TextFragmentAbsorber find same text two times

Aspose.PDF Product Family
#1

Hi,

I am using below code to extract PDF content using below code,

            TextAbsorber textAbsorber = new TextAbsorber();
            doc.Pages.Accept(textAbsorber);
            string extractedText = textAbsorber.Text;

I can see MSA audit and PCPA AUDIT found single time in attached SAMPLE_PDF.pdf. but same same word find mutiple time when using below code,
foreach (var tagmodel in ShapesWithSignerTagModel)
{
var pageArray = tagmodel.PageNo.Distinct();
TextFragmentAbsorber absorber = new TextFragmentAbsorber(tagmodel.Tag);

                    foreach (int page in pageArray)
                    {
                        doc.Pages[page].Accept(absorber);
                    }

                    textFragments.AddRange(absorber.TextFragments.AsEnumerable());
                }

                foreach (TextFragment textFragment in textFragments.OrderBy(a => a.Page.Number))
                {
                    textFragment.Text = ""; // **MSA audit** and **PCPA AUDIT** found mutiple times
                }

I have uploaded full sample code in below URL,

The reason you are getting duplicate search results is that you are initializing the TextFragmentAbsorber Class outside the loop due to which previous results of found text do not get cleared from the cache. You need to initiate the instance inside the loop like below:

foreach (int page in pageArray)
{
 TextFragmentAbsorber absorber = new TextFragmentAbsorber(tagmodel.Tag);
 doc.Pages[page].Accept(absorber);
}

Feel free to let us know in case you still notice any issues.
