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.

NAME

       Perl::Critic::Statistics - Compile stats on Perl::Critic violations.

DESCRIPTION

       This class accumulates statistics on Perl::Critic violations across one or more files.  NOTE: This class is experimental and subject to
       change.

INTERFACE SUPPORT

       This is considered to be a non-public class.  Its interface is subject to change without notice.

METHODS

       "new()"
	   Create a new instance of Perl::Critic::Statistics.  No arguments are supported at this time.

       " accumulate( $doc, @violations ) "
	   Accumulates statistics about the $doc and the @violations that were found.

       "modules()"
	   The number of chunks of code (usually files) that have been analyzed.

       "subs()"
	   The total number of subroutines analyzed by this Critic.

       "statements()"
	   The total number of statements analyzed by this Critic.

       "lines()"
	   The total number of lines of code analyzed by this Critic.

       "lines_of_blank()"
	   The total number of blank lines analyzed by this Critic. This includes only blank lines in code, not POD or data.

       "lines_of_comment()"
	   The total number of comment lines analyzed by this Critic. This includes only lines whose first non-whitespace character is "#".

       "lines_of_data()"
	   The total number of lines of data section analyzed by this Critic, not counting the "__END__" or "__DATA__" line. POD in a data section
	   is counted as POD, not data.

       "lines_of_perl()"
	   The total number of lines of Perl code analyzed by this Critic. Perl appearing in the data section is not counted.

       "lines_of_pod()"
	   The total number of lines of POD analyzed by this Critic. Pod occurring in a data section is counted as POD, not as data.

       "violations_by_severity()"

       "violations_by_policy()"
	   The number of violations of each policy found by this Critic as a reference to a hash keyed by full policy name.

       "total_violations()"
	   The the total number of violations found by this Critic.

       "statements_other_than_subs()"
	   The total number of statements minus the number of subroutines.  Useful because a subroutine is considered a statement by PPI.

       "average_sub_mccabe()"
	   The average McCabe score of all scanned subroutines.

       "violations_per_file()"
	   The total violations divided by the number of modules.

       "violations_per_statement()"
	   The total violations divided by the number statements minus subroutines.

       "violations_per_line_of_code()"
	   The total violations divided by the lines of code.
