Re: Unparsed-text-available returns true for XML files

I use base-uri(/)  and the sub-string functions to distinguish file type.

I've got a situation where I've got a number of files I need to transform. I don't know what kind of files they are going to be (they are anything from an enumerated list of file types, but can be anything from .mdb to .sql to .xml to .xls and so on). So, I need to test the file type and then process them accordingly.
I thought the way to do this was to have unparsed-text() handle unparsed text and have document() handle everything else - by attaching the appropriate URI Resolver. Then, if unparsed-text-available() returns true, I can send the file data to a named template to handle appropriately and if document-available() returns true, I can send to a matched template to do what it needs to do.
But, I've just discovered that unparsed-text-available() will return true for xml files. So, I don't know how to distinguish within my xslt which files are unparsed and which ones aren't.
I could use some guidance here, please.
