C#正则表达式获取下拉菜单(select)的相关属性值

给几个在c#中，使用正则表达式取页面下拉菜单(select)中的值示例:

//取html中全部 select 的 name
regex reg_name = new regex(@"(?<=<select name=\"").*?(?=\"")");

//取html中全部<select>项的值
regex reg_select = new regex("(?is)<select name=*.*?>]*.*?</select>");

//取html中一个 select name 等于"status"的值
regex status = new regex(@"(?is)<select name=\""status\"">]*.*?</select>");

 

一下是一段完整的代码和方法，取html中一个下拉菜单 select name 等于”status”的中值，添加到dropdownlist中:

string strdoc = （你的html）;

//取html中一个下拉菜单 select name 等于"status"的中值
regex status = new regex(@"(?is)<select name=\""status\"">]*.*?</select>");
matchcollection mc_status = status.matches(strdoc);
getselectoptions(mc_status, cmbstatus);

/// <summary>
/// 取select对列表复制
/// </summary>
/// <param name="selected"></param>
/// <param name="cmb"></param>
void getselectoptions(matchcollection selected, combobox cmb)
{
    if (selected.count < 1)
        return;
    txtvalues.text = "";
    txtvalues.text = selected[0].value.replace("</option>", environment.newline);
    string tmptxt = "";
    foreach (string s in txtvalues.lines)
    {
        if (s == "")
            continue;
        string a = "";
        a = s.replace("\"", "").replace("<option value=\"", "");
        int x = a.lastindexof(">");
        tmptxt += a.substring(x + 1) + environment.newline;
    }
    txtvalues.text = tmptxt.trim();
    cmb.items.clear();
    cmb.items.addrange(txtvalues.lines);
    cmb.selectedindex = 0;
    cmb.size = cmb.preferredsize;
}
