我需要一个正则表达式，它会贪婪地查找最多150个字符，最后一个字符为'，'。然后用<br />替换150中的最后一个'，' 有什么建议吗？

我使用了这个','(?=[^()]*\))，但是这个替换了所有出现的内容。我希望更换第150个。

感谢大家的建议。我设法使用Java代码而不是正则表达式。

StringBuilder sb = new StringBuilder(html); int i = 0; while ((i = sb.indexOf("','", i + 150)) != -1) { int j = sb.lastIndexOf("','", i + 150); sb.insert(i+1, "<BR>"); } return sb.toString();

然而，这在150个字符中第一次遇到'，'时就会中断。任何人都可以帮助修改我的代码，以便在最后出现'，'时使用150个字符包含中断。

Answer 1

你会想要这样的东西：

查找\([^)]+*,[^)]+*\)的每一个匹配项（查找带有逗号的括号括起的字符串，然后在每个匹配的元素上运行以下正则表达式：

(.{135,150}[^,]*?),

第一个数字是在添加中断标记之前要匹配的最小字符数 - 第二个是最大字符数喜欢在插入break标记之前匹配。如果相关字符之间没有,，则正则表达式将继续使用字符，直到找到逗号。

Answer 2

你可能会这样做：

regex ~ /(^.{1,14}),/
replacement ~ '\1<replacement' or "$1<insert your text>"

Perl：

$target = ','x 22;
$target =~ s/(^ .{1,14}) , /$1<15th comma>/x;
print $target;

Output
,,,,,,,,,,,,,,<15th comma>,,,,,,,

编辑：作为替代方案，如果您想将字符串分解为成功的150或更少你可以这样做：

regex ~ /(.{1,150},)/sg
replacement ~ '\1<br/>' or "$1<br\/>"
// That is a regex of type global (/g) and include newlines (/s)

Perl：

$target = "

    ";

if ($target =~ s/( .{1,150} , )/$1<br\/>/sxg) {
    print $target;
}

输出：

我想用一个字符串替换字符串中第150个位置的'，'
