Nokogiri tag position before/after content

I wanted to know if it's possible (and how of course) to get the position of a tag compare to the content of the parent tag. For example:

Case 1: <a>Hello<br/></a>

Case 2: <a><br/>Hello</a>

Here i want to know if br is place before or after "br" tag

EDIT: My real aim is actually to convert:

<a>Hello</a>
<a>World!<br/></a>
<a><br/>I</a>
<a>love</a>
<a>Rails.</a>

into 

Hello World!
I love Rails.

But my current code is convert it like that:

Hello World!
I
love Rails

Because i'm looking for each "a" tag and if br exist i create a new line.

Try to use children when get a. Something like this:

str = '<doc><a>Hello</a>
<a>World!<br/></a>
<a><br/>I</a>
<a>love</a>
<a>Rails.</a></doc>'

doc = Nokogiri::XML.parse(str)
out = ""
doc.css('doc a').each do |block|
  block.children.each do |node|
    if node.element?
      out += "<a></" + node.name + "></a>\n"
    else
      out += "<a>" + node.text + "</a>\n"
    end
  end
end
puts out

Output is:

<a>Hello</a>
<a>World!</a>
<a></br></a>
<a></br></a>
<a>I</a>
<a>love</a>
<a>Rails.</a>

You should cope with two br's in this case though...
