Output                                                                                                        

  • Result -  List<KeyValue<string,string>> of differences is computed which describe the transformation of text1 into text2.

Steps of Using Compare Text

  1. Open iRobo Studio, and then open a new Workflow.
  2. Drag Compare Text Format Activity to the Sequence.
  3. Enter the original text in Text 1 field in Property Panel.
  4. Enter the derivative text in Text 2 field from the Property Panel.
  5. Create List<KeyValue<string,string>> from Variable Table , then add the value in Result field in Property Panel.

For example: (Comparison)

  1. Drag MessageBox Activity to  the Sequence and add the Output Variable in Message field.

     Note: 

         For Example:(Comparison.item(*)). where the item(0), specify if it's an insertion.

   if the item(1), specifies a deletion and if item(2) defines the equality.
   Then the output text is divided into two elements:

   First element describes if it's (Insertion,Deletion,Equality).

   Second element specifies the affected text. 

   Example:

Input:

  Text1: Hello World.

  Text2 Goodbye World.

Output:

  List<KeyValuePair<string, string>> of differences is computed which describe the transformation of text1 into text2.

  The first element specifies if it is an insertion (1), a deletion (-1) or an equality (0). 

  The second element specifies the affected text.

  Therefore, the result for the above Text1 and Text2 is: [(DELETE, Hello), (INSERT, Goodbye), (EQUAL, World.)]
