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 code：獲取所有關鍵標簽值。 你好123

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

獲得的輸出是[hello123] ，但我希望它同時顯示兩個（ [hello123, check123] ）

我如何獲得這個？

Answer 1

使用lxml和cssselect我會這樣做：

>>> 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，您可以通過以下方式進行操作：

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']

嘗試beautifulsoup包“ https://pypi.python.org/pypi/BeautifulSoup ”

Answer 4

使用xml.etree.ElementTree

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

    print resultlist

必須遍歷for循環中的“ key”標簽以獲得所需的結果。 上面的代碼解決了這個問題。
