I am looking for my `input` element using Nokogiri's `xpath` method. 
It's returning an object of class `Nokogiri::XML::NodeSet`:

```
[#<Nokogiri::XML::Element:0x3fcc0e07de14 name="input" attributes=[#<Nokogiri::XML::Attr:0x3fcc0e07dba8 name="type" value="text">, #<Nokogiri::XML::Attr:0x3fcc0e07db94 name="name" value="creditInstallmentAmount">, #<Nokogiri::XML::Attr:0x3fcc0e07db44 name="style" value="width:240px">, #<Nokogiri::XML::Attr:0x3fcc0e07dae0 name="value" value="94.8">, #<Nokogiri::XML::Attr:0x3fcc0e07da18 name="readonly" value="true">]>

```

Is there a faster and cleaner way to get the value of `input` than casting this using `to_s`:

```
"<input type=\"text\" name=\"creditInstallmentAmount\" style=\"width:240px\" value=\"94.8\" readonly>"

```

and match with regular expressions?
