eraseBetween

Delete substring between start and end points

Syntax

newStr = eraseBetween(str,startPat,endPat)

newStr = eraseBetween(str,startPos,endPos)

newStr = eraseBetween(___,Boundaries=bounds)

Description

newStr = eraseBetween(str,startPat,endPat) deletes all characters from str that occur between the substrings startPat and endPat, but does not delete startPat and endPat themselves. eraseBetween returns the remaining text as newStr.

newStr = eraseBetween(str,startPos,endPos) deletes all characters from str that occur between the positions startPos and endPos, including the characters at those positions.

newStr = eraseBetween(___,Boundaries=bounds) forces the starts and ends specified in any of the previous syntaxes to be either inclusive when bounds is "inclusive", and exclusive when bounds is "exclusive". For example, eraseBetween(str,startPat,endPat,Boundaries="inclusive") deletes startPat, endPat, and all the text between them.

Note

Only Stateflow^® charts that use MATLAB^® as the action language support the eraseBetween operator.

Examples

Erase Text Between Two Patterns

Delete the substring that is between Hello and !.

h = "Hello, world!"
startPat = "Hello"
endPat = "!"
x = eraseBetween(h,startPat,endPat)

Erase Text Between Start and End Positions

Delete the substring that is between positions 6 and 12.

h = "Hello, world!"
x = eraseBetween(h,6,12)

Erase Text with Inclusive and Exclusive Boundaries

Delete text from string arrays with inclusive or exclusive boundaries.

h = "Hello, world!"
x = eraseBetween(h,6,12,Boundaries="exclusive")

h = "Hello, world!"
x = eraseBetween(h,6,12,Boundaries="inclusive")

Limitations

• This operator does not support structures. For more information about structures in Stateflow, see Access Bus Signals Through Stateflow Structures.
