Hi,
How can I replace some String to Field in a word?
Thanks.

For example, you can replace plain text in Word document with real merge fields by using following code of Aspose.Words for .NET.
Document doc = new Document("E:\\temp\\in.docx");
FindReplaceOptions opts = new FindReplaceOptions();
opts.ReplacingCallback = new ReplaceWithMergefield();
opts.Direction = FindReplaceDirection.Backward;
doc.Range.Replace(new Regex(@"\{(.*?)\}"), "", opts);
doc.Save("E:\\temp\\19.10.docx");
private class ReplaceWithMergefield : IReplacingCallback
{
public ReplaceAction 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);
}
DocumentBuilder builder = new DocumentBuilder((Document)e.MatchNode.Document);
builder.MoveTo((Run)runs[runs.Count - 1]);
builder.InsertField("MERGEFIELD \"" + e.Match.Groups[1].Value.Trim() + "\"", null);
//Now remove all runs in the sequence.
foreach (Run run in runs)
run.Remove();
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;
}
}
Hope, this helps in achieving what you are looking for.
sorry, I forgot to mention it, I use java ,do you have any java code?
Thanks a lot

You can build logic on the following Aspose.Words for Java code to get the desired output:
Document doc = new Document("E:\\temp\\in.docx");
Pattern pattern = Pattern.compile("\\{(.*?)\\}");
FindReplaceOptions opts = new FindReplaceOptions();
opts.setDirection(FindReplaceDirection.BACKWARD);
opts.setReplacingCallback(new ReplaceWithMergefield());
doc.getRange().replace(pattern, "", opts);
doc.save("E:\\Temp\\awjava-19.10.docx");
static class ReplaceWithMergefield implements IReplacingCallback {
public int replacing(ReplacingArgs e) throws Exception {
// This is a Run node that contains either the beginning or the complete match.
Node currentNode = e.getMatchNode();
// 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.getMatchOffset() > 0)
currentNode = splitRun((Run) currentNode, e.getMatchOffset());
ArrayList runs = new ArrayList();
// Find all runs that contain parts of the match string.
int remainingLength = e.getMatch().group().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.getNextSibling();
} while ((currentNode != null) && (currentNode.getNodeType() != 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);
}
// to do
DocumentBuilder builder = new DocumentBuilder((Document)e.getMatchNode().getDocument());
builder.moveTo((Run)runs.get(runs.size()-1));
builder.insertField("MERGEFIELD \""+e.getMatch().group(1) + "\"", null);
System.out.println("MERGEFIELD \""+e.getMatch().group(1) + "\"");
for (Run run : (Iterable<Run>) 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 Run splitRun(Run run, int position) throws Exception {
Run afterRun = (Run) run.deepClone(true);
afterRun.setText(run.getText().substring(position));
run.setText(run.getText().substring((0), (0) + (position)));
run.getParentNode().insertAfter(afterRun, run);
return afterRun;
}
}
ok, thanks a lot.
