C# Pdf to Text with values in multiple line

问题

Hi I have a pdf with content as following : -

Property Address: 123 Door         Form Type: Miscellaneous
                  ABC City
                  Pin - XXX

So when I use itextSharp to get the content, it is obtained as follows -

Property Address: 123 Door Form Type: Miscellaneous ABC City Pin - XXX

The data is mixed since it is in next line. Please suggest a possible way to get the content as required. Thanks

Property Address: 123 Door ABC City Pin - XXX Form Type: Miscellaneous

The following code using iTextSharp helped in formatting the pdf -

PdfReader reader = new PdfReader(path);
int pagenumber = reader.NumberOfPages;
for (int page = 1; page <= pagenumber; page++)
{
    ITextExtractionStrategy strategy = new SimpleTextExtractionStrategy();
    string tt = PdfTextExtractor.GetTextFromPage(reader, page , strategy);
    tt = Encoding.UTF8.GetString(ASCIIEncoding.Convert(Encoding.Default, Encoding.UTF8, Encoding.Default.GetBytes(tt)));
    File.AppendAllLines(outfile, tt, Encoding.UTF8);
}

            PdfDocument pdfDoc = new PdfDocument(new PdfReader(filePath));

            //CustomFontFilter fontFilter = new CustomFontFilter(rect);
            FilteredEventListener listener = new FilteredEventListener();

            // Create a text extraction renderer
            LocationTextExtractionStrategy extractionStrategy = listener
                .AttachEventListener(new LocationTextExtractionStrategy());

            // Note: If you want to re-use the PdfCanvasProcessor, you must call PdfCanvasProcessor.reset()
            new PdfCanvasProcessor(listener).ProcessPageContent(pdfDoc.GetFirstPage());

            // Get the resultant text after applying the custom filter
            String actualText = extractionStrategy.GetResultantText();

            pdfDoc.Close();
