Retreving Parent Values for a given Attribute value

[pathisunil]

Dear All
I have an xmldocument which is as formed below. It is a bit of loopy in

nature. can anyone kindly let me know how can i write a xslt which
would take a parameter which is an attribute value and would like to
have details out of the xml file.
I will the paste the xmldocument for your reference.The values required

as output are based on reverse pattern.The functionality requires this
pattern.The values required are as follows:
Required Output:Which happen to be as given below
cars/make = "alfa romeo"
cars/make/shortmodels/shortmod*el = "147"
cars/make/shortmodels/shortmod*el/longmodels/longmodel = "Distinctiv e"

cars/make/shortmodels/shortmod*el/longmodels/longmodel/deriva*tives/derviate[@vehicle_id='14 *825420040501']

= "1.6 T.Spark Distinctive hatchback"
The above values which are in quotes must be returned after using an
xslt by giving the following attribute @vehicle_id='14 825420040501
This particular xml file contains only 1 make, but in the original file

this make would be repeated in nature.
Example of the XML File.
