So basically I am trying to generate html from docx using openxml powertools. It handles whole thing except header and footer. I have file name main.docx, I am trying to create temporary docx file for header and footer and put header and footer of main docx to temp docx in Main Body. So I can use those temp docx to generate html and at end merge all. In this process it's difficult to copy header of file to main body of temp docx. Anyone tried ??? I also tried using documentbuilder but it does not have such method
{
var fi = new FileInfo(file);
Console.WriteLine(fi.Name);
byte[] byteArray = File.ReadAllBytes(fi.FullName);
using (MemoryStream memoryStream = new MemoryStream())
{
memoryStream.Write(byteArray, 0, byteArray.Length);
using (WordprocessingDocument wDoc = WordprocessingDocument.Open(memoryStream, true))
{
var headerText = ExtractHeader(wDoc);
var footerText = ExtractFooter(wDoc);
var headerDocx = CreateHeaderFooterDocx(headerText,fi.Name);
//var footerDocx = CreateHeaderFooterDocx(footerText, "footer.docx");
var headerHTML = ConvertToHtml(headerDocx, outputDirectory,file);
//var FooterHTML = ConvertToHtml(footerDocx, outputDirectory);
var MainBodyHTML = ConvertToHtml(file, outputDirectory, file);
var completeHtml = $@"
<html>
<head><title>DocxToHTML</title></head>
<body>
<header></header>
{MainBodyHTML}
<footer></footer>
</body>
</html>";
File.WriteAllText(fi.Length+".html", completeHtml, Encoding.UTF8);

I tried extracting xml and putting in main body but temp docx does not hep it. Reason I want in above way is that I can get images and link and also stylings.
