我看了三天多的正则表达式，但还是不行。上次关于正则表达式的问题，三恨和BOB帮我写了代码，很轻松搞定，现在我想把“天气”，“温度”“风力”“紫外线”提取出来，然后我自己就想写，代码是这样的：
#include <INet.au3>
$oIE=_INetGetSource("http://www.weather.com.cn/html/weather/101010600.shtml")
$sReturn=StringRegExp($oIE,"<(?i)em><strong>(.*?)</(?i)strong>",1);提取出天气代码
msgbos=(64,"test",$sReturn)

用MSGBOX测试的时候，有时候是0，有时候是1，为什么呢？请各路高手帮我写一下！

$sReturn=StringRegExp($oIE,"<(?i)em><strong>(.*?)</(?i)strong>",1);提取出天气代码
msgbox=(64,"test",$sReturn)

不能运行啊!再帮我看看一下啊!

我在顶顶哦！

我对正则表达式也同样的崩溃！:face (1):

pusofalse 发表于 2008-12-30 18:54:35

Dim $var = FileRead("a.txt"), $s

$str = stringRegExp($var, ">([^>]+)<(?:/|br)", 3)
For $d = 0 to Ubound($str) - 1
$s &= $str[$d] & @crLf
Next
msgbox(0, '', $s)

不知道是我测试出问题了还是怎么了，各路高手的代码，我一直测试不通啊·

$oIE=_INetGetSource("http://www.weather.com.cn/html/weather/101010600.shtml")
下载了乱码，先把这问题搞好，你搜索一下论坛吧

abcabc8759 发表于 2009-1-3 09:11:28

OK，已经搞定了乱码，没乱码问题，正则表达式就好了！
