Anyone know of a tool that will create an escaped string for use in AppleScript code?
What would be ideal is to use KM:
Select the string to be escaped
Run KM macro to create the escaped string and put on clipboard
For example, say I have a complex RegEx expression:
<\s*a\s+[^>]*href\s*=\s*[\"']?([^\"' >]+)[\"' >]
The tool would add the escape backslashes to output the string below that I need to use in AS code:
set strRegExPattern to "<\\s*a\\s+[^>]*href\\s*=\\s*[\\\"']?([^\\\"' >]+)[\\\"' >]"
Its really lucky you have Keyboard Maestro 7…

Except I don’t YET have Ver 7. I’ve got to upgrade two systems to Yosemite first. 
But thanks. Any Ver 6 solutions?
Well, the sequence of replaces for AppleScript is pretty straight forward:
\ ➤ \\
" ➤ \"
Then add a " at the start and the end.

Many thanks Peter. Works perfectly! 
Sorry I missed such an easy solution.
For some clouded reason I thought it was more complicated than that.
Thanks for taking the time to provide the actual code. 
For anyone interested, here's my slightly modified version of @peternlewis' macro:
