Hi @fairymemay

You can try using the UiPath.PDF activities. Use the Read PDF Text activity available on this activity pack to get the data into a string.

Now, you can use the Matches activity and build a tegex to match the pattern through the inbuilt regex builder…

Let know if this helps…

@Lahiru.Fernando yes, now I can​ read​ pdf​ and​ get​ to​ data​ completed.
But I don’t know​ how​ to​ write​ regex​ in​ matches.

Hi @fairymemay

Hope these steps would help you resolve this

—read the pdf with READ PDF activity and get the output as a string variable named str_output

—now use Matches activity and mention the below expression to get the numbers you were expecting and this can be used even if there are more numbers than mentioned in question


@fairymemay - Assuming that page has more number values than the one provided here…I am anchoring the “No.” for the positive look ahead first…

Regex Pattern : (?<=เลขที่ : )[\d-.,]+

For the Total Amount: You can assign it to 4 amount variables using Multiassign activity …

Regex Pattern: (?<=จํานวนเงินรวม\s+)([\d.,]+)\s+([\d.,]+)\s+([\d.,]+)\s+([\d.,]+)

Write Line code: "Amt 1==> " + StrOutput(0).groups(1).ToString + vbcr +"Amt 2==> " + StrOutput(0).groups(2).ToString + vbcr +"Amt 3==> " + StrOutput(0).groups(3).ToString + vbcr +"Amt 4==> " + StrOutput(0).groups(4).ToString

Hope this helps…
