OpenXML 替换word模板中的标签

最近的项目（MOSS项目）需要，用户需要根据word模板生成相关的word文档,具体需求是根据infopath表单中的内容和相关的模板生成一份word文档

着手做之前想想要是用word api操作的话，后台进程，多用户并发操作等等问题

看来还是用openxml来操作比较好，于是找了找资料，实现了这小小的功能

现在把代码贴出来跟大家分享下

使用openxml技术时，首先需要引用windowsbase.dll

部分常量

 

  const string documentRelationshipType = "http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument";
        const string strUri = "http://schemas.openxmlformats.org/wordprocessingml/2006/main";
        static List<string> bookmarkText;
        string bookmarkName;

 

该方法是将模板中所有标签都取出，并放到一个datatable中

 

void bindTable(string fileName)
        {
             

            dt = new DataTable();
            dt.Columns.Add("标签", typeof(string));
            dt.Columns.Add("内容", typeof(string));
            DataRow dr;

            Stream strm = null;
            PackagePart documentPart;
            Package package;
            
            
            using (SPSite site = new SPSite("http://ascentn-moss:8686/"))
            {
                SPWeb web = site.OpenWeb();
                strm = web.GetFile(fileName).OpenBinaryStream();
                documentPart = null;
                package = Package.Open(strm, FileMode.Open, FileAccess.ReadWrite);

                //FileStream fs = new FileStream(fileName, FileMode.OpenOrCreate);

                //PackagePart documentPart = null;
                //Package package = Package.Open(fileName, FileMode.Open, FileAccess.ReadWrite);
                //MessageBox.Show(strm.Length.ToString());
                // Package package = Package.Open(strm, FileMode.Open, FileAccess.ReadWrite);

                foreach (System.IO.Packaging.PackageRelationship documentRelationship in package.GetRelationshipsByType(documentRelationshipType))
                {
                    NameTable nt = new NameTable();
                    XmlNamespaceManager nsManager = new XmlNamespaceManager(nt);
                    nsManager.AddNamespace("w", strUri);

                    Uri documentUri = PackUriHelper.ResolvePartUri(new Uri("/", UriKind.Relative), documentRelationship.TargetUri);
                    documentPart = package.GetPart(documentUri);
                    XmlDocument xdoc = new XmlDocument();
                    xdoc.Load(documentPart.GetStream());
                    XmlNodeList nodeList = xdoc.SelectNodes("//w:bookmarkStart", nsManager);
                    foreach (XmlNode node in nodeList)
                    {
                        dr = dt.NewRow();

                        if (node.NextSibling.Name.ToString() == "w:bookmarkEnd")
                        {
                            bookmarkText = new List<string>();
                            bookmarkName = node.Attributes["w:name"].Value;
                            bookmarkText.Add(" ");

                            dr[0] = bookmarkName;
                            //dataGridView
                        }
                        else
                        {

                            bookmarkName = node.Attributes["w:name"].Value;
                            dr[0] = bookmarkName;
                            string bookmarkId = node.Attributes["w:id"].Value;
                            bookmarkText = new List<string>();

                            XmlNode nextParentNode = node.ParentNode;
                            XmlNode nodeIterate = node.NextSibling;

                            while (nodeIterate.Name.ToString() != "w:bookmarkEnd")
                            {
                                if (nodeIterate.Name.ToString() == "w:r")

                                    bookmarkText.Add(nodeIterate.InnerText);

                                nodeIterate = nodeIterate.NextSibling;
                                if (nodeIterate == null)
                                {
                                    if (nextParentNode.NextSibling.Attributes.Count != 0)
                                    {
                                        if ((nextParentNode.NextSibling.Attributes["w:id"].Value == bookmarkId))
                                        {
                                            nodeIterate = nextParentNode.NextSibling;
                                        }
                                    }

                                    else
                                    {
                                        nextParentNode = nextParentNode.NextSibling;

                                        nodeIterate = nextParentNode.FirstChild;
                                        bookmarkText.Add('\n' + nodeIterate.InnerText);

                                    }

                                }

                            }
                            //dic.Add(bookmarkName, bookmarkText);
                        }
                        dt.Rows.Add(dr);

                    }

                }
                package.Close();
            }

        }

 

接下来需要做的是用infopath中的相关节点去逐个替换标签内容

 

#region  处理标签

                string spUrl = (string)ds["SPServer"];

                APWS.Service apws = new APWS.Service();
                apws.Url = spUrl + "/spsws/Service.asmx";
                apws.Credentials = WFSystem.GetSystemUserCredential();

                System.IO.MemoryStream fileStream = new System.IO.MemoryStream();
                string newfilename = string.Empty;
                if(fileLocation.EndsWith("/"))
                    newfilename = fileLocation + fileName + template.Substring(template.LastIndexOf('.'));
                else
                    newfilename = fileLocation +"/"+ fileName + template.Substring(template.LastIndexOf('.'));

                apws.SPCopyFile(template, newfilename);

                fileStream.Write(apws.SPOpenBinary(newfilename), 0, apws.SPGetFileLenght(newfilename));

                originalDocPackage = Package.Open(fileStream, FileMode.Open, FileAccess.ReadWrite);

                foreach (PackageRelationship relationship in originalDocPackage.GetRelationshipsByType(documentRelationshipType))
                {
                    Uri documentUri = PackUriHelper.ResolvePartUri(new Uri("/", UriKind.Relative), relationship.TargetUri);
                    originalDocumentPart = originalDocPackage.GetPart(documentUri);

                    break;
                }

                originalXmlDocument = new XmlDocument();
                originalXmlDocument.Load(originalDocumentPart.GetStream());

                NameTable nt = new NameTable();
                XmlNamespaceManager xmlNamespaceManager = new XmlNamespaceManager(nt);
                xmlNamespaceManager.AddNamespace("w", strUri);

                #region 多个书签循环检索
                XmlNodeList bookmarknodeList = originalXmlDocument.SelectNodes("//w:bookmarkStart", xmlNamespaceManager);
                XmlNodeList bookmarknodeEndList = originalXmlDocument.SelectNodes("//w:bookmarkEnd", xmlNamespaceManager);
                XmlNode parentNodeOfBookMark;
                foreach (XmlNode xmlnode in bookmarknodeList)
                {
                    foreach (string columnName in hvalues.Keys)
                    {
                        if (xmlnode.Attributes["w:name"].Value == columnName)
                        {
                            if (xmlnode.NextSibling.Name == "w:r")
                            {
                                xmlnode.NextSibling.RemoveChild(xmlnode.NextSibling.LastChild);

                                XmlElement textElement = originalXmlDocument.CreateElement("w:t", strUri);
                                xmlnode.NextSibling.AppendChild(textElement);

                                XmlNode textNode = originalXmlDocument.CreateNode(XmlNodeType.Text, "w:t", strUri);
                                if(hvalues[columnName].ToString().EndsWith("T00:00:00"))
                                    textNode.Value = hvalues[columnName].ToString().Substring(0,hvalues[columnName].ToString().IndexOf('T'));
                                else
                                    textNode.Value = hvalues[columnName].ToString();
                                textElement.AppendChild(textNode);
                            }
                        }
                    }
                    parentNodeOfBookMark = xmlnode.ParentNode;
                    parentNodeOfBookMark.RemoveChild(xmlnode);
                }

                foreach (XmlNode xmlnode in bookmarknodeEndList)
                {
                    parentNodeOfBookMark = xmlnode.ParentNode;
                    parentNodeOfBookMark.RemoveChild(xmlnode);
                }
                #endregion

                //save document
                originalXmlDocument.Save(originalDocumentPart.GetStream(FileMode.Create, FileAccess.Write));


                byte[] bs = fileStream.ToArray();

                apws.SPSaveBinary(newfilename, bs);
                originalDocPackage.Close();
                #endregion
