这是我用来转换的html内容。但是我在解析它时遇到以下错误。

Answer 1

您可能希望尝试使用其他方法从HTML汇编word文档。根据您的要求，您可以采取以下几种方法之一：

使用OpenXmlSdk组装文档，或：
使用 altChunk 方法

altChunk，是Open XML文字处理的一个特殊功能标记，使您可以嵌入整个Open XML文档或 html页面位于文档中的特定位置

Eric White有一些博客文章描述了这个过程，下面是他突出嵌入html文章的摘录：

使用Open XML SDK的V2：

using (WordprocessingDocument myDoc = WordprocessingDocument.Open("Test1.docx", true))
{
    string altChunkId = "AltChunkId1";
    MainDocumentPart mainPart = myDoc.MainDocumentPart;
    AlternativeFormatImportPart chunk = mainPart.AddAlternativeFormatImportPart(
        AlternativeFormatImportPartType.WordprocessingML, altChunkId);

    using (FileStream fileStream = File.Open("TestInsertedContent.docx", FileMode.Open))
        chunk.FeedData(fileStream);
     AltChunk altChunk = new AltChunk();
     altChunk.Id = altChunkId;
     mainPart.Document
         .Body
         .InsertAfter(altChunk, mainPart.Document.Body.Elements<Paragraph>().Last());
     mainPart.Document.Save();
 }

整篇文章以及示例代码（位于底部）：How to Use altChunk for Document Assembly

Answer 2

使用此选项使用内容获取图像首先创建一个.docx文件，然后在下一个文件中添加Html文档。要使用AltChunk mathod，您必须使用创建的文件来创建文件首先使用默认内容创建动态，因为altChunk不接受空白文件。

1.使用较小的内容创建.docx文件。 2.在默认内容后添加html内容。

try
{strBody = "<html>" + "<body>" + "<div> Word File </div>" + "</body>" + "</html>";
using (MemoryStream generatedDocument = new MemoryStream())
{
using (WordprocessingDocument package = WordprocessingDocument.Create(generatedDocument, WordprocessingDocumentType.Document))
{
MainDocumentPart mainPart = package.MainDocumentPart;
if (mainPart == null)
{
mainPart = package.AddMainDocumentPart();
new Document(new Body()).Save(mainPart);
}

HtmlConverter converter = new HtmlConverter(mainPart);
converter.ExcludeLinkAnchor = true;
converter.RefreshStyles();
converter.ImageProcessing = ImageProcessing.AutomaticDownload;
converter.BaseImageUrl = new Uri(domainNameURL + "Images/");

Body body = mainPart.Document.Body;
converter.ConsiderDivAsParagraph = false;

var paragraphs = converter.Parse({strBody);
for (int i = 0; i < paragraphs.Count; i++)
{
body.Append(paragraphs[i]);
}

mainPart.Document.Save();
}

File.WriteAllBytes(filename, generatedDocument.ToArray());
}

using (WordprocessingDocument myDoc = WordprocessingDocument.Open(filename, true))
{
XNamespace w =
"http://schemas.openxmlformats.org/wordprocessingml/2006/main";
XNamespace r =
"http://schemas.openxmlformats.org/officeDocument/2006/relationships";
string altChunkId = "AltChunkId1";
MainDocumentPart mainPart = myDoc.MainDocumentPart;
AlternativeFormatImportPart chunk = mainPart.AddAlternativeFormatImportPart("application/xhtml+xml", altChunkId);

using (Stream chunkStream = chunk.GetStream(FileMode.Create, FileAccess.Write))
using (StreamWriter stringStream = new StreamWriter(chunkStream))
stringStream.Write(html);
XElement altChunk = new XElement(w + "altChunk",
new XAttribute(r + "id", altChunkId)
);
XDocument mainDocumentXDoc = GetXDocument(myDoc);
mainDocumentXDoc.Root
.Element(w + "body")
.Elements(w + "p")
.Last()
.AddAfterSelf(altChunk);
SaveXDocument(myDoc, mainDocumentXDoc);
}
System.Diagnostics.Process.Start(filename);
}
catch (Exception ex)
{
Response.Write(ex.ToString());
}

在阅读之前的答案和此处的答案后，我使用此功能将庞大的HTML（带有嵌入式图像）转换为Word：https://stackoverflow.com/a/18152334/1863970

public static byte[] HtmlToWord(string html)
{
    using (var generatedDocument = new MemoryStream())
    {
        using (var package = WordprocessingDocument.Create(generatedDocument, WordprocessingDocumentType.Document))
        {
            MainDocumentPart mainPart = package.MainDocumentPart;
            if (mainPart == null)
            {
                mainPart = package.AddMainDocumentPart();
                new Document(new Body()).Save(mainPart);
            }

            HtmlConverter converter = new HtmlConverter(mainPart);
            Body body = mainPart.Document.Body;

            string altChunkId = "myId";

            var memoryStream = new MemoryStream(Encoding.UTF8.GetBytes("<html><head></head><body>" + html + "</body></html>"));

            // Create alternative format import part.
            var formatImportPart = mainPart.AddAlternativeFormatImportPart(AlternativeFormatImportPartType.Html, altChunkId);

            // Feed HTML data into format import part (chunk).
            formatImportPart.FeedData(memoryStream);
            var altChunk = new AltChunk();
            altChunk.Id = altChunkId;

            mainPart.Document.Body.Append(altChunk);

            mainPart.Document.Save();
        }

        return generatedDocument.ToArray();
    }
}
