Returned output

['<input type="text" name="hostname">', '<input type="text" name="username" placeholder="root">', '<input type="number" name="tes" placeholder="4">']
None
['<input type="text" name="hostname">', '<input type="checkbox" name="rrrr">', '<input type="text" name="rrrrrr" placeholder="test">']
None

With some quick formatting it can produce the following output

 <form>
	<p>None</p>
	<input type="text" name="hostname">
	<input type="text" name="username" placeholder="root">
	<input type="number" name="tes" placeholder="4">
</form>

<form>
	<p>None</p>
	<input type="text" name="hostname">
	<input type="checkbox" name="rrrr">
	<input type="text" name="rrrrrr" placeholder="test">
</form>
