Open XML: Word - Retrieving All Paragraphs Marked As Heading1 Style

Using Word, I created Docx with the standard normal.dot as a test. The difficulty level is Hello-world.

I want to get all the paragraphsthat are written using << 21> " stylein Word.

I can get all the paragraphs, but I don’t know how to filter to heading1.

using (var doc = WordprocessingDocument.Open(documentFileName, false))
{
    paragraphs = doc.MainDocumentPart.Document.Body
                    .OfType<Paragraph>().ToList();
}

    [Test]
    public void FindHeadingParagraphs()
    {

        var paragraphs = new List<Paragraph>();

        // Open the file read-only since we don't need to change it.
        using (var wordprocessingDocument = WordprocessingDocument.Open(documentFileName, false))
        {
            paragraphs = wordprocessingDocument.MainDocumentPart.Document.Body
                .OfType<Paragraph>()
                .Where(p => p.ParagraphProperties != null && 
                            p.ParagraphProperties.ParagraphStyleId != null && 
                            p.ParagraphProperties.ParagraphStyleId.Val.Value.Contains("Heading1")).ToList();
        }
    }
