Javascript that only targets groups that have a specific callout

Thanks @Eugene Tyson your script works great.

I have added smoe fuctionality to either proces the current document or all open documents.

// Main function
function main() {
    var scope = userInput();
    var foundCALLOUT = false;

    // Loop through the selected scope
    if (scope instanceof Array) {
        for (var i = 0; i < scope.length; i++) {
            foundCALLOUT = processDocument(scope[i]) || foundCALLOUT;
        }
    } else {
        foundCALLOUT = processDocument(scope);
    }

    if (foundCALLOUT) {
        alert("CALLOUT product pricing updated.");
    } else {
        alert("No CALLOUT product groups found.");
    }
}

// Function to process a document
function processDocument(doc) {
    var foundCALLOUT = false;

    // Loop through all groups in the document
    for (var i = 0; i < doc.allPageItems.length; i++) {
        var group = doc.allPageItems[i];

        // Check if the item is a group
        if (group instanceof Group) {
            // Check if the group contains a text frame with the word "CALLOUT"
            if (groupContainsCallout(group)) {
                foundCALLOUT = true;
                // Perform GREP find and replace to remove pricing
                removePricing(group);
            }
        }
    }

    return foundCALLOUT;
}

// Function to check if a group contains a text frame with the word "CALLOUT"
function groupContainsCallout(group) {
    for (var j = 0; j < group.allPageItems.length; j++) {
        var item = group.allPageItems[j];

        // Check if the item is a text frame
        if (item instanceof TextFrame) {
            // Check if the text frame contains the word "CALLOUT"
            if (item.contents.indexOf("CALLOUT") !== -1) {
                return true;
            }
        }
    }
    return false;
}

// Function to remove pricing using GREP find and replace
function removePricing(group) {
    for (var j = 0; j < group.allPageItems.length; j++) {
        var item = group.allPageItems[j];

        // Check if the item is a text frame
        if (item instanceof TextFrame) {
            // Perform GREP find and replace to remove pricing
            var grepFind = "(was \\$\\d+(\\.\\d{2})? now \\$\\d+(\\.\\d{2})?)\\s";
            var grepReplace = "";
            app.findGrepPreferences.findWhat = grepFind;
            app.changeGrepPreferences.changeTo = grepReplace;

            item.changeGrep();

            // Clear GREP preferences
            app.findGrepPreferences = NothingEnum.nothing;
            app.changeGrepPreferences = NothingEnum.nothing;
        }
    }
}

// Function to get user input for the scope
function userInput() {
    var w = new Window('dialog', 'Select Scope', undefined, { closeButton: false });
    w.alignChildren = 'right';
    var p = w.add('panel {alignChildren: "left"}');
    p.add('radiobutton {text: "Active document"}');
    p.add('radiobutton {text: "All open documents"}');

    var b = w.add('group');
    b.add('button', undefined, 'Cancel');
    b.add('button', undefined, 'OK');

    // Set default selection
    p.children[0].value = true;

    if (w.show() == 1) {
        if (p.children[0].value) {
            w.close();
            return [app.activeDocument]; // Return an array with the active document
        } else {
            w.close();
            var allOpenDocs = [];
            for (var i = 0; i < app.documents.length; i++) {
                allOpenDocs.push(app.documents[i]);
            }
            return allOpenDocs; // Return all open documents
        }
    } else {
        w.close();
        exit(); // Close the script if Cancel is clicked
    }
}

// Run the main function
main();

@Manan Joshi Thanks for your input.
Is it possible to see a version of the script using your approach?

We will be processing  alot of documents at once sometimes so any speed efficiencies would be appreciated.
