How to add Superscirpt / Subscript text with in the existing document on specific text using Aspose.words java.
Ex: I’m having text like Addition of X in the document, So i need to find the text of Addition of X in the document and on top of X, I need to add 2 as superscript.
@csaspose You can achieve this using IReplacingCallabck. I have adopted the text highlight example for you.
Here is the code example:
Document doc = new Document(@"C:\Temp\in.docx");
FindReplaceOptions opt = new FindReplaceOptions();
opt.ReplacingCallback = new InsertSuperscriptCallabck();
doc.Range.Replace("Addition of X", "2", opt);
doc.Save(@"C:\Temp\out.docx");
private class InsertSuperscriptCallabck : IReplacingCallback
{
public ReplaceAction 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.
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 a run with superscript text after the last Run in the match.
Run lastRun = runs[runs.Count - 1];
Run superscript = (Run)lastRun.Clone(true);
superscript.Font.Superscript = true;
superscript.Text = e.Replacement;
lastRun.ParentNode.InsertAfter(superscript, lastRun);
// Signal to the replace engine to do nothing because we have already done all what we wanted.
return ReplaceAction.Skip;
}
/// <summary>
/// Splits text of the specified run into two runs.
/// Inserts the new run just after the specified run.
/// </summary>
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;
}
}
Document doc = new Document("C:\\Temp\\in.docx");
FindReplaceOptions opt = new FindReplaceOptions();
opt.setReplacingCallback(new InsertSuperscriptCallabck());
doc.getRange().replace("Addition of X", "2", opt);
doc.save("C:\\Temp\\out.docx");

// 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.getMatchOffset() > 0)
currentNode = SplitRun((Run)currentNode, e.getMatchOffset());
// This array is used to store all nodes of the match.
java.util.ArrayList<Run> runs = new java.util.ArrayList<Run>();
// Find all runs that contain parts of the match string.
int remainingLength = e.getMatch().group().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.getNextSibling();
} while (currentNode != null && currentNode.getNodeType() != 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 a run with superscript text after the last Run in the match.
Run lastRun = runs.get(runs.size() - 1);
Run superscript = (Run)lastRun.deepClone(true);
superscript.getFont().setSuperscript(true);
superscript.setText(e.getReplacement());
lastRun.getParentNode().insertAfter(superscript, lastRun);
// Signal to the replace engine to do nothing because we have already done all what we wanted.
return ReplaceAction.SKIP;

/// <summary>

private static Run SplitRun(Run run, int position)
{
Run afterRun = (Run)run.deepClone(true);
afterRun.setText(run.getText().substring(position));
run.setText(run.getText().substring(0, position));
run.getParentNode().insertAfter(afterRun, run);
return afterRun;
