lex - how to match escape characters for / and \

Question

i'm looking for a way to way to match / and \ for example: if i get the string "hello\sir/!" i'd like to get hello\sir/!

Answer 1

Maybe try using (.*\\.*\/.*):

.* Should match every single character or nothing
\\ Should match a backslash (Two of them since you need to escape)
\/ Should match a common slash (With a backslash since you need to escape)
(...) Should be the capture group

Watch out for multiline tags (Depending on the text you want to match with)...
