Answer 5

StringBuilder sb=new StringBuilder();
Regex.Matches("你的html源文件", @"(?is)(?<=\>)[^<(]+?(?=\()").OfType<Match>().Select(x => x.Value).ToList().ForEach(x =>
            {
                sb.Append(x + "\n");
            });
Console.Write(sb.ToString());

Answer 6

这样会报错的啊，你是asp.net 吗？

Answer 7

你用控制台程序试下就知道了asp.net的一样，不用Console输出就行了

Answer 8

foreach(Match ma in Regex.Matches("你的html源文件", @"(?is)(?<=\>)[^<(]+?(?=\()"))
{
sb.Append(ma.Value);
}

Answer 9

            string str = File.ReadAllText(@"E:\1.txt");
            Regex reg = new Regex(@"(?<=(['""]?))[^()>'""]+(?=\1\([^)]+\))");
            foreach (Match m in reg.Matches(str))
                Console.WriteLine(m.Value);

这是获取页面的数据，就取刚刚你取的那些值

Answer 17

你还是没有说清楚你的规律额...比如<span id="ProductsSearchLayout_DynamicProductGrid1_ProductsDataList_ctl00_ProductImageWrapLabel">
                        <div style="text-align: center;">
                            <a id="ProductsSearchLayout_DynamicProductGrid1_ProductsDataList_ctl00_ProductImageLink" title="CHI Air Expert Tourmaline Ceramic Nylon Round Brush - Small" href="/p-15645-chi-air-expert-tourmaline-ceramic-nylon-round-brush-small.aspx">
<img title="CHI Air Expert Tourmaline Ceramic Nylon Round Brush - Small" src="//skincare-img.skinstore.com/resources/dynamic/store/indeximages/CE016-nylon-round.jpeg" style="border-width:0px;" /></a></div>
                    </span>
//这个span是要获取img的src <span style="float: left">
                        <strong>$14.00</strong>
                        </span>
//这个span是要获取strong中的$14.00<span id="ProductsSearchLayout_DynamicProductGrid1_ProductsDataList_ctl00_ProductSKULabel"
class="subNav">&nbsp;&nbsp;<font color="black">|</font>&nbsp;&nbsp;CE016</span>
//这个span要获取CE016<span id="ProductsSearchLayout_DynamicProductGrid1_ProductsDataList_ctl00_ProductStockStatu
sLabel" class="stockStatus">In Stock</span></span>//这个span要获取in Stock这些有什么规律？

Answer 18

你帮我看看这样能用正则式获取吗？不行，就帮我写个获取这个span标签里面的内容就好了，还是循环的哦，谢谢了

Answer 19

可以是可以，不过要通过多步验证匹配或替换
如果硬写成一句的话处理的分支条件以及回朔很多，效率很低。
你可以先获取每个span中的内容。
然后在判断是否有img 有的话取src
判断是否有strong 有的话取strong里的内容
判断有没有不需要的标签，例如上面的font标签
&nbsp;&nbsp;<font color="black">|</font>&nbsp;&nbsp;CE016
有的话替换为空。
还是得要有规律
要自己总结出来。

Answer 20

你帮我写个获取这个span所有的数据，我在用程序来截取吧，我闲程序写太麻烦了，才想用正则式
谢谢了哦
