Javascript: Encoding Values in XML Strings for AJAX / Web 2.0
I have written a very simple javascript function to do the job. The function takes a Javascript string (or any value, integer etc.) as input, converts it into a string and then replaces all occurrences of <, >, &, ", and ' with their html values. Please note that on the server side e.g. in PHP, ASP you have to decode the xml values to process them properly. I have also written the PHP function, which is described here.
function xml_encode(input) { if(input == undefined) { alert("error in xml_encode: input undefined"); return; } input = trim(input.toString()); var replace_with = '&'; // The 'g' in the first argument is used to tell the function 'replace' // that all occurences (g = global) // of the character in between slashes have to be replaced. input = input.replace(/&/g, replace_with); replace_with = '<'; input = input.replace(/</g, replace_with); replace_with = '>'; input = input.replace(/>/g, replace_with); replace_with = '''; input = input.replace(/'/g, replace_with); replace_with = '"'; input = input.replace(/"/g, replace_with); return input; }
Using xml_encode() - A simple example (JavaScript Code):
So, now let's say you want to create an XML string manually (in JavaScript) you'll use the function as follows:
var xml = "<?xml version='1.0' standalone='yes'?>"; name_variable = trim(document.getElementById('your_name').value); xml += "<name>"; xml += xml_encode(name_variable); xml += "</name>";
The trim function used in the example above is defined here.
