Hi support,
I’m trying to do following with Aspose Words library:
- Search for specific text (e.g, @@)
- Replace this text with an image.
- Save the document.
Can you please tell me if this is possible?

You can meet this requirement by using the following code:
public class Replacer : IReplacingCallback
{
public Replacer()
{
}
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;
}
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 highlighting.
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);
}
DocumentBuilder builder = new DocumentBuilder((Document)e.MatchNode.Document);
builder.MoveTo((Run)runs[runs.Count - 1]);
builder.InsertImage(@"D:\Temp\Aspose.Words.jpg");
//Now remove all runs in the sequence.
foreach (Run run in runs)
{
run.Remove();
}
return ReplaceAction.Skip;
}
}
