for-loop if statement not entering

The point is to filter through the nodes of an array and find the paragraph. The if statement is conditional tester is always false, hence never going in. But when I tested the node names using alerts, the 4th one is actually p.

//b is an array filled with 5 DOM Nodes one of which is a <p/>
for(var i=0;i<5;i++)
{   alert(b[i].nodeName);   //b[3].nodeName alerts p
    if(b[i].nodeName=="p")
    {
        //do something
        break;
    }
    else
    {
        continue;
    }
}

nodeName returns the tag name in uppercase (as does .tagName()); you're comparing it against lowercase.
