regex - 正则表达式和字符串操作

Question

我有以下格式的字符串
blah blah [user:1] ho ho [user:2] he he he
我希望它被替换
blah blah <a href='1'>someFunctionCall(1)</a> ho ho <a href='2'>someFunctionCall(2)</a> he he he
所以有两件事替换了 [user:id] 和一个 methodCall

注意:我想在 groovy 中做到这一点，这样做的有效方法是什么

Answer 1

Groovy，宝贝:

def someFunctionCall = { "someFunctionCall(${it})" }
assert "blah blah [user:1] ho ho [user:2] he he he"
    .replaceAll(/\[user:(\d+)]/){ all, id ->
    "<a href=\"${id}\">${someFunctionCall(id)}</a>"
    } == "blah blah <a href=\"1\">someFunctionCall(1)</a> ho ho <a href=\"2\">someFunctionCall(2)</a> he he he"
