Tyler will cover his learning experiences creating the Parse::MediaWikiDump and MediaWiki::DumpFile modules which are made to handle the 24 gigabyte English Wikipedia dump files in a reasonable time frame.</p> <p> 1) Real world benchmarks of C and perl libraries used to process huge</p> <pre><code>XML documents. </code></pre> <p> 2) The dirty little secret about XS and what it means for you in this</p> <pre><code>context. </code></pre> <p> 3) The evolution of the implementation of a nice interface around event</p> <pre><code>oriented (SAX style) XML parsing. </code></pre> <p> 4) Why XML::LibXML::Reader and XML::CompactTree are your friends and</p> <pre><code>how to tame them. </code></pre> <p>As always, the meeting will be followed by social hour at the Lucky Lab.</p> </div> <h3>Links</h3> <ul> <li><a class="url u-url" href="http://pdx.pm.org">Website</a></li> </ul> </div>
