dtd-parsing

问题 I'm learning XML at the moment and I'm struggling with the first DTD extension. My DTD : <!ELEMENT biblio (livre*) > <!ELEMENT livre (achat , auteurs, titre ) > <!ATTLIST livre langue CDATA #IMPLIED ref CDATA #IMPLIED> <!ELEMENT achat EMPTY > <!ATTLIST achat date CDATA #IMPLIED lieu CDATA #IMPLIED> <!ELEMENT titre (#PCDATA)> <!ATTLIST titre genre CDATA #IMPLIED type NMTOKEN #IMPLIED> <!ELEMENT auteurs (auteur+) > <!ELEMENT auteur ( nom?, prenom? ,sexe?) > <!ELEMENT nom (#PCDATA)> <!ELEMENT

问题 I have made custom xhtml valdidator in .NET(validating through dtd + some extra rules) and I have noticed a discrepancy between my validation and w3c validation. In my validator I get the following error when there is colon in the id (let's say : id="mustang:horse") (Error) The 'id' attribute has an invalid value according to its data type. But I do not get any errors on w3c for this pattern. I tried to find a list of invalid characters for an attribute in xml/xhtml but couldn't find it?

问题 I need your help. I use lxml library to parsing dtd file. How can i get c subexpression in this example? dtd = etree.DTD(StringIO('<!ELEMENT a (b,c,d)>')) I try this content = dtd.elements()[0].content left, right = content.left, content.right but it left of right subexpression. http://lxml.de/validation.html#id1 回答1: I'm completely guessing (I've never touched this before) but: from io import StringIO from lxml import etree dtd.elements()[0].content.right.left #>>> <lxml.etree.
