我正在尝试从一个正式的页面中提取一个链接,我似乎无法通过简单的谷歌搜索找到...这可能很简单,但 xpath 不是我的专业领域
我正在使用 c# 并尝试提取链接并将其写入控制台以弄清楚如何获取链接
这是我的 C# 代码
var document = webGet.Load("http://classifieds.castanet.net/cat/vehicles/cars/0_-_4_years_old/");
var browser = document.DocumentNode.SelectSingleNode("//a[starts-with(@href,'/details/')]");
if (browser != null)
{
string htmlbody = browser.OuterHtml;
Console.WriteLine(htmlbody);
}
html代码部分是
<div class="last">…</div><a href="/cat/vehicles/cars/0_-_4_years_old/?p=13">13</a><a href="/cat/vehicles/cars/0_-_4_years_old/?p=2">»</a>
<select name="sortby" class="sortby" onchange="doSort(this);">
<option value="">Most Recent</option>
<option value="of" >Oldest First</option>
<option value="mw" >Most Views</option>
<option value="lw" >Fewest Views</option>
<option value="lp" >Lowest Price</option>
<option value="hp" >Highest Price</option>
</select><div style="clear:both"></div>
</div>
