我试图操纵在C＃中的Word 2007文档的XML。我设法查找和处理，我希望节点，但现在我似乎无法弄清楚如何救回来。下面是我想：

I am trying to manipulate the XML of a Word 2007 document in C#. I have managed to find and manipulate the node that I want but now I can't seem to figure out how to save it back. Here is what I am trying:

// Open the document  from memoryStream
Package pkgFile = Package.Open(memoryStream, FileMode.Open, FileAccess.ReadWrite);
PackageRelationshipCollection pkgrcOfficeDocument = pkgFile.GetRelationshipsByType(strRelRoot);

foreach (PackageRelationship pkgr in pkgrcOfficeDocument)
{
    if (pkgr.SourceUri.OriginalString == "/")
    {
        Uri uriData = new Uri("/word/document.xml", UriKind.Relative);

        PackagePart pkgprtData = pkgFile.GetPart(uriData);

        XmlDocument doc = new XmlDocument();
        doc.Load(pkgprtData.GetStream());

        NameTable nt = new NameTable();
        XmlNamespaceManager nsManager = new XmlNamespaceManager(nt);
        nsManager.AddNamespace("w", nsUri);

        XmlNodeList nodes = doc.SelectNodes("//w:body/w:p/w:r/w:t", nsManager);

        foreach (XmlNode node in nodes)
        {
            if (node.InnerText == "{{TextToChange}}")
            {
                node.InnerText = "success";
            }
        }


        if (pkgFile.PartExists(uriData))
        {
            // Delete template "/customXML/item1.xml" part
            pkgFile.DeletePart(uriData);
        }
        PackagePart newPkgprtData = pkgFile.CreatePart(uriData, "application/xml");
        StreamWriter partWrtr = new StreamWriter(newPkgprtData.GetStream(FileMode.Create, FileAccess.Write));

        doc.Save(partWrtr);
        partWrtr.Close();
    }
}   

pkgFile.Close();

我得到的错误记忆流不可扩展。任何想法？

I get the error 'Memory stream is not expandable'. Any ideas?

推荐答案

我会建议你使用Open XML SDK ，而不是由黑客自己的格式。

I would recommend that you use Open XML SDK instead of hacking the format by yourself.
