Hi, I’m trying to extract data in a pdf based on keywords.The same data is available in multiple pages, starting from the second page and the keyword/data is not at the same position on every page. I used activities like get OCR Text,Anchor Base,Scrapings,etc. Is there anyway to extract the same data in multiple pages based on the occurrence of the keyword rather than it’s position.
Thank you …
