Hi there,

All you hopefully need to to is add an escaped backslash:

var matchString = new RegExp("[a-zA-Z0-9&-/\\]");

Hope it helps ;)

\section       Text string to be matched

\\section       Escaped backslash for re.compile

"\\\\section"       Escaped backslashes for a string literal

The regular expression \\ matches a single backslash. In JavaScript, this becomes re = /\\/ or re = new RegExp("\\\\").
Did that help?  Where you able to create the backslash.
