Multilne search and replace

Hello,

the ActiproSoftware.Text.Searching namespace provides interesting low level search and replace operations but I would like to know if it could handle "as is" multiline search ans replace operations, say, if I provide search and replace strings with LF inside ?

For instance, I could have

using a;
using b;
using c;

with any line break characters to replace with

using x;
using y;

  in a single operation. Is it possible, or must I implement the parsing of the multiline string myself to break it in several single lines search and replace operations ?

Thank you.
