分享如何从网页中提取所需数据？
我已做了一个程序，输入URL地址，能够从该地址中提取HTML中的数据...例如 我输入百度首页 显示如下：连接到站点http://www.baidu.com

XML 解析 用TinyXML库 。 转换为CString 仅限于字符串少的情况下。 用正则表达式。

TinyXML不能直接用來解析HTML,數據不完整.官方明確指出

正则表达式，就是为了处理这类东西的，如果有写过PHP程序，就不会提这种问题了。
Google搜索“正则表达式去除HTML标记”。

可以自己写个字符串筛选，如5楼所说的那样。
还可以用别人封装的正则表达式的类，我这里就有一份

ActiveX空见MSIE自带的函数就可以根据标记提取内容，比如tag <html><body><script>等，获得标记集合然后从中提取内容。
或者可以利用正则表达式
在vc中使用regex的一个简便方法：
1. 生成regex.tlb
1.1 以资源方式打开 c:\windows\system32\vbscript.dll，将第二个typelib导出为 regex.tlb
1.2 vc, tools --> ole/com object viewer，找到 Type Libraraies --> Microsoft VBScript Regular Expression 5.5, 右键 View..，然后在打开的 ITypeLib Viewer 中保存成 regex.idl，再用 midl 工具生成 regex.tlb。这个方法能找到很多其他的 tlb
2. 在vc中导入 regex.tlb
#import "regex.tlb" rename_namespace("RegEx")

那就判断是否是字母，不是字母与数字的，当然就是汉字了。
