[logback-user] How to add less than (<) and greater than (>) in logback.xml

Crossposting from stackoverflow <https://stackoverflow.com/questions/48341348/how-to-add-less-than-and-greater-than-in-logback-xml> Can someone let me know how can I add less than (<) and greater than (>) sign in logback.xml? I want to have a encoder.pattern like below <encoder> <pattern>%p [%d{yyyy-MM-dd HH:mm:ss,SSS}] %c{3}:[%C{1}:%M:%L] - [%t] - %replace(%.-20480m){'[^A-Za-z0-9=<>:@\\-\\[\\]\n\\s!]','_'}%n </pattern><encoder> But this is failing because of the presence of <> ? Thanks, Debraj
