Hi !!
I need to change all the line break to paragraph break. I will not save the changes. I need this changes for doing some other processing.
Is there any solution in Java?
Regards.
Thanks for your request. Please try using the following code:
// Open document
Document doc = new Document("C:\\Temp\\in.docx");
doc.getRange().replace(new asposewobfuscated.rn(ControlChar.LineBreak), new LineBreakReplacer(), false);
doc.save("C:\\Temp\\out.docx");
public static class LineBreakReplacer implements IReplacingCallback
{
public int replacing(ReplacingArgs e)
{
// Get MatchNode, this is Run node where matched word starts
// The word can consist of more than one run,
// in this case MatchNode will represent only part of the word
Run matchRun = (Run) e.getMatchNode();
// We will store all parts of the word in the list
ArrayList mainTextNodes = new ArrayList();
// Get match word
String word = e.getMatch().getValue();
// The run can contain whole match word or part of the word
// When run contains only part of the word IndexOf will return negative value
int index = matchRun.getText().lastIndexOf(word);
int wordLength = word.length();
while (index <0)
index = matchRun.getText().lastIndexOf(word.substring(0, wordLength--));
// Match Run can contain text before match word, so we should split the Run
if (index> 0)
{
// Clone match run to preserve formating
Run beforeRun = (Run) matchRun.deepClone(true);
// Split text betwee two runs
beforeRun.setText(matchRun.getText().substring(0, index));
matchRun.setText(matchRun.getText().substring(index));
matchRun.getParentNode().insertBefore(beforeRun, matchRun);
}
// If the word is spanned to several Run nodes, we should find all runs that represent whole word
int currentIdx = word.length();
while (currentIdx> 0)
{
if (matchRun.getText().length()> currentIdx)
{
break;
}
else
{
mainTextNodes.add(matchRun);
currentIdx = currentIdx - matchRun.getText().length();
// If there is no next nodes, we should stop while loop
Node currentNode = matchRun.getNextSibling();
if (currentNode == null)
{
break;
}
else
{
// The next node could be not Run node (BookmarkStart or BookmarkEnd for instance)
// in this case we should move to the next node
while (currentNode != null)
{
if (currentNode.getNodeType() == NodeType.RUN)
{
matchRun = (Run) currentNode;
break;
}
currentNode = currentNode.getNextSibling();
}
}
}
}
// Now we should split the latest run in the sequence that represents whole word,
// if there is text after match word
if (matchRun != null)
{
if (matchRun.getText().length() == currentIdx)
{
mainTextNodes.add(matchRun);
}
else
{
Run lastRun = (Run) matchRun.deepClone(true);
lastRun.setText(matchRun.getText().substring(0, currentIdx));
matchRun.setText(matchRun.getText().substring(currentIdx));
matchRun.getParentNode().insertBefore(lastRun, matchRun);
mainTextNodes.add(lastRun);
}
}
// Move DocumentBuilder cursor to the run with line break ans insert a paragraph break.
DocumentBuilder builder = new DocumentBuilder((Document) e.getMatchNode().getDocument());
builder.moveTo((Node) mainTextNodes.get(0));
builder.writeln();
// Remove run(s) with line break
for (int i = 0; i <mainTextNodes.size(); i++)
{
Run currentRun = (Run) mainTextNodes.get(i);
currentRun.remove();
}
return ReplaceAction.SKIP;
}
}
Best regards,
Do you have a c# / .net Example ?
Where does asposewobfuscated come from ?
Hi Boas,
Thanks for your request. I have converted the above Java code to C#:
// Open document
Document doc = new Document("C:\Temp\in.docx");
doc.Range.Replace(new Regex(ControlChar.LineBreak), new LineBreakReplacer(), false);
doc.Save("C:\Temp\out.docx");
public class LineBreakReplacer : IReplacingCallback
{
ReplaceAction IReplacingCallback.Replacing(ReplacingArgs e)
{
// MatchNode, this is Run node where matched word starts
// The word can consist of more than one run,
// in this case MatchNode will represent only part of the word
Run matchRun = (Run)e.MatchNode;
// We will store all parts of the word in the list
ArrayList mainTextNodes = new ArrayList();
// Get match word
String word = e.Match.Value;
// The run can contain whole match word or part of the word
// When run contains only part of the word IndexOf will return negative value
int index = matchRun.Text.LastIndexOf(word);
int wordLength = word.Length;
while (index < 0)
index = matchRun.Text.LastIndexOf(word.Substring(0, wordLengthû));
// Match Run can contain text before match word, so we should split the Run
if (index > 0)
{
// Clone match run to preserve formating
Run beforeRun = (Run)matchRun.Clone(true);
// Split text betwee two runs
beforeRun.Text = (matchRun.Text.Substring(0, index));
matchRun.Text = matchRun.Text.Substring(index);
matchRun.ParentNode.InsertBefore(beforeRun, matchRun);
}
// If the word is spanned to several Run nodes, we should find all runs that represent whole word
int currentIdx = word.Length;
while (currentIdx > 0)
{
if (matchRun.Text.Length > currentIdx)
{
break;
}
else
{
mainTextNodes.Add(matchRun);
currentIdx = currentIdx - matchRun.Text.Length;
// If there is no next nodes, we should stop while loop
Node currentNode = matchRun.NextSibling;
if (currentNode == null)
{
break;
}
else
{
// The next node could be not Run node (BookmarkStart or BookmarkEnd for instance)
// in this case we should move to the next node
while (currentNode != null)
{
if (currentNode.NodeType == NodeType.Run)
{
matchRun = (Run)currentNode;
break;
}
currentNode = currentNode.NextSibling;
}
}
}
}
// Now we should split the latest run in the sequence that represents whole word,
// if there is text after match word
if (matchRun != null)
{
if (matchRun.Text.Length == currentIdx)
{
mainTextNodes.Add(matchRun);
}
else
{
Run lastRun = (Run)matchRun.Clone(true);
lastRun.Text = matchRun.Text.Substring(0, currentIdx);
matchRun.Text = matchRun.Text.Substring(currentIdx);
matchRun.ParentNode.InsertBefore(lastRun, matchRun);
mainTextNodes.Add(lastRun);
}
}
// MoveDocumentBuilder cursor to the run with line break ans insert a paragraph break.
DocumentBuilder builder = new DocumentBuilder((Document)e.MatchNode.Document);
builder.MoveTo((Node)mainTextNodes[0]);
builder.Writeln();
// Remove run(s) with line break
for (int i = 0; i < mainTextNodes.Count; i++)
{
RuncurrentRun = (Run)mainTextNodes[i];
currentRun.Remove();
}
return ReplaceAction.Skip;
}
}
I hope, this will help.
Best Regards,
