Hi guys,
My problem: How to replace a variable (ex. {{pricing.rent}}) by a simple table format with 2 columns and 2 rows.
With your examples, I easy to generate with format defined.
Is there any ideas?
Thanks,
Khoa
Please try using the following code:
Document doc = new Document("E:\\temp\\in.docx");
FindReplaceOptions opts = new FindReplaceOptions();
opts.Direction = FindReplaceDirection.Backward;
opts.ReplacingCallback = new ReplaceEvaluator();
doc.Range.Replace("{{pricing.rent}}", "", opts);
doc.Save("E:\\Temp\\19.5.docx");
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), (0) + (position));
run.ParentNode.InsertAfter(afterRun, run);
return afterRun;
}
private class ReplaceEvaluator : IReplacingCallback
{
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);
}
//// to insert Table
DocumentBuilder builder = new
DocumentBuilder((Document)e.MatchNode.Document);
builder.MoveTo((Run)runs[runs.Count - 1]);
Table table = builder.StartTable();
builder.InsertCell();
builder.Write("This is row 1 cell 1");
builder.InsertCell();
builder.Write("This is row 1 cell 2");
builder.EndRow();
builder.InsertCell();
builder.Writeln("This is row 2 cell 1");
builder.InsertCell();
builder.Writeln("This is row 2 cell 2");
builder.EndRow();
builder.EndTable();
foreach (Run run in runs)
run.Remove();
return ReplaceAction.Skip;
}
}
Hope, this helps.
Sorry, Awais! I’m working with Java language. Can you help me to change something?
My template includes 2 variables {{organization.name}} and {{pricing.rent}} in order position such as:
Organization name: {{organization.name}}
{{pricing.rent}}
Please try using the following Java code:
Document doc = new Document("E:\\Temp\\input.docx");
FindReplaceOptions opts = new FindReplaceOptions();
opts.setDirection(FindReplaceDirection.BACKWARD);
opts.setReplacingCallback(new ReplaceEvaluator());
doc.getRange().replace("{{pricing.rent}}", "", opts);
doc.save("E:\\Temp\\awjava-19.5.docx");
static class ReplaceEvaluator 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 insert Table
DocumentBuilder builder = new DocumentBuilder((Document)e.getMatchNode().getDocument());
builder.moveTo((Run)runs.get(runs.size() - 1));
Table table = builder.startTable();
builder.insertCell();
builder.write("This is row 1 cell 1");
builder.insertCell();
builder.write("This is row 1 cell 2");
builder.endRow();
builder.insertCell();
builder.write("This is row 2 cell 1");
builder.insertCell();
builder.write("This is row 2 cell 2");
builder.endRow();
builder.endTable();
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;
}
}
Hope, this helps.
Thank so much!
