Hi,

Heading and subheading are just Paragraph elements with a specific style.

So what you can do is search for the Paragraph element of the targeted style and remove it.
For example, something like this:

var document = DocumentModel.Load("input.docx");

string headingName = "heading 3";
string listNumber = "1.1.1";

document.CalculateListItems();

var paragraph = document.GetChildElements(true, ElementType.Paragraph)
    .Cast<Paragraph>()
    .FirstOrDefault(p =>
        p.ParagraphFormat.Style?.Name == headingName &&
        p.ListItem.ToString().TrimEnd() == listNumber);

paragraph.Content.Delete();

document.Save("output.docx");

I hope this helps.

Hi Sonu,

Try something like this:

var document = DocumentModel.Load("input.docx");

var headings = document.GetChildElements(true, ElementType.Paragraph)
    .Cast<Paragraph>()
    .Where(p => p.ParagraphFormat.Style != null && p.ParagraphFormat.Style.Name.StartsWith("heading "))
    .ToList();

string listNumber = "1.1";
document.CalculateListItems();

for (int i = 0; i < headings.Count; i++)
{
    var heading = headings[i];
    if (heading.ListItem.ToString().TrimEnd() != listNumber)
        continue;

    var start = heading.Content.Start;

    // If it's the last heading paragraph, we'll delete the whole content from its start to the end of the document.
    // Otherwise, we'll delete the content from the current heading's start to the next heading's start.
    var end = i == headings.Count - 1 ?
        document.Content.End :
        headings[i + 1].Content.Start;

    new ContentRange(start, end).Delete();

    // If you want to repeat this process to delete some other heading
    // you'll need to remove the heading that we just deleted from the headings list
    // and recalculate the list numbers.
    //headings.RemoveAt(i);
    //document.CalculateListItems();

    break;
}

document.Save("output.docx");

I hope this helps.

Regards,
Mario
