HtmlAgilityPack获取#开头节点的XPath

获取文档的XPath,有些文字元素没有包含在节点里面,

比如

 

用HtmlAgilityPack获取的XPath如下:

  /html[1]/body[1]/div[1]/div[2]/div[1]/div[2]/div[1]/div[4]/article[1]/section[1]/div[1]/p[1]/#text[1]

但是用doc.DocumentNode.SelectSingleNode(xpath);获取就会报错;

xpath改成这样就可以了

  /html[1]/body[1]/div[1]/div[2]/div[1]/div[2]/div[1]/div[4]/article[1]/section[1]/div[1]/p[1]/text()[1]

写个方法转换一下:

public static string rexpt(string p)
{
    var resxpath = p;
    if (Regex.IsMatch(p, @"/#[a-z]+(\[\d+\])?$"))
    {
        var end = Regex.Match(p, @"/#[a-z]+(\[\d+\])?$").Value;
        var rep = Regex.Match(end, @"[a-z]+").Value + "()" + Regex.Match(end, @"\[\d+\]").Value;
        resxpath = Regex.Replace(resxpath, @"/#[a-z]+(\[\d+\])?$", "/" + rep);
    }
    return resxpath;
}
