string replace using regular expression

, ,
1

I would like to remove ISC header info before the error message. Hence I am using string replace using regular expression.

[ISC.0082.9034] Field is absent, field must exist.

The regular expression I am using in search field is /^[ISC/… But I am getting the below error.

org.apache.oro.text.regex.MalformedPatternException: Unmatched in expression.
I know there are other solutions. But Just want to know what am I doing wrong in this case.

Thanks

The [ has special meaning in regex. If you want to use it literally, escape it.

/^[ISC.*] /

assuming that there are no other closing square brackets with a following space in your string.

Chris
My inputs for string.replace service are
inString---->[ISC.0082.9034] Field is absent, field must exist
searchString----->/^[ISC.*] /
replaceString----->X
useRegex----> true

My output value is still the same

[ISC.0082.9034] Field is absent, field must exist. So can you let me know if I am missing something.

I am expecting X Field is absent, field must exist for the output value.

Thanks for your help.

Remove the enclosing slashes.

Hi Srinivas,

I’m not sure we can use regular expressions in replace function to define a boundary and replace them with a single char but if your requirement is to just delete the error code from the error message then this is my suggestion: Form a regular expression which would pattern match numberics(0-9) and ‘.’ which would start with [ISC and end with ‘]’ and and leave the replaceString empty. This would remove the error code.

BUT BEWARE that this would remove any other numbers and . in the whole message.

Another way you can do is to do a 3 step.

[INDENT]1. indexOf(“]”)
2. substring(0,index)
3. replace(substring,replaceString=“”)
[/INDENT]
Hope this helps.

Hi,

If you will use Search String as ^[ISC.*] it will work fine.

cheers!

To elaborate, the surrounding slashes on a regex are only needed when regex is used as a label in a branch step. Other facilities that support regex do not need them.

Thanks Guys, It worked with your inputs.
