從文本文件中刪除以 Python 中的特定表達式開頭的單詞

Question

我有一個 XML 文件並將一些特定信息提取到一個新的 txt 文件中。 一切正常，除了在我的新文本文件中有一些我想刪除的單詞。 所有這些詞都以“iVB”開頭，並有不同的結尾。

我的代碼如下：

import xml.etree.ElementTree as ET
tree=ET.parse(r"C:\Users\benni\Google Drive\MASTER\Masterarbeit\Coden\Description.xml")

with open(r"C:\Users\benni\Google Drive\MASTER\Masterarbeit\Coden\Activity.txt", "w")as f:

    for instance in tree.findall(".//ATTRIBUTE"):
        if instance.get("type")== "LONGSTRING":
            f.write(f"{instance.text}\n")

s=open(r"C:\Users\benni\Google Drive\MASTER\Masterarbeit\Coden\Activity.txt").read()
s=s.replace(";", "\n").lower()
f=open(r"C:\Users\benni\Google Drive\MASTER\Masterarbeit\Coden\Activity1.txt", "w")
f.write(s)
f.close() 

我知道我可以使用正則表達式和xx= re.sub(r'\biVB\d*\b', '', x)但是我真的不知道如何將它放入 txt.file

我的 XML 文件看起來像這樣。

Answer 1

嘗試這個：

with open(r"C:\Users\benni\Google Drive\MASTER\Masterarbeit\Coden\Activity.txt", "r") as f:
    lines = f.readlines()

with open(r"C:\Users\benni\Google Drive\MASTER\Masterarbeit\Coden\Activity.txt", "w") as f:
    for line in lines:
        if line.strip("\n").startswith("iVB") is False:
            f.write(line)

也許這可以幫助你。 祝你好運！
