(n)awk: print regex search output lines in one line
Hello.
I have been looking high and low for the solution for this. I seems there should be a simple answer, but alas.

I have a big xml file, and I need to extract certain information from specific items. The information I need can be found between a specific set of tags. let's call them <tag></tag>. Doing a regex lookup yields 4 lines of text, which I need to be 1 line, and this has to happen with every snippet that's between those tags (about 700 or so <tag></tag> elements in the xml file).

So, if I do this:
Code:
awk -F"tag" '/ref1/;/ref2/;/ref3/;/ref4/ {print}' file.xml

the output I get is:
Code:
<ref1="this is ref1"/>
<re2="this is ref2" />
<ref3="this is ref3" />
<ref4="this is ref4 />
<ref1="this is ref1"/>
<re2="this is ref2" />
<ref3="this is ref3" />
<ref4="this is ref4 />
. . .

The output I need:
Code:
<ref1="this is ref1"/><re2="this is ref2" /><ref3="this is ref3" /><ref4="this is ref4 />
<ref1="this is ref1"/><re2="this is ref2" /><ref3="this is ref3" /><ref4="this is ref4 />
. . .

Note: I am in a very secure environment, so I cannot install anything, so I only have the regular awk/nawk/gawk and sed that comes with Solaris 11.

Any help would be greatly appreciated.

locale::codes::langfam

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

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.
