javascript - Replace a substring of a given length after a spefic piece of text

Question

I'm stuck :) Using javascript. I get an output from an instrument of which below is a partial outtake. I need to verify this data. On the line beginning 'MSH', after instrument field is a date and time
20210204220807+00:00
This repeats several time in the output and I want to strip it out of the string.

I will have the system date and time to the minute. For example 202102042208 . How can I use this to remove the whole text everywhere it appears? So replace 202102042208 + the next 8 characters.

No idea how I can do this? Any help is appreciated

MSH|^~&|New1|| Instrument 1||**20210204220807+00:00**||RSP^K11^RSP_K11|547CwlxiBkSMM9D2tSU+pw|P|2.5.1||||||UNICODE UTF-8|||LAB-27R^wegewg

Answer 1

you can use ^(MSH.*)202102042208.{8}

• ^(MSH.*), capture match string start from MSH to **, it will be used for replacement or $1
• .{8} match any characters with length of 8

var str = `MSH|^~&|New1|| Instrument 1||**20210204220807+00:00**||RSP^K11^RSP_K11|547CwlxiBkSMM9D2tSU+pw|P|2.5.1||||||UNICODE UTF-8|||LAB-27R^wegewg

str = str.replace(/^(MSH.*)202102042208.{8}/gm, '$1Date_Removed')
console.log(str)
