in reply to XML::DOM extracting digits between 2 tags

I haven't worked with XML::DOM before (I usually use XML::Smart), but here's a working example that extracts the zipcode field from the example data you provided:
use strict; use warnings; use XML::DOM; my $xml = ''; $xml .= $_ for <DATA>; my $parser = XML::DOM::Parser->new; my $doc = $parser->parse($xml); my $result_list = $doc->getElementsByTagName('Result'); my $result_count = $result_list->getLength; for my $result_n (0..($result_count - 1)) { my $result = $result_list->item($result_n); my $zip_nodes = $doc->getElementsByTagName('Zip'); my $zip = $zip_nodes->item(0)->getChildNodes->item(0)->getData; print "zipcode: $zip\n"; } __DATA__ <?xml version="1.0" encoding="UTF-8"?> <ResultSet> <Result precision="address"> <Latitude>37.416384</Latitude> <Longitude>-122.024853</Longitude> <Address>701 FIRST AVE</Address> <City>SUNNYVALE</City> <State>CA</State> <Zip>94089-1019</Zip> <Country>US</Country> </Result> </ResultSet>
It should have some additional error handling for malformed documents, but that's easy enough to add.

[Corion]: Meh. I need to find myself a better "programming" feed than r/programming (which is just HackerNews reposts and advertisements, very little code). Maybe I should select a list of links that I liked on r/programming and then google for ...
[Corion]: ... an aggregator site that also listed (ideally) all of these links once. And maybe also have an exclude list to blacklist some of the most spammy links that the site may have never mentioned at all
[marto]: I gave up reading HN at all, and feel much better for it :P
[Corion]: Now, how to best automate that Google search ... :-)
[Corion]: marto: Yeah, I'm also short of not reading it at all. I already stopped reading it in the morning because it gave me a foul mood.
[Corion]: The good posts on HN are the non-computing posts. Most of the other stuff is maybe relevant to you if you are 20 and live in Silicon Valley...
[Corion]: Two attributes that don't describe me.
[Corion]: Maybe I should also write a curator for HN or simply not read it anymore, like you do.
