Alternative to use String.Split function in BizTalk Orchstration

My requirement is to get the 6th ISA segment value.

The var_ISASegment contains this value "ISA*00*          *00*          *01*FIRST *01*98765LCSAPT*090318*1420*U*00401*000442082*0*T*^~"

Solution:

We will have to use an expression shape and a loop and Expression shape

Place this below condition in the loop

var_counter < 8

 create 3 variables (var_PrvPosition, var_curntPosition, var_counter) with int data type.  

• var_PrvPosition used to store the startup position.  
• var_curntPosition used to store  index of our delimiter 
• var_counter used to store the segment number.

Place below code in the expression shape

var_PrvPosition ++;

var_curntPosition = var_ISASegment.IndexOf("*",var_PrvPosition);

               

var_counter++;

if (counter == 7)

{

  Var_SixthSegment = var_ISASegment.Substring(var_PrvPosition, var_curntPosition – var_PrvPosition));

}

var_PrvPosition = indexCurrentPosition;
