Hello,
We have a file that contains token syntax, and during Word file generation, we insert the token name (e.g., <<LONGDATEM01>>) as per the predefined format. After this, we replace the token name with 25 blank spaces. In the next step, we replace these blank spaces back with the token name.
However, this process disrupts the token’s placement, causing misalignment of token images or incorrect positioning due to text shifting.
We need a way to ensure that when the token name is replaced with blank spaces and then restored, the formatting, spacing, and alignment remain intact, preserving the original text structure.
We are using below versions,
Aspose.Pdf - 17.3.0 and Aspose.Words - 24.1.0
When a token appears at the end of a line, it does not wrap to the next line as expected. Additional spaces are being added at the end of the line, pushing the text beyond the set margin.
Token Name -
Token Placement -
Please let me know if you need any further information.
@shivrajp MS Word documents are flow by their nature, so it is expected that when content is changed the remaining content is reflowed. Aspose.Words does not control this behavior.
Could you please attach your input and output documents and code that will allow us to reproduce the problem on our side? We will check the documents and provide you more information.
Below are the document for reference,
doc4.docx (11.6 KB)
doc1.docx (11.6 KB)
doc2.docx (11.5 KB)
doc1.docx (11.6 KB)
Code -
First we run below code where we replace the tokens with the empty string,
Dim PageSize As New [PaperSize]
Using inStream As New MemoryStream(fileData)
doc = New Aspose.Words.Document(inStream)
Dim builder As New DocumentBuilder(doc)
MultiDocxRef.PageCount = doc.PageCount
Dim PageHeight As Int64 = builder.PageSetup.PageHeight
Dim PageWidth As Int64 = builder.PageSetup.PageWidth
Dim DocumentHeight As Int64 = doc.PageCount * PageHeight
Dim DocumentWidth As Int64 = PageWidth
MultiDocxRef.PageHeight = PageHeight
MultiDocxRef.PageWidth = PageWidth
PageSize = builder.PageSetup.PaperSize
Dim options As New FindReplaceOptions()
options.ReplacingCallback = New ReplaceEvaluatorSignature()
Dim Regex As New Regex(TokenPattern, RegexOptions.None)
'Replace all tokens with blank string .
doc.Range.Replace(Regex, " ", New FindReplaceOptions)
'doc.Range.Replace(Regex, " ")
End Using
For Each section As Section In doc
section.PageSetup.PaperSize = PageSize
Next
doc.UpdatePageLayout()
Here we get the token name back where we has replaced it with the empty string,
Using inStream As New MemoryStream(fileData)
doc = New Aspose.Words.Document(inStream)
Dim builder As New DocumentBuilder(doc)
Dim PageHeight As Int64 = builder.PageSetup.PageHeight
Dim PageWidth As Int64 = builder.PageSetup.PageWidth
Dim DocumentHeight As Int64 = doc.PageCount * PageHeight
Dim DocumentWidth As Int64 = PageWidth
Dim options As New FindReplaceOptions()
options.ReplacingCallback = New FindAndInsertBookmark()
Dim Regex As New Regex(TokenPattern, RegexOptions.IgnoreCase)
doc.Range.Replace(Regex, "", options)
End Using
@shivrajp As it was mentioned, MS Word documents are flow by their nature, so it is expected that when content is changed the remaining content is reflowed.
If your goal is to visually hide the token keeping the original document layout, probably you can simply change the font color of the token to white:
Document doc = new Document(@"C:\Temp\in.docx");
FindReplaceOptions opt = new FindReplaceOptions();
opt.ApplyFont.Color = Color.White;
opt.UseSubstitutions = true;
doc.Range.Replace("<<LONGDATEM01>>", "$0", opt);
doc.Save(@"C:\Temp\out.docx");

This solution is working for me.
Thank you Alexey!

I need one more suggestion on below code,
If signedToken.TokenName.Contains("LONGDATE") Then
Dim months As String() = {"march", "april", "may", "june", "july", "august"}
If months.Any(Function(m) line.IndexOf(m, StringComparison.OrdinalIgnoreCase) >= 0) Then
textFragment.TextState.Font = FontRepository.FindFont("Times New Roman") ' ✅ Corrected font setting
textFragment.TextState.FontSize = 10
textFragment.TextState.HorizontalAlignment = HorizontalAlignment.Center
textFragment.HorizontalAlignment = HorizontalAlignment.Center
Else
textFragment.TextState.FontSize = 8.5
End If
End If
Here, line is ‘March 20, 2025’ or ‘August 20, 2025’ or ‘September 20, 2025’ then how I can change the font family of the same and please confirm text alignment center is also correct or not.
@shivrajp Could you please attach your input and expected output documents here for our reference? We will check the documents and provide you more information.
Please find attached document in which I have mentioned the details.
Date Token Center Align Text.docx (24.6 KB)
Thank you!
@shivrajp Thank you for additional information. You can use code like the following to achieve what you need:
[C#]
Document doc = new Document(@"C:\Temp\in.docx");
Regex dateRegex = new Regex("(January|February|March|April|May|June|July|August|September|October|November|December)\\s+\\d{1,2},\\s+\\d{4}");
FindReplaceOptions opt = new FindReplaceOptions();
// Set font name applied to matched text
opt.ApplyFont.Name = "Arial";
opt.ApplyFont.Color = Color.Red;
opt.ApplyFont.Bold = true;
// Use substitutions to replace the matched value with itself.
opt.UseSubstitutions = true;
doc.Range.Replace(dateRegex, "$0", opt);
// Post-process the document to apply paragraph alignment.
foreach (Run r in doc.GetChildNodes(NodeType.Run, true))
{
if (dateRegex.IsMatch(r.Text))
r.ParentParagraph.ParagraphFormat.Alignment = ParagraphAlignment.Center;
}
doc.Save(@"C:\Temp\out.docx");
[VB.NET]
Dim Doc As New Document("C:\Temp\in.docx")
Dim dateRegex As New Regex("(January|February|March|April|May|June|July|August|September|October|November|December)\s+\d{1,2},\s+\d{4}")
Dim opt As New FindReplaceOptions()
' Set font name applied to matched text
opt.ApplyFont.Name = "Arial"
opt.ApplyFont.Color = Color.Red
opt.ApplyFont.Bold = True
' Use substitutions to replace the matched value with itself.
opt.UseSubstitutions = True
Doc.Range.Replace(dateRegex, "$0", opt)
For Each r As Run In Doc.GetChildNodes(NodeType.Run, True)
If dateRegex.IsMatch(r.Text) Then
r.ParentParagraph.ParagraphFormat.Alignment = ParagraphAlignment.Center
End If
Next
Doc.Save("C:\Temp\out.docx")
out.docx (14.1 KB)
Just having a question about like when we have a token with text surrounded in multiple lines so at that time this solution will work?
Because the I think ParagraphFormat will update all the text of that paragraph.
@shivrajp You are free to change the code according to your needs. For example you can check whether the paragraph contains only the run with the matched text and change the paragraph alignment only in this case. The provided code simple demonstrates the technique.
