I tried doing this with just a regular expression but couldn't figure out
how. I was however able to do it quite easily with a text filter. The
following PERL example works for me to split the text and create and save
an individual file for each chapter.
Save the following in your text filters folder and run it against your
document.
--------------------------
#!/usr/bin/perl
# Read each line into a scaler, then print it back
my $fullstring;
while (<>) {
$fullstring .= $_;
print;
}
# split the scaler into an array
my @h2s = split( /<h2>/, $fullstring );
# Delete the first item of the array, which will be empty because our text
starts with "<h2>"
shift @h2s;
# add back the "<h2>" at the start of each array element
# which was removed when we did the split
foreach $string (@h2s) {
$string = "<h2>" . $string;
}
# Now the array contains each of your chapters, one per element.
# The following will create a new directory on your desktop called
"Chapters"
# (if it doesn't exist already) and save a new document with the text from
each
# chapter/array element. The original document will be the same as when it
started,
# because we printed each line back out after we read it.
my $counter = 1;
print `mkdir -p ~/Desktop/Chapters/`;
for (@h2s) {
open( CHAPTER, ">~/Desktop/Chapters/chapter$counter.html" );
print CHAPTER $_;
close(CHAPTER);
$counter++;
}
