(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.

irsend

IRSEND(1)							   User Commands							 IRSEND(1)

NAME

       irsend - basic LIRC program to send infra-red commands

SYNOPSIS

       irsend [options] DIRECTIVE REMOTE CODE [CODE...]

DESCRIPTION

       Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such
       as TV boxes, HiFi sets, etc.

       DIRECTIVE can be:
	  SEND_ONCE	    - send CODE [CODE ...] once
	  SEND_START	    - start repeating CODE
	  SEND_STOP	    - stop repeating CODE
	  LIST		    - list configured remote items
	  SET_TRANSMITTERS  - set transmitters NUM [NUM ...]
	  SIMULATE	    - simulate IR event

       REMOTE is the name of a remote, as described in the lircd configuration file.

       CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file.

       NUM is the transmitter number of the hardware device.

       For the LIST DIRECTIVE, REMOTE and/or CODE can be empty:

	  LIST	 ""    ""   - list all configured remote names
	  LIST REMOTE  ""   - list all codes of REMOTE
	  LIST REMOTE CODE  - list only CODE of REMOTE

       The SIMULATE command only works if it has been explicitly enabled in lircd.

       -h --help
	      display usage summary

       -v --version
	      display version

       -d --device
	      use given lircd socket [/var/run/lirc/lircd]

       -a --address=host[:port]
	      connect to lircd at this address

       -# --count=n
	      send command n times

EXAMPLES

	  irsend LIST DenonTuner ""
	  irsend SEND_ONCE  DenonTuner PROG-SCAN
	  irsend SEND_ONCE  OnkyoAmpli VOL-UP VOL-UP VOL-UP VOL-UP
	  irsend SEND_START OnkyoAmpli VOL-DOWN ; sleep 3
	  irsend SEND_STOP  OnkyoAmpli VOL-DOWN
	  irsend SET_TRANSMITTERS 1
	  irsend SET_TRANSMITTERS 1 3 4
	  irsend SIMULATE "0000000000000476 00 OK TECHNISAT_ST3004S"

FILES

       /etc/lirc/lircd.conf
	      Default lircd configuration file.  It should contain all the remotes, their infra-red codes and the corresponding timing	and  wave-
	      form details.

DIAGNOSTICS

       If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics:
       "irsend: could not connect to socket"
       "irsend: Connection refused" (or "Permission denied").

SEE ALSO

       The documentation for lirc is maintained as html pages. They are located under html/ in the documentation directory.
