) with '!'.
    write: / string1.
endif.

Search and replace, everey second character?

I'm making a VI that is communicating with an external device through a protocol built up of frames. I have made a couple of subVIs that put these frames together as hexadecimal strings that are then converted into numbers and passed on to the device. The protocol uses an escape character in order to avoid sending an BOF or EOF constant at the wrong time. I've made a subVI that is supposed to do this using the Serch and Replace function. At first it seems rather elegant, but it has a fatal flaw, if one of the characters it is supposed to hide is written across the edge of a byte, it will still be replaced.
Example:
11 01 00 EC 0D EA 05 08
is replaced by
11 01 00 E7 DE 0D EA 05 08
C0, C1, 7D are the characters to be replaced, 7D is the escape character.
Now I wonder, is it possible to make the search and replace function search only every second character in a string?
Solved!

Error occurred during character conversion in SXMB_MONI

Hello Experts,
Good Day!
I would like to seek your help here. When i used tcode SXMB_MONI to search for messages i get this error : Error occurred during character conversion.
So far no problem with the program. Its work for all other dates. Just for one particular day and specific time period, im geting this error.
Does anyone know what is this error means? Please reply..
Thanks for your help.
Looking forward for ur replies..

Hi Presheela,
Basically this problem occurs when ur payload contains any special characters like '&' ,'>'...etc .So you have to take care of how to deal with these characters in XI.
Refer the following documentation:
How to Work with Character Encodings in Process Integration

Replacing all occurrences of characters in a string with one new character?

Hi there,
I'm looking for a way that I could replace all occurrences of a set of specific characters with just one new character for each occurrence.
For example if I have a string which is "word1...word2.......word3....word4............word5" how would I be able to replace this with just one character such as ":" for each set of "." so that it would essentially appear like this "word1:word2:word3:word4:word5"
If I just use replace(".", ":") I am left with "word1:::word2:::::::word4::::word5::::::::::::"
So therefore I'm guessing this would require the use of replaceAll() maybe? but I'm not really very familiar with how regular expressions work and how this would be accomplished using them.
Any help would be greatly appreciated :) Thanks.

Yes, but "." means any character, so ".\+" means "any character repeated more than once". If you just mean a full stop ("period" for you Americans :p) you should use "\.+" as your regular expression, but remember that for Java you need a '\' escape to recognise '\' as '\', so in code you'd actually type your regex as:
"\\.+"Here's an example of one way to do it:
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class Test {
    public static void main(String[] args) {
       String string = "example1.......example2...example3.....example4";
     Pattern pattern = Pattern.compile("\\.+");
     Matcher stringMatcher = pattern.matcher(string);
     string = stringMatcher.replaceAll(":");
     System.out.println(string);

SMQ2 (Inbound Queue) : Error occurred during character conversion

Hi,
In SMQ2 an Inbound Queue has failed with status text "Error occurred during character conversion". The XML message inside this queue is in waiting status with status text " Scheduled for Outbound Processing" .
Even after cancelling this message from SXMB_MONI, and reposting the PO, still again the queue and the XML message inside the queue are in same status.
As this is in XI production system, requesting to provide some suggestion ASAP.
Thanks,
Mateen.

The queue status is still sysfail. There is only 1 message waiting in the queue.
I think that the queue might be locked for some reason and after unlocking the queue and restarting the message, the message will get processed successfully.
But before working on this I want to make sure that the queue is locked.
Do you or anyone else know how and from where can I check whether the queue is locked or unlocked?
Regards,
Mateen.

Replace any occurence of a character in a varchar2 column

What would be the best way to replace any occurence of a character in a column (varchar2) of a table?
Lets say we want to replace any occurence of the character ~ by the character & in the column c1 of the table t.
Is it possible in pure SQL?
I did it in PL/SQL in a while loop but I am pretty sure there is a way to do that in a single SQL statement. Am I right on wrong?
Thanks
Best regards,
Carl

The Ampersand has a special meaning in SQL to mark a variable.
That's why you need to set 'scan off' or 'define off' or

Java.lang.String: How can we replace the list of characters in a String?

String s = "abc$d!efg:i";
s = s.replace('=', ' ');
s = s.replace(':', ' ');
s = s.replace('$', ' ');
s = s.replace('!', ' ');
I want to check a list of illegal characters(Ex: $ = : ! ) present in the String 's' and replace all the occurance with empty space ' '
I feel difficult to follow the above code style.. Because, If list of illegal characters increased, need to add the code again to check & replace the respective illegal character.
Can we refactor the above code with any other simple way?
Is there any other way to use Map/Set in this above example?

RTFM
http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html
That document is almost perfectly useless for someone
who is just starting to learn regexes. What they
need is a good tutorial, and the best one I know of
for Java programmers is the one at
this site. When you're ready to move on from
introductory tutorials, get the latest edition of
Mastering Regular Expressions, by Jeffrey Friedl.Dear Uncle,
maybe you want to read that document first before judging its usefulness. And just in case you can't be bothered, the following is an exact quote, which accidently happens to clearly explain the op's question on the usage of \\[\\] in sabre's regex:
Backslashes, escapes, and quoting
The backslash character ('\') serves to introduce escaped constructs, as defined in the table above, as well as to quote characters that otherwise would be interpreted as unescaped constructs. Thus the expression \\ matches a single backslash and \{ matches a left brace.
It is an error to use a backslash prior to any alphabetic character that does not denote an escaped construct; these are reserved for future extensions to the regular-expression language. A backslash may be used prior to a non-alphabetic character regardless of whether that character is part of an unescaped construct.
Backslashes within string literals in Java source code are interpreted as required by the Java Language Specification as either Unicode escapes or other character escapes. It is therefore necessary to double backslashes in string literals that represent regular expressions to protect them from interpretation by the Java bytecode compiler. The string literal "\b", for example, matches a single backspace character when interpreted as a regular expression, while "\\b" matches a word boundary. The string literal "$hello$" is illegal and leads to a compile-time error; in order to match the string (hello) the string literal "\$hello\$" must be used.

Since you are using the termination character, you should not use the Bytes At Port property node. Just set the number of bytes to read for the VISA Read to something really high (larger than what you expect in a single transmission). The VISA Read will stop reading once the termination character is reached.
Now, what is the format of the data coming from the instrument? I see you are converting an ASCII Hex string into a number while trying to also turn it into a double. That is likely why you are getting your error.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Replace all occurrences of ENTER in a string

Hi,
I have a string which contains line breaks:
'<HTML><HEAD>
</HEAD>
<BODY>'
and it is shown to me in the debugger as:
'<HTML><HEAD>#</HEAD>#<BODY>'
Now I want to replace all line breaks in the string,
but
replace all occurrences of `#` in text with ' '.
doesn't work.
So if you have an idea how to replace the # symbol for Enter in a string please tell me ;).

Hi,
Pls use
replace all occurences of '#' in text with cl_abap_char_utilities=>newline.

My client is using Java and they are saying that they are using this key for their AES256 Encryption and working fine. I have asked them to provide me 32 bytes key as in Oracle 256bit is 32 character string.
Let me see what they have to say.
I was wondering why Java has 64 bytes for 256 AES encryption when Oracle need only 32 bytes for same encryption.I am not sure I completely understand how those built-in packages work but the doc example produces the raw key that is same in length (in terms of number of characters) as the one you are using.
Yet your UTL_I18N packaged function fails for your key but works for the documentation example.
