在字符串中查找多个项目

Question

我正在解析一堆员工事故报告以用于报告目的.

事件报告本身是自由文本,我必须按身体位置对伤害进行分类.我想避免if{}elseif{}elseif{}....}else{}.

事件报告示例:

Employee slipped on wet stairs and injured her knee and right arm, and struck her head on the handrail.

应该在受影响的区域添加"膝盖","手臂"和"头部".

Employee was lifting boxes without approved protective equipment resulting in a back strain.

应该向受影响的区域添加"返回".

While attempting to unjam copier, employee got right index finger caught in machinery resulting in a 1-inch cut.

应该在受影响的区域添加"手指".

现在,我有:

private static StaffInjuryData setAffectedAreas(String incident, StaffInjuryData sid){
   incident = incident.toUpperCase(); //eliminate case issues

   if(incident.contains("HEAD")){
       sid.addAffectedArea("HEAD");
   }else if(incident.contains("FACE")){
       sid.addAffectedArea("FACE");
   }else if(incident.contains("EYE")){
       sid.addAffectedArea("EYE");
   }else if(incident.contains("NOSE")){
       sid.addAffectedArea("NOSE");
   }
   //etc, etc, etc
   return sid;
}

是否有更简单/更有效的方法if-elseif-ad inifinitum来做到这一点？

一种方法是从各个身体部位构造正则表达式,使用它来搜索字符串,并将单个匹配添加到列表中:

Pattern bodyParts = Pattern.compile("\\b(head|face|eye|nose)\\b", Pattern.CASE_INSENSITIVE);

使用的\b两端防止部分匹配,例如发现"head"在包含文本"forehead"或"eye"内部的"eyelid".
