Regex to match not start of line

Question

I have the following XML tag

I want to replace the < in the text with <

Answer 1

@duncan's method works fine if you just want to replacing, but it doesn't match the <. and all the lookbehind wont work if you a using javascript. because javascript doesn't support lookbehind, unless you turn on the --harmony flag in nodejs or experimental javascript features in chrome. But lookahead will work here, which is: /(?!^) will match the < which is not at the begining of a line. and the replacing will be: ''.replace(/(?!^)
