你好，请问这个程序还可以使用吗？
如：
<div class="positionInfo"><span class="positionIcon"></span><a href="https://gz.lianjia.com/xiaoqu/2110343238336681/" target="_blank" data-log_index="1" data-el="region">华南新城 </a> - <a href="https://gz.lianjia.com/ershoufang/huananxincheng/" target="_blank">番禺区</a> </div>
原代码：
elif tag == "a" and ("data-el", "region") in attrs:
self.flag.append("villageName")
怎样把后面的 target="_blank" 加上呢。
我新手，可否赐教
