KML HTML Description broken out to fields

I have been working on an issue for a few months to automate ‘Expose Attribute’ in such transformers as XMLXQueryExtractor. FME said it is on there development list, I/we have to crack open these HTML fields and type the Expose Attribute on average once a week. I have tried many gyrations, wanted to see if you have done this or have an idea how to automate. Many Thanks
