Compare multiple pdf file at once and generate report

Dear team,

In our company we are having a requirement to validate multiple pdf document at once.

We have more than 350 PDF file generate once we run the regression suite in automation and manually we are validating all those 350 file to avoid any mismatches in the PDF Letters.

In order to do manually, we are looking something where it will validate all PDF files at once.

Could some help me out with such requirement.

Your help is highly appreciated.

Thanks

Consider using the PDFDocument class from the LEADTOOLS PDF toolkit (https://www.leadtools.com/sdk/pdf). This class can be used to parse all text objects from your PDF, provided that the text is stored as searchable text.

Once you have extracted the text, you can perform string comparison to check that they match with your base PDF file.

The code to extract all text object from a PDF file will look like this:

using (PDFDocument document = new PDFDocument(pdfFileName))
{
PDFParsePagesOptions options = PDFParsePagesOptions.Objects;
document.ParsePages(options, 1, -1);
StringBuilder textLine = new StringBuilder();
foreach (PDFDocumentPage page in document.Pages)
{
IList objects = page.Objects;
foreach (PDFObject obj in objects)
{
if (obj.ObjectType == PDFObjectType.Text)
textLine.Append(obj.Code);
}
}
}

Once you have parsed all the text, you can use textLine.ToString()to obtain all the text as a string. You can then compare the string to a reference to see if they match:
