How to NSLog with \n\r\t - iphone

Question

In my application I am reading an HTML page to a string. HTML Page contains many tags, new lines & many other characters.
<style type="text/css">
h3{
font-weight:bold;
line-height:18px;
font-family:Arial;
font-size:12px;
text-align:justify;
color:black;
background-color:transparent;
width:280px;
margin:0;
}
body{
font-weight:normal;
line-height:18px;
font-family:Arial;
font-size:12px;
text-align:justify;
color:black;
background-color:transparent;
width:280px;
}
</style>
I want to replace this string like following.
When we NSLog above HTML page, it will print as above looks. But What I want to NSLog is as follows
\t\t<style type="text/css">\n\t\t\th3{\n
font-weight:bold;
line-height:18px;
font-family:Arial;
font-size:12px;
text-align:justify;
color:black;
background-color:transparent;
width:280px;
margin:0;
}
body{
font-weight:normal;
line-height:18px;
font-family:Arial;
font-size:12px;
text-align:justify;
color:black;
background-color:transparent;
width:280px;
}
</style>
I mean including backslash characters. Is it possible? The reason behind this - I want to replace above style dynamically - but for replacing above I must have source to replace - How to get source including \n&\r characters ?

Look at the NSString reference. You'll need something like:
string = [oldString stringByReplacingOccurrencesofString: #"\n" withString: #"\\n"];
// repeat for \t and \r
