I played around on this a while back... I recall I used a Perl script to process the text to escape metacharacters. (I used the quotemeta builtin Perl function that escapes just about everything not alphanumeric with a backslash - even spaces!). I could not get it to work though - even with modifiers. I _suspect_ it could be a line terminator issue - I suspect Java does something strange with line terminations of text pasted into a textbox. Obviously, even if it works, a 4-step process involving external tools isn't practical for everyday use. Ideally, an 'Enhanced Response Assertion' element would allow me to simply paste in a full document, mark certain of text, and edit them as regular expressions (these would then display in a different font or color).
