Question

I am very new to parsing XML data with javascript, so please excuse me if my question is a bit simple.

I am parsing data from an XMl file with javascript using a standard xmlHTTPRequest. The format of the URL that I am pulling the XML data from is something like: “http://example.com/abcyymmdd-data.xml”. The (yymmdd) portion of the url represents the date and the files are updated daily. I would like to insert a javascript code in the url in place of yymmdd so that a new XML file is parsed each day. How might I achieve this?

Thanks,
Carlos

Answer 1

You can retrieve the current date in yymmdd format like:

var d = new Date();
var date_string = 
    d.getFullYear().toString().substring(2) +
    (d.getMonth () < 9 ? "0" : "") + (d.getMonth() + 1) +
    (d.getDate() < 10 ? "0" : "") + d.getDate();
