Example of java regular matching of Chinese characters in a tag in HTML

本文实例讲述了java正则匹配HTML中a标签里的中文字符。分享给大家供大家参考,具体如下:

今天群里一位朋友问到了一个正则表达式的问题,有如下内容:

<a href=&#39;www.baidu.comds=id32434#comment&#39;rewr>特432</a>
453543
<a guhll,,l>a1特123你好123吗?</a>
<a href=id=32434#comment&#39;ewrer>特2</a>
<a>标签中的文字</a>
Copy after login

现在要匹配出内容包含中文但标签的属性中不包含comment的标签中的汉字。

解决思路如下:

1、首先匹配出不包括comment的标签;

2、在匹配结果中进行二次匹配出中文;

代码如下:

输出结果如下:

这里做一下解释:

这个匹配内容包含中文但标签的属性中不包含comment的标签的正则中,不能使用向后查找?<=,因为向后查找只能是固定长度的内容,这里标签中属性不确定,所以不能使用;[\\u4e00-\\u9fa5]+匹配中文字符串;而(?=)使用向前查找?=,在结果中不会包含结束标签。

这个问题就这样得到解决了。如果说要匹配指定标签中的指定内容,那么也是很容易改进的了。若有更好的正则,还请留言相互学习。

希望本文所述对大家java程序设计有所帮助。
