java 正则表达式

我猜你要的其实是JAVACRIPT,而不是JAVA,所以两个都给你.

javascript:

result 是存到这个变量
SUBJECT是原字串
result = subject.replace(/<br>(.*?)<\/br>/g, "$1");

JAVA:

try {
String resultString = subjectString.replaceAll("<br>(.*?)</br>", "$1");
} catch (PatternSyntaxException ex) {
// Syntax error in the regular expression
} catch (IllegalArgumentException ex) {
// Syntax error in the replacement text (unescaped $ signs?)
} catch (IndexOutOfBoundsException ex) {
// Non-existent backreference used the replacement text
}
