问题描述
如何在asp.net C#中使用OpenXML在现有的.docx文件中添加/添加HTML内容?
How do I add/append HTML content in an existing .docx file, using OpenXML in asp.net C#?
在现有的Word文件中，我想附加html内容部分. 例如:
In an existing word file, I want to append the html content part. For example:
在此示例中，我想将"This is a Heading"放置在H1标记内.
In this example, I want to place "This is a Heading" inside a H1 tag.
这是我的代码
protected void Button1_Click(object sender, EventArgs e)
{
try
{
using (WordprocessingDocument doc = WordprocessingDocument.Open(@"C:\Users\admin\Downloads\WordGenerator\WordGenerator\FTANJS.docx", true))
{
string altChunkId = "myId";
MainDocumentPart mainDocPart = doc.MainDocumentPart;
var run = new Run(new Text("test"));
var p = new Paragraph(new ParagraphProperties(new Justification() { Val = JustificationValues.Center }), run);
var body = mainDocPart.Document.Body;
body.Append(p);
MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes("<html><head></head><body><h1>HELLO</h1></body></html>"));
// Uncomment the following line to create an invalid word document.
// MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes("<h1>HELLO</h1>"));
// Create alternative format import part.
AlternativeFormatImportPart formatImportPart =
mainDocPart.AddAlternativeFormatImportPart(
AlternativeFormatImportPartType.Html, altChunkId);
//ms.Seek(0, SeekOrigin.Begin);
// Feed HTML data into format import part (chunk).
formatImportPart.FeedData(ms);
AltChunk altChunk = new AltChunk();
altChunk.Id = altChunkId;
mainDocPart.Document.Body.Append(altChunk);
}
}
catch (Exception ex)
{
ex.ToString ();
}
}
推荐答案
添加HTML内容，因为Chunk应该可以工作，而且您已经差不多了.
Add HTML content as Chunk should work, and you are almost there.
如果我对问题的理解正确，那么此代码应该可以正常工作.
If I understand the question properly, this code should work.
//insert html content to H1 tag
using(WordprocessingDocument fDocx = WordprocessingDocument.Open(sDocxFile,true))
{
string sChunkID = "myhtmlID";
AlternativeFormatImportPart oChunk = fDocx.MainDocumentPart.AddAlternativeFormatImportPart(AlternativeFormatImportPartType.Html, sChunkID);
using(FileStream fs = File.Open(sHtml,FileMode.OpenOrCreate))
{
oChunk.FeedData(fs);
}
AltChunk oAltChunk = new AltChunk();
oAltChunk.Id =sChunkID ;
//insert html to the tag of 'H1' and remove H1.
Body body = fDocx.MainDocumentPart.Document.Body;
Paragraph theParagraph = body.Descendants<Paragraph>().Where(p => p.InnerText == "H1").FirstOrDefault();
theParagraph.InsertAfterSelf<AltChunk>(oAltChunk);
theParagraph.Remove();
fDocx.MainDocumentPart.Document.Save();
}
