Posting copy-able code in a blog

I ran into a problem where I could not put code into blog entries. So, after much research, I found that:

1. Make sure the maximum number of characters without spaces is 80. Anything else will be wrapped and lost

2. To add code (Java / C++ / C# etc.) in your blob entry, "Edit Html", and enclose the code in:

<pre style="font-size: 90%;"><code>
      --- PASTE CODE HERE ----
</code></pre>

3. To Embed / insert xml code into html / blog entry, you must get rid of all of these characters from XML and replace then with their equivalent HTML friendly format: '<', '>', '&'. For a pretty display, I also converted all tabs to 4 spaces. Here is Java code that helped me do just that:

import java.io.FileReader;

public class ConvertToHtml {

    public static void main(String[] args) throws Exception {
        if (args.length != 1) {
            usage();
            return;
        }

        FileReader fr = new FileReader(args[0]);
        int c;
        while ((c = fr.read()) != -1) {
            if (c == '<') {
                System.out.print("<");
            }
            else if (c == '>') {
                System.out.print(">");
            }
            else if (c == '&') {
                System.out.print("&");
            }
            else if (c == '\t') {
                System.out.print("    "); // 4 spaces to a tab
            }
            else {
                System.out.print((char) c);
            }
        }
        fr.close();
    }

    private static void usage() {
        System.out.println("This util converts input to html safe code");
        System.out.println("Please pass one and only one argument: file that needs converting. Output will be sent to stdout");
    }

}

Hope this helps. Please do post a comment, if you use some other way to make blog entries code friendly.
