从XML到Python列表的数据

Question

是否可以将XML文件中的数据存储到python中的列表中.例如,我有一个包含以下内容的XML文件:

<brochure>
<onlinePath>http://EEE</onlinePath>
<downloadPath>http://YYY</downloadPath>
<Name>ABC</Name>
<AAA>
    <P>JPG</P>
        <Q>JPG</Q>
</AAA>
</brochure>
<brochure>
<onlinePath>http://EKK</onlinePath>
<downloadPath>http://XXX</downloadPath>
<Name>DEF</Name>
<AAA>
    <P>JPG</P>
        <Q>JPG</Q>
</AAA>
</brochure>

是否可以存储到python列表中,如:

onlinePath = ("http://EEE", "http://EKK")
Name = ("ABC", "DEF")

Answer 1

import lxml

xml = """
<brochures>
    <brochure>
        <onlinePath>http://EEE</onlinePath>
        <downloadPath>http://YYY</downloadPath>
        <Name>ABC</Name>
        <AAA>
            <P>JPG</P>
            <Q>JPG</Q>
        </AAA>
    </brochure>
    <brochure>
        <onlinePath>http://EKK</onlinePath>
        <downloadPath>http://XXX</downloadPath>
        <Name>DEF</Name>
        <AAA>
            <P>JPG</P>
            <Q>JPG</Q>
        </AAA>
    </brochure>
</brochures>
"""

root = lxml.etree.fromstring(xml)
mylist = root.xpath('//brochure/onlinePath/text()')

结果是

['http://EEE', 'http://EKK']

笔记:

1. 我将你的xml包装在<brochures> </ brochures>中,使其成为树而不是森林(即单根节点);

2. 如果要从文件而不是字符串中读取,请使用lxml.etree.parse()而不是lxml.etree.fromstring()
