在您的情况下，您需要实现IReplacingCallback接口来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;
}
///
/// 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;
}
}
