too long

I have data from SQL database that contains xml text which are being echoed with php script

For example this:
No:1|TestName:MachineAlfonso|TestParameter:< asdf/>|TestConnection:1234;

This data is later being parsed to Unity for later uses.
however when i try to print it in unity, It somehow converting the < to &lt ; and the > to &gt ;

The full output become
No:1|TestName:MachineAlfonso|TestParameter:&lt ; asdf/&gt ;|TestConnection:1234;

Is there any function to print the output to become a human readable sign not as html code? because those two signs( < and >) are just some than many other html simple that i want to convert.

this is the C# script i use to print the echoed data

   public IEnumerator RefreshData()
   {
        //load the data
        //dataLoader is the link of the echoed php data
        WWW InventoryDatabase = new WWW(dataLoaderURL);

        //wait until its done dowloading
        yield return InventoryDatabase;

        string abc = InventoryDatabase.text;
        Debug.Log("text is: " + abc);
   }

Try PHP's htmlentities() function. It's designed specifically for this purpose:

In the end, in order not to waste time, I just use replace like @derHugo has suggested.
Hopefully there are better and cleaner ways to do it. But hey, its a start. ^_^

Here is the code snippets if someone has similar problem:

     public IEnumerator RefreshData()
       {
            //load the data
            //dataLoader is the link of the echoed php data
            WWW InventoryDatabase = new WWW(dataLoaderURL);

            //wait until its done dowloading
            yield return InventoryDatabase;

             string temp = InventoryDatabase.text;
                    temp = temp.Replace("&lt;", "asdf");
                    temp = temp.Replace("&gt;", "<");
                    temp = temp.Replace("&amp;", "&");
                    temp = temp.Replace("&quot;", "\"");

            //this "Inventory" contains all the data from the echoed file
            string Inventory =  temp;

            string abc = InventoryDatabase.text;
            Debug.Log("text is: " + Inventory);
       }
