Try this:

Assign (String)
pattern = "Purchase\sDate.+?:\s+(?<purchase>[\d\/]+?)\s+In-service\sDate.+?:\s+(?<service>[\d\/]+?)"

Assign (Match)
match = System.Text.RegularExpressions.Regex.Match(MyVar, pattern)

Assign (String)
purchase = match.Groups("purchase").ToString

Assign (String)
service = match.Groups("service").ToString

This worked!! Thank you so much.
You have been so helpful! Do you have any tips on how to automate drop-down menus? I need the database to choose the correct option in the drop down menu that matches the extracted text.

SelectItem Activity?

I have tried this activity, I am just unsure if I can use it without quoting the exact text? - Each pdf document will have a different extracted value, so how do I indicate it to choose whatever the extracted value is/value stored in the variable?

Well, you have to find a way to map the value to the drowpdown option. Depends of both the values and the options.

I have figured out all String drop downs using the type into activity, but I am having trouble with the numeric values, and am unsure how to select these in the drop down using my stored variable, any ideas?

Hi there,
Going back to extracting these dates, how would I extract each individual part of the date? (For example: extracting just the “03” from the in service date: “03/10/2020”
And then same for the day and year,
Anything helps!! Thank you!!

Hello,

You can get a DateTime from the string or you can continue process your strings with regex like below.

Assign (String)
pattern = "\b(?<month>\d{2})\/(?<day>\d{2})\/(?<year>\d{4})\b"

Assign (Match)
match = Regex.Match(text, pattern)

Assign (String)
day = match.Groups("day").ToString

Assign (String)
month = match.Groups("month").ToString

Assign (String)
year = match.Groups("year").ToString

That worked! Thanks so much! So how would the code change for extracting the individual parts from the Purchase Date?

33

It might be a good practice for you.

Some hints:

  • you know how to extract date’s details
  • you know how to extract this date
  • you can make the substitution

Good Afternoon

Sorry to Interrupt, Even i have some question on regex
“05/02/2019 91640.00 52974.00 38666.00 2342299.00”
This is my pattern and have multiple value of same pattern, i want to scrape this specific value “38666.0”.
Even i applied regex (?<=\d{2}/\d{2}/\d{4}\s\d*.\d*\s\d*.\d*\s)(.)(?=\s\d.\d*) and it got worked also.
can i get any alternative simple regex pattern

Thanks in advance

As i am new to regex. I want to learn so just asked can u suggest some sites so i can learn to write pattern

import System.Text.RegularExpressions

Assign (String)
pattern = "(?<date>\d{2}\/\d{2}\/\d{4})\s+(?<first>[\d\.]+)\s+(?<second>[\d\.]+)\s+(?<third>[\d\.]+)\s+(?<fourth>[\d\.]+)\s+"

Assign (Decimal)
result = CDec(Regex.Match(myText, pattern).Groups("third").Value)

I saved it on regex101 for you to examine. The right pane will help you on your journey. I mostly learn throught Perl and Python documentation and by practice (try parsing urls, its quite easy). Here is a link but I didn’t use it (Regular Expression Tutorial - Learn How to Use Regular Expressions)

Thank you so much :slight_smile:
