IE Does Not Ignore White Space in code

This:

<div id=”nav”>

<div
onmouseover=”this.style.backgroundImage=’url(images/nav_item_bg_hover.png)’;this.style.cursor = ‘pointer’;”
onmouseout=”this.style.backgroundImage=’url(images/nav_item_bg.png)’”
onclick=”window.open(‘index.html’)”>
|| Home</div>

<div
onmouseover=”this.style.backgroundImage=’url(images/nav_item_bg_hover.png)’;this.style.cursor = ‘pointer’;”
onmouseout=”this.style.backgroundImage=’url(images/nav_item_bg.png)’”
onclick=”window.open(‘bio.html’)”>
|| Bio</div></div>

Is NOT rendered the same in IE as this:

<div id=”nav”><div
onmouseover=”this.style.backgroundImage=’url(images/nav_item_bg_hover.png)’;this.style.cursor = ‘pointer’;”
onmouseout=”this.style.backgroundImage=’url(images/nav_item_bg.png)’”
onclick=”window.open(‘index.html’)”>
|| Home</div>

<div
onmouseover=”this.style.backgroundImage=’url(images/nav_item_bg_hover.png)’;this.style.cursor = ‘pointer’;”
onmouseout=”this.style.backgroundImage=’url(images/nav_item_bg.png)’”
onclick=”window.open(‘bio.html’)”>
|| Bio</div>
