Pubmed notes

A simple way of fetching documents from pubmed, as actually used, for testing purposes anyway:

<?php
  $efetch_url = 'http://eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?db=pubmed&id=' . $pmid . '&retmode=xml';

// @debug
//  $efetch_load = simplexml_load_file($efetch_url);
// drupal_set_message('<pre>'.var_export($efetch_load,TRUE).'</pre>');
?>

This can be done with SOAP as well as the simpler way.

(Let us not forget the mythical nodalpoint pubmed module, which announced its triumphant return in the post "Pubmed module is back"... that was on 2003-05-12 unfortunately and, in addition to there being no code, none of the example links work anymore.)

Thanks to a tip from Alf Eaton of HubMed.org:

just put one of PubMed's filters in square brackets at the end of the search term, same as in the web interface.
"melancon b"[AU], for example.

Document Type Definition (DTD), could also call it XML Schema
