嘗試使用 Python 解析 XLS (XML) 文件
[英]Attempting to Parse an XLS (XML) File Using Python
問題描述
我有一個從 Netsuite ERP 下載的“XLS”文件。 文件根目錄顯示“.XLS”，但它實際上是一個 XML 文件。 我有一個 pandas 腳本，它將組合幾個 XLS 或 XLSX 文件，但 pandas 似乎無法處理這種奇怪的 XLS/XML 文件類型，所以我有另一個腳本試圖解析 Z3501BB093D363810B67CFED 數據並保存到 XLS 然而，下面的腳本似乎不起作用，因為它導致“無”。 誰能用我的示例代碼、新代碼或解決這個奇怪的 XLS/XML 解析問題的新方法為我指明正確的方向？
先感謝您！

Python 代碼解析 XML 到 XLS：
import pandas as pd
import xml.etree.cElementTree as ET
tree = ET.parse(r"C:\Users\NAME\Documents\rootfolder\examplefile.xls")
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
dfcols = ['account', 'total']
df_xml = pd.DataFrame(columns=dfcols)
for node in parsed_xml.getroot():
account = node.attrib.get('Type="String"')
total = node.find('Type="Number"')
df_xml = df_xml.append(
pd.Series([account, getvalueofnode(total)], index=dfcols),
ignore_index=True)
print(df_xml)
main()
Python 解析 XML 文件結果：

避免通過附加像 Series 甚至 DataFrames 這樣的對象來構建數據框。 相反，構建要綁定到DataFrame的字典列表。 此外，由於您的 XML 具有默認命名空間，因此您必須分配前綴來解析命名空間下的任何元素
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
Alternatively, save your Excel styled XML as xlsx with Workbook.SaveAs method using win32com (only for Windows users) and read in with pandas.read_excel skipping appropriate rows.
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
