python 正则 多行 非贪婪匹配 (求助)

qimuzhi

请教下:
下文测试代码中, 我多行匹配, 但是匹配到的结果有错误.(用红字标出)
我只想要Total PSS by category:下面几行的内容.

代码复制粘贴可执行.看着长, 因为测试字符串长.

因为有干扰项, 我没办法排除, 请赐教!

我实验出来了:

修改下
def get_pss_by_category(match_str):
    pattern = re.compile(r'Total PSS by category:.*?([0-9,]*)K%s\n' % match_str, re.DOTALL)
    ram_kb = pattern.findall((test_str).replace(",", ""))
    logging.warning("%s: %s" % (match_str, ram_kb))
    return ram_kb

def get_pss_by_category(match_str):
    pattern = re.compile(r'Total PSS by category:.*?([0-9,]*)K%s\n' % match_str, re.DOTALL)
    ram_kb = pattern.findall((test_str).replace(",", ""))
    logging.warning("%s: %s" % (match_str, ram_kb))
    return ram_kb
