i really just need some basic s/w engring architecting guidance... when i say 'architecting' -- i mean pseudo-code/stmts i can go after in the Perl book i have... and hopefully online examples...

i'm using Perl and i'm trying to parse Medline/Pubmed file paths on a Unix system in order to finally pass the PMID from each path to a pmid2doi conversion website < http://www.pmid2doi.org/ > ...

the structure of each link is of the form... /xxxxx/xxxxx/xxxxx/xxxxx/xxxxx/UNC00000000000042/00223468/v45i3/S0022346809003820

--ls

18507872 main.pdf main.raw main.xml

where: 00223468 <-- this is the PMID

so far, in Perl, i've got something that looks like this... 

#!/bin/perl
use strict; 
use warnings;
use LWP::Simple;

# this is bash-like implementation of what i'm trying to do
for doi in `find . -name "*.xml" | awk -F\/ '{print $2}' `  #this extr
+acts the PMID
do
        echo  $doi
        wget http://www.pmid2doi.org/
done

[download]

the website < http://www.pmid2doi.org/ > requires inputting the PMID in order to get back the DOI...

this is what i need to get running in Perl... and i need a little help in architecting & implementing this...

given your development background, i'm grateful for any insights... or recommended sites for generating regular expressions in Perl...

thanks very much!

Additionally,

I see that http://www.pmid2doi.org/ says the REST API expects the http://www.pmid2doi.org/ PLUS the DOI value.

So I need to find some example Perl code that gets a REST value from a URL.

In REST I just prepare the URL as specified and then the returned result should be the value I want.
