我有一套庞大的html代码,有图像的 lo,问题在于,每一个图像都有不同的道路,例如:
<img src=”。
<img src=”。
我想经常表达的是,找到每一个图像途径,代之以:
<img src=”。
我知道,这显然有可能以定期表达......但是,这只是我对茶叶的up子,难道能帮助我吗?
Cheers, Mart

这可能不是最佳解决办法,但可以发挥作用:
(<img.*?src=")([^"]*?(/[^/]*.[^"]+))
接着,你利用第1组和第3组来制造新的扼杀(取决于lav夫):
$1../img$3

如果你想要教导html,如果你使用html的教区而不是reg子,则会更好。 他们中有相当一部分,他们的工作非常好。
