Issue with \n

Hello,


I’m having an issue with Aspose. I have this string: “Prueba con salto de\nlinea” in a DataSet. When doing mailMerge.AddRegionData I get a square-like thing instead of a new line. See attachment for more details

Can anyone help me?

Thanks in advance

Hi

<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Thanks for your inquiry. I cannot reproduce the problem on my side. I use the latest version of Aspose.Words (7.0.0) for testing. You can download it from here:

http://www.aspose.com/community/files/51/.net-components/aspose.words-for-.net/category1188.aspx

Best regards.

Seems that the bug is with Advanced Mail Merge and not with Aspose, sorry for the trouble :slight_smile:

I have a similar issue with “\n”.
In my case I need to replace a text with a “new line” character. So I use this method:
this.Document.Range.Replace("[br]", “\n”, true, true);

The problem is that I get a square item instead the new line. Is there any way to do that?

Thanks in advance!!

Hi

Thanks for your inquiry. Please try using line break instead of paragraph break. Please see the following code:

Document doc = new Document(@"Test001\in.doc");

doc.Range.Replace("[br]", "\v", false, false);

doc.Save(@"Test001\out.doc");

Hope this helps.

Best regards,

Thanks for the quick answer!

It works like a charm for me.

Hello,

I thought I solved the problem with the \v replacement but I have received a few complains about it…

The problem is that if the paragraph is justified, it isn’t the same the line break and the paragraph break (see the lower image).



Is there any way to replace a text with a paragraph break?

Thanks in advance.

Hi<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Thanks for your inquiry. Yes, of course, you can achieve this, but in this case the solution will be a little bit heavier. You should use ReplaceEvaluator to insert paragraph break, but first you need to split the matched Run. Please try using the code below:

Document doc = new Document(@"Test001\in.doc");

doc.Range.Replace(new Regex(Regex.Escape("[br]")), new ReplaceEvaluator(ReplaceEvaluatorInsertParagraphBreak), false);

doc.Save(@"Test001\out.doc");

================================================================

///

/// This method is called by the Aspose.Words find and replace engine for each match.

/// This method inserts paragraph break at the location of the matched string.

///

private static ReplaceAction ReplaceEvaluatorInsertParagraphBreak(object sender, ReplaceEvaluatorArgs 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 removing.

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);

}

// Create Document Builder and insert paragraph break.

DocumentBuilder builder = new DocumentBuilder(e.MatchNode.Document as Document);

builder.MoveTo((Run)runs[runs.Count - 1]);

builder.Writeln();

// Now remove all runs in the sequence.

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;

}

///

/// Splits text of the specified run into two runs.

/// Inserts the new run just after the specified run.

///

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;

}

Hope this helps.

Hi,

I’ve tried your code and it seems to work great. It is heavier and a bit more complicated but it solves the problem.

Thanks again.
