Hi @shod90

As per my understanding, you are trying to read the data using OCR and the output is OCRText.

use loop condition and or for each activity

then loop through the item

then use If condition and

give the Vraible OCRText in the first operand and then is not empty as shown below image.

Hope this helps,

Usha.

Hi @shod90 ,

The OCRText variable may contain Voidspaces.So just use trim text as shown in below image.

Code:
OCR.ExtractTextWithOCR.ExtractTextFromScreenWithWindowsOcr WindowsOcrLanguage: OCR.WindowsOcrLanguage.English ImageWidthMultiplier: 1 ImageHeightMultiplier: 1 OcrText=> OcrText Text.Trim Text: OcrText TrimOption: Text.TrimOption.Both TrimmedText=> TrimmedText LOOP WHILE (True) = (True) IF IsNotEmpty(OcrText) THEN EXIT LOOP END OCR.ExtractTextWithOCR.ExtractTextFromScreenWithWindowsOcr WindowsOcrLanguage: OCR.WindowsOcrLanguage.English ImageWidthMultiplier: 1 ImageHeightMultiplier: 1 OcrText=> OcrText Text.Trim Text: OcrText TrimOption: Text.TrimOption.Both TrimmedText=> TrimmedText END

Please follow the below flow for contains approach:

In the below flow, I have included variable called SearchText to mention your text or char to check in the extracted OCRTEXT and also i have added messagebox to display ocr text before goes into if condition so that it will give some idea on what is being extracted through OCR on each time extraction.

You can declare variable like searchtext and use that variable in if condition second operand like below.

Code:

SET SearchText TO $'''Power''' OCR.ExtractTextWithOCR.ExtractTextFromScreenWithWindowsOcr WindowsOcrLanguage: OCR.WindowsOcrLanguage.English ImageWidthMultiplier: 1 ImageHeightMultiplier: 1 OcrText=> OcrText Text.Trim Text: OcrText TrimOption: Text.TrimOption.Both TrimmedText=> TrimmedText LOOP WHILE (True) = (True) Display.ShowMessageDialog.ShowMessage Title: $'''Info''' Message: $'''Extracted Text: %OcrText%''' Icon: Display.Icon.None Buttons: Display.Buttons.OK DefaultButton: Display.DefaultButton.Button1 IsTopMost: False ButtonPressed=> ButtonPressed IF Contains(OcrText, SearchText, True) THEN EXIT LOOP END OCR.ExtractTextWithOCR.ExtractTextFromScreenWithWindowsOcr WindowsOcrLanguage: OCR.WindowsOcrLanguage.English ImageWidthMultiplier: 1 ImageHeightMultiplier: 1 OcrText=> OcrText Text.Trim Text: OcrText TrimOption: Text.TrimOption.Both TrimmedText=> TrimmedText END
