Question

在调试时，新创建的元素的前缀为w :,但最后的Xmldoc会丢失它。

以下元素的结果InnerXML是： <altChunk id="FF_HTML" xmlns="http://schemas.openxmlformats.org/wordprocessingml/2006/main" />

预期结果为<w:altChunk r:id="FF_HTML"/>

private static XmlDocument prepareHTMLChunks(PackagePart partDocumentXML)
{
    XmlDocument doc = new XmlDocument();
    Stream xmlStream = partDocumentXML.GetStream();
    doc.Load(xmlStream);

    NameTable nt = new NameTable();
    nsManager = new XmlNamespaceManager(nt);            
    nsManager.AddNamespace("w", "http://schemas.openxmlformats.org/wordprocessingml/2006/main");

    XmlNodeList nodeList = doc.SelectNodes("//w:bookmarkStart", nsManager);
    foreach (XmlNode node in nodeList)
    {
        foreach (XmlAttribute attr in node.Attributes)
        {
            if (attr.Value.EndsWith("HTML"))
            {
                //XmlElement el = doc.CreateElement("w","w:altChunk",string.Empty);
                XmlElement el = doc.CreateElement("altChunk",nsManager.LookupNamespace("w"));


                XmlAttribute altChunkAttr = doc.CreateAttribute("r","id",string.Empty);
                altChunkAttr.Prefix = "r";
                altChunkAttr.Value = attr.Value;
                el.SetAttributeNode(altChunkAttr); 

                XmlNode nodeToReplace = node.ParentNode;                        

                XmlNode bodyNode = doc.SelectSingleNode("//w:body", nsManager);
                bodyNode.ReplaceChild(el, nodeToReplace);                          
            }                    
        }
    }            
    return doc;
}

Answer 1

前缀只是命名空间的别名。前缀本身并不重要。如果你愿意，你可以使用“前缀”作为前缀，这意味着完全相同的事情。

同样，完全相同的结果可能来自您在问题中显示的xmlns =“...”。这意味着与“w：”前缀完全相同，假设“w”别名为同一名称空间。

好的，我修好了：

        private static XmlDocument prepareHTMLChunks(PackagePart partDocumentXML)
    {

        XmlDocument _document = new XmlDocument();
        Stream xmlStream = partDocumentXML.GetStream();
        _document.Load(xmlStream);

        XmlNamespaceManager _ns = new XmlNamespaceManager(_document.NameTable);
        _ns.AddNamespace("w", "http://schemas.openxmlformats.org/wordprocessingml/2006/main");

        XmlNode _body = _document.SelectSingleNode("//w:body", _ns);

        foreach (XmlNode _node in _document.SelectNodes("//w:bookmarkStart", _ns))
        {
            foreach (XmlAttribute _attribute in _node.Attributes)
            {
                if (_attribute.Value.EndsWith("HTML"))
                {
                    XmlElement _element = _document.CreateElement("w", "altChunk", "http://schemas.openxmlformats.org/wordprocessingml/2006/main");
                    XmlAttribute _newAttr = _document.CreateAttribute("r", "id", "http://schemas.openxmlformats.org/officeDocument/2006/relationships");                        
                    _newAttr.Value = _attribute.Value;
                    _element.Attributes.Append(_newAttr);
                    _body.AppendChild(_element);                        
                }           
            }
        }            
        return _document;       
    }
