Assign Matches output to variable

Help

Hi guys I have a set of 39 values within a Matche’s variable, and what I want to do is iterate through them assigning each value to a string variable to place into Excel rows. This is what I’m thinking of doing, and then adding ‘vCount = vCount + 1’ each time it loops through.

vMyMatchesVariable(vCount) = vExcelRowVariable

If they’re in a list you can loop over them using the For Each activity and use the index property on the activity as the counter. Just be aware that index starts at 0, so when you write to excel you want index+1 (or index+2 if you have a heading).

Hi @jfarnden, so in the Output > Index form of the for each property do I just put a 1? Or how do I make sure it begins on an index of 1? Thanks.

Hi
Instead we can pass that output variable from MATCHES to a FOR EACH activity and mention the type argument as System.Text.RegularExpressions.Match
Inside the loop we can access each match like this in a assign activity
str_output = item.ToString

Cheers @css

Hi @Palaniyappan can you explain that a bit more specifically, as I’m brand new to UiPath. So my matches varable is called vSubStringIndexArray, and I have the for loop setup for each ‘item’ in ‘vSubStringIndexArray’. Now I just need to know what to put in the ‘index’ option of the activity so it starts at an index of 1 and how to get those values into excel.

Fine
Let the variable name be vSubStringIndexArray
And pass this as input to FOR EACH activity
And as we need to access each element in this matches activity we have to change the type argument of the object only then we will be able to access them.
Accessing means directly the element and not with index position, as we are already iterating them in FOR EACH loop so that each element can be obtained in order of index position

For that in for each activity change the type argument property as System.Text.RegularExpressions.Match

—then inside the loop use a assign activity and mention like this
str_output = item.ToString
Here we don’t need to mention the index position rather it will get the value in order one by one

Cheers @css

Hi @Palaniyappan that worked wonderfully, thanks.

Hey @Palaniyappan is there a way to remove duplicate values from a Matches variable?

Yah inside the same for each loop instead of assign activity use a ADD TO COLLECTIONS activity
And mention the input as item.ToString in item property and in collections property mention as list_variable

Where list_variable is of type System.Collections.Generic.List(of string) with default value as New list(of string) defined in the variable panel

—now all the values from matches will be added to that list variable
—next to this for each loop use a assign activity like this
list_variable = list_variable.Distinct().ToList()

Now it will remove all duplicates
Cheers @css
