I have a text placeholder in a word document. Example: . How do I insert a table at that location? I did not find a suitable findAndReplace solution for it.
Not sure about the static method splitAndrun. Can you please confirm?
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("placeholder", "", opts);
doc.Save("E:\\Temp\\20.6.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.
Thank you. I am using the Java library. Shouldn’t be a big deal to convert it to Java apis’
Please check the following Java code:
Document doc = new Document("E:\\Temp\\in.docx");
FindReplaceOptions opts = new FindReplaceOptions();
opts.setDirection(FindReplaceDirection.BACKWARD);
opts.setReplacingCallback(new ReplaceEvaluator());
doc.getRange().replace("placeholder", "", opts);
doc.save("E:\\Temp\\awjava-20.6.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.insertCell();

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;

Hello,
Thank you. I understand that with the ASPOSE Java library I cannot attach a PDF document to a word document.
Here is what I am trying to evaluate:
- I have a word document which has placeholders:
<<insertTable>> - with the above code insert a table.
<<pdfattachment>> - insert a PDF file
finally convert the entire word document to PDF. - This part is trivial
Is the only way to use ASPOSE PDF (java) in conjunction with words so I can insert a PDF either into a PDF or PDF into a word before conversion?
I am afraid, there is no way to insert a PDF file inside Word document by using Aspose.Words for Java API alone. But, you can insert Table and then save to PDF by using Aspose.Words for Java. After that you can load the second PDF in memory by using Aspose.PDF for Java API and merge it with Aspose.Words generated PDF. Please check the following article:
