How to Repeat signature horizontally based on Characters

We have a word document with [Signature] Key as a paragraph, All we need to do is replace with signature with some Names, based on the names we need to repeat the [signature] key.


Ex: if names are containing 10 to 15 characters it should be repeat 2 times in a row like below

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX


if names are containing 5 charecters should be repeat 3 times

XXXXXXXXXXXXXX XXXXXXXXXXXXXX XXXXXXXXXXXXXXX
based on the name node will repeat…?

please help how to solve this task …

Hi Sudheer,

Thanks for your inquiry. You can achieve your requirement by implementing IReplacingCallback interface. Please use the same approach shared at following documentation link to find text and insert the signature. See the highlighted code snippet below.
http://www.aspose.com/docs/display/wordsnet/How+to+Find+and+Highlight+Text

Please read the following article about 'Find and Replace' and check the following code example for your kind reference.
http://www.aspose.com/docs/display/wordsnet/Find+and+Replace+Overview

Hope this helps you. Please let us know if you have any more queries.

If you still face problem, please share your input and expected output document here for our reference. We will investigate how you want your final Word output be generated like. We will then provide you more information on this along with code.


Document doc = new Document(MyDir + "in.docx");

doc.Range.Replace(new Regex(@"\[Signature\]", RegexOptions.IgnoreCase), new ReplaceEvaluatorSignature(), false);

doc.Save(MyDir + "Out.docx");

public class ReplaceEvaluatorSignature : IReplacingCallback

{

///

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

/// This method highlights the match string, even if it spans multiple runs.

///

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 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 Buidler

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

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

//Your code comes here

//write the keys according to your requirements

builder.Write("XXXXXXX");

// 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;

}

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;

}

}


Hi tahir.manzoor thanks for your replay.


in the following snippet how can we send multiple Keys.

//Your code comes here

//write the keys according to your requirements

builder.Write(“XXXXXXX”);

Hi Sudheer,

based on the name node will repeat...?


According to your requirements, you can write the contents with DocumentBuilder.Write method at the position of highlighted code.
