例子：

原始串
str[1]abc[991];
str[2]abc[992];
str[11]abc[993];
str[22]abc[994];
str[111]abc[995];
str[222]abc[996];
str[1111]abc[997];
str[2222]abc[999];

目標(biāo)串：
abc[1];
abc[2];
abc[11];
abc[22];
abc[111];
abc[222];
abc[1111];
abc[2222];

處理：
查找串：str[([0-9]+)]abc[[0-9]+]
替換串：abc[1]

【1】正則表達(dá)式應(yīng)用――替換指定內(nèi)容到行尾
原始文本如下面兩行
abc aaaaa
123 abc 444

希望每次遇到“abc”，則替換“abc”以及其后到行尾的內(nèi)容為“abc efg”
即上面的文本最終替換為：
abc efg
123 abc efg

解決：
① 在替換對(duì)話框，查找內(nèi)容里輸入“abc.*”
② 同時(shí)勾選“正則表達(dá)式”復(fù)選框，然后點(diǎn)擊“全部替換”按鈕
其中，符號(hào)的含義如下：
“.” ＝匹配任意字符
“*” ＝匹配0次或更多

注意：其實(shí)就是正則表達(dá)式替換，這里只是把一些曾經(jīng)提出的問題加以整理，單純從正則表達(dá)式本身來(lái)說(shuō)，就可以引申出成千上萬(wàn)種特例。

【2】正則表達(dá)式應(yīng)用――數(shù)字替換
希望把
asdadas123asdasdas456asdasdasd789asdasd
替換為:
asdadas[123]asdasdas[456]asdasdasd[789]asdasd

在替換對(duì)話框里面，勾選“正則表達(dá)式”復(fù)選框；
在查找內(nèi)容里面輸入“[0-9][0-9][0-9]”，不含引號(hào)
“替換為:”里面輸入“[
