using sed replace command with HTML brackets

I want to replace the angle brackets in this text.

Code:

<body> 

<p>

Here is some normal text

</p>

<span class="bigText">Monster Text!</span> 

<p>

Next to the big text 

</p>

so i figures i would use the sed replace commands however it does not replae the while tag - I get <lt; - it is skipping the ampersand and retaining the angle bracket - not replacing it.

Code:

more more_body | sed -e 's/</&lt;/g'





<lt;body> 



<lt;p>

Here is some normal text

<lt;/p>



<lt;span class="bigText">Monster Text!<lt;/span> 



<lt;p>

Next to the big text 

<lt;/p>

This is what I want it to look like :

Code:

&lt;body> 



&lt;p>

Here is some normal text

&lt;/p>



&lt;span class="bigText">Monster Text!&lt;/span> 



&lt;p>

Next to the big text 

&lt;/p>

I want the less than angle brackets replaces with the the html entity - <

& has special meaning in sed, you have to escape it

Code:

sed 's/</\</g' file...

man sed

Code:

...

s/regexp/replacement/

              Attempt  to match regexp against the pattern space.  If success-

              ful,  replace  that  portion  matched  with  replacement.    The

              replacement may contain the special character & to refer to that

              portion of the pattern space  which  matched,  and  the  special

              escapes  \1  through  \9  to refer to the corresponding matching

              sub-expressions in the regexp.
