blocks|key|2628769|text|封闭列中的第一个单元格的XPath是//div[@id='prices']/table/tbody/tr[2]/td[5]，第二个单元格是//div[@id='prices']/table/tbody/tr[3]/td[5]，依此类推。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2628770|entityMap^0|I|17|1X|17|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

XPath for the first cell in Close column is <code>//div[@id='prices']/table/tbody/tr[2]/td[5]</code> and for the second one it's <code>//div[@id='prices']/table/tbody/tr[3]/td[5]</code> and so on.

blocks|key|2269663|text|做这件事有很多方法。这里有一个解决方案，它基于数据td+(使用'lm‘类的解决方案)：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2269664|HtmlAgilityPack.HtmlDocument+doc+=+new+HtmlAgilityPack.HtmlDocument();
...+load+the+doc+...

foreach+(HtmlNode+node+in+doc.DocumentNode.SelectNodes("//td[@class='lm']/../td[5]"))
{
++++Console.WriteLine("node="+%2B+node.InnerText);
}|code-block|syntax|javascript|2269665|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

There are many ways to do it. Here is one solution, which is based on the Data td (the one withe the 'lm' class):

<pre><code>HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
... load the doc ...

foreach (HtmlNode node in doc.DocumentNode.SelectNodes("//td[@class='lm']/../td[5]"))
{
 Console.WriteLine("node=" + node.InnerText);
}
</code></pre>

If you're using Firebug or any Firefox extension (like XPather) to obtain the <code>XPath</code> of the elements you need to parse, you might need to remove the <code>tbody</code> tags from the XPath. 

Take a look at the following answer here on SO: <a href="https://stackoverflow.com/questions/1678494/why-does-firebug-add-tbody-to-table">Why does firebug add &lt;tbody&gt; to &lt;table&gt;?</a>

If you're using HtmlAgilityPack, the <code>XPath</code> returned by Firebug or by any other tool related with Firefox may differ, because the HTML source you're parsing can be different from the HTML source in Firefox.

Sometimes might be useful to open the same page in Internet Explorer 8 and using Developer Tools (F12) do the same you're doing with Firebug, or if not, use another tool like HAP Explorer that can be downloaded from the <a href="http://htmlagilitypack.codeplex.com" rel="nofollow noreferrer">HtmlAgilityPack page</a>

I am trying to parse the table from the URL (Google finance) below

<pre><code>http://www.google.com/finance/historical?q=BOM:533278
</code></pre>

I am trying to extract only the close values in the close column. But when i try with the XPATH 

<pre><code>hd.DocumentNode.SelectSingleNode("//td[@class='rgt']")
</code></pre>

I am getting all the nodes of having attribute as class and value of attribute as rgt in one Node.innerText itself.

I need the values one by one, not all at the same time. I must be doing something silly here. Thank you.

Actual XPath found using Firebug is a follows

<pre><code>/html/body/div/div/div[3]/div[2]/div/div[2]
 /div[2]/div/form/div[2]/table/tbody/tr[2]/td[5]
</code></pre>

But some how after the form tag...HTMLagility pack is returning null node. Never thought this would take so long to implement.
