Catch string first with regex

Question

I need to do a regex for an application from which I need to remove a certain combination of characters from within a string. Explaining the problem better.

I have a string that returns from the database, something like this:

EVENTDATE:10/10/2015|*EDITAR_EVENTDATE:IwCalendar|EVENTTIME_INI:12:00|EVENTTIME_END:13:00|RANKINGHC:0|ALERGIAS:0|QUAIS_ALERGIAS:|INFECCAO:0|DATA_INFEC:|SITIO:0|QUADROCLINICO:|ASPECTO:0| ...

In this string I have values like this:

*EDITAR_EVENTDATE:IwCalendar|
*EDITAR_TQT_DTULTTROCA:IwCalendar|
*EDITAR_GTT_DTULTTROCA:IwCalendar|

It’s a pattern, I need to remove everything that starts with * and has the value IwCalendar and the pipe | at the end of the string, i.e., remove the sayings whose.

I need to do something generic because there are dozens of fields like this.

Already thank you for the strength!!! Good morning to all.

Ewerton,

You can do it like this.

var stringTeste = "EVENTDATE:10/10/2015|*EDITAR_EVENTDATE:IwCalendar|EVENTTIME_INI:12:00|EVENTTIME_END:13:00|RANKINGHC:0|ALERGIAS:0|QUAIS_ALERGIAS:|INFECCAO:0|DATA_INFEC:|SITIO:0|QUADROCLINICO:|ASPECTO:0|*EDITAR_EVENTDATEEND:IwCalendar|";


var expressaoRegular = /\*.*?IwCalendar\|/gm;
var resultado = stringTeste.match(expressaoRegular);
console.log(resultado);

var resultado2 = stringTeste.replace(expressaoRegular, " ");

console.log(resultado2);
