Hi,
We are using 30 days trial licence of Aspose java.
I have used find & highlight functionality .It works fine for one sentence.
Pattern regex = Pattern.compile(“the precise answer of the question articulated in natural”, Pattern.CASE_INSENSITIVE);
Now I have 2 sentences which I want to highlight.
Can I highlight 2 sentences at one go?
Pattern regex = Pattern.compile(“the precise answer of the question articulated in natural|We have limited this work to Hindi and Marathi language.”, Pattern.CASE_INSENSITIVE);
