Regular Expression with RegExp

Practically We can use RegExp Object basically in QTP for following purpose.

1. To find the regular expression from the string

2. And to replace the match value from the string

This Object have some properties and Methods.

Properties:

IgnoreCase:  By default regular expression is case sensitive, to make it case insensitive, set value as “True”

Pattern: We can define the pattern of regular expression in the pattern property. Pattern can include literal and meta characters like .,*,/d 

Global: To return or replace all matches, set Global as True. If set as False, finds the first match only

Methods:

Execute and Replace are the Methods that can be use by RegExp Object

   Execute method has following properties:

o    Item

Item.value – value of item in the collection

Firstindex – First instance of match location

o    Count – Count of instances matching the regular expression

Below code will give you an idea how we can use regular expression:

Set newRegExp = New RegExp

newRegExp.IgnoreCase = True

newRegExp.Global = True

newRegExp.Pattern = ".*a" 'This is the pattern that we have to search into the string

testString = "zeeshan" 'This is the string where we have to perform our search

Set colmatch = newRegExp.Execute(teststring)

For each match in colmatch

Print "Match Value at Fist Location--" &match.Value

print "Total Count for matches--" &colmatch.count

Next

boolMatch = newRegExp.Test(teststring)

Print boolMatch

newRegExp.pattern ="a"

strString = newRegExp.replace(teststring,"b")

Print "Replace String is --"& strstring

Output:
