The attached document is generated by Aspose by replacing all the place holders except one, that is in angular brackets…I want to change the color of the Angular brakets place holder if that is not found or replaced.
How to write the java code for that?
Hi Koteswara,
Thanks for your inquiry. You can achieve your requirement by implementing IReplacingCallback interface. Please use the same approach shared at following documentation link to achieve your requirements.
https://docs.aspose.com/words/java/find-and-replace/
Please
use the following code example to find the text and set its color. Hope this helps you. Please let us know if you have any more queries.
Document doc = new Document(MyDir + "Invoice+-+Title+V+Emissions+Fee.docx");
Pattern regex = Pattern.compile("", Pattern.CASE_INSENSITIVE);
doc.getRange().replace(regex, new ReplaceEvaluator(), false);
doc.save(MyDir + "Out.docx");
public 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());
// This array is used to store all nodes of the match for further highlighting.
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);
}
for (Run run : (Iterable) runs){
run.getFont().setColor(Color.BLUE);
}
// Signal to the replace engine to do nothing because we have already done all what we wanted.
return ReplaceAction.SKIP;
}
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;
}
}
