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.

xdbegetvisualinfo

XdbeGetVisualInfo(3)						    X FUNCTIONS 					      XdbeGetVisualInfo(3)

NAME

       XdbeGetVisualInfo - Get dbe Visual Informations

SYNOPSIS

       #include <X11/extensions/Xdbe.h>

       XdbeScreenVisualInfo *XdbeGetVisualInfo(
	   Display  *dpy,
	   Drawable *screen_specifiers,
	   int	    *num_screens)

DESCRIPTION

       This function returns information about which visuals support double buffering.	The argument num_screens specifies how many elements there
       are in the screen_specifiers list.  Each drawable in screen_specifiers designates a screen  for	which  the  supported  visuals	are  being
       requested.   If	num_screens  is zero, information for all screens is requested.  In this case, upon return from this function, num_screens
       will be set to the number of screens that were found.  If an error occurs, this function returns NULL, else it returns a pointer to a  list
       of  XdbeScreenVisualInfo  structures  of  length  num_screens.  The nth element in the returned list corresponds to the nth drawable in the
       screen_specifiers list, unless num_screens was passed in with the value zero, in which case the nth element in  the  returned  list  corre-
       sponds to the nth screen of the server, starting with screen zero.  The XdbeScreenVisualInfo structure has the following fields:

	    int 	   count
	    XdbeVisualInfo *visinfo

       count specifies the number of items in visinfo.	visinfo specifies a list of visuals, depths, and performance hints for this screen.

       The XdbeVisualInfo structure has the following fields:

	    VisualID visual
	    int      depth
	    int      perflevel

       visual specifies one visual ID that supports double-buffering.  depth specifies the depth of the visual.  perflevel is a performance hint.

       The  only operation defined on a perflevel is comparison to a perflevel of another visual on the same screen.  The visual having the higher
       perflevel is likely to have better double-buffering graphics performance than the visual  having  the  lower  perflevel.   Nothing  can	be
       deduced from the following: the magnitude of the difference of two perflevels, a perflevel value in isolation, or comparing perflevels from
       different servers.

ERRORS

       BadDrawable
	      One or more values passed in screen_specifiers is not a valid drawable.
