Reg DXL Script for one requirement?

Does anyone help me to write one DXL script ? I tried but could not suceed to complete the DXL script?

Requirement:

I need to extract the data from the attribute (attr1)which will be like  

B1.00

B2.00

B3.00

I need to extract the data from one more attribute which will be like

attr2 B1.01

I need to extract those two attributes and compare the data in the attribute

If  attr2 value ( numeric) is greater than or equal to i need to set another attribute to Boolean value.

Can anyone help me to complete the script?

Let me scribble without any attempt at debugging.  I'll assume the entire attr values must have format "B1.00" without any additional characters (e.g. not "B1.001".

• string   sValid =
  "^"           // beginning of string -
  "([A-Z])"    // match 1 a capital letter  -
  "("            // match 2 starts here.. -
  [1-9]      // a digit 1 through 9-
  \.            // a period -
  [0-9][0-9]    // two digits  -
  ")"        // match 2 ends here -
  "$"       // end of string
• print "sValid = " sValid "\n"
• Regexp reValid = regexp2(sValid)
• bool CheckObject(Object obj)
• {  string Value1 = obj."attr1"
•    string Value2 = obj."attr2"
•    if (reValid Value1)
•    {  Letter1 = Value1[match 1]
•       sValue1 = Value1[match 2]
•       if (reValid Value2)
•       { Letter2 = Value2[match 1]
•          sValue2 = Value2[match 2]
•          rValue1 = realOf(sValue1)
•          rValue2 = realOf(sValue2)
•          if (Letter1 == Letter2 and rValue2 >= rValue1) //
•          then return(true)
•          else return(false)
•       }
•       else return(false)
•    }
•    else return(false)
• }  // end CheckObj()
