Wouldn't it be possible to write something along the line
(in "rss.xml"
(while
(from
"<status>"
"<feed>"
"<feedburner>"
"<moreTags>" )
(case @
("<status>"
...
'twitter> )
("<feed>"
...
("<feedburner>"
...
The individual clauses of 'case' could call 'till' (possibly several
times in a loop) to collect the contents, and perhaps call 'match' on
the pieces.
A typical example for such a parser is the "lib/scrape.l" GUI scraper.
BTW, did you try a 'ulimit -s unlimited'? Just to be sure that a stack
overflow was the reason for the segfault, and not a 64-bit bug.
I have to explain that while the 32-bit version calls setrlimit() to set
an unlimited stack size, the 64-bit version does not. I think it should
not be the business of the interpreter to set such a limit, this can be
done more flexibly and transparently by the calling shell.
