Thanks to you both for your replies. I was trying to keep it simple, but I should've added more information, I think. Here goes:

The data come from a LaTeX file, which uses a package called "Expex" which formats interlinear analyses of a non-English language.

The following two examples show how the data is laid out. The first line "\gla" is the object language, the second line "\glb" is the underlying form, the third line "\glc" is the morpheme gloss, the fourth line "\glc" is the word translation (the package doesn't allow "\gld" for whatever reason), and the last line "\glft" is the sentence translation. As you see, the number of words varies from example to example, just as natural language sentences may be shorter, or longer.

Each "word" is enclosed in curly brackets in the first two lines (though other sets of curly brackets may be nested within words), but only separated by spaces in the second two lines. The curly brackets are necessary to delimit words in the first two lines since some latex commands (e.g. "\ts" below) require blank spaces after them.

Code:
\gla {itl\'i\textglotstop } {k\textsuperscript{w}uk\textsuperscript{w}} {t\textschwa cx\textsuperscript{w}\'u\texthalflength\texthalflength y.}// 
\glb {itl\'i\textglotstop } {k\textsuperscript{w}uk\textsuperscript{w}} {tc+\ts x\textsuperscript{w}\'uy}//
\glc \textsc{dem} \textsc{rep} \textsc{loc}+go //
\glc from.there they.say came.over.this.way //
\glft `They said he was coming along.' //

\gla {u\textbeltl } {cut} {k\textsuperscript{w}uk\textsuperscript{w}} {al\'a\textglotstop } {lut} {i\textglotstop } {q\'aqx\textsuperscript{w}\textschwa lx} {ka\textglotstop} {cx\textsuperscript{w}uys} {i\textglotstop } {l} {siw\textbeltl k\textsuperscript{w}.} //
\glb {u\textbeltl } {cut} {k\textsuperscript{w}uk\textsuperscript{w}} {al\'a\textglotstop } {lut} {i\textglotstop } {q\'a(\tb)\ts qx\textsuperscript{w}lx} {ki\textglotstop} {c\textendash \ts x\textsuperscript{w}uy\textendash s} {i\textglotstop } {l} {siw\textbeltl k\textsuperscript{w}} //
\glc \textsc{conj} say \textsc{rep} \textsc{dem} \textsc{neg} \textsc{det} fish \textsc{comp.obl} \textsc{cust}\textendash go\textendash \textsc{3sg.poss} \textsc{det} \textsc{loc} water //
\glc and he.said they.say here no the fish where.that they.come the through water //
\glft `Coyote said there will be no fish going through the water here.' //

The \glft line may be ignored, but what I'd like exactly is the following, where "&" denotes a column separator in LaTeX and "\\" indicates a newline. Each line has 4 "words", i.e. the nth word in each of the first four lines in the examples above.

Code:
{itl\'i\textglotstop } & {itl\'i\textglotstop } & \textsc{dem} & from.there \\
{k\textsuperscript{w}uk\textsuperscript{w}} & {k\textsuperscript{w}uk\textsuperscript{w}} &  \textsc{rep} & they.say \\

Etcetera. Once the first example is done, the second example would be appended to the above list. Eventually each line will be sorted alphabetically by the first "column". It'd also be nice to be able to choose which input lines to include in the output, though I'd greatly appreciate any more assistance you could give in obtaining the basic result just outlined. Thanks again.

trans

trans(1)						      General Commands Manual							  trans(1)

NAME

       trans - translation tool for use with source message catalogs

SYNOPSIS

       trans [-c] [-o name] file.msg

OPTIONS

       Display comment lines beginning with a dollar sign ($) for translation, in addition to messages.  Call the output file name. The default is
       output file name is trans.msg.

DESCRIPTION

       The trans command assists in the translation of source message catalogs.  The command reads input from file.msg and writes  its	output	to
       either  a file named trans.msg or a file you name on the command line.  The command displays file.msg in a multiple window screen that lets
       you simultaneously see the original message, the translated text you enter, and any messages from the trans command.  This multiple  window
       screen is easier to use for translating messages than a single window screen.

       The top window in the multiple window screen displays the text in the message source file file.msg. The editor displays the current message
       in reverse video.

       In the center window, trans displays a prompt that asks you to enter a translated message.  You use a control key editor to move the cursor
       and delete text in the center window. The control key sequences are defined as follows:

       ------------------------------------------
       Key Sequence   Meaning
       ------------------------------------------
       CTRL/k	      Display control key help
       CTRL/h	      Back space
       CTRL/l	      Forward space
       CTRL/w	      Back word
       CTRL/f	      Forward word
       CTRL/e	      Move to end of input
       CTRL/b	      Move to beginning of input
       CTRL/n	      Next line
       CTRL/p	      Previous line
       CTRL/u	      Delete input
       CTRL/i	      Insert mode (default)
       CTRL/r	      Replace mode
       DEL	      Delete previous character
       ------------------------------------------

       If you need to span more than one line with the translated text, type a backslash () and press the RETURN key to enable line continuation.
       After you finish entering the translated text, press the RETURN key to signal that you have finished translating that message.

       The bottom window displays any messages generated by trans. If an error occurs, trans prompts you to re-enter the  entire  line,  including
       the message label or number.

RESTRICTIONS

       Your terminal must be 80 columns by 24 lines for trans to display its three-window screen.

       You  cannot interrupt a trans session and restart it at the point you stopped. You must complete the all the changes to a file before exit-
       ing a file.
