I'm writing a simple chrome extension. I need to create the ability to add sites URLs to a list, or read from the list.

I use the list to open the sites in the new tabs.

I'm looking for a way to have a data file I can write to, and read from. I was thinking on XML. I read there is a problem changing the content of files with Javascript.

Is XML the right choice for this kinda thing?

I should add that there is no web server, and the app will run locally, so maybe the problem websites are having are not same as this.

Before I wrote this question, I tried one thing, and started to feel insecure because it didn't work.

• I made a XML file called Site.xml:

<?xml version="1.0" encoding="utf-8" ?>

    <Sites>
  <site>
    <url>
      http://www.sulamacademy.com/AddMsgForum.asp?FType=273171&SBLang=0&WSUAccess=0&LocSBID=20375
    </url>
  </site>

  <site>
    <url>
      http://www.wow.co.il
    </url>
  </site>

  <site>
    <url>
      http://www.Google.co.il
    </url>
  </site>

• I made this script to read the data from him, and put in on the html file.

 function LoadXML() {
            var ajaxObj = new XMLHttpRequest();
            ajaxObj.open('GET', 'Sites.xml', false);
            ajaxObj.send();

        var myXML = ajaxObj.responseXML;
        document.write('<table border="2">');
        var prs = myXML.getElementsByTagName("site");
        for (i = 0; i < prs.length; i++) {
            document.write("<tr><td>");
            document.write(prs[i].getElementsByName("url")[0].childNode[0].nodeValue);
            document.write("</td></tr>");
        }
        document.write("</table");
    }
