Last night I realized there was one more step needed to restore my 2002-2006 archive. All of my references into that archive from this blog, which started in December 2006, had to be redirected. What’s more, they had to be remapped. Old URLs like http://weblog.infoworld.com/udell/2006/12/04.html#a1571 had to become new URLs like http://jonudell.net/udell/2006-12-04-hunting-the-elusive-search-strategy.html.
Even without the remapping, it’s not obvious how to do a simple search and replace (say, from weblog.infoworld.com/udell to jonudell.net/udell) across a set of blog entries. I tried the export/edit/import route, but — at least in the case of WordPress — that doesn’t seem to be a way to update existing stuff.
So I wound up writing a script that uses the MetaWeblog API to fetch my current blog entries, find references to the old namespace, adjust them to point to the new namespace, and update the entries. It’s here for my own future reference, and for yours if you need it.
As always in these situations, I end up wondering what a civilian would do. Blog publishing systems don’t seem have bulk search-and-replace capability. They do, however, have APIs. There could be a tool or service that helps people make these kinds of changes. It’d be hard to avoid the password anti-pattern, so if this were a cloud-based service rather than a locally-installed tool you’d want to change your password after using it. But still, it should be doable.
Do such tools or services exist?
