:What you could use instead is <code>var patt3 = new RegExp("\\*{"+(RegExp.$1.length+1)+"}");</code> which, for example, will give you the regex <code>/\*{3}/</code> when the <code>RegExp.$1</code> match is "**" - <u>'''[[User:Evad37|Evad]]''37'''''</u> <span style="font-size:95%;">[[[d:w:User talk:Evad37|talk]]]</span> 04:59, 7 May 2017 (UTCt)

To actually get valid regex, the match would have to be escaped (
