[英]VB.Net - Use regular expression to identify new lines between double quotes
我有以下字符串值:
1A-2A-3A-"Comment line 1
Comment line 2
Comment line A1
Comment line A2"-BREAK1
1B-2B-3B-"Comment line 3
Comment line 4"-BREAK2
1C-2C-3C-4C-BREAK3
1D-2D-3D-4D-BREAK4
我想在vb.net中使用正則表達式,以得到以下結果:
1A-2A-3A-"Comment line 1|Comment line 2|Comment line A1|Comment line A2"-BREAK1
1B-2B-3B-"Comment line 3|Comment line 4"-BREAK2
1C-2C-3C-4C-BREAK3
1D-2D-3D-4D-BREAK4
基本上,規則是刪除雙引號之間的所有新行。
任何幫助都將受到歡迎!
我想出了下一個解決方案:
Dim vInput = <xml>1A-2A-3A-"Comment line 1
Comment line 2
Comment line A1
Comment line A2"-BREAK1
1B-2B-3B-"Comment line 3
Comment line 4"-BREAK2
1C-2C-3C-4C-BREAK3
1D-2D-3D-4D-BREAK4</xml>.Value
Dim vRegExMatch = System.Text.RegularExpressions.Regex.Matches(vInput, """[^""\\]*(?:\\.[^""\\]*)*""|'[^'\\]*(?:\\.[^'\\]*)*'")
Dim vSpecialChar As Char = "|" '"†"
For Each vMatch In vRegExMatch
vInput = vInput.Replace(CStr(vMatch.Value), CStr(vMatch.Value).Replace(vbLf, vSpecialChar))
Next
結果:
1A-2A-3A-"Comment line 1|Comment line 2|Comment line A1|Comment line A2"-BREAK1
1B-2B-3B-"Comment line 3|Comment line 4"-BREAK2
1C-2C-3C-4C-BREAK3
1D-2D-3D-4D-BREAK4
希望對別人有幫助!
