Hi,

I am working on an assignment in which I have to fetch list of hyperlinks existing in a docx file. The file may contain links in headers/footers as well.
The approach I am using is through OpenXML. I have been able to detect Hyperlinks that are existing in the body of the docx file using the approach below :

IEnumerable<HyperlinkRelationship> hyperlinks = from r in wordDocx.MainDocumentPart.HyperlinkRelationships where ((r.RelationshipType == "http://schemas.openxmlformats.org/officeDocument/2006/relationships/hyperlink")) select r;
foreach (HyperlinkRelationship hr in hyperlinks)
{
 if (isValidURL(hr.Uri.ToString()))
 {
  lstBox.Items.Add(hr.Uri.ToString());
 }
}

Any suggestions on how to iterate through the header/footer document parts and check for existence of Hyperlinks?

Regards!

Have tried that mate. Problem is I am not able to form Hyperlink relationship for the Header/footer part reference.

We need to iterate withing HeaderFooterReference class to create HyperlinkRelationship and then use LINQ Query to find the result. Here is how I resolved this problem.

protected ListBox GetHeaderFooterHyperLinks(WordprocessingDocument wordDocx)
{
     string headerFooterRelationshipID;
     foreach (HeaderFooterReferenceType hdrFtr in wordDocx.MainDocumentPart.Document.Descendants<HeaderFooterReferenceType>())
  {
         headerFooterRelationshipID = hdrFtr.Id.Value;
         IEnumerable<HyperlinkRelationship> hdrFtrLinks = from hdrFooter in wordDocx.MainDocumentPart.GetPartById(headerFooterRelationshipID).HyperlinkRelationships where (hdrFooter.RelationshipType == "http://schemas.openxmlformats.org/officeDocument/2006/relationships/hyperlink") select hdrFooter;
    foreach(HyperlinkRelationship hf in hdrFtrLinks)
    {
       lstBox.Items.Add(hf.Uri.ToString());
    }
  }
  return lstBox;
}
