I need to get this string before my separator, in this case a pipe character ('|').

So if I have this data:

Malcolm Bell Landgraab | EMP-00012 | Consultant
Juliawati Sandra | EMP-00003 | Consultant

I want this output:

['Malcolm Bell Landgraab', 'EMP-00012', 'Consultant']
['Juliawati Sandra', 'EMP-00003', 'Consultant']

How can I accomplish this task?

enter image description here

  • Use someString.split('\\|'). I cleaned up your question for you, they're a lot more accessible as text. – Adrian Larson Sep 28 '16 at 4:00

    @AdrianLarson I think that will still provide an output with white spaces for some characters – Mohith Shrivastava Sep 28 '16 at 4:02
  • @MohithShrivastava Your answer was close, you just forgot about the regular expression part of String.split. You could still fix your answer... – sfdcfox Sep 28 '16 at 4:10
  • @sfdcfox Thanks ! Yes I realized it .Looks like eric has it covered before me – Mohith Shrivastava Sep 28 '16 at 4:22
  • @Vikolai - Is that one string with two rows or two separate strings? – Eric Sep 28 '16 at 4:31

I aM splitting it with respect to newline character and | character. This will work for you.

String inputString='Malcolm Bell Landgraab | EMP-00012 | Consultant\nJuliawati Sandra | EMP-00003 | Consultant';
String []rowsData=inputString.split('\n');

for(String individualROw : rowsData){
    String[] rowArray = individualROw.split('\\|');
        System.debug('[\''+rowArray[0].trim()+'\',\''+rowArray[1].trim()+'\',\''+rowArray[2].trim()+'\']\n' );
        }

If you only want record of Employee only Print rowArray[1] and you are good to go.

This will split it and remove whitespace:

String initialString = 'Malcolm Bell Landgraab | EMP-00012 | Consultant';
String[] results = initialString.trim().split('\\s*\\|\\s*');
system.debug(results);

Of course you will want to add in all the usual checks for null, errors, etc.

For a single string this will get you the EMP part as requested in your comments:

Note I am not the best at regex so best I can do at this point:

Pattern MyPattern = Pattern.compile('(?<=EMP)([^\\s\\|]*)(?=[$\\s\\|])');
Matcher MyMatcher = MyPattern.matcher(initialString);
Boolean result = MyMatcher.find();
String emp;
if(result){
    emp = 'EMP' + MyMatcher.group(0);
}
system.debug(emp);
  • thanks, but how if i just want to get the EMP-00012 only? @eric – Vikolai Sep 28 '16 at 4:24
  • @Vikolai - That is a different question. It would just be a matter of using the right regex expression and has nothing to do with your original question – Eric Sep 28 '16 at 4:26
  • so i need to post one more question? with my point is to ask how to get string based on pipe separator '|' ? @eric what i want achieve is comparing EMP-00012 with my other field, so i just need to get EMP-00012 – Vikolai Sep 28 '16 at 4:29
  • @Vikolai - See updated answer. Note only for a single string. If multiple string you will need to split them and iterate over the individual ones – Eric Sep 28 '16 at 4:44
  • @Vikolai - Curious, where in you question did you actually state that all you wanted was the "EMP-xxx' part cause I do not see it in any form? In the future if you want a question answered you actually need to put it in the question that you post. It is very difficult to read into questions when they are posted as text – Eric Sep 28 '16 at 5:01
