我试图用这个注册命名空间:
ET.register_namespace("inv", "http://www.stormware.cz/schema/version_2/invoice.xsd")
但它不起作用:
Traceback (most recent call last):
File "C:\tutorial\temp_xml2.py", line 34, in module>
for listInvoice in root.findall('inv:invoiceHeader'):
File "C:\Python27\LIB\xml\etree\ElementTree.py", line 390, in findall
return ElementPath.findall(self, path, namespaces)
File "C:\Python27\LIB\xml\etree\ElementPath.py", line 293, in findall
return list(iterfind(elem, path, namespaces))
File "C:\Python27\LIB\xml\etree\ElementPath.py", line 259, in iterfind
token = next()
File "C:\Python27\LIB\xml\etree\ElementPath.py", line 83, in xpath_tokenizer
raise SyntaxError("prefix %r not found in prefix map" % prefix)
SyntaxError: prefix 'inv' not found in prefix map
>>>
这有什么问题?
谢谢马丁尼
我试过 - 1.:
for listInvoice in root.findall('inv:invoiceHeader', namespaces=dict(inv='http://www.stormware.cz/schema/version_2/invoice.xsd')):
invoiceHeader = listInvoice.find('inv:id', namespaces=dict(inv='http://www.stormware.cz/schema/version_2/invoice.xsd')).text
print invoiceHeader
结果:(空)
2.:
nsmap=root.nsmap
print nsmap
结果:AttributeError:“元素”对象没有属性“nsmap”
3.:
for listInvoice in root.findall('.//{http://www.stormware.cz/schema/version_2/invoice.xsd}invoiceHeader'):
invoiceHeader = listInvoice.find('.//{http://www.stormware.cz/schema/version_2/invoice.xsd}id').text
print invoiceHeader
结果:工作正常。
有没有机会一次注册命名空间?然后我想使用 listInvoice.find('inv:id').text 而不是 listInvoice.find('.//{http://www.stormware.cz/schema/version_2/invoice.xsd}id') .text(更好的代码且易于阅读)
