尝试使用Python解析一个XLS (XML)文件。

问题描述 投票：0回答：1

我有一个从Netsuite ERP下载的 "XLS "文件。文件根部写着".XLS"，但它实际上是一个XML文件。我有一个 pandas 脚本，可以将几个 XLS 或 XLSX 文件组合起来，但 pandas 似乎不能处理这种奇怪的 XLSXML 文件类型，所以我有另一个脚本试图解析 XML 数据并保存为 XLS 或 XLSX。然而下面的脚本似乎并不奏效，因为它的结果是 "无"。有谁能给我指出正确的方向，无论是我的示例代码，新的代码，还是新的方法来解决这个奇怪的XLSXML解析问题？

先谢谢你

避免通过附加Series甚至DataFrames等对象来构建数据框架。取而代之的是，建立一个要绑定到字典的列表。DataFrame. 此外，由于你的XML有一个默认的命名空间，你必须指定一个前缀来解析命名空间下的任何元素。

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

ns = {"doc": "urn:schemas-microsoft-com:office:spreadsheet"}

tree = ET.parse(r"C:\Path\To\Input.xml")
root = tree.getroot()

def getvalueofnode(node):
    """ return node text or None """
    return node.text if node is not None else None


def main():
    """ main """
    parsed_xml = tree

    data = []
    for i, node in enumerate(root.findall('.//doc:Row', ns)):
        if i > 6:
            data.append({'account': getvalueofnode(node.find('doc:Cell[1]/doc:Data', ns)),
                         'total': getvalueofnode(node.find('doc:Cell[2]/doc:Data', ns))})

    return(pd.DataFrame(data))

output_df = main()

print(output_df)
#                                    account       total
# 0          10000 - CASH & CASH EQUIVALENTS        None
# 1    10101 - Bank - 9999 - Company A - EUR  1234567.01
# 2  Total - 10000 - CASH & CASH EQUIVALENTS  1234567.01

或者，将你的Excel样式的XML保存为 xlsx 与 Workbook.SaveAs 办法 win32com (仅适用于Windows用户)，并读入与 pandas.read_excel 跳过适当的行。

import win32com.client
import pandas as pd

# SAVE EXCEL FILE
try:
    xlApp = win32com.client.Dispatch("Excel.Application")
    xlWbk = xlApp.Workbooks.Open(r"C:\Path\To\Input.xml")
    xlWbk.SaveAs(r"C:\Path\To\Output.xlsx", 51)

    xlWbk.Close(True)
    xlApp.Quit()

except Exception as e:
    print(e)

finally:
    xlWbk = None; xlApp = None
    del xlWbk; del xlApp

# READ EXCEL FILE
output_df = pd.read_excel(r"C:\Path\To\Output.xlsx", skiprows = 6)

print(output_df)    
#                                    Account       Total
# 0          10000 - CASH & CASH EQUIVALENTS         NaN
# 1    10101 - Bank - 9999 - Company A - EUR  1234567.01
# 2  Total - 10000 - CASH & CASH EQUIVALENTS  1234567.01
