Manipulating xml data with awk
Hi everyone,

I have a little bit of complicated task to finish with AWK. Here it is;
I have a data file in xml format which looks like this
Code:
<data>
a1 a2 a3 a4 a5
b1 b2 b3 b4 b5
c1 c2 c3 c4 c5
d1 d2 d3 d4 d5
e1 e2 e3 e4 e5
</data>

lets say each data block contains 5 rows and 5 columns, what I need to do is this;
I have a condition, and I need to find the row that satisfies this condition then
I need to add an extra field to each row whose value will be calculated using
the columns of the row that satisfies the condition as well as other columns in
other rows. As an example, lets say row "c" satisfies my condition, then I add
an extra field to data which will look like this
Code:
<data>
a1 a2 a3 a4 a5 a6
b1 b2 b3 b4 b5 b6
c1 c2 c3 c4 c5 c6
d1 d2 d3 d4 d5 d6
e1 e2 e3 e4 e5 e6
</data>

where the last fields are calculated as following;
Code:
a6 = c2*a2 + c3*a3 + c4*a4 + c5*a5
b6 = c2*b2 + c3*b3 + c4*b4 + c5*b5
c6 = c2*c2 + c3*c3 + c4*c4 + c5*c5
d6 = c2*d2 + c3*d3 + c4*d4 + c5*d5
e6 = c2*e2 + c3*e3 + c4*e4 + c5*e5

the algebra on the above calculation may not necessarily be simple as this.

Thanks for any help.

locale::codes::langfam5.18

Locale::Codes::LangFam(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangFam(3pm)

NAME

       Locale::Codes::LangFam - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangFam;

	  $lext = code2langfam('apa');		       # $lext gets 'Apache languages'
	  $code = langfam2code('Apache languages');    # $code gets 'apa'

	  @codes   = all_langfam_codes();
	  @names   = all_langfam_names();

DESCRIPTION

       The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
       ISO 639-5.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
       language family codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language families. 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 = code2langfam('apa','alpha');
	  $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.

	   This is the default code set.

ROUTINES

       code2langfam ( CODE [,CODESET] )
       langfam2code ( NAME [,CODESET] )
       langfam_code2code ( CODE ,CODESET ,CODESET2 )
       all_langfam_codes ( [CODESET] )
       all_langfam_names ( [CODESET] )
       Locale::Codes::LangFam::rename_langfam  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangFam::add_langfam  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangFam::delete_langfam  ( CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangFam::delete_langfam_alias  ( NAME )
       Locale::Codes::LangFam::rename_langfam_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::delete_langfam_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
