使用Open Xml替换Word文档中的文本

标签: templates c#-4.0 openxml

我已经从word模板创建了一个docx文件,现在我正在访问复制的docx文件,并希望用某些其他数据替换某些文本。

我无法获得如何从doument主要部分访问文本的提示?

任何帮助都会很明显。

以下是我的代码。

private void CreateSampleWordDocument()
    {
        //string sourceFile = Path.Combine("D:\\GeneralLetter.dot");
        //string destinationFile = Path.Combine("D:\\New.doc");
        string sourceFile = Path.Combine("D:\\GeneralWelcomeLetter.docx");
        string destinationFile = Path.Combine("D:\\New.docx");
        try
        {
            // Create a copy of the template file and open the copy
            File.Copy(sourceFile, destinationFile, true);
            using (WordprocessingDocument document = WordprocessingDocument.Open(destinationFile, true))
            {
                // Change the document type to Document
                document.ChangeDocumentType(DocumentFormat.OpenXml.WordprocessingDocumentType.Document);
                //Get the Main Part of the document
                MainDocumentPart mainPart = document.MainDocumentPart;
                mainPart.Document.Save();
            }
        }
        catch
        {
        }
    }

现在如何找到某些文字并替换相同的文字? 我无法通过Link获得,所以一些代码提示会很明显。

为了让您了解如何操作,请尝试:

  using ( WordprocessingDocument doc =
                    WordprocessingDocument.Open(@"yourpath\testdocument.docx", true))
            {
                var body = doc.MainDocumentPart.Document.Body;
                var paras = body.Elements<Paragraph>();

                foreach (var para in paras)
                {
                    foreach (var run in para.Elements<Run>())
                    {
                        foreach (var text in run.Elements<Text>())
                        {
                            if (text.Text.Contains("text-to-replace"))
                            {
                                text.Text = text.Text.Replace("text-to-replace", "replaced-text");
                            }
                        }
                    }
                }
            }
        }

请注意,文字区分大小写。替换后不会更改文本格式。希望这会对你有所帮助。

除了Flowerking的回答:

当您的Word文件中包含文本框时,他的解决方案将无效。因为textbox具有TextBoxContent元素,所以它不会出现在Run s的foreach循环中。

但写作时

using ( WordprocessingDocument doc =
                    WordprocessingDocument.Open(@"yourpath\testdocument.docx", true))
{
    var document = doc.MainDocumentPart.Document

    foreach (var text in document.Descendants<Text>()) // <<< Here
    {
        if (text.Text.Contains("text-to-replace"))
        {
            text.Text = text.Text.Replace("text-to-replace", "replaced-text");
        }
    } 
}

它将循环文档中的所有文本(无论是否在文本框中),因此它将替换文本。

请注意,如果文本在运行或文本框之间拆分,这也不会起作用。对于这些情况,您需要更好的解决方案。

也许这个解决方案更容易:
1. StreamReader读取所有文本,
2.使用Regex大小写不敏感地替换新文本而不是旧文本 3. StreamWriter再次将修改后的文本写入文档。

 using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(document, true))
{
    string docText = null;
    using (StreamReader sr = new StreamReader(wordDoc.MainDocumentPart.GetStream()))
        docText = sr.ReadToEnd();

    foreach (var t in findesReplaces)
        docText = new Regex(findText, RegexOptions.IgnoreCase).Replace(docText, replaceText);

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

答案 3 :(得分:1)

我正在测试这个用于生成文档,但我的占位符被拆分到运行和文本节点。我不想将整个文档作为正则表达式查找/替换的单个字符串加载,所以我使用了 OpenXml api。我的想法是:

  1. 清理占位符节点作为对文档的一次性操作
  2. 每次生成时按节点值查找/替换,现在源是干净的。

测试表明占位符被拆分为运行和文本节点,而不是段落。我还发现后续的占位符没有共享文本节点,所以我没有处理。占位符遵循模式 {{placeholder_name}}

首先,我需要获取段落中的所有文本节点(根据@sertsedat):

    var nodes = paragraph.Descendants<Text>();

测试表明,此函数保留了顺序,这非常适合我的用例,因为我可以遍历集合以查找开始/停止指示符,并将那些属于我的占位符的节点分组。

分组函数在文本节点值中查找 {{}},以标识属于占位符的一部分并应删除的节点,以及应忽略的其他节点。

一旦找到一个节点的开始,所有后续节点,包括终止点,都需要被删除(通过添加到 TextNodes 列表来标记),这些节点的值包含在占位符 StringBuilder 以及第一个/最后一个节点的任何不属于占位符的文本部分也需要保存(因此是字符串属性)。发现新占位符时或在序列末尾时任何不完整的组都应引发错误。

最后,我用分组来更新原始文档

foreach (var placeholder in GroupPlaceholders(paragraph.Descendants<Text>()))
{
    var firstTextNode = placeholder.TextNodes[0];
    if (placeholder.PrecedingText != null)
    {
        firstTextNode.Parent.InsertBefore(new Text(placeholder.PrecedingText), firstTextNode);
    }
    firstTextNode.Parent.InsertBefore(placeholder.PlaceholderText, firstTextNode);
    if (placeholder.SubsequentText != null)
    {
        firstTextNode.Parent.InsertBefore(new Text(placeholder.SubsequentText), firstTextNode);
    }
    foreach (var textNode in placeholder.TextNodes) {
        textNode.Remove();                      
    }
}

如果您要查找的文本位于括号之间,Word会在多次运行中拆分文本...;

搜索文本(ienumerable(of text))

for (int i = 0; i <= SearchIn.Count - 1; i++) {

    if (!(i + 2 > SearchIn.Count - 1)) {
        Text TXT = SearchIn(i);
        Text TXT1 = SearchIn(i + 1);
        Text TXT2 = SearchIn(i + 2);

        if (Strings.Trim(TXT.Text) == "[" & Strings.Trim(TXT2.Text) == "]") {
            TXT1.Text = TXT.Text + TXT1.Text + TXT2.Text;

            TXT.Text = "";
            TXT2.Text = "";
        }
    }
}

            }

            return wordMatchedPhrases;

        }

    }
}

以及易于使用的示例:

public void EditWordDocument(UserContents userContents)
        {
            string filePath = Path.Combine(userContents.PathOnDisk, userContents.FileName);
            WordDocumentService wordDocumentService = new WordDocumentService();
            if (userContents.ContentType.Contains("word") && File.Exists(filePath))
            {
                string saveAs = "modifiedTechWord.docx";
                //
                using (WordprocessingDocument doc = WordprocessingDocument.Open(filePath, true)) //open source word file
                {
                    Document document = doc.MainDocumentPart.Document;
                    OpenXmlPackage res = doc.SaveAs(Path.Combine(userContents.PathOnDisk, saveAs)); // copy it
                    res.Close();
                }
                using (WordprocessingDocument doc = WordprocessingDocument.Open(Path.Combine(userContents.PathOnDisk, saveAs), true)) // open copy
                {
                    string replaceWhat = "{transform:CandidateFio}";
                    string replaceFor = "ReplaceToFio";
                    var result = wordDocumentService.ReplaceStringInWordDocumennt(doc, replaceWhat, replaceFor); //replace words in copy
                }
            }
        }

到目前为止,我发现最简单,最准确的方法是使用Open-Xml-PowerTools。就个人而言,我使用dotnet core,所以我使用this nuget package

using OpenXmlPowerTools;
// ...

protected byte[] SearchAndReplace(byte[] file, IDictionary<string, string> translations)
{
    WmlDocument doc = new WmlDocument(file.Length.ToString(), file);

    foreach (var translation in translations)
        doc = doc.SearchAndReplace(translation.Key, translation.Value, true);

    return doc.DocumentByteArray;
}

使用示例:

var templateDoc = File.ReadAllBytes("templateDoc.docx");
var generatedDoc = SearchAndReplace(templateDoc, new Dictionary<string, string>(){
    {"text-to-replace-1", "replaced-text-1"},
    {"text-to-replace-2", "replaced-text-2"},
});
File.WriteAllBytes("generatedDoc.docx", generatedDoc);

here是来自msdn的解决方案。

来自那里的例子:

public static void SearchAndReplace(string document)
{
    using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(document, true))
    {
        string docText = null;
        using (StreamReader sr = new StreamReader(wordDoc.MainDocumentPart.GetStream()))
        {
            docText = sr.ReadToEnd();
        }

        Regex regexText = new Regex("Hello world!");
        docText = regexText.Replace(docText, "Hi Everyone!");

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