OpenXML在Word文档中查找变量并将其替换 [英] OpenXML Find Variables within Word doc and replace them

问题描述

我需要在文档中搜索<>中包含的字符串.因此，如果应用程序在文档中找到该变量，它将用DateTime.Today.ToShortDateString()替换该变量.例如:

I need to search a document for strings enclosed in <>. So if the application finds the variable within the document, it replaces that variable with DateTime.Today.ToShortDateString(). For instance:

string filename = "C:\\Temp\\" + appNum + "_ReceiptOfApplicationLtr.docx";
if (File.Exists((string)filename))
{
    using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(filename, true))
    {
        var body = wordDoc.MainDocumentPart.Document.Body;
        foreach (var text in body.Descendants<Text>())
        {
            if (text.Text == "<TodaysDate>")
            {
                text.Text = text.Text.Replace("<TodaysDate>", DateTime.Today.ToShortDateString());
            }
        }
        using (StreamWriter sw = new StreamWriter(wordDoc.MainDocumentPart.GetStream(FileMode.Create)))
        {
            sw.Write(filename);
        }
    }
}

当搜索后代文本时，它会找到第一个< ;，然后是TodaysDate，最后是>.问题是找不到字符串<TodaysDate>.有人可以帮我吗?

Well when it searches the Descendants Text, it finds the first <, then TodaysDate, finally >. The issue being it won't find the string <TodaysDate>. Can anyone help me out?

推荐答案

Open XML可以在同一运行中将文本存储在不同的text标记中.如果您是我，该怎么办就是找到存储字符串的Run并使用InnerText属性查找该运行中的所有文本. 例如:

Open XML can store text in different text tags inside the same run. What I would do if I were you is just find the Run where your string is stored and use the InnerText property to find all the text inside that run. For example:

Run runToFind = body.Descendants<Run>()
                    .FirstOrDefault(r => r.Innertext.Contains("<TodaysDate>");

然后您可以将Run替换为另一个:

Then you can replace the Run with another one:

runToFind.Parent.Replace(new Run(new Text(DateTime.Now.ToShortDateString())),runToFind);
