indexing a file

hello guys,

I have a file like this:

input.dat

Code:
Push-to-talk 
No
Coonection
IP support 
Support for IP telephony 
Yes 
Built-in SIP stack 
Yes 
Support via software 
Yes 
Microsoft
Support for Microsoft Exchange 
Yes 
UMA 
No 
Internet
Internet connection
WAP 
Yes 
Weight 
129 g 
GUI type
Display 
Colour 
Number of colours 
262144 
Display technology 
LCD
Display Resolution
Screen resolution  
320x480 pixels  
Screen size  
3.2 inches  
Touchscreen  
Yes  
Simultaneous touch points  
3+ Multi-touch  
Type of technology  
Capacitive

and the feature list is:

featureList.dat

Code:
Speaker
Support for IP telephony 
Support for Microsoft Exchange 
UMA 
WAP 
Weight 
Bluetooth
Dimension
Display technology 
Screen resolution  
Screen size  
Touchscreen  
Type of technology

and the desired output is:

output.dat:


Code:
null
Yes
Yes
No
Yes
129 g
null
null
LCD 
320x480 pixels
3.2 inches
Yes
Capacitive
null

I want to see what are the values of the features in the input file (features have their values in the line below them)

if the feature does not exist then the value would be "null"

there are some features in the input that are not in the featureList.dat, so just the desired features are the subject for the extraction.

I came up to this code by the help of Ahamed, but I have problem with it Smilie

Code:
awk '{gsub(/[ ]*$/,"")}NR==FNR{x=$0;getline;getline;a[x]=$0;next}{print a[$0]?a[$0]:"null"}'  file1 file2

Locale::Codes::LangExt(3)				User Contributed Perl Documentation				 Locale::Codes::LangExt(3)

NAME
Locale::Codes::LangExt - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangExt; $lext = code2langext('acm'); # $lext gets 'Mesopotamian Arabic' $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm' @codes = all_langext_codes(); @names = all_langext_names(); DESCRIPTION
The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in the IANA language registry. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language registry codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language extensions. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langext('acm','alpha'); $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic. This is the default code set. ROUTINES
code2langext ( CODE [,CODESET] ) langext2code ( NAME [,CODESET] ) langext_code2code ( CODE ,CODESET ,CODESET2 ) all_langext_codes ( [CODESET] ) all_langext_names ( [CODESET] ) Locale::Codes::LangExt::rename_langext ( CODE ,NEW_NAME [,CODESET] ) Locale::Codes::LangExt::add_langext ( CODE ,NAME [,CODESET] ) Locale::Codes::LangExt::delete_langext ( CODE [,CODESET] ) Locale::Codes::LangExt::add_langext_alias ( NAME ,NEW_NAME ) Locale::Codes::LangExt::delete_langext_alias ( NAME ) Locale::Codes::LangExt::rename_langext_code ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangExt::add_langext_code_alias ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangExt::delete_langext_code_alias ( CODE [,CODESET] ) These routines are all documented in the Locale::Codes::API man page.
