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.

MALAGA(1)						      Malaga quick reference							 MALAGA(1)

NAME

       malaga - natural-language word and sentence analysis

SYNOPSIS

       malaga [-morphology|-syntax] [-quoted] [-input input] project-file

DESCRIPTION

       Malaga  is a development environment for natural-language grammars based on the Left-Associative Grammar formalism.  Malaga grammars can be
       used for automatic morphological and/or syntactic analysis.

       The program malaga is Malaga's user interface for analysing word forms and sentences, displaying the results and finding bugs in a grammar.

       malaga requires the name of a language-dependent project-file as a command-line argument.

       If no command line options are given, malaga starts in interactive mode, and you can enter commands.  If you are not sure about the name of
       a command, use the command help to get an overview of all malaga commands.

       If you want to quit malaga, enter the command quit.

       See info Malaga for details.

OPTIONS

       -h[elp]
	      Print a help text about malaga's command line arguments and exit.

       -i[nput] input
	      Analyse a single word or sentence given as command line argument (only valid in morphology or syntax mode).

       -m[orphology]
	      Start malaga in morphology mode.	In this mode word forms are read in from the standard input stream and analysed (one word form per
	      line). The analysis result are written to the standard output stream.

       -q[uoted]
	      The input lines to be analysed are quoted (only valid in morphology or syntax mode).

       -s[yntax]
	      Start malaga in syntax mode.  In this mode sentences are read in from the standard input	stream	and  analysed  (one  sentence  per
	      line). The analysis result is written to the standard output stream.

       -v[ersion]
	      Print malaga's version number and exit.
