在C＃中使用xpath的示例 [英] Example using xpath in C #

问题描述

我有一个代码html：

 <  < span class =code-leadattribute> div     id   =  grid    style   =  margin-right：505px; height：700px; >  
 <   div     class   =  box-content    style   =   width：99％; >  
 <   div     class   =  contenttitle >  
 <   div     class   =  left-hd  >  
 <   / div  >  
 <   div     class   =  right-hd >  $ b $bThôngtinthịtrườnggiờt<   / div  >  
 <   / div  >  
 <   div     class   =  inner >  
 <   div     style   =  margin-left：5px; margin-right：8px; >  
 
 <   style     type   =  text / css >  
。 RadGrid_Office2007 .rgHoveredRow 
 {
 background-color：lightyellow！important; 
 background-image：none！important; 
} 
 
 .RadGrid_Office2007 
 {
 border-radius：10px 10px 10px 10px; 
} 
 .headerLeft 
 {
 border-top-left-radius：10px！important; 
} 
 .headerRight 
 {
 border-top-right-radius：10px！important; 
} 
 .RadButton_MetroTouch.rbToggleButton.rbTextButton .rbText 
 {
 background-color：transparent; 
 font-size：13px; 
 font-family ：Arial！important; 
 text-align：center; 
 font-style：italic; 
颜色：蓝色; 
} 
 <   / style  >  
 <   div  >  
 <   span     id   =  ctl00_panelContent_ctl01_ucThongTinThiTruong_lblErr  >  <   / span  >  
 <   / div  >  
 <   div  >  
 & lt;   div     id   =  ctl00_panelContent_ctl01_ucThongTinThiTruong_grdTT    class   =  RadGrid RadGrid_Office2007 rgMultiHeader   样式  = 高度：700px;宽度：100％; >  
 
 <   div     class   =  rgHeaderWrapper >  <   div     id   =  ctl00_panelContent_ctl01_ucThongTinThiTruong_grdTT_GridHeader    class   =  rgHeaderDiv   < span class =code-attribute> style   =  padding-right：16px; overflow：hidden;  >  

i在webbrowser上使用HtmlAgilityPack解析数据，现在我想用xpath来获取他们必须做的数据



代码HtmlAgilityPack：

  var  document = webBrowser1.Document; 
  var  documentAsIHtmlDocument3 =（mshtml.IHTMLDocument3）document.DomDocument; 
 
  var  htmlString = documentAsIHtmlDocument3.documentElement.innerHTML; 
 
 HtmlAgilityPack.HtmlDocument doc =  new  HtmlAgilityPack.HtmlDocument（）; 
 doc.LoadHtml（htmlString）; 
 
 
 HtmlNodeCollection texts = doc.DocumentNode.SelectNodes（  // div [ @类= '盒内容'] // DIV [@ ID = 'ctl00_panelContent_ctl01_ucThuyVan_grdGiaTriNuoc_GridData']）; 
  string  kq =  ; 
 
  if （texts！=  null ）
 {
  foreach （ var  item  文本）
 {
 kq + = item.InnerText + Environment.NewLine; 
} 
} 
 richTextBox1.Text = kq; 
 
} 
}

            <div class="box-content" style="width: 99%;">
                <div class="contenttitle">
                    <div class="left-hd">
                    </div>
                    <div class="right-hd">
                        Thông tin thị trường giờ tới</div>
                </div>
                <div class="inner">
                    <div style="margin-left: 5px; margin-right: 8px;">

<style type="text/css">
    .RadGrid_Office2007 .rgHoveredRow
    {
        background-color: lightyellow !important;
        background-image: none !important;
    }

    .RadGrid_Office2007
    {
        border-radius: 10px 10px 10px 10px;
    }
    .headerLeft
    {
        border-top-left-radius: 10px !important;
    }
    .headerRight
    {
        border-top-right-radius: 10px !important;
    }
    .RadButton_MetroTouch.rbToggleButton.rbTextButton .rbText
    {
        background-color: transparent;
        font-size: 13px;
        font-family: Arial !important;
        text-align: center;
        font-style: italic;
        color: Blue;
    }
</style>
<div>
    <span id="ctl00_panelContent_ctl01_ucThongTinThiTruong_lblErr"></span>
</div>
<div>
    <div id="ctl00_panelContent_ctl01_ucThongTinThiTruong_grdTT" class="RadGrid RadGrid_Office2007 rgMultiHeader" style="height:700px;width:100%;">

        <div class="rgHeaderWrapper"><div id="ctl00_panelContent_ctl01_ucThongTinThiTruong_grdTT_GridHeader" class="rgHeaderDiv" style="padding-right:16px;overflow:hidden;">

i have using HtmlAgilityPack parse data on webbrowser, Now I want to use xpath to get the data they must do how

code HtmlAgilityPack:

        var document = webBrowser1.Document;
        var documentAsIHtmlDocument3 = (mshtml.IHTMLDocument3)document.DomDocument;

        var htmlString = documentAsIHtmlDocument3.documentElement.innerHTML;

        HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
        doc.LoadHtml(htmlString);


        HtmlNodeCollection texts = doc.DocumentNode.SelectNodes("//div[@class='box-content']//div[@id='ctl00_panelContent_ctl01_ucThuyVan_grdGiaTriNuoc_GridData']");
        string kq = "";

        if (texts != null)
        {
            foreach (var item in texts)
            {
                kq += item.InnerText + Environment.NewLine;
            }
        }
        richTextBox1.Text = kq;

    }
}
