Does pdfA1a support TOC and TOC Item (TOCI) tags?

When converting a docx document that includes a table of content into a Pdf using the PdfCompliance.PdfA1a compliance option we noticed that all table of content elements are tagged as <P> instead of the recommended <TOC> or <TOCI> tags.

Is there a way to generate the PDF using the <TOC> and <TOCI> for table of content elements?


Please ZIP and upload your 1) sample Word document, 2) Aspose.Words generated output PDF file and 3) source code here for testing. Also, please provide complete steps that we can follow on our end to verify/analyze the tags in PDF.

Hi @awais.hafeez,

Thank you very much for your response.

The next ZIP file contains the requested information:

AsposeWords_PDFA1-TOC_Tags.zip (335.2 KB)

  1. Sample Word Document: Example_Guide.docx
  2. Aspose.Words Generated Output: Example_Guide.pdf
  3. Source Code: CodeSnippetToConvertDocxToPDF.txt
  4. Steps to Verify:
  • Open the pdf document with Adobe Acrobat Pro DC
  • Show the Tags option in the toolbar View/Show-hide/Navigation Panes/Tags
  • Click on the Tags options and you will see the generated tags for the Apose.Words generated pdf (Example_Guide.pdf), and a Microsoft Word generated pdf (Example_Guide_savedFromTool.pdf). You will notice that the Aspose.Words generated pdf does not include the TOC tags.
  • For convenience we included a screenshot showing the difference between both Pdfs in the WordPDF-AsposePDF-Tags_TOC.PNG image file.

Please let me know if you need any additional information,

Thank you very much again,
