Thanks, turning the name of the xml file into a URL fixed that problem. This needs to be documented, and the catalog generator should be able to read the xml configuration file from the local filesystem (after all, I'm assuming it's reading the local file system anyway to collect the names of the data set files).
I'm having a couple further problems: 1) What does the (error or warning?) message below mean, and 2) the generator is adding datasets to the catalog that do not match the regular _expression_, and so have an empty string as their name attribute.
