Less.html基本使用

背景：做一件代发业务的时候，订单中的产品描述含有大量广告，公司业务需要动态添加/删除指定的数据

参考文档：Less.Html

  • 1.找出描述中含有多个的数据
Dictionary<string, string> keyValues = new Dictionary<string, string>();
foreach (DataRow dataRow in dataRowCollection)
{
    var sp = dataRow["Specification"].ToString();
    var sku = dataRow["ProductId"].ToString();
    Document document = HtmlParser.Parse(sp);
    var q = Selector.Bind(document);
    var trs = q("tr");
    foreach (var tr in trs)
    {
        var tds = q(tr).find("td");
        if (tds.length >= 3)
        {
            keyValues.Add(sku, sp);
            break;
        }
    }
}
  • 2.去掉指定数据
if (!string.IsNullOrEmpty(detail.description))
{
    Document document = HtmlParser.Parse(detail.description);
    var q = HtmlParser.Query(detail.description);

    var ps = q("p");
    foreach (var item in ps)
    {
        if (Regex.IsMatch(item.textContent, @"[\u4e00-\u9fa5]"))
        {
            string s = Regex.Replace(item.textContent, @"[\u4e00-\u9fa5]", "");
            item.textContent = s;
        }
    }

    var spans = q("span");
    foreach (var item in spans)
    {
        if (Regex.IsMatch(item.textContent, @"[\u4e00-\u9fa5]"))
        {
            string s = Regex.Replace(item.textContent, @"[\u4e00-\u9fa5]", "");
            item.textContent = s;
        }
    }

    var fonts = q("font");
    foreach (var item in fonts)
    {
        if (Regex.IsMatch(item.textContent, @"[\u4e00-\u9fa5]"))
        {
            string s = Regex.Replace(item.textContent, @"[\u4e00-\u9fa5]", "");
            item.textContent = s;
        }
        if (item.textContent.Contains("微信号"))
        {
            item.textContent = item.textContent.Replace("微信号", "");
        }
        if (item.textContent.ToLower().Contains("wechat"))
        {
            item.textContent = item.textContent.Replace("WeChat", "");
            item.textContent = item.textContent.Replace("wechat", "");
        }
        if (item.textContent.ToLower().Contains("qq"))
        {
            item.textContent = item.textContent.Replace("qq", "");
            item.textContent = item.textContent.Replace("QQ", "");
        }
    }

    var imgs = q("img");
    foreach (var item in imgs)
    {
        var src = item.getAttribute("src");
        if (src.Contains("data:image"))
        {
            item.setAttribute("src", "");
        }
        if (src.Contains("btbimage"))
        {
            item.setAttribute("src", "");
        }
        if (src.Contains("https://timgsa.baidu.com/"))
        {
            item.setAttribute("src", "");
        }
    }
    detail.description = document.ToString();
}
