使用 Sharepoint Word Automation 进行文本替换 [英] Using Sharepoint Word Automation to do a text replace

问题描述

我正在使用 sharepoint 2010，我想要做的是使用 word 文档模板，替换几个关键词(例如:用 id 替换 ##ClientID##客户端)并使用特定名称将其保存在 sharepoint 上的库中.

I am working with sharepoint 2010, what I am trying to do is take a word document template, do a replace on a few key words (ex: replace ##ClientID## with the id of the client) and save it with a specific name in a library on sharepoint.

我已经想出了如何在本地计算机上使用 word interop 执行此操作，但是 word interop 库并非旨在作为服务运行.然后我发现 Word Automation Services 似乎可以做我需要做的事情.但是，我在互联网上找到的每个示例(包括 SO 上的此处)都只是使用 Microsoft.Office.Word.Server.Conversions 命名空间的如何从 Word 文档转换为 xxx".我还没有找到关于如何使用 Microsoft.Office.Word.Server.Service 命名空间对文档进行查找和替换的示例.MSDN 非常缺乏如何使用这些类，我不知道从哪里开始使用它.

I have figured out how to do this on a local computer with word interop, however the word interop library is not designed to be run as a service. I then discovered Word Automation Services which appear to do what I need to do. However every example I find on the internet (including here on SO) is just "How to convert from a word document to xxx" using the Microsoft.Office.Word.Server.Conversions namespace. I have yet to find a example on how to use the Microsoft.Office.Word.Server.Service namespace to do a find and replace on a document. The MSDN is very lacking on how to use the classes and I do not know where to begin using it.

不能使用这些服务来做我想做的事吗?如果可以的话，有人能指出我正确的方向来做我想做的事吗?

Is it not possible to use the services to do what I want to? If it can be done can someone point me in the right direction to do what I want to do?

推荐答案

看来 Word Automation Services 不是我想用的来做我想做的，我需要的是 Open XML SDK.

It appears that Word Automation Services is not what I want to use to do what I want to do, what I need is Open XML SDK.

更新:这是有关如何对文档进行替换的代码，在我的文本中，我想替换富文本框中的位置.所以这就是我查看 SdtRun 内部的原因.

UPDATE: here is the code on how to do a replace on the document, in my the text I wanted to replace where in rich text boxes. so that is why I am looking inside SdtRun.

public FileDetails GetOrGenerateChecklist(string PracticeName, string ContractID, string EducationDate, string MainContactInfo, string Address)
{
    if (String.IsNullOrEmpty(PracticeName) || String.IsNullOrEmpty(ContractID))
        return null;
    SPWeb web = SPContext.Current.Web;

    SPDocumentLibrary list = (SPDocumentLibrary)web.Lists["Educator Checklists"];
    var templetAddr = String.Concat(web.Url, '/', list.DocumentTemplateUrl);
    SPQuery query = new SPQuery();
    query.Query = string.Concat(
                            "<Where><Eq>",
                                "<FieldRef Name='FileLeafRef'/>",
                                "<Value Type='File'>", PracticeName, " - ", ContractID, ".docx</Value>",
                            "</Eq></Where>");
    var items = list.GetItems(query);

    //if document exists return existing document.
    if (items.Count > 0)
        return new FileDetails() { Address = String.Concat(web.Url, "/Educator Checklists/", PracticeName, " - ", ContractID, ".docx"), LastModified = (DateTime)items[0]["Modified"]};

    //Begin transforming form template to document.
    MemoryStream documentStream;

    //copy the stream to memory
    using (Stream tplStream = web.GetFile(templetAddr).OpenBinaryStream())
    {
        documentStream = new MemoryStream((int)tplStream.Length);
        CopyStream(tplStream, documentStream);
        documentStream.Position = 0L;
    }

    using (WordprocessingDocument template = WordprocessingDocument.Open(documentStream, true))
    {
        template.ChangeDocumentType(DocumentFormat.OpenXml.WordprocessingDocumentType.Document);
        MainDocumentPart mainPart = template.MainDocumentPart;
        mainPart.DocumentSettingsPart.AddExternalRelationship(
            "http://schemas.openxmlformats.org/officeDocument/2006/relationships/attachedTemplate",
            new Uri(templetAddr, UriKind.Absolute));

        ReplaceText(mainPart, "#PracticeName#", PracticeName);
        if(!String.IsNullOrEmpty(EducationDate))
            ReplaceText(mainPart, "#EducationDate#", EducationDate);
        if(!String.IsNullOrEmpty(MainContactInfo))
            ReplaceText(mainPart, "#MainContactInfo#", MainContactInfo);
        if(!String.IsNullOrEmpty(Address))
            ReplaceText(mainPart, "#Address#", Address);
    }
    documentStream.Position = 0L;
    try
    {
        list.RootFolder.Files.Add(String.Concat(PracticeName, " - ", ContractID, ".docx"), documentStream);
    }
    catch(SPException)
    {
        return null;
    }

    return new FileDetails() { Address = String.Concat(web.Url, "/Educator Checklists/", PracticeName, " - ", ContractID, ".docx"), LastModified = DateTime.Now };


}

private static void CopyStream(Stream source, Stream destination, int bufferSize = 0x1000)
{
    int num;
    byte[] buffer = new byte[bufferSize];
    while ((num = source.Read(buffer, 0, buffer.Length)) != 0)
    {
        destination.Write(buffer, 0, num);
    }

}

private static void ReplaceText(MainDocumentPart docPart, string match, string value)
{
    if (value == null)
        value = String.Empty;
    var sdtr = docPart.Document.Descendants<SdtRun>();
    foreach (var sdt in sdtr)
    {
        if (sdt.InnerText == match)
        {

            Text txt = new Text(value);
            //using the sdt.FirstChild.FirstChild.CloneNode(true) will copy the text formatting of the old text.
            var newtext = new SdtContentRun(new Run(sdt.FirstChild.FirstChild.CloneNode(true), txt));
            sdt.SdtContentRun.RemoveAllChildren();
            sdt.SdtContentRun.InsertAt(newtext, 0);
        }
    }
}
