Question

继我今天早些时候提出的一个问题之后，我现在让我的状态扫描正则表达式完全符合我的要求。我现在想把状态代码引入我的正则表达式。我的状态名称我想要不区分大小写，我的州代码区分大小写。因此，我在我的正则表达式中放置了两个具有不同大小写设置的模式分组。

当在regex中单独使用时，两个组都按预期工作，但是当我尝试使用两个分组时，只有第二个用于状态名称才能找到匹配项。代码如下：

options noquotelenmax;

data countries;
do i = 1 to 20;
output;
end;
run;

data countries;
length state $50.;
set countries;

if i = 1 then state = 'CALIFORNIA';
if i = 2 then state = 'alabama';
if i = 3 then state = 'NewYork';
if i = 4 then state = 'OHIO';
if i = 5 then state = 'ohio';
if i = 6 then state = 'FLORIDA';
if i = 7 then state = 'georgia';
if i = 8 then state = 'TEXAS';
if i = 9 then state = 'Kansas';
if i = 10 then state = 'MAINE';

if i = 11 then state = 'AL';
if i = 12 then state = 'AK';
if i = 13 then state = 'CO';
if i = 14 then state = 'MT';
if i = 15 then state = 'OH';
if i = 16 then state = 'SD';
if i = 17 then state = 'PA';
if i = 18 then state = 'IA';
if i = 19 then state = 'PW';
if i = 20 then state = 'AP';

run;

data countries;
set countries;
prx_1 = (prxparse(
"/^(?:AL|AK|AZ|AR|

prx_valid_addr_1 = (prxmatch(prx_1, strip(state))) ;
run;

options quotelenmax;

谁能看到我做错了什么？

你有额外的＆＃34; |＆＃34;之后＆＃34; TT＆＃34;没有＆＃34; |＆＃34;两组之间。以下应该有效：

data countries;
set countries;
prx_1 = (prxparse(
"/^(?:AL|AK|AZ|AR|

两个模式分组与PRXPARSE正则表达式？
