I want to create the similar xml structure. Means find “Schedule 1” and add fldchar Start, Seperator and End. How can I acheive this in Aspose

Yes correct. I added the IReplacingCallback function only, but not able to add fldChar Start, Seperator and End. How can I acheive this?
@coderthiyagarajan1980 You could use the following code to insert fldChar Start, Seperator and fldChar End:
Document doc = new Document("test.docx");
FindReplaceOptions options = new FindReplaceOptions(new ReplaceCallback());
doc.Range.Replace("Schedule 1", "", options);
class ReplaceCallback : IReplacingCallback
{
public ReplaceAction Replacing(ReplacingArgs e)
{
Document doc = (Document)e.MatchNode.Document;
// 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 deleting.
List<Run> runs = new List<Run>();
// 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((Run)currentNode);
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((Run)currentNode);
}
// Insert field after text
DocumentBuilder builder = new DocumentBuilder(doc);
builder.MoveTo(runs[runs.Count - 1]);
builder.InsertField("REF _Ref100000001 \\h", "Schedule 1");
// Remove text
runs.ForEach(r => r.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);
run.ParentNode.InsertAfter(afterRun, run);
afterRun.Text = run.Text.Substring(position);
run.Text = run.Text.Substring((0), (0) + (position));
return afterRun;
}
}
No, my requirement is to retain the text “Schedule 1” and then create cross refererence link. But the above code replaces the “Schedule 1.”
@coderthiyagarajan1980 The text “Schedule 1” is preserved inside the field. The output is like you described in the first post (see Replace.png (16.6 KB)). If you want to get different result please attach the desired output.
