When we replace any thing in word, we see the new text as inserted and then the previous text as crossed.
If I want to reverse the order. is there a way/Functionality in aspose to do it.
I want the output similar to image “after.png”
see the attachment for better understanding.
@cacglo Currently, there is no built in way to achieve this. I have logged this issue as WORDSNET-23740. We will investigate the issue and let you know whether Aspose.Words can mimic MS Word behavior in this scenario.
As a temporary workaround you can use IReplacingCallback to achieve what you need. For example see the following code:
Document doc = new Document(@"C:\Temp\in.docx");
doc.StartTrackRevisions("aspose");
FindReplaceOptions options = new FindReplaceOptions();
options.Direction = FindReplaceDirection.Backward;
options.ReplacingCallback = new ReplaceEvaluatorFindAndReplace();
doc.Range.Replace("Aspose", "aSPOSE", options);
doc.StopTrackRevisions();
doc.Save(@"C:\Temp\out.docx");
private class ReplaceEvaluatorFindAndReplace : IReplacingCallback
{
/// <summary>
/// This method is called by the Aspose.Words find and replace engine for each match.
/// </summary>
ReplaceAction IReplacingCallback.Replacing(ReplacingArgs e)
{
Document doc = (Document)e.MatchNode.Document;
// Stop tracking here
doc.StopTrackRevisions();
// 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);
}
// Clone the run from the match and put the replacement text in it.
Run lastRun = runs[runs.Count - 1];
Run replacement = (Run)lastRun.Clone(true);
// Put the replacement run right after matched runs.
lastRun.ParentNode.InsertAfter(replacement, lastRun);
replacement.Text = "";
// Resume tracking
doc.StartTrackRevisions("test");
replacement.Text = e.Replacement;
// Delete matched runs
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);
run.ParentNode.InsertAfter(afterRun, run);
afterRun.Text = run.Text.Substring(position);
run.Text = run.Text.Substring((0), (0) + (position));
return afterRun;
}
