I need to replace a text using javascript and regex. Such that the words borex, edge and rss feeds get replaced with borex, edge and rss feeds.
The text appears like this. 

<body>
<img src="http://some.web.site/image.jpg" title="borex" />
These words are highlighted: borex, edge, rss feeds while these words are not: bewedge, borexlumina, rss feedssss
</body>

Get replaced with:

<body>
<img src="http://some.web.site/image.jpg" title="borex" />
These words are highlighted: <b>borex</b>, <b>edge</b>, <b>rss feeds</b> while these words are not: bewedge, borexlumina, rss feedssss
</body>

I tried:

var str = document.getElementByTagName("body")
 str.replace(/borex/g,'<b>borex</b>').replace(/edge/g,'<b>edge</b>').replace(/rss feeds/,'<b>rss feeds</b>')

This gets all of them. How do i get only the word that is not part of another word? Any other suggestions are welcome.. Need some help…

    Use \b to indicate a word boundry:

    str.replace(/\b(borex|edge|rss feeds)\b/g, '<b>$1</b>');
