#[unsafe(no_mangle)]
pub unsafe extern "C" fn xmlTextReaderGetAttributeNs(
    reader: *mut XmlTextReader,

) -> *mut xmlChar

Get an attribute value by local name and namespace URI.

UPSTREAM-PARITY

xmlChar *xmlTextReaderGetAttributeNs(xmlTextReaderPtr reader,
                                     const xmlChar *localName,
                                     const xmlChar *namespaceURI);

Safety

reader, localName, and namespaceURI must be valid pointers or NULL.
