Answer 1

This is because the Microsoft XML Parser does not know to handle your DOCTYPE when only the Public identifier is specified.
It's trying to open the dtd resource
specified in the SYSTEM identifier
which in your example is "", the empty
string.
I changed your:
<!DOCTYPE article PUBLIC "-//Davenport//DTD DocBook V3.0//EN" "" [
to:
<!DOCTYPE article PUBLIC "-//Davenport//DTD DocBook V3.0//EN" "file:/C:/docbook/docbookx.dtd" [
And was able to eliminate your parse error.
However, your XSL file is not XSLT 1.0 compliant and it's not Microsoft-XSLT-in-IE5 compliant (from the December 1998 working draft), so I don't expect the XSL part of what you're trying to do will work.
