从 Excel 创建动态嵌套 xml

Question

我正在尝试将 Excel 转换为嵌套 XML，但未能按预期成功。

这是我的代码。

import openpyxl
import xml.etree.ElementTree as etree

# reading data from the source, xls
wb1 = openpyxl.load_workbook(filename='C:\GSH\parent_child.xlsx')
ws1 = wb1.get_sheet_by_name('Sheet1')
row_max = ws1.max_row

# creating xml tree structure
root = etree.Element('Hierarchy')

# iterating through the xls and creating children based on the condition
for row_values in range(2, row_max+1):
    parent = etree.SubElement(root, 'parent')
    parent.text = ws1.cell(column=1, row=row_values).value
    root.append(parent)
    if (ws1.cell(column=1, row = row_values).value == ws1.cell(column=2, row = row_values-1).value):
        print("------Inside if condition")
        print(ws1.cell(column=2, row=row_values).value)
        child = etree.SubElement(parent, 'child')
        child.text = ws1.cell(column=2, row=row_values).value
        parent.append(child)
        print("-------Inside if condition")
    tree = etree.ElementTree(root)

tree.write('C:\GSH\gsh.xml')

我得到这样的 XML..

但是，我的 XML 应该是这样的。

任何建议，请。

以上是我正在处理的源 XLS。

您可以设置变量名称而不是父子节点。此代码只是您列表的一部分，看起来很棘手，但工作正常。 d[child[i]].text = " " 只是显示标签的两边。用字典制作var in loop，请参考this。

import xml.etree.ElementTree as ET

India = ET.Element('India')  # set root
parent = ['India', 'Telangana', 'Telangana', 'Telangana','Nalgonda']  # parent list
child = ['Telangana', 'Cyberabad', 'Warangal','Nalgonda','BusStation']  # child list

d = {}  # use dictionary to define var in loop
d['India'] = India

for i in range(len(child)):

    for k, v in d.items():
        if k == parent[i]:
            pa = v
            break

    d[child[i]] = ET.SubElement(pa, child[i])
    d[child[i]].text = " "  # to get both side of tags

tree = ET.ElementTree(India)
tree.write('gsh.xml')

# <India>
# <Telangana>
# <Cyberabad> </Cyberabad>
# <Warangal> </Warangal>
# <Nalgonda>
# <BusStation> </BusStation>
# </Nalgonda>
# </Telangana>
# </India>
