BibTeX entry

 @misc{ wiki:xxx,
   author = ""A B C"",
   title = "Regular Expressions --- "A B C"{,} ",
   year = "2014",
   url = "http://steipe.biochemistry.utoronto.ca/abc/index.php?title=Regular_Expressions&oldid=7037",
   note = "[Online; accessed 25-November-2025]"
 }

When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = ""A B C"",
   title = "Regular Expressions --- "A B C"{,} ",
   year = "2014",
   url = "\url{http://steipe.biochemistry.utoronto.ca/abc/index.php?title=Regular_Expressions&oldid=7037}",
   note = "[Online; accessed 25-November-2025]"
 }
