Extract the last word from a string, filter out any special characters, and store it in an array

Question

Extract the last word from a string, filter out any special characters, and store it in an array

Here is the content of the xmlhttp.responseText:

var Text = "FS2Crew A320 Checklist_1""FS2Crew Flight Crew A320 Main Ops Manual_1""FS2Crew Flight Crew A320 Main Ops Manual_10""FS2Crew Flight Crew A320 Main Ops Manual_11""FS2Crew Flight Crew A320 Main Ops Manual_12""FS2Crew Flight Crew A320 Main Ops Manual_13""FS2Crew Flight Crew A320 Main Ops Manual_14""FS2Crew Flight Crew A320 Main Ops Manual_2""FS2Crew Flight Crew A320 Main Ops Manual_3""FS2Crew Flight Crew A320 Main Ops Manual_4""FS2Crew Flight Crew A320 Main Ops Manual_5""FS2Crew Flight Crew A320 Main Ops Manual_6""FS2Crew Flight Crew A320 Main Ops Manual_7""FS2Crew Flight Crew A320 Main Ops Manual_8""FS2Crew Flight Crew A320 Main Ops Manual_9""FS2Crew Pushback Express Main Ops Manual_1""FS2Crew Pushback Express Main Ops Manual_2""FS2Crew Pushback Express Main Ops Manual_3""FS2Crew Pushback Express Main Ops Manual_4""FS2Crew Pushback Express Main Ops Manual_5""FS2Crew Pushback Express Main Ops Manual_6""FS2Crew Pushback Express Main Ops Manual_7""FS2Crew Pushback Express Main Ops Manual_8""VFR-Ffdfdfdlight-Planner-Dax_1""VFR-Ffdfdfdlight-Planner-Dax_2"

To achieve this, I want to extract specific strings from the content and form an array as follows:

result = [FS2Crew A320 Checklist~1, FS2Crew Flight Crew A320 Main Ops Manual~14, FS2Crew Flight Crew A320 Main Ops Manual~8, VFR-Ffdfdfdlight-Planner-Dax~2]

The desired format for these strings in the array is to remove the character (") and separate the file name from the occurrence count with (~).

Please overlook any errors in my English.

I successfully eliminated the characters and constructed an array.

Below is the function:

    function retrieveFiles(){
        var location = '/images';
        var xmlhttp = new XMLHttpRequest();
        src='files.php'
        xmlhttp.onreadystatechange = function() {

            if (xmlhttp.readyState == XMLHttpRequest.DONE) {   // XMLHttpRequest.DONE == 4
                if (xmlhttp.status == 200) {
            
                    var list = xmlhttp.responseText;
                    var arrStr = list.split(/[""][""]/);
                    var arrayLength = arrStr.length;
                    
                    arrStr.forEach(function (item) {
                        filename = item.replace('"', '')
                        console.log(filename);
                    });
                }
                else if (xmlhttp.status == 400) {
                    alert('Error 400 occurred');
                }
                else {
                    alert('A different status other than 200 was returned');
                }
            }
        };
        xmlhttp.open("GET", "filelist.txt", true);
        xmlhttp.send();
    }

Here is the outcome:

result: [FS2Crew A320 Checklist_1, FS2Crew Flight Crew A320 Main Ops Manual_1, FS2Crew Flight Crew A320 Main Ops Manual_10, FS2Crew Flight Crew A320 Main Ops Manual_11, FS2Crew Flight Crew A320 Main Ops Manual_12, FS2Crew Flight Crew A320 Main Ops Manual_13, FS2Crew Flight Crew A320 Main Ops Manual_14, FS2Crew Flight Crew A320 Main Ops Manual_2, FS2Crew Flight Crew A320 Main Ops Manual_3, FS2Crew Flight Crew A320 Main Ops Manual_4, FS2Crew Flight Crew A320 Main Ops Manual_5, FS2Crew Flight Crew A320 Main Ops Manual_6, FS2Crew Flight Crew A320 Main Ops Manual_7, FS2Crew Flight Crew A320 Main Ops Manual_8, FS2Crew Flight Crew A320 Main Ops Manual_9, FS2Crew Pushback Express Main Ops Manual_1, FS2Crew Pushback Express Main Ops Manual_2, FS2Crew Pushback Express Main Ops Manual_3, FS2Crew Pushback Express Main Ops Manual_4, FS2Crew Pushback Express Main Ops Manual_5, FS2Crew Pushback Express Main Ops Manual_6, FS2Crew Pushback Express Main Ops Manual_7, FS2Crew Pushback Express Main Ops Manual_8, VFR-Ffdfdfdlight-Planner-Dax_1, VFR-Ffdfdfdlight-Planner-Dax_2]
