JQuery change the text to heading

JQuery change the text to heading

I have a named <form> (no id) with some text and input elements. I need to
change the format of the text to a heading style.
<form name="myform">
<br/>
Text Snippet #1<br/>
<input type="text"><br/>
<br>Text Snippet #2</br><br/>
<input type="text">`<br/>
</form>`<br/>
So in the example above, the Text Snippets #1 & 2 should be decorated with
<h1>Text Snippet #1</h1> and <br><h1>Text Snippet #2</h1></br>
respectively.
