示例1: testNormalizedAfterLoad
# 需要导入模块: from xml import dom [as 别名]
# 或者: from xml.dom import getElementsByTagName [as 别名]
def testNormalizedAfterLoad(self):
"""
Introduced this test on jython because
1. Cpython guarantees, by the use of xml.dom.expatbuilder,
that all text nodes are normalized after loading.
2. Jython has no expat, and thus uses xml.dom.pulldom.parse
(which uses any java SAX2 compliant parser), and which makes
no guarantees about text node normalization.
Thus we have to check if text nodes are normalized after a parse.
