In case you didn't get an answer yet: I don't know about the OP's stack trace, but the standard library accesses the internet in xml.sax.saxutils.prepare_input_source, which in turn may be called from xml.sax.expatreader.ExpatParser.external_entity_ref (unless the feature_external_ges is off). That, in turn, is called by the parser when it sees the DOCTYPE declaration. The OP was referring to validation, so more likely he was talking about the xmlproc parser (which is only in PyXML). I also agree with Mike Brown: The author of this W3C article apparently confuses a number of things, in particular whether an XML parser *should* fetch the SYSTEM identifier in a document. According to the XML spec, it should indeed. Now, the other question is whether there should be caching; and yes, there should be, and no caching is implemented (except in xmlproc, which supports catalogs). As for accessing URLs that are used as namespace URIs: our XML libraries never do that. In any case, AMK created issue2124.
