我想從ElementTree Python中的簽名XML中讀取Signature,SignatureValue和SignedInfo,但它讀取爲None。 其他XML屬性讀取正常。我如何閱讀Signature,SignatureValue和SignedInfo?Python elementtree查找函數讀取簽名爲空(無)
這裏是我的代碼片段:
xml_file = open(settings.STATIC_ROOT + '/file/test.xml', 'rt').read()
response_xml = xml_et.fromstring(xml_file.encode('utf-8'))
print response_xml.find('Signature') # prints None
print response_xml.find('SignatureValue') # prints None
print response_xml.find('SignedInfo') # prints None
print response_xml.find('OrderID').text # works fine
這裏是我的測試XML:
<?xml version="1.0" encoding="UTF-8"?>
