我想像这样替换每场比赛:
fn.doc(
fn.collection(
fn.distinctValues( # convert to camelcase also
我可以使用正则表达式找到匹配但不知道如何进行替换
这是正则表达式(\w+)(:)(\w+-\w+\()|(\w+)(:)(\w+\()
http://regex101.com/r/kD9zG8
预期输出:
let $local-config := fn.doc($alert-action)/alert:action/alert:name
let $local-coll := fn.collection($uri)/alert:action/alert:name
let $global-coll := fn.distinctValues(fn.collection($global-uri)/alert:action/alert:name[../alert:name = 'ml_alert_action_17_01_action'])
请帮忙!

以下简单的正则表达式应该有效:
use strict;
use warnings;
my $data = do {local $/; <DATA>};
$data =~ s/(\w+):(\w+)-?(\w*)\(/$1.$2\u$3(/g;
print $data;
__DATA__
let $local-config := fn:doc($alert-action)/alert:action/alert:name
let $local-coll := fn:collection($uri)/alert:action/alert:name
let $global-coll := fn:distinct-values(fn:collection($global-uri)/alert:action/alert:name[../alert:name = 'ml_alert_action_17_01_action'])
输出:
let $local-config := fn.doc($alert-action)/alert:action/alert:name
let $local-coll := fn.collection($uri)/alert:action/alert:name
let $global-coll := fn.distinctValues(fn.collection($global-uri)/alert:action/alert:name[../alert:name = 'ml_alert_action_17_01_action'])
要处理2个以上的单词,您可以将正则表达式更改为以下内容:
$data =~ s{(\w+):([\w-]+)(?=\()}{"$1.".lcfirst join '', map ucfirst, split /-/, $2}eg;
或者,如果您的perl版本支持/r
开关:
$data =~ s{(\w+):([\w-]+)(?=\()}{"$1.".$2=~s/-(.)/\u$1/gr}eg;
