Removing special characters from a string

Hi All,
I have this in one my column in my table
ABC-DEF
ABC/DEF
ABC,DEF
ABC DEF
I want to remove -, /, comma and space so i want the result like this
ABCDEF
ABCDEF
ABCDEF
ABCDEF
How can I do this in PL/sql.
Thanks.

Use REGEXP_REPLACE:
with sample_table as (
                      select 'ABC-DEF' str from dual union all
                      select 'ABC/DEF' from dual union all
                      select 'ABC,DEF' from dual union all
                      select 'ABC DEF' from dual
-- end of on-the-fly sample table
select str,
        regexp_replace(str,'[-/, ]') new_str
from sample_table
STR     NEW_STR
ABC-DEF ABCDEF
ABC/DEF ABCDEF
ABC,DEF ABCDEF
ABC DEF ABCDEF

(i don't expect it to be done, just after guidance)
my thanks in advance

OK Here you are:
protected static String removeJunk(String string)
          int i, len = string.length();
          StringBuffer dest = new StringBuffer(len);
          char c;
          for (i = (len - 1); i >= 0; i--)
               c = string.charAt(i);
               if (Character.isLetterOrDigit(c))
                    dest.append(c);

Sql to remove special characters from my search

Hi everyone. I'm very new to sql and have hit another road block. I am doing a query on my database in oracle sql developer. I want to search manufacturer numbers but sometimes they were entered with dashes ( 999-99-9999) and other times not (999999999) is it possible to apply a function to overlook the dash in both my query numbers and in the database mfr_nbr column?
any help would be appreciated.

ok, I have built a nesting string of replaces to remove all of my special characters and it worked perfectly but now I am not sure where to place the nest later in the string to remove it from my search of mfr numbers. The reason I need to do it again is because I want to remove the characters so I am searching in terms of " apples to apples" so to speak. here is my string so far. I still need to add the part where I put in my search for the manuf_item_nbr. my question is where do I need to place the nested replace's to remove it from my numbers I'm going to search?

How can I remove special characters from spreadsheet filename?

Hi
Having a spreadsheet filename coded (on the Report Attributes page) as &VARIABLE..csv works fine unless the VARIABLE contains special characters such as space, lt, gt and so on.
In the case of space, it is replaced by %20 in the generated filename. Is it possible convert the %20s to underscores (or remove them)?
thanks
Trevor

Trevor,
I would use a computation on that page to alter the value of variable, perhaps a SQL Expression such as:
replace (:VARIABLE, ' ', '_')Alternatively, look at the process that puts the value into VARIABLE in the first place and ensure no spaces >, etc are assigned.

Removing unwanted characters from imported string

Hello,
I have a tab-delimited .txt file which I have to import into Indesign for further processing.
The file is composed by a 3 columns header row at the beginning (Code, Description, price) followed by a series of 3 columns data rows.
The problem is that sometimes, depending on the way the txt/csv file has been created, may include unwanted characters (such as spaces, double spaces, etc.).
Is there a way to "clean" the imported strings from these unwanted characters?
This is my starting code:
function processImportedTxt(){
 //Open .csv file
 var csvFile = File.openDialog("Open file .csv","tab-delimited(*.csv):*.csv;");
 datafile = new File(csvFile);
 if (datafile.exists){
 datafile.open('r');
 var csvData = new Array();
 while(!datafile.eof){//read every row till the end of file
 csvData.push(datafile.readln());
 datafile.close();
 for(a=1; a<csvData.length; a++){
 var myRowData = csvData[a];//row of data
 var mySplitData = myRowData.toString().split("\t");//divide columns
 var myRowCode = mySplitData[0];
 var myRowDesc = mySplitData[1];
 var myRowPrice = mySplitData[2];
 // Here goes code for cleaning strings from unwanted characters
processImportedTxt();
Any help would be much appreciated
Thanks in advance

Hi,
If you want to safe 1-space occurences just a small correction:
i.e.:
var myRowCode = mySplitData[0].replace(/\s\s+/g,'');

Removing special characters

Hi,
I have to remove special characters from string and replace it with space.
Kindly help its urgent.
Thanks

Hi,
You Can use Overlay command for this.
Syntax
OVERLAY text1 WITH text2 [ONLY pattern].
Effect
Characters in the text1 variable are replaced by characters in the text2 data object which are there in the same location. If the ONLY addition is not specified, all blank characters in text1 are replaced. If the ONLY addition is specified, all characters are replaced that occur in the pattern data object, and upper and lowercase is taken into consideration. If the lengths of text1 and text2 are different, text1 is processed using the shorter length only.
CONSTANTS initial_time TYPE t VALUE IS INITIAL.
DATA: time TYPE t,
text(4) TYPE c.
text = '12'.
time = text.
write : time.
Thanks,

Removing non english characters from my string input source

Guys,
I have problem where I need to remove all non english (Latin) characters from a string, what should be the right API to do this?
One I'm using right now is:
s.replaceAll("[^\\x00-\\x7F]", "");//s is a string having chinese characters.
I'm looking for a standard Solution for such problems, where we deal with multiple lingual characters.
TIA
Nitin

What's the best way to go about it?Oh, I see!
Well, the problem here is that Strings don't have any information on the language. What you can get out of a String (provided you have the necessary data from the Unicode standard) is the script that is used.
A script can be used for multiple languages (for example English and German use mostly the same script, even if there are a few characters that are only used in German).
A language can use multiple scripts (for example Japanese uses Kanji, Hiragana and Katakana).
And if I remember correctly, then Japanese and Chinese texts share some characters on the Unicode plane (I might be wrong, 'though, since I speak/write neither of those languages).
These two facts make these kinds of detections hard to do. In some cases they are easy (separating latin-script texts from anything else) in others it may be much tougher or even impossible (Chinese/Japanese).

Removing non-alpha-numeric characters from a string

How can I remove all non-alpha-numeric characters from a string? (i.e. only alpha-numerics should remain in the string).

Or even without a loop ?
Extract from the help for the Search and Replace String function :
Right-click the Search and Replace String function and select Regular Expression from the shortcut menu to configure the function for advanced regular expression searches and partial match substitution in the replacement string.
Extract from the for the advanced search options :
[a-zA-Z0-9] matches any lowercase or uppercase letter or any digit. You also can use a character class to match any character not in a given set by adding a caret (^) to the beginning of the class. For example [^a-zA-Z0-9] matches any character that is not a lowercase or uppercase letter and also not a digit.

Removing characters from a String (concats, substrings, etc)

This has got me pretty stumped.
I'm creating a class which takes in a string and then returns the string without vowels and without even numbers. Vowels and even characters are considered "invalid." As an example:
Input: "hello 123"
Output: "hll 13"
The output is the "valid" form of the string.
Within my class, I have various methods set up, one of which determines if a particular character is "valid" or not, and it is working fine. My problem is that I can't figure out how to essentially "erase" the invalid characters from the string. I have been trying to work with substrings and the concat method, but I can't seem to get it to do what I want. I either get an OutOfBoundsException throw, or I get a cut-up string that just isn't quite right. One time I got the method to work with "hello" (it returned "hll") but when I modified the string the method stopped working again.
Here's what I have at the moment. It doesn't work properly for all strings, but it should give you an idea of where i'm going with it.
public String getValidString(){
 String valid = str;
 int start = 0;
 for(int i=0; i<=valid.length()-1; i++){
 if(isValid(valid.charAt(i))==false){
 String sub1 = valid.substring(start, i);
 while(isValid(valid.charAt(i))==false)
 i++;
 start=i;
 String sub2 = valid.substring(i, valid.length()-1);
 valid = sub1.concat(sub2);
 return valid;
 }So does anybody have any advice for me or know how I can get this to work?
Thanks a lot.

Thansk for the suggestions so far, but i'm not sure how to implement some of them into my program. I probably wasn't specific enough about what all I have.
I have two classes. One is NoVowelNoEven which contains the code for handling the string. The other is simply a test class, which has my main() method, used for running the program.
Here's my class and what's involved:
public class NoVowelNoEven {
//data fields
 private String str;
//constructors
 NoVowelNoEven(){
 str="hello";
 NoVowelNoEven(String string){
 str=string;
//methods
 public String getOriginal(){
 return str;
 public String getValidString(){
 String valid = str;
 int start = 0;
 for(int i=0; i<=valid.length()-1; i++){
 if(isValid(valid.charAt(i))==false){
 String sub1 = valid.substring(start, i);
 while(isValid(valid.charAt(i))==false)
 i++;
 start=i;
 String sub2 = valid.substring(i, valid.length()-1);
 valid = sub1.concat(sub2);
 return valid;
 public static int countValidChar(String string){
 int valid=string.length();
 for(int i=0; i<=string.length()-1; i++){
 if(isNumber(string.charAt(i))==false){
 if((upperVowel(string.charAt(i))==true)||lowerVowel(string.charAt(i))){
 valid--;}
 else if(even(string.charAt(i))==true)
 valid--;
 return valid;
 private static boolean even(char num){
 boolean even=false;
 int test=(int)num-48;
 if(test%2==0)
 even=true;
 return even;
 private static boolean isNumber(char chara){
 boolean number=false;
 for(int i=0; i<=9; i++){
 if((int)chara-48==i){
 number=true;
 return number;
 private static boolean isValid(char chara){
 boolean valid=true;
 if(isNumber(chara)==true){
 if(even(chara)==true)
 valid=false;
 if((upperVowel(chara)==true)||(lowerVowel(chara)==true))
 valid=false;
 return valid;
}So in my test class i'd have something like this:
public class test {
public static void main(String[] args){
 NoVowelNoEven test1 = new NoVowelNoEven();
 NoVowelNoEven test2 = new NoVowelNoEven("hello 123");
 System.out.println(test1.getOriginal());
 //This prints hello (default constructor string is "hello")
 System.out.println(test1.countValidChar(test1.getOriginal()));
 //This prints 3
 System.out.println(test1.getValidString());
 //This SHOULD print hll
}

How to search special characters in a string

Hi all,
I want to search special characters in all string columns and all rows in the table.
The table has about 5 string columns and about 5.000.000 rows. For each row and column, I have to search entries, which included special characters like ", !, ? or something else (f.ex. "Mama?Mia" or "!!!Hotel out of order!!!"). The problem, the character could stand at each position in the string.
What's the best and most performance possibility to search such entries?? Is it possibility only by SQL; is there a special function for this?? Or must I use PL/SQL.
Thanks for helping
Dana

RegExp for excluding special characters in a string.

Hi All,
Im using Flex RegExpValidator. Can anyone suggest me the correct expression to validate this condition?....
I have tried this expression :----- /^[^///\/</>/?/*&]+$/...But in this it is also negating the alphabets.Also I have tried with opposite condition that in the String we should have alphabets and the expression is:-- ([a-z]|[A-Z]|[0-9]|[ ]|[-]|[_])*..... Please can anyone help me on this.
Thanks in advanced to all.

Remove HTML tags from a string

I have a string that contains a couple of HTML or XHTML tag, for example
lv_my_string = 'Hello World!'.
For a special use case, I want to remove all HTML from that string and process only the plain text
lv_my_new_string = 'Hello World!'.
Is there any method, function module, XSLT or anything else for that already?
