A co-worker recently used a sitemap generator to come up with a few thousand URLs from our website with generated changefreq and priority. Now, these are going to take ages to go through and manually set the changefreq and priority for, so I thought we need to find something that can do a Find-and-Replace that can set the changefreq and priority if the loc (URL) matches a specific string.
This seemed to me a fairly common requirement, but I couldn't find anything through Google. I guess somebody (me!!) would have to build a tool.
