Re^2: 1GB XML mining with XML:twig (newbies question)

Thanks for both the replies. I solved the problem already by means offered by XML::twig. There is possiblity to read just a portion of the data (one PC-Compound), to parse and discard in the end - in principle it is similar to your suggestions in a way:

my $twig= new XML::Twig(
                    twig_handlers =>                  
                      { PC-Compound => \&subrutineforparsing}
                           );
    $twig->parsefile($inputfile);

As for several PC-InfoData_value_binary (aliases), I load the into an array and than use regular expression to get just the alias from NSC db. karpatov

Hmm. My solution worked. But was desperately slow and runout of memory errors happend. So I decided to use your strategy (Regex and only then xml-parser) and it is great. Tx. karpatov	[reply]
