I have a need to read "slices" out of a text file (a Makefile), based on known values that appear within the file. For example:
YACCCOMPILE = $(YACC) $(YFLAGS) $(AM_YFLAGS)
LTYACCCOMPILE = $(LIBTOOL) $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS)
+ \
--mode=compile $(YACC) $(YFLAGS) $(AM_YFLAGS)
YLWRAP = $(top_srcdir)/ylwrap
SOURCES = $(libpiuserland_la_SOURCES) $(pilot_addresses_SOURCES)
+ \
$(pilot_clip_SOURCES) $(pilot_csd_SOURCES)
+ \
$(pilot_debugsh_SOURCES) $(pilot_dedupe_SOURCES)
+ \
$(pilot_dlpsh_SOURCES) $(pilot_file_SOURCES)
+ \
$(pilot_foto_SOURCES) $(pilot_foto_treo600_SOURCES)
+ \
$(pilot_foto_treo650_SOURCES) $(pilot_getram_SOURCES)
+ \
$(pilot_getrom_SOURCES) $(pilot_getromtoken_SOURCES)
+ \
$(pilot_hinotes_SOURCES) $(pilot_install_datebook_SOURCES)
+ \
$(pilot_install_expenses_SOURCES)
+ \
$(pilot_install_hinote_SOURCES) $(pilot_install_memo_SOURCES)
+ \
$(pilot_install_netsync_SOURCES) $(pilot_install_todo_SOURCES)
+ \
$(pilot_install_todos_SOURCES) $(pilot_install_user_SOURCES)
+ \
$(pilot_memos_SOURCES) $(pilot_nredir_SOURCES)
+ \
$(pilot_read_expenses_SOURCES) $(pilot_read_ical_SOURCES)
+ \
$(pilot_read_notepad_SOURCES) $(pilot_read_palmpix_SOURCES)
+ \
$(pilot_read_screenshot_SOURCES) $(pilot_read_todos_SOURCES)
+ \
$(pilot_read_veo_SOURCES) $(pilot_reminders_SOURCES)
+ \
$(pilot_schlep_SOURCES) $(pilot_wav_SOURCES)
+ \
$(pilot_xfer_SOURCES)
RECURSIVE_TARGETS = all-recursive check-recursive dvi-recursive
+ \
html-recursive info-recursive install-data-recursive
+ \
install-dvi-recursive install-exec-recursive
+ \
install-html-recursive install-info-recursive
+ \
install-pdf-recursive install-ps-recursive install-recursive
+ \
installcheck-recursive installdirs-recursive pdf-recursive
+ \
ps-recursive uninstall-recursive
In this example, I want everything from ^SOURCES until the beginning of the next "block" that starts with ^RECURSIVE_TARGETS.
I know what my ^MARKERS will be in-advance, but I don't know how many lines will follow them until the next section that begins with another marker I may or may not need.
One of the problems is that there can be any number of spaces/tabs in the middle of, or at the end of each "continuation" line (or no continuation delimiters at all), and the "block" can be continued for anywhere from 1 line to dozens of lines.
Any idea how I would approach this problem in a clean, simplistic way? Is there enough detail provided here to understand my problem?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
