Trying to construct a book database at home using information extracted from Amazon's web service. Everything works (transformxml, importxml) when I save the Amazon xml file to my computer, i.e.

transformxml "d:\bookdata.xml", "d:\bookdata.xsl", "d:\bookdata_mod.xml", true

BUT problems occurs when I try to transformxml the webpage directly, i.e.
transformxml "http://webservice.amazon.....", "d:\bookdata.xsl", "d:\bookdata_mod.xml", true

According to Microsoft, transformxml should work with "http://", but everytime I run it I keep getting "Run-time error '31527': Path not found:http://webservices...."

Incidentally, ImportXML works with the URL.

Any suggestions?
