Replacing the letters in a string

I have an odd set of fields for properties for my client.
Some have multiple
letters which correspond to a code table. How can I loop
through the string
and replace the letters with words
For example
A = central air
B = ceiling fan
C = A/C Unit
If the field looks like 'ABC', it would be outputted to the
page as 'central
air ceiling fan A/C Unit'

You don't say how many unique letters you have, but I presume
it is 26 or less. If that's the case, you could index an array that
has been initialized with the words. See concept code below. It
assumes only upper case letters.

Replacing the \ character in a string

I'm having trouble replacing a backslash in a string. I use .indexOf() to find the character, but I have to use an escape character and write .index("\\"), but it doesn't work - it returns -1.
Also, replace() doesn't work - gives me an java.util.regex.PatternSyntaxException. Any ideas?
thx

The escape is for the compiler, I think, and then you need to escape the backslash.
Try "\\\\".

I want to Replace all the Existence of the word - "Test" in a string with "Test1" whereever a space exits before the word Test and someother alphabet after "Test" i.e. Test will be replaced with Test1 if a word starts with Test and contains more alphabets also. For example - TestName should be replaced with Test1Name while MyTest should not be updated to MyTest1.
I have tried to use below query which uses oracle regular expressions -
SELECT REGEXP_REPLACE('MYCOMPANY TEST TESTGEET INDIA PVT LTD TEST','\s(TEST)\w',' TEST1') FROM DUAL
Output -
"MYCOMPANY TEST *TEST1EET* INDIA PVT LTD TEST"
Here, it has also replaced the G also from TESTGEET and resulted in TEST1EET while i want TEST1GEET.
Can someone please suggest how can i do this..... may b m doing some silly mistake but sorry m a newbie to regular expression...
Thanks in advance..

Acrobat is Replacing Certain Letters with Dots

Hi. I am using Acrobat 9 to produce PDF documents from InDesign CS4 in Windows XP.
Of late, when I make a PDF from my ID book file, it is replacing the letters "fi" or "fl" (as in file, flow, specification, etc.) with a dot. I cannot figure out why this is happening. It only started happening recently. I notice that this anomaly doesn't occur if the "F" is capitalized (as in Figure).
What can be done? Any help appreciated.
- Shady

Thanks everyone! Wow, I cannot believe I did not know about File > Export. I was taught years ago to use Print > Adobe PDF. Whatever, the export function cleared the problem up...still curious as to how the dot problem could have happened all of a sudden when it didn't for months before. Maybe a Windows *.dll file from an upgrade; who knows?
All the Best,

Open the file as a RandomAccessFile. Check its length. Declare a byte array as big as its length and do a single read to get the file into RAM.
Is this a simple text file (bytes)? No problem. If it's really 16-bit chars, use java.nio to first wrap the byte array as a ByteBuffer and then view the ByteBuffer as a CharBuffer.
Then you're ready for search/replace. Do it as you would in any other language. Be sure to use System.arraycopy() to shove your bytes right (replace bigger than search) or left (replace smaller than search).
When done, a single write() to the RandomAccessFile will put it all back. As you search/replace, keep track of size. If the final file is smaller than the original, use a setLength() to the new size to avoid extraneous data at the end.

Problem in replacing the String in a Fille.

I need to replace the String in the text file, am able to do it partially.
I mean, am able to replace it. But there are some discrepancies if the replacement string is of "less" or "more" in length than the existing one.
I solved it for the replacement string of less size, but am unable to do it for the string of more size.. :(
The problem am facing is "when the replacement string is larger than the existing one, then the other subsequent line in the file gets overwritten".
I have used RandomAccessFile class for reading and writing the same file.
fpointer1 = randomFile.getFilePointer() - strLine.length() - 2;
strLine1 = strLine;
int sInd = strLine1.indexOf('\'');
int eInd = strLine1.indexOf(';');
String oldStr = strLine1.substring(sInd + 1, eInd - 1);
strLine1 = StringUtils.replace(strLine1, oldStr, newStr);
if (oldStr.length() < newStr.length()) {
int diff = (newStr.length() - oldStr.length()) + 1;
randomFile.writeBytes("\r\n");
for (int i = 0; i < diff; i++) {
randomFile.writeBytes(" ");
randomFile.seek(fpointer1);
randomFile.writeBytes(strLine1);
} else if (oldStr.length() > newStr.length()) {
randomFile.seek(fpointer1);
randomFile.writeBytes(strLine1);
int diff = (oldStr.length() - newStr.length()) + 1;
for (int i = 0; i < diff - 1; i++) {
randomFile.writeBytes(" ");
randomFile.writeBytes("\r\n");
break;
}Can u pls help me in resolving this issue???...

As u said the overwriting causes the problem, but i managed to resolve for the string of less size.I assume you did this with some padding? That's not exactly a clean solution.
So thats why am seeking to manage the larger size string to replace without overwriting the sub sequent lines.
Can you help me in suggesting whether it can be resolved using the getFilePointer() and seek() methods??...No you can't.
Whether you shorten or lengthen the position where you modify the file, you need to move the remaining bytes back or forward, depending which is the case.
You managed to solve the first case by printing out padding, so you don't need to move the bytes back, but you can't solve the other case like this. You can lengthen the file and move the remaining bytes forward, but I probably wouldn't bother since a simple Reader-based approach is a lot better and easier to get right.

Replace the connection string in Excel MDS file

I had MDS solution from one SQL Server 2012 to another - SQL Server 2014. I have configured Excel file with connection to MDS. How can I safely to replace the connection string in my Excel MDS file and the tables is not broken?
from Moscow with money

Hi,
Excel is just used to manage data and create new entities and attributes. Why not first publish and close your excel before MDS upgraded to 2014? After the upgrade, reconnect new solution in your excel.

Replacing the same value in a string with varying values

If I have a string:
"%s is the %s I am referring to"
and - I want to replace the %s occurrences with DIFFERENT values... what's the best way to do this.
I was thinking parsing it into seperate strings using substr and instr but, I'm not sure if that's overkill or not.
Replace is ideal but - it replaces every occurrence so - you can state just replace the first occurrence with one value and the second with another (i.e. if the desired result after replacing the above string was supposed to be "This is the string I am referring to"
Any help is appreciated.
Thanks

Explain how you get those results from that data.
Always say which version of Oracle you're using (e.g. 11.2.0.3.0).
See the forum FAQ {message:id=9360002}
I was thinking parsing it into seperate strings using substr and instr but, I'm not sure if that's overkill or not.Depending on your requirements, you might need to do that.
Replace is ideal but - it replaces every occurrence so - you can state just replace the first occurrence with one value and the second with another (i.e. if the desired result after replacing the above string was supposed to be "This is the string I am referring to"As you said, REPLACE changes all occurrences. There's no way to tell it (for example) to change only the first one.
REGEXP_REPLACE, is a lot more flexible. It does have an option for giving a specific occurrence, but you may not even need that feature. You might just want something like
REGEXP_REPLACE ( '%s is the %s I am referring to'
            , '(.*)%s(.*)%s(.*)'
            , '\1This\2string\3'
            )It all depends on your data and your requirements.
Are the new values (such as 'This' and 'string') fixed, or can they change from row to row?
Will you always have 2 (or some known number) of '%s's in the original string?
Does '%' always signal something that is to be replaced? If not, how can you tell when it does and when it doesn't?
Does 's' always come right after '%'? If not, what are the possibilites, and what do the different characters signify?

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?

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.

Replace the first character in a String with blank

String a = dgramRsp.getAddress().toString();
a = a.replace('/','');The problem with the first statement is that it returns an ip address with a '/' in front of it. Like so.../192.168.0.190
I need to get rid of the '/'. The replace won't work because it wants a character between the ' '. Thanks for your time.

I had to think about it for a sec but yes you're
right.
InetAddress a = dgramRsp.getAddress();
String b = a.getHostAddress();
substring(1) would have worked, too, but it would have been redundant (removing a previously added slash).

How to replace the char values into numeric in my string?

Hi Friends,
I would like to Replace the Charecter values with numeric value in my string.
Exp : first in my string I am having the value like this : 'ABCD1234' ( may be any char and num values ), and I want too get it by '99991234'.

Hi Sridhar,
I would like to Replace the Charecter values with numeric value in my string.
Exp : first in my string I am having the value like this : 'ABCD1234' ( may be any char and num values ), and I want too get it by '99991234'.
So, if i understand you correctly, you want to replace all characters in a string with 9 as in the above example, irrespective of position of the character, if so try with the below code.
DATA: l_str TYPE string.
l_str = 'ASKHSIUDNSBDKJSDH124312431243124saasdfsf'.
REPLACE ALL OCCURRENCES OF REGEX '\D' IN l_str WITH '9'.
IF sy-subrc EQ 0.
WRITE: l_str. "Result will be 9999999999999999912431243124312499999999
ENDIF.

How to replace the string in a file

Hi, I have a file which contains the following data
File.dat
<file>
<filenum>
W10
</filenum>
<hello>Heading </hello>
</file>
I need to replace the contents of file.dat
database sequence value (for example xx_seq.nextval)
Can some one please tell me how to search this <filenum>
W10</filenum>
and replace this with xx_seq.nextval
and write the entire contents of the file to new file
I am doing some thing like this
suppose if my database value returns 11 from the above sequence then
the output should be in file2.dat as
<file>
<filenum>
11</filenum>
<hello>Heading </hello>
</file>
declare f_in utl_file.file_type;
s_in varchar2(10000);
string1 varchar2(32000);
x number;
begin
f_in := utl_file.fopen('SAMPLEDIR','input.txt','R');
f_in1 := utl_file.fopen('SAMPLEDIR','input1.txt','W');
select xx_seq.nextval into x from dual;
loop
begin utl_file.get_line(f_in,s_in);
EXCEPTION
WHEN NO_DATA_FOUND THEN
EXIT;
string1:= string1 || s_in;
utl_file.put_line( (f_in1,s_in);
end;
end loop;
utl_file.fclose(f_in);
end;
In this case it is reading and writing as it is, but unable to replace the sequence value
Can some one please tell me how to do using replace function
Thanks

If you're able to boot, launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
Select the most recent panic log under System Diagnostic Reports. Post the contents – the text, please, not a screenshot. For privacy’s sake, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post "shutdownStall" or "hang" reports.
If you can't boot in the usual way, try a safe boot. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is slower than normal, and some things won’t work at all.
