How to remove \r from paragraph

In my code I’m trying to remove a carriage return from the paragraph, see code below:

if (PreviousParagraph != null && PreviousParagraph.Range.Text == "<PAGEBREAK>\r")
{
    PreviousParagraph.Range.Replace(ControlChar.Cr, "");
}

However this doesn’t remove the carriage return. I also noticed that the paragraph only has one run with content <PAGEBREAK>, so I’m not sure where the carriage return is coming from.
Should it be possible to remove the carriage return this way or do I need to handle this differently?

To remove a carriage return from a paragraph in Aspose.Words, you can use the Replace method as you are currently doing. However, if the carriage return is not being removed, it may be due to the way the text is structured or how the control characters are represented in the document.

Here are a few suggestions to troubleshoot and resolve the issue:

  1. Check for Other Control Characters: Ensure that the carriage return is indeed the character you are trying to remove. Sometimes, text may contain other control characters like line feeds (ControlChar.Lf) or paragraph breaks (ControlChar.ParagraphBreak). You can try replacing these as well.

  2. Use a More Comprehensive Replace: Instead of just replacing ControlChar.Cr, you might want to replace all types of line breaks. Here’s an example of how you can do this:

    if (PreviousParagraph != null && PreviousParagraph.Range.Text == "<PAGEBREAK>\r")
{
    PreviousParagraph.Range.Replace(ControlChar.Cr, "");
    PreviousParagraph.Range.Replace(ControlChar.Lf, "");
    PreviousParagraph.Range.Replace(ControlChar.ParagraphBreak, "");
}

  3. Inspect the Text: You can print out the text of the paragraph to see exactly what characters are present. This can help you identify if there are unexpected characters that need to be handled.

  4. Use Regular Expressions: If the carriage return is part of a more complex string, consider using regular expressions to remove it. Here’s an example:

    using System.Text.RegularExpressions;

if (PreviousParagraph != null)
{
    string text = PreviousParagraph.Range.Text;
    text = Regex.Replace(text, @"\r", ""); // Remove carriage returns
    PreviousParagraph.Range.Text = text; // Update the paragraph text
}

By following these steps, you should be able to effectively remove the carriage return from your paragraph. If the issue persists, consider checking the document structure or any additional formatting that might be affecting the text.

@PStevelmans You cannot simply remove paragraph break in Aspose.Words DOM. If your goal is to remove paragraph break between two paragraph, you should move content from one paragraph to another and remove empty paragraph. For example see the following code:

Document doc = new Document(@"C:\Temp\in.docx");

Paragraph first = doc.FirstSection.Body.Paragraphs[0];
Paragraph second = doc.FirstSection.Body.Paragraphs[1];
// Move content from the second paragraph to the first one.
while(second.HasChildNodes)
    first.AppendChild(second.FirstChild);
// Remove empty second paragraph.
second.Remove();

doc.Save(@"C:\Temp\out.docx");
