Thank you.

I see, I didn't explain my problem in a clear way. The problem of your code is that the tag must come inside the range of RADIUS (you set it at 25) to be detected. That is fine, but not the goal of my implementation. What I need is to print out the concordance PLUS the last tag seen before finding that concordance (i.e. before matching the $query).

I'd like to put this information in a table "concordance of $query PLUS last tag seen before encountering $query".

That is why I was trying to change the module's code.

    I considered that that may be your requirement, but I thought there were too many unknowns for me to sensibly implement sample code. The most important is what should happen where the last tag seen may be associated with multiple concordance fragments? I chose to only consider tags within the current fragment. Another option would be to reuse a tag for all following fragments until a new tag is found, or a tag could be associated with the first following fragment, or the first following fragment so long as it is within some maximum distance of the tag.

    I would first split the text by tag entries, then perform the concordance match on each fragment:

    use strict; use warnings; use Lingua::Concordance; my $text = <<TEXT; Oldfield's career began fairly early, playing <1> acoustic guitar in l +ocal folk clubs. At this time, he already had two fifteen-minute instrumental pi +eces in which he would "go through all <2>sorts of moods", precursors to his l +andmark 1970s' compositions. In his early teens, Oldfield was involved in a 'b +eat group' <3>playing Shadows-style music (he has often cited Hank Marvin as a ma +jor influence, and would later cover The Shadows' song "Wonderful Land"). TEXT my $concordance = Lingua::Concordance->new(); $concordance->text($text); my @parts = split /\s*(<\d+>)\s*/, $concordance->text(); my @frags; unshift @parts, '' if $parts[0] !~ /^<\d+>$/; push @frags, map {$_->[0] =~ s/[<>]//; $_} [splice @parts, 0, 2] while + @parts; $concordance->query('in'); for my $fragment (@frags) { my ($tag, $fragText) = @$fragment; $concordance->text($fragText); print "$tag: $_\n" for $concordance->lines(); }

    It should be fairly trivial to modify the loop to meet whatever additional constraints you require.

    True laziness is hard work

      GrandFather, I thank you so much. This is exactly what I was looking for. It does the job perfecly.
