How to remove certain character from a string?

Follows the table:
CT_TRABALH
400rj101
400rj102
400rj103
400rj104
400rj105
400rj106
400rj107
400rj108
400rj109
400rj1010
400rj1011
I woulld like to make the following with its values. For example the value 400rj1010
I would like to remove its last character (400rj101) and then relace the last zero for the last number(400rj111) by query. Is there any way I can achieve this?

I would write something a little more generic :
SCOTT@demo102> with tbl as
2      (select '400rj101' as CT_TRABALH from dual union all
3       select '400rj102' from dual union all

17         case when substr(CT_TRABALH,-1,1) = '0'

How to remove HTML tags from a String ?

Hello,
How can I remove all HTML Tags from a String ?
Would you please to give me a simple example ?
Best regards,
Eric

Here's some code I cooked up. I have created an object that processes code so that it can be incorporated directly into a project. There is some redundancy so that the it can be used in more than one way. Depending on your situation you might have to make the condition statement a little more sophisticated to catch stray ">" tags.
I have also included a Tester application.
//This removes Html tags from a String either by submitting the String during construction and then
// calling getProcessedString() or
// by simply calling " stringwithoutTags=removeHtmlTags(stringWithTagsSubmission); "
//Note: This code assumes that all"<" tags are accompanied by a ">" tag in the proper order.
public class HtmlTagRemover
     private String stringSubmission,processedString,stringBeingProcessed;
     private int indexOfTagStart,indexOfTagEnd;
     public HtmlTagRemover()
     public HtmlTagRemover(String s)
          removeHtmlTags(s);
     public String removeHtmlTags(String s)
          stringSubmission=s;
          stringBeingProcessed=stringSubmission;
          removeNextTag();
          return processedString;
     private void removeNextTag()
          checkForNextTag();
          while((!(indexOfTagStart==-1||indexOfTagEnd==-1))&<indexOfTagEnd)
               removeTag();
               checkForNextTag();
          processedString=stringBeingProcessed;
     private void checkForNextTag()
          indexOfTagStart=stringBeingProcessed.indexOf("<");
          indexOfTagEnd=stringBeingProcessed.indexOf(">");
     private void removeTag()
          StringBuffer sb=new StringBuffer("");
          sb.append(stringBeingProcessed);
          sb.delete(indexOfTagStart,indexOfTagEnd+1);
          stringBeingProcessed=sb.toString();
     public String getProcessedString()
          return processedString;
     public String getLastStringSubmission()
          return stringSubmission;
public class HtmlRemovalTester
     static void main(String[] args)
          String output;
          HtmlTagRemover h=new HtmlTagRemover();
          output="The processed String: "+h.removeHtmlTags("<Html tag>This is a test<another Html tag> string<yet another Html tag>.");
          output=output+"\n"+" The original string:"+h.getLastStringSubmission();
          System.out.print(output);

How to get specific character from a string

I have a value such as: 0-5 or 123-30. This is a combination
from 2 different IDs.
All I need is to get the number on the right (5 from 0-5 OR
30 from 123), any number on the right of the "-" character not
including
the "-"
I'm not sure what ColdFusion function can I use safely.
I said safely since all I can find is either Left or Right
functions. With these 2 functions, I need to specify the number of
character to extract while in my case the application is growing so
the ID may currently be only 1 digit each (0-5) but later it may
grow longer (123-5677).
If anyone know the function, please help me. Thank you!

Something like this?
Mid(string, Find("-",string)+1 ,
Len(string)-Find("-",string))
Since
Mid(string, start, count)
and
Len(string or binary object)
and
Find(substring, string [, start ])
Or perhaps ....
ListLast(string, "-")
since
ListLast(list [, delimiters ])

How to remove empty char from a string

Hi,
In my code I should get numeric int numbers and convert them to 1 and 0 , concatenate thm to make an string ( 8 chars) . the problem I have is the empty chars as result of conversion from number to string
so lets say pxiAnaIn=1 dutVdd=2 and dutOut=5 so then the output should be 10110001 but now the output is 10110 1 . could you please let me know how can I fix this problem

You could make your life a little easier and only use 1 format string. Use "%03b%02b%03b" for the format string. You can then expand the format string to allow multiple inputs. You will do the job of 4 functions with just 1.
"%3b" just says to give 3 spaces for the binary number. But any preceding 0s will be turned into spaces. Adding the 0 in there tells the format string to prepend 0s instead of using spaces.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

How to remove a character in a file??

I'm not getting how to remove a character from a file.Could anyone post a method to do this?Any help would be appreciable.

Ohhh... and one more thing... unless you're really unlucky, a few "extranious trailing nulls" won't make a jot of difference to the size of the file on disk, each each file "fills" whole blocks anyway, which is 1K (I think) on both fister and *nix... unless of course we're talking "lots" of trailing-nulls, or lots-and-lots of files.

Getting one character at a certain position from a string array

Hi, i'm new at learning java, but have strong experience at C++ and asm. How would i get one character at a certain positon from a string array.
for example:
String Phrases[] = {"To be or not to be, that is the question","The Simpsons","The Mole","Terminator three rise of the machines","The matrix"};
that is my string array above.
lets say i wanted to get the first character from the first element of the array which is "T", how would i get this

ok well that didn't work, but i found getChars function can do what i want. One problem, how do i check the contents of char array defined as char Inchar[];

How to change a certain character in a string?

hi,
how can i change a certain character in a string. Lets say i have a string s="0000" and i want to change the last character (s.charAt(3)) to be a 1. how would i go about doing so?

i did this
num.charAt(lspace) = s.charAt(i+1);and am getting an errorThat's because you can't do that. You should go for one of the alternatives mentioned above.

Strip the first character from a string

i am trying to strip the leftmost character from a string
using the following:
<cfset Charges.DTL_CHG_AMT_EDIT =
#Right(Charges.DTL_CHG_AMT_EDIT,Len(Charges.DTL_CHG_AMT_EDIT)-1)#>
i keep getting the following error:
Parameter 2 of function Right which is now -1 must be a
positive integer

> RemoveChars() much easier than Right()? How so?
Semantically, if the object of the exercise is to *REMOVE
CHARacters from a
string* (which it is, in this case), it is simply better
coding to use
removeChars() rather than right(). That, and it's one less
function call
(the RIGHT() solution also requires a call to LEN() for it to
work).
So removeChars() is "easier" because it reflects the intent
of the exercise
directly, is simpler logic, is easier to read, and - I can't
be arsed
counting keystrokes - is probably less typing.
That'd be how.

How to remove a node from nlb at runtime?

hello,
i need to temporally exclude a node from an nlb.
May happen that a server is up and working but the web application i'm balancing is out of sinch with the same application in the others nodes.
Eg. some static variables are not the same of the same static variables of other nodes, because of a timeout, a write error and so on but the server is still working.
in this case i need to stop the server from nlb because the information in the web application is not in sinch with other nodes.
I need to prevent users from being serverd from this out to date server, untill it will became updated, but i need to do this programmatically
how can i do it?

either this way we can do this
1)
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
<b> factory.setIgnoringElementContentWhitespace(true); </b>
DocumentBuilder db = factory.newDocumentBuilder();
or
2)
java.io.StringWriter sw = new java.io.StringWriter();
StreamResult sr = new StreamResult(sw);
t.transform(new DOMSource(doc), sr);
String xml1 = sw.toString().trim();
<b> xml1=xml1.replaceAll("\\s",""); </b>
