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.

Andrew.

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());

}
