使用 pandas 读取 xml 文件

Question

I want to read an xml file to pandas. Here is sample XML file

<author lang="en" class="1">
    <documents>
        <document><![CDATA[Hellow how are you]]></document>
        <document><![CDATA[I am good]]></document>
        <document><![CDATA[What about you]]></document>
    </documents>
</author>

This is what I have tried

from xml.dom import minidom
xmldoc = minidom.parse('text.xml')
itemlist = xmldoc.getElementsByTagName('document')

But I don't know how to move ahead and get values from itemlist . When I print it, I for following output

[<DOM Element: document at 0x170c9b229d0>,
 <DOM Element: document at 0x170c9b22a60>,
 <DOM Element: document at 0x170c9b22af0>]

How can I get strings out of it?

Answer 1

I believe you need

import pandas as pd
from xml.dom import minidom
xmldoc = minidom.parse('text.xml')
itemlist = xmldoc.getElementsByTagName('document')

df = pd.DataFrame({"document": (i.firstChild.nodeValue for i in itemlist)})
print(df)

Output:

             document
0  Hellow how are you
1           I am good
2      What about you
