Question

我找不到任何替换书签内容的工作代码示例。代码应该能够处理大小写替换空书签和用预先存在的内容替换书签。

例如：如果我在Word文档中有此文本：

“以下期间之间会出现Bookmark1 ..在下一期间会有Bookmark2 ..”

我希望在第一个句点之间插入文本“BM1”，在下一个句点之间插入“BM2”。

第一次更换后，正确插入替换件。

但是在下一次替换运行之后，Bookmark1之后的行上的所有文本都被删除，然后插入了Bookmark2的替换。

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();
        }
    }

我已经花了很长时间寻找一般解决方案。任何帮助表示赞赏！ -Victor

当代码放在字段/ formtext（灰色框）中时，此代码可以正常工作。

    private static void SetNewContents(wd.BookmarkStart bookmarkStart, string text)
    {
        if (bookmarkStart.ColumnFirst != null) return;

        var itemsToRemove = new List<OpenXmlElement>();

        var nextSibling = bookmarkStart.NextSibling();

        while (nextSibling != null)
        {

            if (IsEndBookmark(nextSibling, bookmarkStart))
                break;

            if (nextSibling is wd.Run)
                itemsToRemove.Add(nextSibling);

            nextSibling = nextSibling.NextSibling();
        }

        foreach (var item in itemsToRemove)
        {
            item.RemoveAllChildren();
            item.Remove();
        }

        bookmarkStart.Parent.InsertAfter(new wd.Run(new wd.Text(text)), bookmarkStart);
    }

也许这可以帮助您第一：删除书签内容第二：找到bookMark =>插入值

        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
                }
            }
    public static void RemoveBookMarkContent(WordprocessingDocument doc, string bmName)
            {
                BookmarkStart bmStart = findBookMarkStart(doc, bmName);
                BookmarkEnd bmEnd = findBookMarkEnd(doc, bmStart.Id);
                while (true)
                {
                    var run = bmStart.NextSibling();
                    if (run == null)
                    {
                        break;
                    }
                    if (run is BookmarkEnd && (BookmarkEnd)run == bmEnd)
                    {
                        break;
                    }

                    run.Remove();
                }
            }
private static BookmarkStart findBookMarkStart(WordprocessingDocument doc, string bmName)
        {
            foreach (var footer in doc.MainDocumentPart.FooterParts)
            {
                foreach (var inst in footer.Footer.Descendants<BookmarkStart>())
                {
                    if (inst.Name == bmName)
                    {
                        return inst;
                    }
                }
            }

            foreach (var header in doc.MainDocumentPart.HeaderParts)
            {
                foreach (var inst in header.Header.Descendants<BookmarkStart>())
                {
                    if (inst.Name == bmName)
                    {
                        return inst;
                    }
                }
            }
            foreach (var inst in doc.MainDocumentPart.RootElement.Descendants<BookmarkStart>())
            {
                if (inst is BookmarkStart)
                {
                    if (inst.Name == bmName)
                    {

                    }
                }
            }

            return null;
