如何在正則表達式中考慮特殊的非ASCII字符

Question

我不知道這是否是問題，但我似乎無法得到這個匹配。

String [] seTab3_HighRes=null;

public Map<String, String> tab3HighResRegex(String x, Map<String,String> map) {

Pattern Tab3_HighRes_pattern = Pattern.compile("High Resolution Parameters:(.*?Intrabolus pressure)",Pattern.DOTALL);
Matcher matcherTab3_HighRes_pattern = Tab3_HighRes_pattern.matcher(x);


while (matcherTab3_HighRes_pattern.find()) {
    System.out.println("Anything here? Nope");
    seTab3_HighRes=matcherTab3_HighRes_pattern.group(1).split("\\n|\\r");
    }
}

案文是：

 High Resolution Parameters:
    Intrabolus pressure (@LESR)(mmHg):-3.7 <8.4
    Some other stff: 123
    Intrabolus pressure (avg max)(mmHg):8.3 <17.0

我在文本中看了一下，注意到High Resolution Parameters:末尾有一個^G字符High Resolution Parameters:當我將文本粘貼到textpad中時。 它是什么，是因為我沒有得到匹配（以及如何擺脫它？

描述

你可以簡單地將^G控制G與\\cG ，

這個正則表達式執行以下操作：

• 匹配High Resolution Parameters:
• 找到第一個Intrabolus pressure
• 在Intrabolus pressure ... :后拉出子串Intrabolus pressure ... :

正則表達式

High\sResolution\sParameters:(?:\cG|[\n\r\s])*(?:Intrabolus\spressure)[^:]*:([^\n]*)

說明

• Capture Group 0獲取整個字符串
• Capture Group 1獲得Intrabolus pressure值
