此數據：

enter image description here

到目前爲止，我有這樣的：

foreach (var row in htmlSnippet.DocumentNode.SelectNodes("//table[@class = 'style_15']/tbody/tr")) 
       { 
        foreach (var cell in row.SelectNodes("div[@class='*']")) 
        { 
         textBox1.Text = cell.InnerHtml.ToString(); 
        } 
       }

但是我沒有回報任何東西！

這條線的工作：

//table[@class = 'style_15']/tbody/tr

但這並不返回參選：

("div[@class='*']"))

請讓我知道我做錯了！我需要幫助的每一塊數據的返回，如下圖所示的（除了字段名）

您似乎已經跳過TD ... row.SelectNodes（「TD/DIV [@class = '*']」） – 2012-02-13 19:21:38

@amit_g感謝你的幫助，沒有工作 – 2012-02-13 19:26:20

@patrick IM對不起這些工作。它通過外表循環與//表... ....但永遠不會進入內循環 – 2012-02-13 19:32:37

你可能想簡單地div[@class] —具有class屬性的div元素。

噢，值得注意的是，您提供的HTML/XML示例是不是格式良好的。我不得不刪除所有col元素，並關閉br元素。也許，對於C＃來說，這是一個問題......我知道這是針對XSL的......一般來說......不確定XPath。

我沒有時間編寫了一個C＃示例，但這裏有一個簡單的XSL：

<xsl:template match="/"> 
    <so> 
    <xsl:apply-templates select="//table[@class = 'style_15']/tbody/tr"/> 
    </so> 
</xsl:template> 
<xsl:template match="div[@class]"> 
    <xsl:copy-of select="."/> 
</xsl:template>

我得到這樣的輸出：

<so> 
    <div class="style_18">1/30/12</div> 
    <div class="style_19">ZZ324sdf</div> 
    <div class="style_18">51446/75</div> 
    <div class="style_20">HOLD_DE</div> 
    <div class="style_20">234234</div> 
    <div class="style_20">smith, john</div> 
    <div class="style_20">PPPM-6P - SOME AGENCY</div> 
    <div class="style_18">1/31/12</div> 
    <div class="style_19">SFD3434</div> 
    <div class="style_18">51668/17</div> 
    <div class="style_20">HOLD_DE</div> 
    <div class="style_20">FOY, EL</div> 
    <div class="style_20">FOY, ALEX</div> 
    <div class="style_20">someagency &amp; Associates LLC</div> 
    <div class="style_18">1/31/12</div> 
    <div class="style_19">SFD3434</div> 
    <div class="style_18">51668/25</div> 
    <div class="style_20">HOLD_DE</div> 
    <div class="style_20">JAMISON, PA</div> 
    <div class="style_20">JAMISON, ROY</div> 
    <div class="style_20">someagency &amp; Associates LLC</div> 
    <div class="style_18">1/31/12</div> 
    <div class="style_19">SFD3434</div> 
    <div class="style_18">51669/34</div> 
    <div class="style_20">HOLD_DE</div> 
    <div class="style_20">NEWMAN, SO</div> 
    <div class="style_20">NEWMAN, ALEX</div> 
    <div class="style_20">someagency &amp; Associates LLC</div> 
</so>

這只是一箇中間輸出顯示XPath工作正常。

希望這會有所幫助。

這就是非常感謝這麼多〜!!!!!!! – 2012-02-13 19:37:24

的*通常用於任何元件匹配或屬性名稱，又沒值。如果要將所有具有class屬性的div元素與任何值匹配，請使用@class。

foreach (var row in htmlSnippet.DocumentNode.SelectNodes("//table[@class = 'style_15']/tbody/tr/td")) 
{ 
    foreach (var cell in row.SelectNodes("div[@class]")) 
    { 
     textBox1.Text = cell.InnerHtml.ToString(); 
    } 
}
