python中的xml文件解析

Question

xml文件：

<global>
    <rtmp>
        <fcsapp>
            <password>
                <key>hello123</key>
                <key>check123</key>
            </password>
        </fcsapp>
    </rtmp>
</global>

python代码:获取所有key标签值。hello123 check123

using xml.etree.ElementTree

for streams in xmlRoot.iter('global'):
    xpath = "/rtmp/fcsapp/password"
    tag = "key"
    for child in streams.findall(xpath):
        resultlist.append(child.find(tag).text)

    print resultlist

获得的输出是[hello123]，但我希望它同时显示这两个输出([hello123, check123])

如何获取此信息？

Answer 1

使用lxml和cssselect，我会这样做：

>>> from lxml.html import fromstring
>>> doc = fromstring(open("foo.xml", "r").read())
>>> doc.cssselect("password key")
[<Element key at 0x7f77a6786cb0>, <Element key at 0x7f77a6786d70>]
>>> [e.text for e in  doc.cssselect("password key")]
['hello123 \n                      ', 'check123 \n                  ']

Answer 2

使用lxml和xpath，您可以通过以下方式完成此操作：

from lxml import etree

xml = """
<global>
    <rtmp>
        <fcsapp>
            <password>
                <key>hello123</key>
                <key>check123</key>
            </password>
        </fcsapp>
    </rtmp>
</global>
"""

tree = etree.fromstring(xml)
result = tree.xpath('//password/key/text()')
print result #  ['hello123', 'check123']
