Answer 1

如何使用lxml？

从文档：

>>> f = StringIO('''\ 
... <element name="a" xmlns="http://relaxng.org/ns/structure/1.0"> 
... <zeroOrMore> 
...  <element name="b"> 
...  <text /> 
...  </element> 
... </zeroOrMore> 
... </element> 
... ''') 
>>> relaxng_doc = etree.parse(f) 
>>> relaxng = etree.RelaxNG(relaxng_doc) 

>>> valid = StringIO('<a><b></b></a>') 
>>> doc = etree.parse(valid) 
>>> relaxng.validate(doc) 
True 

>>> invalid = StringIO('<a><c></c></a>') 
>>> doc2 = etree.parse(invalid) 
>>> relaxng.validate(doc2) 
False
