{主}

使用下面的代码，我可以单值。但我想迭代xml文件，满足不同的条件：

 XML_NAMESPACE = '{http://xml.juniper.net/junos/15.1F5/junos-routing}'
        with open('version1.xml') as fd:
            mydict = fd.read()
        tree = etree.parse('version1.xml')
    node = tree.iter(tag='{}preference'.format(XML_NAMESPACE))
            print (next(node).text)

条件： 使用特定文本（例如BARCLAYS-csp.inet.0）迭代表，并仅在*

时查找值

尝试findall，iter（）。无法迭代所有表名值。
