使用OpenXml替换Word中的书签内容 [英] Replace bookmark contents in Word using OpenXml

问题描述

我找不到用于替换书签内容的任何有效代码示例.该代码应该能够处理替换空书签和用现有内容替换书签的情况.

I can't find any working code examples for replacing bookmark contents. The code should be able to handle both the case replace empty bookmark and replace bookmark with preexisting content.

例如:如果我在Word文档中有此文本:

For example: If I have this text in a Word document:

在以下两个期间之间是Bookmark1.在下一个期间之间是Bookmark2."

我想在第一个句点之间插入文本"BM1"，在下一个句点之间插入"BM2".

and I want to insert the text "BM1" between the first periods, and "BM2" between the next.

第一次替换运行后，替换正确插入.

After the first replacement run, the replacements are inserted correctly.

但是在下一次替换运行之后，将删除Bookmark1之后的行上的所有文本，然后插入对Bookmark2的替换.

But after the next replacement run, all of the text on the line after Bookmark1 gets deleted, and then the replacement for Bookmark2 gets inserted.

这是我的C#代码:

    var doc = WordprocessingDocument.Open(@"file.docx", true);

    public static Dictionary<string, wd.BookmarkStart> FindAllBookmarksInWordFile(WordprocessingDocument file)
    {
        var bookmarkMap = new Dictionary<String, wd.BookmarkStart>();


        foreach (var headerPart in file.MainDocumentPart.HeaderParts)
        {
            foreach (var bookmarkStart in headerPart.RootElement.Descendants<wd.BookmarkStart>())
            {
                if (!bookmarkStart.Name.ToString().StartsWith("_"))
                    bookmarkMap[bookmarkStart.Name] = bookmarkStart;
            }
        }

        foreach (var bookmarkStart in file.MainDocumentPart.RootElement.Descendants<wd.BookmarkStart>())
        {
            if (!bookmarkStart.Name.ToString().StartsWith("_"))
                bookmarkMap[bookmarkStart.Name] = bookmarkStart;
        }


        return bookmarkMap;
    }
    /*extension methods*/
    public static bool IsEndBookmark(this OpenXmlElement element, BookmarkStart startBookmark)
    {
        return IsEndBookmark(element as BookmarkEnd, startBookmark);
    }

    public static bool IsEndBookmark(this BookmarkEnd endBookmark, BookmarkStart startBookmark)
    {
        if (endBookmark == null)
            return false;

        return endBookmark.Id.Value == startBookmark.Id.Value;
    }
    /* end of extension methods */

    public static void SetText(BookmarkStart bookmark, string value)
    {
        RemoveAllTexts(bookmark);

        bookmark.Parent.InsertAfter(new Run(new Text(value)), bookmark);
    }

    private static void RemoveAllTexts(BookmarkStart bookmark)
    {
        if (bookmark.ColumnFirst != null) return;

        var nextSibling = bookmark.NextSibling();

        while (nextSibling != null)
        {
            if (nextSibling.IsEndBookmark(bookmark) || nextSibling.GetType() == typeof(BookmarkStart))
                break;

            foreach (var item in nextSibling.Descendants<Text>())
            {
                item.Remove();
            }
            nextSibling = nextSibling.NextSibling();
        }
    }

很长一段时间以来，我一直在寻找一种通用的解决方案. 任何帮助表示赞赏！ -维克多

也许可以帮助您 第一:删除书签内容 第二:找到书签=>插入值

Maybe this can help you first:delete bookmarkContent second:find bookMark => insert value

        public static void InsertTest1(WordprocessingDocument doc, string bookMark, string txt)
            {
                try
                {
                    RemoveBookMarkContent(doc, bookMark);

                    MainDocumentPart mainPart = doc.MainDocumentPart;

                    BookmarkStart bmStart = findBookMarkStart(doc, bookMark);
                    if (bmStart == null)
                    {
                        return;
                    }
                    Run run = new Run(new Text(txt));
                    bmStart.Parent.InsertAfter<Run>(run, bmStart);
                }
                catch (Exception c)
                {
                    //not Exception
