Hi,
I am trying to parse the data out of am XML file. The file is below.
Most of the data is easily grabbed but the keywords stretch over
several newlines and there can anywhere between 0 and 20 entries. I
have tried using /m and /s but these don't seem to work. I have set
$/="<image>", I don't know if this is impacting on my attempts. But
changing it does help either.
Here is what I am using at the moment:
==============
my $datafile = "news.xml";
open(FH,$datafile)|| die "Can't open $datafile: $!\n";
while (defined($i=<FH>)) {
$/ = </image>;
if ( $i =~ /\?xml version*/ ) {
next;
}
(my $splnum) = ($i =~ /<image number=.(\w\d+\/\d+)/i);
(my $title) = ($i =~ /<title>(.*)<\/title>/);
(my $date ) = ($i =~ /<date>(.*)<\/date>/);
(my $credit) = ($i =~ /<credit>(.*)<\/credit>/);
(my $caption) = ($i =~ /<caption>(.*)<\/caption>/);
(my $keywords) = ($i =~ /<keyword>(.*)<\/keyword>/);
chomp($splnum,$title,$date,$credit);
print "$splnum $title $date $credit $keywords\n";
}
===============
This only grabs the first keyword (NERVE FIBRE, OVERLAPPING) and I
need them all. Also the processing seems to stop after to records
when there are 470 in $datafile!!. I can't work that out either.
Any ideas? There are a lot of xml modules out there butI don't know if
any would help.
Thanx.
Dp.

SCIENCE PHOTO LIBRARY Nerve fibres. Coloured scanning electron
micrograph (SEM) of overlapping nerve fibres. Each fibre is made up
of several individual axons. An axon is a long extension from a nerve
cell (or neurone) which is the main output process of the cell. Some
small neurone cell bodies (rounded) can be seen here alongside the
axons. Nerve fibres rapidly relay signals between the central nervous
system (the brain and spinal cord) and muscles and organs in the
body. This allows the body to react quickly to any situation.
