使用openxmlsdk替换Word文件中的书签文本

以下是我用你们作为灵感的方法:

  IDictionary<String, BookmarkStart> bookmarkMap = 
      new Dictionary<String, BookmarkStart>();

  foreach (BookmarkStart bookmarkStart in file.MainDocumentPart.RootElement.Descendants<BookmarkStart>())
  {
      bookmarkMap[bookmarkStart.Name] = bookmarkStart;
  }

  foreach (BookmarkStart bookmarkStart in bookmarkMap.Values)
  {
      Run bookmarkText = bookmarkStart.NextSibling<Run>();
      if (bookmarkText != null)
      {
          bookmarkText.GetFirstChild<Text>().Text = "blah";
      }
  }

public static void InsertIntoBookmark(BookmarkStart bookmarkStart, string text)
{
    OpenXmlElement elem = bookmarkStart.NextSibling();

    while (elem != null && !(elem is BookmarkEnd))
    {
        OpenXmlElement nextElem = elem.NextSibling();
        elem.Remove();
        elem = nextElem;
    }

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

首先,删除开始和结束之间的现有内容。然后直接在开始后面(在结束之前)添加一个新的运行。

但是,不确定书签是在打开时在另一节中关闭的,还是在不同的表单元格中关闭的,等等。。

对我来说现在已经足够了。

    Public static void ReplaceBookmarkParagraphs(WordprocessingDocument doc, string bookmark, string text)
    {
        //Find all Paragraph with 'BookmarkStart' 
        var t = (from el in doc.MainDocumentPart.RootElement.Descendants<BookmarkStart>()
                 where (el.Name == bookmark) &&
                 (el.NextSibling<Run>() != null)
                 select el).First();
        //Take ID value
        var val = t.Id.Value;
        //Find the next sibling 'text'
        OpenXmlElement next = t.NextSibling<Run>();
        //Set text value
        next.GetFirstChild<Text>().Text = text;

        //Delete all bookmarkEnd node, until the same ID
        deleteElement(next.GetFirstChild<Text>().Parent, next.GetFirstChild<Text>().NextSibling(), val, true);
    }

之后,我打电话给:

Public static bool deleteElement(OpenXmlElement parentElement, OpenXmlElement elem, string id, bool seekParent)
{
    bool found = false;

    //Loop until I find BookmarkEnd or null element
    while (!found && elem != null && (!(elem is BookmarkEnd) || (((BookmarkEnd)elem).Id.Value != id)))
    {
        if (elem.ChildElements != null && elem.ChildElements.Count > 0)
        {
            found = deleteElement(elem, elem.FirstChild, id, false);
        }

        if (!found)
        {
            OpenXmlElement nextElem = elem.NextSibling();
            elem.Remove();
            elem = nextElem;
        }
    }

    if (!found)
    {
        if (elem == null)
        {
            if (!(parentElement is Body) && seekParent)
            {
                //Try to find bookmarkEnd in Sibling nodes
                found = deleteElement(parentElement.Parent, parentElement.NextSibling(), id, true);
            }
        }
        else
        {
            if (elem is BookmarkEnd && ((BookmarkEnd)elem).Id.Value == id)
            {
                found = true;
            }
        }
    }

    return found;
}

如果你没有空书签,这段代码就可以正常工作。 我希望它能帮助别人。

我10分钟前就知道了,所以请原谅代码的黑客性质。

private static Dictionary<string, BookmarkEnd> FindBookmarks(OpenXmlElement documentPart, Dictionary<string, BookmarkEnd> results = null, Dictionary<string, string> unmatched = null )
{
    results = results ?? new Dictionary<string, BookmarkEnd>();
    unmatched = unmatched ?? new Dictionary<string,string>();

    foreach (var child in documentPart.Elements())
    {
        if (child is BookmarkStart)
        {
            var bStart = child as BookmarkStart;
            unmatched.Add(bStart.Id, bStart.Name);
        }

        if (child is BookmarkEnd)
        {
            var bEnd = child as BookmarkEnd;
            foreach (var orphanName in unmatched)
            {
                if (bEnd.Id == orphanName.Key)
                    results.Add(orphanName.Value, bEnd);
            }
        }

        FindBookmarks(child, results, unmatched);
    }

    return results;
}

var bookMarks = FindBookmarks(doc.MainDocumentPart.Document);

foreach( var end in bookMarks )
{
    var textElement = new Text("asdfasdf");
    var runElement = new Run(textElement);

    end.Value.InsertAfterSelf(runElement);
}

从我可以看出,插入和替换书签看起来比较困难。当我使用InsertAt而不是InsertIntoSelf时,我得到了:“非复合元素没有子元素。”

我从答案中提取了代码,在特殊情况下有几个问题:

3. 书签可以是空的,所以BookmarkStart直接跟在BookmarkEnd后面,在这种情况下,您只需调用 bookmarkStart.Parent.InsertAfter(new Run(new Text("Hello World")), bookmarkStart)
4. 另外,书签可以包含许多文本元素,因此您可能需要删除所有其他元素,否则可能会替换部分书签,而其他后续部分将保留。
5. 我不确定我的最后一次破解是否有必要,因为我不知道OpenXML的所有限制,但是在发现了前面的4个之后,我也不再相信会有Run的兄弟,文本的孩子。因此,我只需查看我所有的兄弟姐妹(直到BookmarEnd与BookmarkStart具有相同的ID),然后检查所有的孩子,直到找到任何文本。-如果有必要的话,也许对OpenXML有更多经验的人可以回答?

下面是我如何使用VB在bookmarkStart和BookmarkEnd之间添加/替换文本。

<w:bookmarkStart w:name="forbund_kort" w:id="0" /> 
        - <w:r>
          <w:t>forbund_kort</w:t> 
          </w:r>
<w:bookmarkEnd w:id="0" />

公认的答案和其他一些答案假设书签在文档结构中的位置。下面是我的C代码,它可以处理替换跨越多个段落的书签 和 正确替换不以段落边界开始和结束的书签。仍然不完美,但更接近。。。希望有用。编辑,如果你找到更多的方法来改善它!

    private static void ReplaceBookmarkParagraphs(MainDocumentPart doc, string bookmark, IEnumerable<OpenXmlElement> paras) {
        var start = doc.Document.Descendants<BookmarkStart>().Where(x => x.Name == bookmark).First();
        var end = doc.Document.Descendants<BookmarkEnd>().Where(x => x.Id.Value == start.Id.Value).First();
        OpenXmlElement current = start;
        var done = false;

        while ( !done && current != null ) {
            OpenXmlElement next;
            next = current.NextSibling();

            if ( next == null ) {
                var parentNext = current.Parent.NextSibling();
                while ( !parentNext.HasChildren ) {
                    var toRemove = parentNext;
                    parentNext = parentNext.NextSibling();
                    toRemove.Remove();
                }
                next = current.Parent.NextSibling().FirstChild;

                current.Parent.Remove();
            }

            if ( next is BookmarkEnd ) {
                BookmarkEnd maybeEnd = (BookmarkEnd)next;
                if ( maybeEnd.Id.Value == start.Id.Value ) {
                    done = true;
                }
            }
            if ( current != start ) {
                current.Remove();
            }

            current = next;
        }

        foreach ( var p in paras ) {
            end.Parent.InsertBeforeSelf(p);
        }
    }

以下是我的结论-不是100%完美,但适用于简单的书签和简单的文本插入:

private void FillBookmarksUsingOpenXml(string sourceDoc, string destDoc, Dictionary<string, string> bookmarkData)
    {
        string wordmlNamespace = "http://schemas.openxmlformats.org/wordprocessingml/2006/main";
        // Make a copy of the template file.
        File.Copy(sourceDoc, destDoc, true);

        //Open the document as an Open XML package and extract the main document part.
        using (WordprocessingDocument wordPackage = WordprocessingDocument.Open(destDoc, true))
        {
            MainDocumentPart part = wordPackage.MainDocumentPart;

            //Setup the namespace manager so you can perform XPath queries 
            //to search for bookmarks in the part.
            NameTable nt = new NameTable();
            XmlNamespaceManager nsManager = new XmlNamespaceManager(nt);
            nsManager.AddNamespace("w", wordmlNamespace);

            //Load the part's XML into an XmlDocument instance.
            XmlDocument xmlDoc = new XmlDocument(nt);
            xmlDoc.Load(part.GetStream());

            //Iterate through the bookmarks.
            foreach (KeyValuePair<string, string> bookmarkDataVal in bookmarkData)
            {
                var bookmarks = from bm in part.Document.Body.Descendants<BookmarkStart>()
                          select bm;

                foreach (var bookmark in bookmarks)
                {
                    if (bookmark.Name == bookmarkDataVal.Key)
                    {
                        Run bookmarkText = bookmark.NextSibling<Run>();
                        if (bookmarkText != null)  // if the bookmark has text replace it
                        {
                            bookmarkText.GetFirstChild<Text>().Text = bookmarkDataVal.Value;
                        }
                        else  // otherwise append new text immediately after it
                        {
                            var parent = bookmark.Parent;   // bookmark's parent element

                            Text text = new Text(bookmarkDataVal.Value);
                            Run run = new Run(new RunProperties());
                            run.Append(text);
                            // insert after bookmark parent
                            parent.Append(run);
                        }

                        //bk.Remove();    // we don't want the bookmark anymore
                    }
                }
            }

            //Write the changes back to the document part.
            xmlDoc.Save(wordPackage.MainDocumentPart.GetStream(FileMode.Create));
        }
    }
