我有几条字符串:
Central and Western</td><td><a href="javascript:pop1('major-housing-estate/30006.html');" title="Kwun Lung Lau">Kwun Lung Lau
Central and Western</td><td><a href="javascript:pop1('major-housing-estate/61782.html');" title="The Merton">The Merton
Eastern</td><td><a href="javascript:pop1('major-housing-estate/10038.html');" title="Fung Wah Estate">Fung Wah Estate
Wong Tai Sin</td><td><a href="javascript:pop1('major-housing-estate/20134.html');" title="Tsz Oi Court">Tsz Oi Court
我想删除并替换中间部分:
从:
</td><td><a href="javascript:
到:
">
我想用以下字符替换整个部分:
;
我需要我的琴弦变成:
Central and Western;Kwun Lung Lau
Central and Western;The Merton
Eastern;Fung Wah Estate
Wong Tai Sin;Tsz Oi Court
我如何以通用方式做到这一点?
