How can I perform case-insensitive pattern search and case-preserving replacement?

Question

Here is the scenario.

String strText = \"ABC abc Abc aBC abC aBc ABc AbC\";
// Adding a HTML content to this
String searchText = \"abc\";
String strFormatted = s

You can use a backreference. Something like:

String strFormatted = strText.replaceAll(
    "(?i)(" + searchText + ")", 
    "$1");
