python - 在Python中添加父节点编号关系的表格XML文件

Question

我有以下代码尝试解析 XML 文件并转换为表格形式。

import xml.etree.ElementTree as ET
tree = ET.parse('smp.xml')
root = tree.getroot()

for text in root.iter('text'):
    print(text.attrib)

for text in root.iter('text'):
    print(text.text)

下面是我到目前为止得到的输出，但与我想要的输出相去甚远，因为我是 python 的新手，并且我不知道如何组织这些输出以显示表格，并另外将 page、row 和 column 父级的列添加到左侧元素对应于每个文本/属性:

>>> import xml.etree.ElementTree as ET
>>> tree = ET.parse('smp.xml')
>>> root = tree.getroot()
>>>
>>> for text in root.iter('text'):
...     print(text.attrib)
...

Answer 1

这应该让你足够接近:

import pandas as pd
import xml.etree.ElementTree as ET

etree = ET.fromstring(xml_string)

df = pd.DataFrame()

for j in etree.iter('page'):
    for i in  j.iter('text'):        
        dfcols = ['index','text','fontName','fontSize','x','y','width','height','fontStyle']
        df = df.append(pd.Series([j.get('index'),i.text,i.get('fontName'),i.get('fontSize'),i.get('x'),i.get('y'),i.get('width'),i.get('height'),i.get('fontStyle')],index=dfcols), ignore_index=True)

df = df[dfcols]
df.head()

输出:

 index  text          fontName fontSize x       y      width    height  fontStyle
0   1   achene         Arial    12.0    121.10  83.42   71.04   12.00   None
