自定義分割操作

Question

我覺得有幾個XPath表達式，如：

loan:_applicant/base:_entity/person:_locations/base:SmartRefOfLocationeJDvviUx[base:_entity/contact:_category/base:_underlyingValue='Personal' and base:_entity/contact:_confirmedByResident/common:_isConfirmed/base:_underlyingValue='true' and base:_entity/base:_process/base:_entity/base:_id/base:_underlyingValue = /loan:Application/base:_process/base:_entity/base:_id/base:_underlyingValue]/base:_entity/base:_id/base:_underlyingValue 

我嘗試使用/base:_entity部分這些表達式拆分爲這樣的分配器：

string[] stringSeparators = new string[] { "/base:_entity" }; 
string[] pathTokens = xPath.Split(stringSeparators, StringSplitOptions.None); 

但我需要防止分裂當/base:_entity介於[和]個字符之間時。

我有可能產生以下字符串數組爲我寫了上面的示例表達式輸出是：

"loan:_applicant" 
"/person:_locations/base:SmartRefOfLocationeJDvviUx 
[base:_entity/contact:_category/base:_underlyingValue='Personal' and base:_entity/contact:_confirmedByResident/common:_isConfirmed/base:_underlyingValue='true' and base:_entity/base:_process/base:_entity/base:_id/base:_underlyingValue = /loan:Application/base:_process/base:_entity/base:_id/base:_underlyingValue]" 
"/base:_id/base:_underlyingValue" 

你有什麼建議嗎？

我會使用一些可愛的正則表達式，如(?<=^.*\][^\[]*|^[^\[\]]*)/base:_entity，然後使用Regex的方法Split。它使用積極的後視來檢查左邊的第一個支架是否是右邊的支架']'或根本沒有支架。
