[xsd-users] Problems with generated schema

[ope]

Hi,

I build a tree parser for the metalink schema at
http://www.metalinker.org/schema/3.0/metalink.xsd by:

xsd cxx-tree \
 --namespace-map http://www.metalinker.org/=metalink \
 --generate-ostream \
 --hxx-suffix .hpp \
 --cxx-suffix .cpp metalink.xsd

and use it in that manner:

---8<--- header ---8<---
    class metalink_parser {
    private:
        typedef
            std::vector<std::string>		metalink_files_t;
    ....
    private:
        metalink_files_t 			m_metalink_files;
        std::auto_ptr<metalink::metalinkType>	m_metalink;
    };
---8<--- header ---8<---

---8<--- source ---8<---
    // a simple test with the first entry
    const std::string metalink_file = m_metalink_files.front();

    try {
        // take ownership
        m_metalink = metalink::metalink(metalink_file);

        metalink::filesType::file::const_iterator
first(m_metalink->files().file().begin());
        metalink::filesType::file::const_iterator
last(m_metalink->files().file().begin());

        for (; first != last; ++first) {
            cout << *first;
        }
    }
    catch (const xml_schema::exception& e) {
        cerr << e << endl;
    }

---8<--- source ---8<---

and get a lot of errors:

element 'xs:element'
metalink.xsd:9:41 error: Unknown element 'xs:complexType'
metalink.xsd:9:41 error: Attribute 'name' is not declared for element
'xs:complexType'
...

What's gone wrong here?

Anyway, how can I rename the anonymous types with useful names other
than counted version1 (or hash1 by use of xsd 3.0.0b2)?

Thanks
