Remove unwanted chars from a string

hi friends,
mi special requirement is this:
i have a string containing:
"Jose[12] M[36]ller" and i only want to see [12][36] afterwards, so how could i remove the remaining characters ?
Thank you!

Hi Clemens,
if u only want the data enclosed in the parentheses[] along with the parentheses then this program will work fine for you. Check the same and get back to us. If u can elaborate ur reqmt then we can help in a better way.
REPORT zyh284_test2.
DATA:
w_string TYPE string VALUE 'Jose[12] M[36]ller',
w_sub_string TYPE string,
w_int TYPE i,
w_char,
w_counter TYPE i,
fl_flag.
w_int = STRLEN( w_string ).
w_counter = 0.
DO w_int TIMES.
w_char = w_string+w_counter(1).
IF w_char EQ '['.
    fl_flag = 'X'.
ENDIF.
IF fl_flag = 'X'.
    CONCATENATE w_sub_string w_char INTO w_sub_string.
ENDIF.
IF w_char EQ ']'.
    CLEAR fl_flag.
ENDIF.
w_counter = w_counter + 1.
ENDDO.
WRITE:w_sub_string.

Remove one char from a string

What is is the easiest and fastest way to delete a single character from somewhere in a string?
I have both the char and the index in the string of the char easily available, but there doesn't seem to be a String.remove(int charIndex) method which I really want. Any tips? Thanks.

"Easiest" and "fastest" are relative to what? Here's a couple of ways:String newString = oldString.substring(0, index) + oldString.substring(index+1);
String newString = (new StringBuffer(oldString)).deleteCharAt(index).toString();I'm sure there are many other ways.

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

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,'');

How do I remove unwanted updates from the App Store?

How do I remove unwanted updates from the App Store? So you understand better what I'm referring to:
I have the App Store icon in the Dock. When there's an update a red number appears on said icon. Well, I went to check on the updates and it's for 4 different applications I either no longer have or use. One of them is an update for Lion OS users. I'm still on Snow Leopard, so it doesn't even apply to me.
So there they sit... I'm not going to download the updates... so how do I get rid of them?

Hi Andy ..
no longer have or use
If there are updates available for apps you have deleted, try this.
Go to ~/Library/Caches/com.apple.appstore
Move the Cache.db and Updates files from the com.apple.appstore folder to the Trash.
Empty the Trash, restart your Mac.
For any apps you still have installed but do not use, the updates will still be available from the Updates top of the App Store window and show on the red badge on the App Store icon in the Dock.

I need urgent help to remove unwanted adware from my iMac. Help!

I need urgent help to remove unwanted adware from my iMac. I have somehow got green underline in text ads, pop up ads that come in from the sides of the screen and ads that pop up selling similar products all over the page wherever I go. Its getting worse and I have researched and researched to no avail. I am really hestitant to download any software to remove whatever it is that is causing this problem. I have removed and reinstalled chrome. I have cleared Chrome and Safari cookies. Checked extensions, there are none to remove. I need to find an answer on how to get rid of these ads. Help please!

You installed the "DownLite" trojan, perhaps under a different name. Remove it as follows.
Back up all data.
Triple-click anywhere in the line below on this page to select it:
/Library/Application Support/VSearch
Right-click or control-click the line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item named "VSearch" selected. Drag the selected item to the Trash. You may be prompted for your administrator login password.
Repeat with each of these lines:
/Library/LaunchAgents/com.vsearch.agent.plist
/Library/LaunchDaemons/com.vsearch.daemon.plist
/Library/LaunchDaemons/com.vsearch.helper.plist
/Library/LaunchDaemons/Jack.plist
/Library/PrivilegedHelperTools/Jack
/System/Library/Frameworks/VSearch.framework
Some of these items may be absent, in which case you'll get a message that the file can't be found. Skip that item and go on to the next one.
Restart and empty the Trash. Don't try to empty the Trash until you have restarted.
From the Safari menu bar, select
Safari ▹ Preferences... ▹ Extensions
Uninstall any extensions you don't know you need, including any that have the word "Spigot" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
This trojan is distributed on illegal websites that traffic in pirated movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect much worse to happen in the future.
You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that the DownLite developer has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing, has not done so, even though it's aware of the problem. It must be said that this failure of oversight is inexcusable and has seriously compromised the value of Gatekeeper and the Developer ID program. You cannot rely on Gatekeeper alone to protect you from harmful software.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

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

Is there any method, function module, XSLT or anything else for that already?

I tried using the FM (SWA_STRING_REMOVE_SUBSTRING) but I guess it is expecting a particular pattern which is not so apparent in your case. Iu2019ve written a small piece of code which you can try using in a FM or a PERFORM and that should do the trick. Please let me know if you have any questions.

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);
