我如何从 html 字符串创建单词 header

Question

我正在从 html 字符串生成一个 word docx 文件，并使用各种文章我发现了如何向该文档添加简单的 header 和页脚。我现在需要做的是也从 html 字符串生成 header，但我正在努力寻找如何完成此操作的示例。本题作者： Export docx/doc First Header and Footer as docx File Using openXML 说他已经做到了，但不幸的是他没有发布示例。

我下面的代码成功添加了一个 header 但正如您从代码中看到的那样，它只会将 html 作为文本添加到 header 中，而我想传入一个 html 字符串，并且显示在 header 中的格式为 html.

有人做过吗？

static void AddHeaderPart(MainDocumentPart mainPart, string headerHtml, Encoding encoding)
        {
            if (mainPart == null || string.IsNullOrEmpty(headerHtml))
            {return;}

            // Create a new header part.
            HeaderPart headerPart = mainPart.AddNewPart<HeaderPart>();

            // Get Id of the headerPart.
            string rId = mainPart.GetIdOfPart(headerPart);


            // Call GenerateHeaderPartContent
            GenerateHeaderPartContent(mainPart, headerPart, headerHtml, encoding);

            // Get SectionProperties and Replace HeaderReference with new Id.
            IEnumerable<SectionProperties> sectPrs = mainPart.Document.Body.Elements<SectionProperties>();
            foreach (var sectPr in sectPrs)
            {
                // Delete existing references to headers.
                sectPr.RemoveAllChildren<HeaderReference>();

                // Create the new header reference node.
                sectPr.PrependChild<HeaderReference>(new HeaderReference() { Id = rId, Type = HeaderFooterValues.Default });
            }

        }

static void GenerateHeaderPartContent(MainDocumentPart mainPart, HeaderPart headerPart, string headerHtml, Encoding encoding)
        {
            Header header1 = new Header() { MCAttributes = new MarkupCompatibilityAttributes() { Ignorable = "w14 wp14" } };
            header1.AddNamespaceDeclaration("wpc", "http://schemas.microsoft.com/office/word/2010/wordprocessingCanvas");
            header1.AddNamespaceDeclaration("mc", "http://schemas.openxmlformats.org/markup-compatibility/2006");
            header1.AddNamespaceDeclaration("o", "urn:schemas-microsoft-com:office:office");
            header1.AddNamespaceDeclaration("r", "http://schemas.openxmlformats.org/officeDocument/2006/relationships");
            header1.AddNamespaceDeclaration("m", "http://schemas.openxmlformats.org/officeDocument/2006/math");
            header1.AddNamespaceDeclaration("v", "urn:schemas-microsoft-com:vml");
            header1.AddNamespaceDeclaration("wp14", "http://schemas.microsoft.com/office/word/2010/wordprocessingDrawing");
            header1.AddNamespaceDeclaration("wp", "http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing");
            header1.AddNamespaceDeclaration("w10", "urn:schemas-microsoft-com:office:word");
            header1.AddNamespaceDeclaration("w", "http://schemas.openxmlformats.org/wordprocessingml/2006/main");
            header1.AddNamespaceDeclaration("w14", "http://schemas.microsoft.com/office/word/2010/wordml");
            header1.AddNamespaceDeclaration("wpg", "http://schemas.microsoft.com/office/word/2010/wordprocessingGroup");
            header1.AddNamespaceDeclaration("wpi", "http://schemas.microsoft.com/office/word/2010/wordprocessingInk");
            header1.AddNamespaceDeclaration("wne", "http://schemas.microsoft.com/office/word/2006/wordml");
            header1.AddNamespaceDeclaration("wps", "http://schemas.microsoft.com/office/word/2010/wordprocessingShape");

            Paragraph paragraph1 = new Paragraph();

            ParagraphProperties paragraphProperties1 = new ParagraphProperties();
            ParagraphStyleId paragraphStyleId1 = new ParagraphStyleId() { Val = "Header" };

            paragraphProperties1.Append(paragraphStyleId1);

            //This adds the headerHtml as text - how to add it as html?
            Run run1 = new Run();
            Text text1 = new Text();
            text1.Text = headerHtml;

            run1.Append(text1);

            paragraph1.Append(paragraphProperties1);
            paragraph1.Append(run1);

            header1.Append(paragraph1);

            headerPart.Header = header1;
        }

因此下面的代码使用 altChunk 将 html 添加到 header 中。它并不完美，因为当我使用 OpenXmlValidator 验证生成的文档时出现验证错误，尽管该文档仍然可以在 word 中打开，但我将其作为答案发布在这里，因为它确实按照我上面的要求进行操作并且它可能对其他人有帮助：

static void GenerateHeaderPartContent(MainDocumentPart mainPart, HeaderPart headerPart, string headerHtml)
        {
            Header header1 = new Header() { MCAttributes = new MarkupCompatibilityAttributes() { Ignorable = "w14 wp14" } };
            header1.AddNamespaceDeclaration("wpc", "http://schemas.microsoft.com/office/word/2010/wordprocessingCanvas");
            header1.AddNamespaceDeclaration("mc", "http://schemas.openxmlformats.org/markup-compatibility/2006");
            header1.AddNamespaceDeclaration("o", "urn:schemas-microsoft-com:office:office");
            header1.AddNamespaceDeclaration("r", "http://schemas.openxmlformats.org/officeDocument/2006/relationships");
            header1.AddNamespaceDeclaration("m", "http://schemas.openxmlformats.org/officeDocument/2006/math");
            header1.AddNamespaceDeclaration("v", "urn:schemas-microsoft-com:vml");
            header1.AddNamespaceDeclaration("wp14", "http://schemas.microsoft.com/office/word/2010/wordprocessingDrawing");
            header1.AddNamespaceDeclaration("wp", "http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing");
            header1.AddNamespaceDeclaration("w10", "urn:schemas-microsoft-com:office:word");
            header1.AddNamespaceDeclaration("w", "http://schemas.openxmlformats.org/wordprocessingml/2006/main");
            header1.AddNamespaceDeclaration("w14", "http://schemas.microsoft.com/office/word/2010/wordml");
            header1.AddNamespaceDeclaration("wpg", "http://schemas.microsoft.com/office/word/2010/wordprocessingGroup");
            header1.AddNamespaceDeclaration("wpi", "http://schemas.microsoft.com/office/word/2010/wordprocessingInk");
            header1.AddNamespaceDeclaration("wne", "http://schemas.microsoft.com/office/word/2006/wordml");
            header1.AddNamespaceDeclaration("wps", "http://schemas.microsoft.com/office/word/2010/wordprocessingShape");

            Paragraph paragraph1 = new Paragraph();
            ParagraphProperties paragraphProperties1 = new ParagraphProperties();
            ParagraphStyleId paragraphStyleId1 = new ParagraphStyleId() { Val = "Header" };

            paragraphProperties1.Append(paragraphStyleId1);
            paragraph1.Append(paragraphProperties1);

            string altChunkId = "AltChunkId1";
            AlternativeFormatImportPart chunk = headerPart.AddAlternativeFormatImportPart(
                AlternativeFormatImportPartType.Html, altChunkId);

            // Note that headerHtml should be full html, not just a snippet
            // eg. <html><h1>My Header</h1></html> is OK
            // <h1>My Header</h1> is not OK
            MemoryStream ms = new MemoryStream(new UTF8Encoding(true).GetPreamble().Concat(Encoding.UTF8.GetBytes(headerHtml)).ToArray());

            chunk.FeedData(ms);

            AltChunk altChunk = new AltChunk();
            altChunk.Id = altChunkId;

            Run run1 = new Run();
            RunProperties runProps = new RunProperties();
            NoProof noProof1 = new NoProof();
            runProps.Append(noProof1);

            run1.Append(runProps);
            run1.Append(altChunk);

            paragraph1.Append(run1);
            header1.Append(paragraph1);

            headerPart.Header = header1;
        }
