[英]RegEx to match character followed or preceded by another character or both but not neither
[英]Regex until character but if not preceded by another character
我想創建一個正則表達式來匹配一個用Localize("
分割的字符串,並且應該在"
彈出時結束,而不是在"
轉義時結束(前面是\\
)。
我當前的正則表達式沒有考慮到“除非前面有”看起來像:
\bLocalize\(\"(.+?)(?=\")
有任何想法嗎 ?
使用以下字符串:
Localize("/Windows/Actions/DeleteActionWarning=The action you are trying to \"delete\" is referenced in this document.") + " Want to Proceed ?";
我希望它在document.
后停止document.
來了,因為這是第一次"
露面沒有尾隨\\
(這說明周圍delete
)
您可以使用
\bLocalize\("([^"\\]*(?:\\.[^"\\]*)*)
請參閱此正則表達式演示。
詳情:
\\bLocalize
- 一個完整的詞Localize
\\("
- a ("
子串([^"\\\\]*(?:\\\\.[^"\\\\]*)*)
- 捕獲組 1:
[^"\\\\]*
- 除"
和\\
之外的 0 個或多個字符(?:\\\\.[^"\\\\]*)*
- 轉義字符的 0 次或多次重復,后跟除"
和\\
以外的 0 次或更多字符在 Python 中,聲明模式
reg = r'\bLocalize\("([^"\\]*(?:\\.[^"\\]*)*)'
演示:
import re
reg = r'\bLocalize\("([^"\\]*(?:\\.[^"\\]*)*)'
s = "Localize(\"/Windows/Actions/DeleteActionWarning=The action you are trying to \\\"delete\\\" is referenced in this document.\") + \" Want to Proceed ?\";"
m = re.search(reg, s)
if m:
print(m.group(1))
# => /Windows/Actions/DeleteActionWarning=The action you are trying to \"delete\" is referenced in this document.
您可以使用非正則表達式運算符 ^
\\bLocalize(\\".*?[^\\]\\"
