javascript - how to get the value of all p and h tags in a html page excluding all other tags

I am trying to load a HTML page into my app. I want to show only the content of the HTML page. please help me with a javascript function where I can loop through all the p tags and get the content of the <p> tags to display in a TextView as string.

<html><body>" +
        "<h1>First</h1><p>text text text</p>" +
        "<h1>Second</h1>more text" +
         <p>text text text</p>
           <p>text text text</p>
          <p>text text text</p>
        "</body></html>

If you do not want to use jQuery just do:

var paragraphs = document.getElementsByTagName("p");
for(var i = 0; i < paragraphs.length; i++)
{
    alert(paragraphs[i].innerHTML);
}
