Removal of String from JTextArea

Does anyone know how to remove a string from a JTextArea. The folowing do not work
t1.remove(s1);
t1.delete(s1);
t1 being the text area and s1 the string

Hello,
If you want to "clear" the string, it's "setText("")".
If you want do remove part of the string, its a little bit more complex ...
String temp = getText();
remove the string from the temp String
setText(temp);
I hope this help

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?

Hi Daniel,
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);

Best way to remove unwanted signs from string

Which is the best way to purify a string from possible dangerous signs? I want to remove all characters that is not a-z or 0-9? how would I go about?

read the string character by character, and check to
see if they're characters you want to remove or not,
by comparing them to the ascii values of characters
you permit. I've used this before, but I can't
remember what exactly it permits, and I'm too lazy to
look up the ascii table :) But this sort of thing
works.
int c = in.read();
while(c!=-1){
if((c<33)||(c<58&&c>44)){
out.write(c);
I thought about that too. But the values in the ASCII table... arn't they a little volatile to use? I mean, will my application work on other systems or systems with other languages?

Remove "Begin Sequence" and other strings from text report

I want to remove the string "Begin sequence", "End sequence" and the pathname of the sequence from my text reports that is generated with 'On The Fly Generation' option set, without this option those strings are not present.
I see that strings are inserted by the 'ProcessOTFStepResult' sub-sequence in the report_txt.seq file, this is an activex call that compile the body of the report.
Thank you in advance,

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,'');

Moving data string from a jtextarea into an array

i was looking for some advice. how would i be able to take chunks of text on a paragraph by paragraph basis and enter them into an array. which would result in paragraph1 in array 0, and so on. is this possible to do? i have never really used straing arrays before, and if anyone knows of any online tutorials it would be a great help
thank u

here you go, forgive the gui, very sloppy looking, press the Click me button to store the jtextarea data into the array and show output button to see what the value stored in the array is. there are 2 classes:

          MyMain main = new MyMain();
          main.createIt();

Your main() method calls removeCd() which obtains the title of

Removing duplicate values from selectOneChoice bound to List Iterator

I'm trying to remove duplicate values from a selectOneChoice that i have. The component binds back to a List Iterator on the pageDefinition.
I have a table on a JSF page with 5 columns; the table is bound to a method iterator on the pageDef. Then above the table, there are 5 separate selectOneChoice components each one of which is bound to the result set of the table's iterator. So this means that each selectOneChoice only contains vales corresponding to the columns in the table which it represents.
The selectOneChoice components are part of a search facility and allow the user to select values from them and restrict the results that are returned. The concept is fine and i works. However if i have repeating values in the selectOneChoice (which is inevitable given its bound to the table column result set), then i need to remove them. I can remove null values or empty strings using expression language in the rendered attribute as shown:
<af:forEach var="item"
items="#{bindings.XXXX.items}">
<af:selectItem label="#{item.label}" value="#{item.label}"
rendered="#{item.label != ''}"/>
</af:forEach>
But i dont know how i can remove duplicate values easily. I know i can programatically do it in a backing bean etc.... but i want to know if there is perhaps some EL that might do it or another setting that ADF gives which can overcome this.
Any help would be appreciated.
Kind Regards

Hi,
It'll be little difficult removing duplicates and keeping the context as it is with exixting standard functions. Removing duplicates irrespective of context changes, we can do with available functions. Please try with this UDF code which may help you...
source>sort>UDF-->Target
execution type of UDF is Allvalues of a context.
public void UDF(String[] var1, ResultList result, Container container) throws StreamTransformationException{
ArrayList aList = new ArrayList();
aList.add(var1(0));
result.addValue(var1(0));
for(int i=1; i<var1.length; i++){
if(aList.contains(var1(i)))
continue;
else{
aList.add(var1(i));
result.addValue(var1(i));

Unable to remove a host from VMM - Error (2606) Unable to perform the job because one or more of the selected objects are locked by another job.

I am unable to remove a host from my Virtual Machine Manager 2012 R2. I receive the following error:
Error (2606)
Unable to perform the job because one or more of the selected objects are locked by another job.
Recommended Action
To find out which job is locking the object, in the Jobs view, group by Status, and find the running or canceling job for the object. When the job is complete, try again.
I have already tried running the following command in SQL Server Management Studio
SELECT * FROM [VirtualManagerDB].[dbo].[tbl_VMM_Lock] where TaskID='Task_GUID'
I received this error back:
Msg 8169, Level 16, State 2, Line 1
Conversion failed when converting from a character string to uniqueidentifier.
I have also tried rebooting both the host and the Virtual Machine Manager Server. After rebooting them both, I still receive the same error when trying to remove the host.
Here are my server details
VMM Server OS = Windows 2012 Standard
VMM Version = 2012 R2 3.2.7510.0
Host OS = Windows 2012 R2 Datacenter
Host Agent Version = 3.2.75.10.0
SQL Server OS = Windows 2012 Datacenter
SQL Version = 2012 SP 1 (11.0.3000.0)

Hi there,
How many hosts are you managing with your VMM server?
The locking job might be the background host refresher job. Did you see any jobs in the jobs view, when the host removal job failed?
If there is no active jobs in the jobs view when this host removal job fails, can you please turn on the VMM tracing, retry the host removal, and paste back the traces for the failed job (search for exception and paste the whole stack)?
Thanks!
