将 XPathNavigator 转换为 HtmlAgilityPack 的 HtmlNode

Question

可以将XPathNavigator 转换为HtmlNode 吗？ 代码如下：

public string ContentByName(string name)
{
    if (name == null)
        throw new ArgumentNullException("name");

    XPathExpression expr = _CreateXPathExpression(String.Format("//meta[@name[Extensions:CaseInsensitiveComparison('{0}')]]", name));
    XPathNodeIterator it = _headNav.Select(expr);
    if (!it.MoveNext())
        return null;

    XPathNavigator node = it.Current;

    // How should I transform XPathNavigator node to HtmlNode here?

}

Answer 1

'it.Current' 在您的示例中返回一个 HtmlNodeNavigator 实例，该实例具有一个 CurrentNode 属性，而该属性又返回 HtmlNode。

例如

HtmlNodeNavigator nodeNavigator = it.Current as HtmlNodeNavigator;
HtmlNode node = nodeNavigator.CurrentNode;
