Match and Replace
The example below explains how to find and match the values corresponding to a defined regular expression and replaces them with a specified value. This example uses activities such as the Find Matching Patterns and Replace Matching Patterns. You can find them in the UiPath.System.Activities package.
This is how the automation process can be built:
- Open Studio and create a new Process.
-
Drag a Sequence container in the Workflow Designer.
-
Create the following variables:
Variable Name
Variable Type
Default Value
StringToAnalyze
String
"I have 10.5 RON in first account and 25 RON in second account!"
AccountMatches
IEnumerable<Match>
 FinalString
String
Â
-
-
Drag a Matches activity inside the Sequence container.
- In the Properties panel, add the variable
StringToAnalyze
in the Input field. - Select the
IgnoreCase
andCompiled
options from the RegexOption drop-down list. - Add the variable
AccountMatches
in the Result field.
- In the Properties panel, add the variable
-
Click the Configure Regular Expression button.
- Select the Advanced option from the RegEx drop-down list.
- Add the expression
([0-9]+\.*[0-9]* RON)
in the Value field. - Select the Exactly option from the Quantifiers drop-down list.
- Select the check box for the IgnoreCase option.
-
Click the Save button.
-
Drag a ForEach activity underneath the Matches activity.
- Inside the ForEach activity change the item to account.
-
In the Properties panel, select the System.Text.RegularExpressions.Match option from the TypeArgument drop-down list.
- Add the variable
AccountMatches
in the Values field.
- Add the variable
- Place a Log Message activity inside the ForEach activity.
- Select the option Info from the Level drop-down list.
- Add the expression
account.ToString
in the Message field.
-
Drag a Replace activity below the ForEach activity.
- In the Properties panel, add the variable
StringToAnalyze
in the Input field. - Add the value
IgnoreCase, Compiled
in the RegexOption field. - Add the expression
"$2 $1"
in the Replacement field. - Add the variable
FinalString
in the Result field.
- In the Properties panel, add the variable
-
Click the Configure Regular Expression button.
- Select the Advanced option from the RegEx drop-down list.
- Add the expression
([0-9]+\.*[0-9]* RON)
in the Value field. - Select the Exactly option from the Quantifiers drop-down list.
- Select the check box for the IgnoreCase option.
- Click the Save button.
-
Place a Log Message activity inside the ForEach activity.
- Select the option Info from the Level drop-down list.
- Add the variable
FinalString
in the Message field.
- Run the process. The robot finds and matches the values corresponding to the defined regular expression and replaces them with the specified value.
