QTP Mid Function

Mid Function:

The Mid function returns a specific number of characters from a strings.

HP QTP MID Function

Note:We can Use the Len function to determine the number of characters in a string.

Syntax:

Len(string)

Ex:

str1="d3g4 g5h6j6"
strlen=len(str1)
MsgBox strlen

Which will returns total characters count in a string as str1 having 11 includng spaces.

Lets see Mid function

Syntax:

Mid(String,start,[Optional] Length)

String : The specified string from which characters are returned.

Start : The starting position of the String

Length : [Optional] The number of characters to get or return.

Example 1:

Str2 = "Hello World"
  flen=Mid(str2,1,1) 'Which will return first character from the string because starting is 1 and length is 1

print "Specific character from the string is :"&flen

Output is :Specific character from the string is :d

Another Example:Get all characters, starting at position 1

    str3="d3g4g5h6j6"
    rlen=Mid(str3,1)
print "Specific character from the string is :"&rlen

In this above example we have mentioned only starting position but not mention length means ending position

Output is :Specific character from the string is :d3g4 g5h6j6

Example 3:

How to find numerics in a string

Lets see the below example

1.Declare the string
str1="d3g4g5h6j6"
strlen=len(str1) ' Find length of the string
l_num="" 'Here we are taking this one as empty to store the strings values   

For i=1 to strlen ' Use for loop to check entire string for each characters            y=mid(str1,i,1) ' i have taken start position at 1 and length position at 1 

If ( isnumeric(y)=True) Then 'Verify if in string numerics presents in case it true then it will return

        l_num= l_num & y
 Print "l_num is" &l_num
 'In l_num it will save the numerics data with one by one as below
                End If
    Next
    Print "Numerics in Specified String is :" &l_num 'Here it will display output

Output:

l_num is :3

l_num is :34

l_num is :345

l_num is :3456

l_num is :34566

Numerics in Specified String is :34566
