RegEx to String

I am RPA developer Newbie and I have trying to figure out how to use RegeX to isolate sections of a word and text document, using separate RegEx expressions. When i put the sample text into the RegEx wizard and input the formula it highlights the section(s) i am looking for. But, when i run the bot, i consistently get an error message, saying that the output is null. I have attached my RegEx equations and the subsequent Main file that i am using. If anyone can offer any assistance I would greatly appreciate it .

Main.xaml (255.2 KB)

.txt file that contains the document the RegEx is being applied to.testfilecharlie.txt (10.3 KB)

RegEx equations
regex equation.txt (662 Bytes) project.json (968 Bytes)

Hi @jbrown2019,
If your regex highlights only this one record then you need to assign it to output and use it like this:

Good Morning Pablito,

I tried using the regexoutput(0).Groups(0).ToString and got the error below:

Can you offer any additional assistance ?

Is your matches activity returns only one thing or more results? Can you show example of text input and output of regex? You can use this site for better overview:

The matches activity returns only 1 result, the section that i am looking for. When input the complete sample word document into the regex 101, with the regex formula (?<=INTRODUCTION\n\n)(.*)(?=\n\nMAJOR) it highlighted the desired section.

In regex attribute mark multiline as one of parameters. This should work:
Without this it can’t catch whole phrase as it’s not written in one line together so it returns empty record :wink:



You could try regexoutput(0).groups(0).value.
For me this always works.

With kind regards

Pablito, i added the Regex options and i am still getting the same error. I am not sure if Uipath like my regex formula because it seems like a null value is continuously returned.

I tried your recommendation and it did not work. I provide my main file and the additional files that go along with that, could you look at what i did and let me know if you see something that i don’t see

this is another image of the error i am getting

Are you able to paste here text example so I could test it by myself?

Text example: ( i want to pull only the text under the section “Introduction”

Thanks for input data. I tested it and seems that in this particular case you’ve found a bug :slight_smile:. Seems that regex wizard in activity have a problem with proper "\n" recognition. Instead of this be sure that you regex attributes are like below:
And for each "\n" there should be "\r" in the front. So your regex formula should look like this:
So the output is:

Thanks for being patient. I reported this bug as well :slight_smile:
