@Rubal I do not see any content controls in your input document. I see text placeholders like {palceholder}. I suppose you are using Find/Replace functionality and IReplacingCallback to replace placeholders with real data. Please try using FindReplaceDirection.Backward instead of FindReplaceDirection.Forward in FindReplaceOptions.Direction and let us know if the problem still persist.
@Rubal If you need to replace text placeholders in your document with content control, you can use the following code:
Document doc = new Document(@"C:\Temp\in.docx");
FindReplaceOptions opt = new FindReplaceOptions(FindReplaceDirection.Backward, new ReplaceEvaluatorFindAndReplaceWithContentControl());
doc.Range.Replace(new Regex(@"\{[^\{\}]+\}"), "", opt);
doc.Save(@"C:\Temp\out.docx");
internal class ReplaceEvaluatorFindAndReplaceWithContentControl : 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;
// 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 SDT.
StructuredDocumentTag tag = new StructuredDocumentTag(doc, SdtType.RichText, MarkupLevel.Inline);
tag.Tag = e.Match.Value;
runs[0].ParentNode.InsertBefore(tag, runs[0]);
// 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;
}
