java 正则匹配第一个结果,其余丢弃?????

Question

这是java的正则: Pattern pattern01=Pattern.compile("(dataIndex.*:((\'(.*?)\')||(\"(.*?)\"))[,]?)");
        Matcher matcher01=pattern01.matcher(line);        if(matcher01.find()){
         System.out.println(matcher01.group());
        }以下是匹配的结果:dataIndex:"name",id:"name",locked:
dataIndex:"sex",id:"sex",renderer:sexChange,locked:
dataIndex:"age",id:"age",sortable:true,renderer:ageChange,locked:
dataIndex:"patient_no",id:"patient_no",locked:
dataIndex:"cardid",id:"cardid",locked:
dataIndex:"coopmedcode",id:"coopmedcode",locked:
dataIndex:"freetype_name",id:
dataIndex:"casehistory_no",id:
dataIndex:"in_order",id:"in_order",align:
dataIndex:"birthday",id:"birthday",align:"center",renderer:
dataIndex:"marragename",id:"marragename",align:
dataIndex:"jobname",id:"jobname",align:
dataIndex:'nation'
dataIndex:'nativename'
dataIndex:'id_card'
dataIndex:'address2'
dataIndex:'in_day_date',renderer:
dataIndex:'out_day_date',align:'center',renderer:

dataIndex:'out_ward_code'
dataIndex:'change_office_code'
dataIndex:'mz_icd10name'
dataIndex:'style_in',renderer:

dataIndex:'mostly_ccd_bz'
dataIndex:'mostly_ccd_zh'
dataIndex:'out_status_chinese',renderer:
dataIndex:'out_flag',renderer:
dataIndex:'payowe_fee'想要的结果:
dataIndex:"name",id:"name",locked: 例如这个变成这样dataIndex:"name",
dataIndex:"jobname",id:"jobname",align:例如这个变成这样dataIndex:"jobname",
以下的都是满足的.

已经搞定 Pattern pattern01=Pattern.compile("dataIndex:((\"(.*?)\")|(\'(.*?)\'))[,]?");
        Matcher matcher01=pattern01.matcher(line);
是或者写错了不是||是|大家也要注意了哦

Answer 2

没必要这么复杂吧？你试试这个，直接给你搞定：
        String line = "dataIndex:\"sex\",id:\"sex\",renderer:sexChange,locked:";
        System.out.println(line.replaceAll("([^,]*)[^$]*", "$1"));输出：
  dataIndex:"sex"

Answer 3

如果.*代表贪婪匹配的模式 需要改为勉强 Pattern pattern=Pattern.compile("header.*?:((\"(.*?)\")|(\'(.*?)\'))[,]?");就会得到上面我的问题想要的结果

Answer 4

如果想要得到我上面的答案:
请注意在你的正则中出现了.*那么就是贪婪匹配模式,改为勉强.*? Pattern pattern=Pattern.compile("dataIndex.*?:((\"(.*?)\")|(\'(.*?)\'))[,]?");这样就可以完成我想要的功能,由于我在做Excel导出而有时候列多达上百,而这些列来源是Extjs中的列表头
所以才写正则去匹配的,方便而又不容易出错!
