C# - Extract pages based on a keyword match

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

This code will iterate through all pages in a PDF file and if the extracted text contains the 'keyword' then the page is added to a list and all matching pages are extracted into a new document.

Of course, you can make the matching more complex to suit your needs.

             string keyword = "garden";

        string extractPages = "";
        int foundCount = 0;

        QP.LoadFromFile("originalfile.pdf", "");

        // Iterate through each page in the document
        for (int page = 1; page <= QP.PageCount(); page++)
        {
            // look for pages that match

            QP.SelectPage(page);
            string TextContent = QP.GetPageText(0);  // Can also use option 8.

            if (TextContent.Contains(keyword))  // we found a page
            {
                if (foundCount != 0)
                    extractPages = extractPages + ",";

                extractPages = extractPages + page.ToString();

                foundCount++;
            } 
        }

        if (foundCount > 0)
        {
            QP.ExtractPageRanges(extractPages);
            QP.SaveToFile("out.pdf");
        }
        else
            MessageBox.Show("Keyword not found");

        QP.RemoveDocument(QP.SelectedDocument());
    }
