Auto Refreshing ImportXML Google Sheets - google-apps-script

Question

I have a sheet that imports data from a site, there are about 10 imports all slightly different. I want a way that I could update that every five minutes or so. I know there are scrips to do it but when I tried to use one it would just put ?update at the end and mess up the entire import. I can show the script I am using. It is from 4 years ago and maybe it is outdated. Any help would be appreciated.
Also just having a script that changes the = to nothing then adds it back again or something would work I guess.
Here is the script I am using
function RefreshImports() {
var lock = LockService.getScriptLock();
if (!lock.tryLock(5000)) return; // Wait up to 5s for previous refresh to end.
var id = "Sheets ID";
var ss = SpreadsheetApp.openById(id);
var sheet = ss.getSheetByName("Sheet Name");
var dataRange = sheet.getDataRange();
var formulas = dataRange.getFormulas();
var content = "";
var now = new Date();
var time = now.getTime();
var re = /.*[^a-z0-9]import(?:xml|data|feed|html|range)\(.*/gi;
var re2 = /((\?|&)(update=[0-9]*))/gi;
var re3 = /(",)/gi;
for (var row=0; row<formulas.length; row++) {
for (var col=0; col<formulas[0].length; col++) {
content = formulas[row][col];
if (content != "") {
var match = content.search(re);
if (match !== -1 ) {
// import function is used in this cell
var updatedContent = content.toString().replace(re2,"$2update=" + time);
if (updatedContent == content) {
// No querystring exists yet in url
updatedContent = content.toString().replace(re3,"?update=" + time + "$1");
}
// Update url in formula with querystring param
sheet.getRange(row+1, col+1).setFormula(updatedContent);
}
}
}
}
// Done refresh; release the lock.
lock.releaseLock();
// Show last updated time on sheet somewhere
sheet.getRange(12,2).setValue("Rates were last updated at " + now.toLocaleTimeString())
}

Answer 1

You can write a script that retrieves the formula from the specified cell and sets it back to the same cell on a timer
For this you need:
Retrieve the formula with getFormula()
Set the formula back into the same cell with getFormula()
Bind an installable time-driven trigger to your function specifying the desired interval
Sample:
function setMeOnTrigger() {
var sheet = SpreadsheetApp.getActive().getActiveSheet();
var cell = sheet.getRange("C1");
cell.setFormula(cell.getFormula())
}
