我想从下面的字符串中找到一个模式。所有单词都包含“MATCH.TEXT3”,可能是最新的与结尾数字匹配的。
{MATCH.TEXT1.1=[1, admin, 07/10/14 09:29:34], MATCH.TEXT2.2=[2, admin, 07/10/14 10:01:08], MATCH.TEXT3.3=[3, admin, 07/10/14 10:08:01], MATCH.TEXT3.4=[4, admin, 07/10/14 11:08:01], MATCH=[TEXT3]}
预期产出:
MATCH.TEXT3.4
or
MATCH.TEXT3.3
MATCH.TEXT3.4

您可以对字符串使用findAll()方法来提取与给定模式匹配的标记:
String s = '{MATCH.TEXT1.1=[1, admin, 07/10/14 09:29:34], MATCH.TEXT2.2=[2, admin, 07/10/14 10:01:08], MATCH.TEXT3.3=[3, admin, 07/10/14 10:08:01], MATCH.TEXT3.4=[4, admin, 07/10/14 11:08:01], MATCH=[TEXT3]}'
List<String> tokens = s.findAll(/MATCH\.TEXT3(\.[0-9]+)?/)
assert tokens == ['MATCH.TEXT3.3', 'MATCH.TEXT3.4']
String last = tokens.last()
assert last == 'MATCH.TEXT3.4'

最后一场比赛:
class Finder {
static main(args) {
def str = '''<your string>'''
def textFinder= /(MATCH.TEXT3.\d+)/
def textMatcher = str=~textFinder
if(textMatcher.size()>0){
def lastMatch = (Integer) textMatcher.size() - 1
println (textMatcher=textMatcher[lastMatch][1])
}
}
}
输出:
MATCH.TEXT3.4
所有比赛都很容易改变。
