WebArchive Extractor is a utility to extract Apple’s WebArchve format (created by saving web pages with Safari, or with TextEdit). The extracted files can be published on the web directly, within another web application, or used as desktop application help files – whew that was a mouth full.
On top of a few bug fixes, this version adds the ability to export to plain HTML. By default WebArchive Extractor exports to XHTML / XML which is good, but the XML processing instruction can cause problems if you include the extracted content into a PHP file (or any XML processing instruction sensitive system).
Another addition is the Asset URL setting. If you put a URL in that field, the URL will be put before all assets on the generated page. So, for example, if the document has yadda.gif in it, and you put http://yadda.com/images/ as the Asset URL, the exported image tag source attribute will be http://yadda.com/images/yadda.gif. (helpful if you want images in a different directory).
I also added help (not that the application is that complicated, but it just kind of rounds it out).
If you already have WebArchive Extractor installed, you can get the new version with the built in software update (in the menu WebArchive Extractor -> Check For Updates…). You can also download the newest version from the project page.
