"jsnapy --diff" is character based and not node/word based

whatever if the format is text or xml
test_bgp_neighbor:

• command: show bgp neighbor
  format: text
  test_rpc_version:
• rpc: get-software-information
  format: xml

so jsnapy uses several colors for

<output-octets>72198</output-octets>
<output-octets>72283</output-octets>  

and even 4 colors (white yellow red green) for:

<peer-state>Established</peer-state>
<peer-state>Active</peer-state>

these nodes are diff. it would be better to color the whole nodes with one single color (yellow).
Could we improve this? or control the number of colours?
