Just found that for an example adapted from https://bugs.launchpad.net/lxml/+bug/1234114/comments/3 (xs:include instead of xs:import): ############## # test_schema.py XSD = b"""<?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"; xmlns:xlink="http://www.w3.org/1999/xlink"; xmlns="lxmltest" targetNamespace="http://www.w3.org/1999/xlink"; elementFormDefault="qualified" attributeFormDefault="unqualified"> <xs:include schemaLocation="http://www.loc.gov/standards/xlink/xlink.xsd"; /> </xs:schema> """ from lxml import etree parser = etree.XMLParser( load_dtd=True, no_network=True, huge_tree=True, resolve_entities=True) tree = etree.fromstring(XSD, parser=parser) schema = etree.XMLSchema(tree) print(schema) ############## I can successfully run this if the xs:include location is http but not https (the xlink.xsd is available both with https and http URLs). If I change it to https I get Traceback (most recent call last): File "test_schema.py", line 16, in <module> schema = etree.XMLSchema(tree) File "src/lxml/xmlschema.pxi", line 88, in lxml.etree.XMLSchema.__init__ lxml.etree.XMLSchemaParseError: Element '{http://www.w3.org/2001/XMLSchema}include': Failed to load the document 'https://www.loc.gov/standards/xlink/xlink.xsd' for inclusion., line 9 As I'm behind a proxy: I also just found out that while curl happily accepts http_proxy=my.proxy.address.net:8080 lxml (libxml2) only works if this is set to http_proxy=http://my.proxy.address.net:8080 i.e. with an explicit <scheme>:// Cheers, H.
