Parsing a String into Paragraphs Using a Regular Expression
This example demonstrates how to parse a CharSequence into an array of
paragraphs. A paragraph is a contiguous sequence of non-blank lines
separated by one or more blank lines. The lines in a paragraph can be
terminated with any of the legal line termination character sequences:
\r, \r\n, or \n.
CharSequence inputStr = "a\r\rb"; // Mac
inputStr = "a\r\n\r\nb"; // Windows
inputStr = "a\n\nb"; // Unix
String patternStr = "(?<=(\r\n|\r|\n))([ \\t]*$)+";
// Parse the input into paragraphs
String[] paras = Pattern.compile(patternStr, Pattern.MULTILINE).split(inputStr);
// Get paragraphs
for (int i=0; i<paras.length; i++) {
String paragraph = paras[i];
}
