1, 匹配所有标签

regex:
\<.[^<>]*\>

source:
<external_network_location_id>20130401_TXNONC100FFS3101TAUSNPN1733590048828A_0048828</external_network_location_id>

result:
<external_network_location_id>
</external_network_location_id>

2, 匹配指定标签 eg:匹配指定的div标签

regex:
\<\bdiv.*\<\/div\b\>

source:
<div>23dd</div>
<div1>23dd</div1>
<div>23dd33ff</div>

result:
<div>23dd</div>
<div>23dd33ff</div>

3, 匹配某种特定格式的字符串

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
regex:

source:
<li><a href="http://([^\s]+)".+?span.+?\[(.+?)\].+?>(.+?)<

source:
<li><a href="http://www.wea.com/blog/a.html" title="怎样在百度空间添加友情链接"><span class="article-date">[2014/11/13]</span>怎样在百链接</a></li>
<li><a href="http://www.a.com/blog/b.html2" title="怎样在百度空间添加友情链接2"><span class="article-date">[2014/11/12]</span>怎样在百度链接2</a></li>

result:

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

regex:
<external_network_location_id>(.*?)</external_network_location_id>

source:
<external_network_location_id>20130401_TXNONC100FFS3101TAUSNPN1733590048828A_0048828</external_network_location_id>
<external_network_location_id>abcd1234004488877</external_network_location_id>

result:
20130401_TXNONC100FFS3101TAUSNPN1733590048828A_0048828
abcd1234004488877

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
regex:
(?is)<img\s*((?<key>[^=]+)="(?<value>[^"]+)")+?\s*/?>

source:
<img src="acbdd"/><img src="33ff"/><img src="gggggeeee"/><a>33333</a>

result:
key=src value=acbdd
key=src value=33ff
key=src value=gggggeeee

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

regex 1:
(?is)<img\s*((?<key>[^=]+)=(["'])(?<value>[^'"]+)\2)+?\s*/?>([^<>]*?</img>)?
regex 2:
(?is)<img\s+((?<key>[^=]+)=(["']?)(?<value>[^'"]+)\2\s*)+?\s*/?>([^<>]*?</img>)?

source:
<img src="acbdd"/><img src="33ff"/><img src="gggggeeee"/><img src="bb"></img><a>33333</a>
