Question

使用ASPOSE.WORDS（.Net）我试图将两个RTF文档合并到另一个中。

我想让整个文档替换第二个文档中的一串文本。

到目前为止，我已经能够连接两个文件，但这并不是我所追求的。

const string BOOKMARK = @"UNIQUE_STRING"; //UNUSED at the moment

Aspose.Words.Document dWords = new Aspose.Words.Document(@"C:\RTFM\test1.rtf", LoadFormat.Rtf,"");
Aspose.Words.Document dWords2 = new Aspose.Words.Document(@"C:\RTFM\test2.rtf", LoadFormat.Rtf, "");

ImportFormatMode mode = ImportFormatMode.KeepSourceFormatting;

foreach (Section srcSection in dWords2)
{
    Node dstSection = dWords.ImportNode(srcSection, true, mode);
    dWords.AppendChild(dstSection);
}

dWords.Save(@"C:\output.rtf")

Answer 1

在您的情况下，您需要实现IReplacingCallback接口以查找文本并将其替换为文档（rtf）。使用以下代码示例来满足您的要求。

Document doc = new Document(MyDir + "input.rtf");

FindandInsertDocument replacedoc = new FindandInsertDocument(MyDir + "document to be inserted.rtf");

doc.Range.Replace(new Regex("text which needs to be replaced with document"), replacedoc, false); 

doc.Save(MyDir + "Out.rtf");

FindandInsertDocument类：

private class FindandInsertDocument : IReplacingCallback
{
    private String path;

    public FindandInsertDocument(String documentpath)
    {
        path = documentpath;
    }

    /// <summary>
    /// This method is called by the Aspose.Words find and replace engine for each match.
    /// </summary>
    ReplaceAction IReplacingCallback.Replacing(ReplacingArgs e)
    {
        // This is a Run node that contains either the beginning or the complete match.
        Node currentNode = e.MatchNode;

        // The first (and may be the only) run can contain text before the match,
        // in this case it is necessary to split the run.
        if (e.MatchOffset > 0)
            currentNode = SplitRun((Run)currentNode, e.MatchOffset);

        // This array is used to store all nodes of the match for further removing.
        ArrayList runs = new ArrayList();

        // Find all runs that contain parts of the match string.
        int remainingLength = e.Match.Value.Length;
        while (
            (remainingLength > 0) &&
            (currentNode != null) &&
            (currentNode.GetText().Length <= remainingLength))
        {
            runs.Add(currentNode);
            remainingLength = remainingLength - currentNode.GetText().Length;

            // Select the next Run node.
            // Have to loop because there could be other nodes such as BookmarkStart etc.
            do
            {
                currentNode = currentNode.NextSibling;
            }
            while ((currentNode != null) && (currentNode.NodeType != NodeType.Run));
        }

        // Split the last run that contains the match if there is any text left.
        if ((currentNode != null) && (remainingLength > 0))
        {
            SplitRun((Run)currentNode, remainingLength);
            runs.Add(currentNode);
        }

        // Create Document Builder and insert document
        DocumentBuilder builder = new DocumentBuilder(e.MatchNode.Document as Document);
        builder.MoveTo((Run)runs[runs.Count - 1]);

        Document doc = new Document(path);
        builder.InsertDocument(doc, ImportFormatMode.KeepSourceFormatting);

        // Now remove all runs in the sequence.
        foreach (Run run in runs)
            run.Remove();

        // Signal to the replace engine to do nothing because we have already done all what we wanted.
        return ReplaceAction.Skip;
    }

    private static Run SplitRun(Run run, int position)
    {
        Run afterRun = (Run)run.Clone(true);
        afterRun.Text = run.Text.Substring(position);
        run.Text = run.Text.Substring(0, position);
        run.ParentNode.InsertAfter(afterRun, run);
        return afterRun;
    }
}
