在您的情況下，您需要實(shí)現(xiàn)IReplacingCallback接口來查找文本并將其替換為文檔(rtf) . 使用以下代碼示例來滿足您的要求 .

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類：

private class FindandInsertDocument : IReplacingCallback

{

private String path;

public FindandInsertDocument(String documentpath)

{

path = documentpath;

}

///

/// This method is called by the Aspose.Words find and replace engine for each match.

///

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;

}

}
