Solution

  • While there are better means to make sure your email regex is valid (see @Tushar's comment), I'd like to explain what the problem is with your regex.

    The ^([\\p{L}+|\\p{N}*][@][\\p{L}+][.][\\p{L}+])$ contains incorrectly formed character classes [\\p{L}+|\\p{N}*] and [\\p{L}+]. They match a single character defined inside them - [\\p{L}+|\\p{N}*] matches either a p, {, L, etc. and [\\p{L}+] matches either a p, {, L, }, or +.

    If you plan to use your approach, you might want to fix the regex as

    XRegExp('^[\\p{L}\\p{N}]+@\\p{L}+[.]\\p{L}+$')
