"abc&apos&s def&apos&s are alphabets" .
Kindly let me know how this requirement can be met.

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.

I need to append a string to another string

I'm working with some inherited code, I'm a Colf Fusion
novice myself, and I'm trying to make this order form display the
correct data. The problem is a lot of data in the database is
missing. Description in the QStockDB query can contain a lot of
stuff. For our full color work the text "4/0", "4/BLACK", and "4/4"
are consistent so I'm changing the newitem (I know, not very
descriptive but it's not my code) to CMYK Printing.
<cfif #QStockDB.description# contains "4/0"><cfset
newitem = "CMYK Printing"></cfif>
<cfif #QStockDB.description# contains
"4/4/BLACK"><cfset newitem = "CMYK Printing"></cfif>
<cfif #QStockDB.description# contains "4/4"><cfset
newitem = "CMYK Printing"></cfif>
I want to then go back through description and compare it
more to add more description. For instance with this:
<cfif #QStockDB.description# contains "12 pt"><cfset
newitem = newitem + " - BC"></cfif>
I know that the job is a business card. So I want to append
the newitem variable with " - BC". Likewise:
<cfif #QStockDB.description# contains
"catalog"><cfset newitem = newitem + " - Catalog
Sheets"></cfif>
displays CMYK Printing - Catalog Sheets. Or, it should... or,
more precisely, I want it to. :)
How do I append a string to another string?

+ is the addiion operator and works with numbers. Because
your string is a ...well, string... you need to use an ampersand.
Thus, instead of:
<cfif #QStockDB.description# contains
"catalog"><cfset newitem = newitem + " - Catalog
Sheets"></cfif>
Use...
<cfif #QStockDB.description# contains
"catalog"><cfset newitem = newitem & " - Catalog
Sheets"></cfif>
<cfoutput>#newitem#</cfoutput>
At least I think that will work - haven't tested it
though.

How can I substitute a string with another string in a file

I have a file. I have a substitute a keyword with another string in all the occurences of a file. How can I do this?

I'm gonna give you the benifit of the doubt and assume you didn't mean to double post your question.
As to substitute a keyword with a string one way is to read in the file and run it through a StreamTokenizer class to break it into words. Pull one word at a time, check it, and stick it into a StringBuffer. Once your done with the file overwrite it with what is in the StringBuffer.
Another way might be to use the RandomAccessFile class, but I'm not really familiar with that because I hardly ever use it.

Find occurences of a string inside another string

How can I loop through String text for occurences of String lineSeparator, and replace each occurence with String lineShift?
String lineSeparator = "<line_separator/>";
String lineShift = "\n";
String text = "This<line_separator/>is<line_separator/>a<line_separator/>test<line_separator/>";Do I have to use Patterns or something?

String lineSeparator = "<line_separator/>";
String lineShift = "\n";
String text = "This<line_separator/>is<line_separator/>a<line_separator/>test<line_separator/>";
String modified = text.replaceAll(lineSeparator, lineShift);
System.out.println(modified);

Check the API documentation for this method:
"int indexOf(String str)
Returns the index within this string of the first occurrence of the specified substring."

Take and delete a String from another String

I have original input string= 111100001111
I need to Take for example the least 4 bits .... Output= 1111
and to be removed from the original input string so the original input string= 11110000
I am trying to make a generic one but the point is that I can not delete subset that I take from the original input String.
How can I take and delete from a string in the same time?

Replaces all occurnces of one String with another String in a given source

Hi all I had found that there is a lot of interest int this topic. there is a little piece of code that I wrote for myself recently, so I fgigured that it might be helpful for some...
This method will scan through a string "source", find all of the occurances of a String "before" and replace them with the "after".
Enjoy :-)
public static String replace(String source, String before, String after)
StringBuffer sb = new StringBuffer(source);
int startpos = source.indexOf(before);
int endpos = startpos + before.length();
int i = startpos;
while( i > -1 )
     if( startpos > -1 && endpos <= source.length() )
     source = sb.replace(startpos, endpos, after).toString();
     int lastReplace = source.lastIndexOf(after) + after.length();
     if(lastReplace <= source.length())
          startpos = source.substring(lastReplace, source.length() ).indexOf(before);
               endpos = startpos + before.length();
               i = startpos;
     else
          i = source.length();
     else
          i = -1;
return source;

How to replace part of a String with another String :s ?

Got a String
" Team_1/Team_2/Team_3/ "
And I want to be able to rename part of the string (they are seperated by '/'), for example I want to rename "Team_3" to "Team C", and "Team_1" to "Team A" while retaining the '/' character how would I do this?
I have tried using String.replace(oldValue, newValue); but this doesnt work, any ideas?

What do you mean that it doesn't work? You do know that the method returns the modified string? The actual string that you invoke the method on is not altered.

Extracting string from another string

Hi,
I have a problem that I am having difficulty solving, if anyone has any bright ideas it would be a great help.
I have a description field in one of my tables and the description would read something like
my website can be found at www.mywebsite.com, and it is great
I want to be able to extract the web address from this sentance, so the result would be
www.mywebsite.com
I can do this specific for one sentance but I can't find a way to do it for many different sentances.
cheers in advance

r u expecting this..?
select substr('my web site is www.abcd.com and u can...',instr('my web site is www.abcd.com and u can...','www.',1),instr(substr('my web site is www.abcd.com and u can...',instr('my web site is www.abcd.com and u can...','www.',1)),' ',1)) from dual;
