Hello
Thank you for additional information. I
think in this case, you should reapply a style for each Heading paragraph. Please see the following code:
Document doc = new Document("C:\\Temp\\InputDoc.docx");
MemoryStream htmlStream = new MemoryStream();
HtmlSaveOptions saveOptions = new HtmlSaveOptions();
doc.Save(htmlStream, saveOptions);
string htmlText = Encoding.UTF8.GetString(htmlStream.GetBuffer());
htmlStream.Close();
StringBuilder lSbTemp = new StringBuilder();
lSbTemp.Append("
");
htmlText = lSbTemp.ToString() + htmlText;
// Get bytes from string
byte[] htmlBytes = Encoding.UTF8.GetBytes(htmlText);
// Create memory stream
MemoryStream newHtmlStream = new MemoryStream(htmlBytes);
// Create document
Document outDoc = new Document(newHtmlStream);
foreach (Paragraph paragraph in
outDoc.GetChildNodes(NodeType.Paragraph, true))
{
switch
(paragraph.ParagraphFormat.StyleIdentifier)
{
case StyleIdentifier.Heading1:
case StyleIdentifier.Heading2:
case StyleIdentifier.Heading3:
case StyleIdentifier.Heading4:
case StyleIdentifier.Heading5:
case StyleIdentifier.Heading6:
case StyleIdentifier.Heading7:
case StyleIdentifier.Heading8:
case StyleIdentifier.Heading9:
Style
currentStyle = paragraph.ParagraphFormat.Style;
paragraph.ParagraphFormat.ClearFormatting();
foreach
(Run run in
paragraph.GetChildNodes(NodeType.Run, true))
run.Font.ClearFormatting();
paragraph.ParagraphFormat.Style =
currentStyle;
break;
default:
// do
nothing.
break;
}
}
outDoc.Save("C:\\Temp\\out.docx");
Best
regards,
