c#使用openXML创建word文档:XML解析错误(替换字符串包含空格时)

我正在尝试使用openXML在我的C#应用​​程序中使用word模板创建word文档。到目前为止,这是我的代码:

DirectoryInfo tempDir = new DirectoryInfo(Server.MapPath("~\\Files\\WordTemplates\\"));

DirectoryInfo docsDir = new DirectoryInfo(Server.MapPath("~\\Files\\FinanceDocuments\\"));

string ype = "test Merge"; //if ype string contains spaces then I get this error
string sourceFile = tempDir + "\\PaymentOrderTemplate.dotx";
string destinationFile = docsDir + "\\" + "PaymentOrder.doc";

// Create a copy of the template file and open the copy 
File.Copy(sourceFile, destinationFile, true);

// create key value pair, key represents words to be replace and 
//values represent values in document in place of keys.
Dictionary<string, string> keyValues = new Dictionary<string, string>();
keyValues.Add("ype", ype);                
SearchAndReplace(destinationFile, keyValues);
Process.Start(destinationFile);

SearchAndReplace功能:

public static void SearchAndReplace(string document, Dictionary<string, string> dict)
{
    using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(document, true))
    {
        string docText = null;

        using (StreamReader sr = new StreamReader(wordDoc.MainDocumentPart.GetStream()))
        {
            docText = sr.ReadToEnd();
        }

        foreach (KeyValuePair<string, string> item in dict)
        {
            Regex regexText = new Regex(item.Key);
            docText = regexText.Replace(docText, item.Value);
        }

        using (StreamWriter sw = new StreamWriter(
                  wordDoc.MainDocumentPart.GetStream(FileMode.Create)))
        {
            sw.Write(docText);
        }
    }
}

但是当我尝试打开导出的文件时出现此错误:

修改 我发现问题出现了,因为我在单词模板中使用了合并域。如果我使用纯文本它是有效的。但在这种情况下,它会很慢,因为它必须检查模板中的每个单词,如果匹配则替换它。是否有可能以另一种方式做到这一点?

1 个答案:

答案 0 :(得分:1)

免责声明:您似乎正在使用OpenXML SDK,因为您的代码看起来几乎与此处的代码完全相同:https://msdn.microsoft.com/en-us/library/bb508261(v=office.12).aspx - 我一生中从未使用过这个SDK而且我的基础这个答案基于一个有根据的猜测发生了什么

您在此Word文档上执行的操作似乎正在影响您不想要的文档部分。

我相信调用document.MainDocumentPart.GetStream()只是给你或多或少的原始直接访问文档的XML,然后你将它作为一个普通的xml文件处理,将其作为文本操作,并执行直接文本替换列表?我认为这可能是导致问题的原因,因为您打算编辑文档文本,但在过程中意外损坏xml节点结构

举个例子,这是一个简单的HTML文档:

<html>
 <head><title>Damage report</title></head>
 <body>
  <p>The soldier was shot once in the body and twice in the head</p>
 </body>
</html>

你决定运行一个发现/替换来使士兵被射杀的位置,更具体一点:

var html = File.ReadAllText(@"c:\my.html");
html = html.Replace("body", "chest");
html = html.Replace("head", "forehead");
File.WriteAllText(@"c:\my.html");

唯一的问题,你的文件现在已经毁了:

<html>
 <forehead><title>Damage report</title></forehead>
 <chest>
  <p>The soldier was shot once in the chest and twice in the forehead</p>
 </chest>
</html>

浏览器无法解析它(好吧,我认为它仍然有效,但它没有意义),因为替换操作破坏了一些东西。

您正在用"ype"替换"test Merge",但这似乎正在破坏"type"这个词的出现 - 这似乎很可能出现在XML属性中或元素名称 - 并将其转换为"ttest Merge"

要正确更改XML文档节点文本的内容,应将其从文本解析为XML文档对象模型表示,迭代节点,更改文本,并将整个事物重新序列化为xml文本。 Office SDK似乎提供了执行此操作的方法,因为您可以将文档视为类对象实例的集合,并说出此代码段(也来自MSDN):

// Create a Wordprocessing document. 
using (WordprocessingDocument myDoc = WordprocessingDocument.Create(docName, WordprocessingDocumentType.Document)) 
{ 
   // Add a new main document part. 
   MainDocumentPart mainPart = myDoc.AddMainDocumentPart(); 
   //Create DOM tree for simple document. 
   mainPart.Document = new Document(); 
   Body body = new Body(); 
   Paragraph p = new Paragraph(); 
   Run r = new Run(); 
   Text t = new Text("Hello World!"); 
   //Append elements appropriately. 
   r.Append(t); 
   p.Append(r); 
   body.Append(p); 
   mainPart.Document.Append(body); 
   // Save changes to the main document part. 
   mainPart.Document.Save(); 
}

您应该寻找另一种方法,而不是使用流/直接低级xml访问来访问文档元素。像这样的东西:
