CString获取数字，用正则最好,该如何处理

CString获取数字，用正则最好
CString现在获取html的一个table  如下：  我想提取里面的数据，6.9785  6.9785， 0.1178,0.1178  怎么提取，正则怎么写
<TABLE ALIGN=LEFT>

------解决思路----------------------
假设工程字符集为Unicode，示例代码为：

#include <regex>

#include <string>

#include <vector>

using namespace std;


vector<CString> GetDataFromHtml(const wchar_t *html)

{

	wregex pattern(L"<SPAN ID='A\\d+'>([\\d\\.]+?)\\s*?</SPAN>");

	vector<CString> results;

	wsmatch match;

	wstring html_data = html;

	while (regex_search(html_data, match, pattern))

	{

		results.push_back(match[1].str().c_str());

		html_data = match.suffix();

	}

	return results;

}

需要在VS2010或以上的编译器中编译，否则请使用boost的regex
------解决思路----------------------
把保存着html的CString对象作为参数调用GetDataFromHtml，返回值是一个字符串数组，保存着所有的结果
