Inputs
  • pattern - An attribute of base type string or a string value. String must be a valid regular expression. The regular expressions used in several Blueriq Studio functions are common Java 1.4 expressions. For a complete documentation we refer to the online java documentation.
  • string - An attribute of base type string or an expression that results in a string.
  • replacement - An attribute of base type string or an expression that results in a string.

Return type

  • string. If the pattern is not found, the original string is returned.

Examples

ExpressionResultTypeREPLACE ":" IN  "hello:world:example" WITH " ""hello world example"StringREPLACE ( "o" , "hello world" , "a" )"hella warld"StringREPLACE

SPLIT

SPLIT returns a multivalued attribute containing every substring that is delimited by the given pattern.

SUBSTRING AFTER


SUBSTRING_AFTER returns Returns the end of a given string after the first occurrence of substring, or an empty string if substring is not found. 


Syntax

Code Block
SUBSTRING AFTER substring IN string
SUBSTRING_AFTER ( string , substring )


Inputs

  • string - An attribute of base type string, an expression that results in a string or a constant string value.
  • substring - An attribute of base type string, an expression that results in a string or a constant string value.


Return type

  • string


Example

ExpressionResultType
SUBSTRING AFTER ":" IN "hello:world""world"String
SUBSTRING_AFTER ( "hello:world:all" , ":" )"world:all"String
SUBSTRING AFTER "a" IN "hello:world"""String
SUBSTRING_AFTER ( "" , "hello" )""String
SUBSTRING_AFTER ( "hello" , "" )"hello"String

SPLIT string ON pattern
SPLIT ( string , pattern )

Inputs

  • string - An attribute of base type string, an expression that results in a string or a constant string value.
  • pattern - An attribute of base type string or a string value. String must be a valid regular expression. The regular expressions used in several Blueriq Studio functions are common Java 1.4 expressions. For a complete documentation we refer to the online java documentation.

Return type

  • string (multivalued)

Example

ExpressionResultTypeSPLIT "Hello world" ON "o"[ "Hell" , " w" , "rld" ]String (multivalued)SPLIT ( "Hello world" , "a" )[ "Hello world" ]String (multivalued)SPLIT "Hello" ON "o"[ "Hell" ]String (multivalued)SPLIT ( "ooo" , "o" )[ ]String (multivalued)SPLIT ( "bot" , "o" )[ "b" , "t" ]String (multivalued)SPLIT ( "boot" , "o" )[ "b" , "", "t" ]String (multivalued)SPLIT ( "booot" , "o" )[ "b" , "", "t" ]String (multivalued)To remove dots from a string in combination with the JOIN function:JOIN ( SPLIT ( "H.E.L.L.O" , "\.") , "" )"HELLO"String

If you use the SPLIT in a default expression on an multivalued attribute, please note that the result will be stored as collection, meaning that all duplicates will be removed. To illustrate this: suppose we have an attribute Test.Splitted (multivalued), which has the default expression SPLIT ( "H.E.L.L.O" , "\."). The result of the expression JOIN ( Test.Splitted , "" ) = "HELO" instead of "HELLO" as in the last example.

REPLACE

The REPLACE function replaces every occurrence of a string pattern within another string with a provided replacement string. The function is case-sensitive.

Syntax

Code Block
REPLACE pattern IN string WITH replacement
REPLACE ( pattern , string , replacement )
( "
O" , "
hello
world
" , "
a
" )
"hello world"StringREPLACE "\s
"
IN "
hello
world example" WITH "
"
"helloworldexample" Panel

EQUALS

EQUALS compares two strings and returns TRUE if and only if they are equal. This function is case sensitive.

UI Text Box
typewarning

Only use this function if you need a case sensitive comparison of two strings. If you want to compare strings case insensitive, use the '=' operator instead.

Syntax

Code Block
string1 EQUALS string2
EQUALS ( string1 , string2 )

Inputs

  • string1 - An attribute of base type string, an expression that results in a string or a constant string value.
  • string2 - An attribute of base type string, an expression that results in a string or a constant string value.

Return type

  • Boolean

Example

ExpressionResultTypeNote"hello" EQUALS "hello"TRUEBooleanEQUALS ( "hello" , "Hello" )FALSEBooleanFALSE because EQUALS is case sensitive"hello" EQUALS "hello "FALSEBooleanFALSE because of trailing spaceEQUALS ( "" , "" )TRUEBoolean
String
REPLACE ( "\d{2}" , "hello1 world22 example333" , "@" )"hello1 world@ example@3"StringREPLACE ( "" , "hello world" , " " )" h e l l o   w o r l d "StringREPLACE "\s" IN "hello world example" WITH "\s""hello\sworld\sexample"String

The first argument is a pattern (regular expression) and can therefore contain specials like \s for a space. The second and third arguments are strings or expressions, so \s will result in \s.
