Replace a character in a string

Hi,
I've been tearing my hair out trying to do something very simple, replace a backslash character in a string with an underscore. I've searched online and discovered the -replace parameter which you would think would work fine but no, it seems to get in a
tizzy because the character I want to replace is a backslash and I get an error: "Invalid regualr expression pattern".
Here's what I have which produces the error:
$str = 'start\end'
$str = $str -replace '\','_'
Can someone tell me how to do this? I simply want to replace a backslash with an underscore.
thanks

sod's law. I spend half an hour trying to figure this out and then as soon as I post this thread I figure it. The following works:
$str = 'start\end'
$str = $str -replace '\\','_'
$str

About me
"-replace" requires a regular expression for each argument, which is why you needed to escape your backslash with another backslash. If you use the replace() string method, you are not required to use regular expressions:
$str = $str.replace('\','_') will work exactly as you expect it to.

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..

Replace a character in a String array

I have an array of strings and am trying to replace the ' character with a space. I keep getting either a cannot be applied or cannot resolve symbol error. Can anyone help?
String arrayList = request.getParameter("field");
String newList = arrayList.replace("\'", " ");

the replace method of the String class takes two parameters and both of them are characters not strings use it like this
arrayList.replace('\'', ' ');that should fix it

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 "\\\\".

Replacing a character in a String

Hi All,
How can I replace a character ' which appears in a String into \'

There is a method in String that replaces all
occurrences of one character with anothercharacter.
It's called, hold your breath now, "replace".But tho OP wants to replace one character with two
characters :)You're right, I missed that. Well, serves me right for being sarcastic. :-)

Replace a character in the string using JavaScript

Hello,
I would like to ask for help. I have a field in the xml file, which contains a string, that is bound to a text box on the form.
What would be the syntax to replace a special character in the string with the carriage return?
Thank you.

Huh?
I didn't post my script...
It sure is no clean programming since I just took Steve's solutions and delted the ligns I didn't want (the app allert)
Though in the end I've taken the boolean out, or better replaced it with the replacement function, it repeats the replacement no matter how much "ü"'s are in there. (I needed the boolean though, since as long as it was true, the if should be executed.)
Somehow it worked... not 100% sure why, but it worked.
if (findChar(this.rawValue)) {
function findChar(str)
{ for (var i=0; i < str.length; i++)
if (str.charAt(i) == "ü")
this.rawValue = this.rawValue.replace(/ü/,"ue")

Replace a character from a string

Hi,
how can I replace a particular character from a string on a particular occurrence? Say for eg, if i wan to replace 'a' of second occurrence from 'abcabcabc', then what should i do? I guess the normal REPLACE function replaces every occurrence in a given string. So is there any other way to solve this?
Thanks!

If you are in 9i:
Then you got to split the string into based on the nth position.

Replace hex character in a string with another hex character

Hi Guys,
Heres a problem scenario, hex character 92 looks very much like hex character 27 (apostrophe).
I need to write a program that can replace all hex character 92 to hex 27 in a string.
Being a novice on the regular expressions, I would appreciate if somebody can show
the exact syntax to to perform this replacement.
Many Thanks
-Anil

I don't think you need to use regex to do this:
String s = something();
char a = 0x27;
char b = 0x92;
s.replace(a,b);
And don't forget that since Strings are immutable you need:
s = s.replace(a,b);to do anything useful.

REPLACE
Syntax Forms
Pattern-based replacement
1. REPLACE [{FIRST OCCURRENCE}|{ALL OCCURRENCES} OF]
pattern
          IN [section_of] dobj WITH new
          [IN {BYTE|CHARACTER} MODE]
          [{RESPECTING|IGNORING} CASE]
          [REPLACEMENT COUNT rcnt]
          { {[REPLACEMENT OFFSET roff]
             [REPLACEMENT LENGTH rlen]}
          | [RESULTS result_tab|result_wa] }.
Position-based replacement
2. REPLACE SECTION [OFFSET off] [LENGTH len] OF dobj WITH new
                  [IN {BYTE|CHARACTER} MODE].
Effect
This statement replaces characters or bytes of the variable dobj by characters or bytes of the data object new. Here, position-based and pattern-based replacement are possible.
When the replacement is executed, an interim result without a length limit is implicitly generated and the interim result is transferred to the data object dobj. If the length of the interim result is longer than the length of dobj, the data is cut off on the right in the case of data objects of fixed length. If the length of the interim result is shorter than the length of dobj, data objects of fixed length are filled to the right with blanks or hexadecimal zeroes. Data objects of variable length are adjusted. If data is cut off to the right when the interim result is assigned, sy-subrc is set to 2.
In the case of character string processing, the closing spaces are taken into account for data objects dobj of fixed length; they are not taken into account in the case of new.
System fields
sy-subrc Meaning
0 The specified section or subsequence was replaced by the content of new and the result is available in full in dobj.
2 The specified section or subsequence was replaced in dobj by the contents of new and the result of the replacement was cut off to the right.
4 The subsequence in sub_string was not found in dobj in the pattern-based search.
8 The data objects sub_string and new contain double-byte characters that cannot be interpreted.
Note
These forms of the statement REPLACE replace the following obsolete form:
REPLACE sub_string WITH
Syntax
REPLACE sub_string WITH new INTO dobj
        [IN {BYTE|CHARACTER} MODE]
        [LENGTH len].
Extras:
1. ... IN {BYTE|CHARACTER} MODE
2. ... LENGTH len
Effect
This statement searches through a byte string or character string dobj for the subsequence specified in sub_string and replaces the first byte or character string in dobj that matches sub_string with the contents of the data object new.
The memory areas of sub_string and new must not overlap, otherwise the result is undefined. If sub_string is an empty string, the point before the first character or byte of the search area is found and the content of new is inserted before the first character.
During character string processing, the closing blank is considered for data objects dobj, sub_string and new of type c, d, n or t.
System Fields
sy-subrc Meaning
0 The subsequence in sub_string was replaced in the target field dobj with the content of new.
4 The subsequence in sub_string could not be replaced in the target field dobj with the contents of new.
Note
This variant of the statement REPLACE will be replaced, beginning with Release 6.10, with a new variant.
Addition 1
... IN {BYTE|CHARACTER} MODE
Effect
The optional addition IN {BYTE|CHARACTER} MODE determines whether byte or character string processing will be executed. If the addition is not specified, character string processing is executed. Depending on the processing type, the data objects sub_string, new, and dobj must be byte or character type.
Addition 2
... LENGTH len
Effect
If the addition LENGTH is not specified, all the data objects involved are evaluated in their entire length. If the addition LENGTH is specified, only the first len bytes or characters of sub_string are used for the search. For len, a data object of the type i is expected.
If the length of the interim result is longer than the length of dobj, data objects of fixed length will be cut off to the right. If the length of the interim result is shorter than the length of dobj, data objects of fixed length are filled to the right with blanks or with hexadecimal 0. Data objects of variable length are adapted.
Example
After the replacements, text1 contains the complete content "I should know that you know", while text2 has the cut-off content "I should know that".
DATA:   text1      TYPE string       VALUE 'I know you know',
        text2(18) TYPE c LENGTH 18 VALUE 'I know you know',
        sub_string TYPE string       VALUE 'know',
        new        TYPE string       VALUE 'should know that'.
REPLACE sub_string WITH new INTO text1.
REPLACE sub_string WITH new INTO text2.

How to replace only the first specified character in a string and leave other occurrence of the character alone.

Hello my Friends:
I have a string that looks like this in a column:
Hello, World, Hello, Planet
I want to replace only the first occurrence so that the result looks like this:
Hello World, Hello, Planet
Working on some bad data source.
I need to replace the character regardless of it's location as long as it is the first.
I tried something like this, but I soon discovered that if the comma or character is missing the the string may get truncated or altered. If there are no characters in the string, then I want to simply leave it alone.
Here is where I am at:
DECLARE @MyValue NVARCHAR(MAX) = 'Hello, World, Hello, Planet';
SELECT MyString = STUFF('Hello, World', CHARINDEX(',', @MyValue, 0), 1, ' ');
Thanks my friends.

I have a string that looks like this in a column:
Hello, World, Hello, Planet
Why doesn't it say Hello Kitty?
Oh, sorry about that. Anyway:
SELECT MyString = CASE WHEN CHARINDEX(',', @MyValue, 0) >= 1
   THEN STUFF(MyString, CHARINDEX(',', @MyValue, 0), 1, ' ')
   ELSE MyString
   END;

Function in oracle to find number of occurances of a character in a string

hi,
is there any function in oracle to find the number of ocurrances of a character in a string ?
or is there any simple way of doing the same, rather than writting many lines of code as my program is already very complex.
Maria

Hi Maria,
I don't know of such a function in Oracle, but maybe you could use this:
length(search_string) - length(replace(search_string, character_to_be_found))
For example: select length('Hello') - length ( replace('Hello', 'l')) from dual;
Hope this is what you're looking for
