Printing Tag Information Using Document.write

I have a script that parses an html page for its tags. Now I just want to print it to the screen but so far no matter what I try apache parses the output and uses the tags.

I want to be able to use document.write or some function to output a string that contains tags like <p>whatever</P> exactly like that, as it appears here so it shows up in the page just like that.

for (i=0; i < s.length; i++) {
c = s.charAt(i);
if (c == "<") {
j = s.indexOf(">", i+1);
if (j != -1) {
document.write("tag= " + s.substring(i,j+1));
i = j;
}
}
}
}
