Hi,


we are downloading free version of PDF Net and planning to purchase the product.

Our Requirement is ( IN WPF APPLICATION)
We are reading a PDF file which contents some XML tag, and we need to remove that tag from PDF and create new one.

XML contnets like

/* Some text of PDF /

Other XML Contents

/ Some text of PDF */

we want to remove this xml node from PDF file and create other PDF file.

Our code to read pdf content is below

Document pdfDocument = new Document(“input.pdf”);
TextAbsorber textAbsorber = new TextAbsorber();
pdfDocument.Pages.Accept(textAbsorber);
string extractedText = textAbsorber.Text;


In Extracted Text its always return 
"Evaluation Only. Created with Aspose.Pdf. Copyright 2002-2011 Aspose Pty Ltd."
Is this because of evaluation version ? 
How can i achieve our task to remove XML node from PDF ? is it Possible with Your product.

Hi Rashid,


As we asked you for text removing in PDF document with ASPOSE.
we are downloading free version of PDF Net and planning to purchase the product.

We are reading a PDF file which contents some XML tag, and we need to remove that tag from PDF and create new one.

XML contnets like

/* Some text of PDF /

Other XML Contents line 1
Other XML Contents line 2
Other XML Contents line 3
Other XML Contents line 4

/ Some text of PDF */

Our code to read pdf content is below

License license = new License();

string licenseFilePath = Path.Combine(INSTALLPATH, “Aspose.Pdf.lic”);

license.SetLicense(licenseFilePath);
Document pdfDocument = new Document(FILEPATH);

TextAbsorber textAbsorber = new TextAbsorber();

pdfDocument.Pages.Accept(textAbsorber);

string extractedText = textAbsorber.Text;

//NOTE xmlContents are same as described 

string[] textReplaceAll = xmlContents.Split(’\n’);

foreach (string textReplace in textReplaceAll)

{

string oText = textReplace.Trim().TrimEnd(’\r’);

//create TextAbsorber object to find all instances of the input search phrase

TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber(oText);

//set text search option to specify regular expression usage

TextSearchOptions textSearchOptions = new TextSearchOptions(true);

textFragmentAbsorber.TextSearchOptions = textSearchOptions;

//accept the absorber for all the pages

pdfDocument.Pages.Accept(textFragmentAbsorber);

TextFragmentCollection textFragmentCollection = textFragmentAbsorber.TextFragments;

//loop through the fragments

foreach (TextFragment textFragment in textFragmentCollection)

{

//update text and other properties

textFragment.Text = String.Empty;

}

}


MemoryStream outStream = new MemoryStream();


pdfDocument.Save(outStream);


In Extracted Text its always return 
"Evaluation Only. Created with Aspose.Pdf. Copyright 2002-2011 Aspose Pty Ltd."
Is this because of evaluation version ? 
And in new PDF document first line of page is always
"Evaluation Only. Created with Aspose.Pdf. Copyright 2002-2011 Aspose Pty Ltd."

In new PDF document we get below output


Other XML Contents line 4
as you see we are not able to replace all XML Content and its tags,
Only Four lines are replaced by this code.

Is This Because Of Evaluation Version ?
Can It Be Replace All Text From PDF After We Purchase Your Product ?

Thank You.

Hi Mohammad Azharuddin,

Thanks for your inquiry and sharing the sample source code with us.

Yes, the issues you mentioned in you post totally related to Evaluation Version but I am afraid, you are using Aspose.Pdf.lic file in your code, after using this file these issues should be remove. Please make sure that your license subscription is not expired. You may check that by opening your license file in a text editor and check the tag to confirm your license subscription expiry. Can you please confirm this?

Moreover, kindly share the source document with us so that we can test the scenario at our end.

We apologize for your inconvenience.

Thanks & Regards,
