Java ReplaceAll在这里没有帮助我

Question

I have a String here,

String message = "hi test message >< abcd < pqr <variable> xyz <tag> testing <>";

I want to replace all <> <tag> <anything> with (.*) as i am trying to build a regex out of it.

I tried the following,

message = message.replaceAll("<(.*)>", "(.*)");

but the result is

hi test message >(.*)

the result i am expecting is this

hi test message >< abcd < pqr (.*) xyz (.*) testing (.*)

Can anyone help me to acheive this result?

ThankYou in advance!

Answer 1

To catch tag contents, try this regexp (assuming they're never nested):

<([^<>])*>

Note that this will completely ignore this part of your test string:

< abcd < pqr

Answer 2

使用以下正则表达式删除所有类型的标签。

@"(?></?\w+)(?>(?:[^>'""]+|'[^']*'|""[^""]*"")*)|(?>(?:[>'""]+|'[^']*'|""[^""]*"")*)"

Answer 3

Provided you really mean to only replace <> , <tag> , <anything> and nothing else, try:

<(tag|anything)?>

If you want to match all enclosed tags, including empty ones:

<[^<>]*>

Answer 4

您可以使用此正则表达式

"<(|tag|anything)>"
