Now I would like to extend this to a XSD file that includes many other files. In other words I have a directory of XSD files that I would like to use. The include statement look like this (the included file is referenced by its name): <?xml version="1.0"?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"> <xsd:include schemaLocation="base.xsd"/> <xsd:element name="Price"> ... ... some types defined in "base.xsd" are used here I am new to lxml so sorry in advance if the question does not make sense.
