一、方法说明
通过IDomObject元素，获取完整的CSS选择器，过滤HTML和BODY元素，自动将class、id添加到选择器上，优先添加class，无class再添加id。如:
<html> <head></head> <body> <div id="result"> <h3 class="t"><a "="" href="http://www.baidu.com/link?url=PgEyrxusTKZjg64DFOd_qlTy4o7dXLH_26WOy1mg6JUwVE4L_KrH24eG7s49yN8R-iBqQEb80m2gLmAzab8FIK&ck=4276.4.1526360648567.0.0.250.568.0&shh=www.baidu.com&sht=baidu" target="_blank">CSS教程</a></h3> </div> </body> </html>
a元素的完整的CSS选择器为：DIV#result H3.t A
二、方法实现
public string GetFullCssSelector(IDomObject dom)
{
string str = "";
while (dom != null && dom.NodeName != null)
{
string nodeName = dom.NodeName;
if (!(new[] {"HTML", "BODY"}.Contains(nodeName))) //过滤HTML、BODY
{
if (dom.HasAttribute("class"))
{
string s = dom.Attributes["class"];
s = s.Replace(" ", " ").Replace(" ", " ").Replace(" ", " ");
string[] strings = s.Split(‘ ‘);
foreach (string str2 in strings)
{
nodeName += "." + str2;
}
}
else if (dom.HasAttribute("id"))
{
nodeName += "#" + dom.Attributes["id"];
}
str = nodeName + " " + str;
}
dom = dom.ParentNode;
}
return str.Trim();
}
