Question

我在C＃中使用以下功能来查找＆amp;使用open xml sdk替换word doc。

// To search and replace content in a document part.
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("Findme");
        docText = regexText.Replace(docText, "Before *&* After"); // <-- Replacement text

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

代码适用于大多数情况，但上面的情况替换文本有“＆amp;”打开文档时出错..

错误说：由于内容有问题，无法打开fileXYZ。细节：非法名称字符。

当我在替换字符串中使用"<w:br/>"在字符串末尾插入新行时，此错误也会持续存在。但我通过在"<w:br/> ".

之后添加空格来删除错误

PS：“替换文字”用注释表示。

// To search and replace content in a document part.

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("Findme");
        docText = regexText.Replace(docText, new System.Xml.Linq.XText("Before *&* After").ToString()); // when we replace string with "&" we need to convert like this

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

Word Doc。被开放的XML查找和损坏更换
