帮忙写一下正则最好解说下

Question

arr[1][3]=['100','xxx','5','img/1.gif'];
arr[1][2]=['100','xxx','3','img/12.gif'];取  1    100   xxx;每列数组对应的取出一行类似数据  

Answer 1

arr[1][3]=['100','xxx','5','img/1.gif'];
arr[1][2]=['100','xxx','3','img/12.gif'];arr\[(?<str>[^\]])]\[\d*\]=\['(?<val1>[^']*)','(?<val2>[^']*)'
测试没问题

Answer 2

(?i)arr\[([^]]+)\][^']+'([^']+)','([^']+)'[^]]+\];分别取Group[1]  Group[2]  Group[3] 的值
