Anyone can help me I use Copy Xpath in Google chrome tools developement to get this path :
/html/body/table/tbody/tr/td/table[2]/tbody/tr/td/table[1]/tbody/tr[1]/td[2]/table[2]/tbody/tr[1]/td/div[2]/div[1]/table/tbody/tr/td/table/tbody/tr[2]/td[1]and I use the path in this code to get data :
HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(webBrowser1.Document.GetElementById("tablemasterbleue").InnerHtml);
int i = 2;
while (doc.DocumentNode.SelectSingleNode("/html/body/table/tbody/tr/td/table[2]/tbody/tr/td/table[1]/tbody/tr[1]/td[2]/table[2]/tbody/tr[1]/td/div[2]/div[1]/table/tbody/tr/td/table/tbody/tr[" + i + "]/td[1]") != null)
{
string Code_de_ligne = "";
string Numero_de_produit = doc.DocumentNode.SelectSingleNode("/html/body/table/tbody/tr/td/table[2]/tbody/tr/td/table[1]/tbody/tr[1]/td[2]/table[2]/tbody/tr[1]/td/div[2]/div[1]/table/tbody/tr/td/table/tbody/tr[" + i + "]/td[1]").InnerText;
string Desc_prod = doc.DocumentNode.SelectSingleNode("//tbody/tr[" + i + "]/td[5]/span").InnerText;
string Prix_coutânt = doc.DocumentNode.SelectSingleNode("//tbody/tr[" + i + "]/td[7]/span[2]").InnerText;
string Prix_de_vente = "";
string Qte = doc.DocumentNode.SelectSingleNode("//tbody/tr[" + i + "]/td[6]/input").GetAttributeValue("value", "");
i++;
MessageBox.Show(Code_de_ligne + "|" + Numero_de_produit + "|" + Desc_prod + " | " + Prix_coutânt + "|" + Prix_de_vente + "|" + Qte);
}
but it doesn't give any response in the MessageBox.Show.
I'm executing XPath against this HTML document:

Does the page you're scraping use Javascript or is the HTML ready to parse? Please reduce your XPath expression and your HTML to something postable and post that. Without seeing the HTML (and Minimal, Complete, and Verifiable example), we can't reproduce your situation and then we can not really help you.

Anyone can help me I use Copy Xpath in Google chrome tools developement to get this path :
/html/body/table/tbody/tr/td/table[2]/tbody/tr/td/table[1]/tbody/tr[1]/td[2]/table[2]/tbody/tr[1]/td/div[2]/div[1]/table/tbody/tr/td/table/tbody/tr[2]/td[1]and I use the path in this code to get data :
HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(webBrowser1.Document.GetElementById("tablemasterbleue").InnerHtml);
int i = 2;
while (doc.DocumentNode.SelectSingleNode("/html/body/table/tbody/tr/td/table[2]/tbody/tr/td/table[1]/tbody/tr[1]/td[2]/table[2]/tbody/tr[1]/td/div[2]/div[1]/table/tbody/tr/td/table/tbody/tr[" + i + "]/td[1]") != null)
{
string Code_de_ligne = "";
string Numero_de_produit = doc.DocumentNode.SelectSingleNode("/html/body/table/tbody/tr/td/table[2]/tbody/tr/td/table[1]/tbody/tr[1]/td[2]/table[2]/tbody/tr[1]/td/div[2]/div[1]/table/tbody/tr/td/table/tbody/tr[" + i + "]/td[1]").InnerText;
string Desc_prod = doc.DocumentNode.SelectSingleNode("//tbody/tr[" + i + "]/td[5]/span").InnerText;
string Prix_coutânt = doc.DocumentNode.SelectSingleNode("//tbody/tr[" + i + "]/td[7]/span[2]").InnerText;
string Prix_de_vente = "";
string Qte = doc.DocumentNode.SelectSingleNode("//tbody/tr[" + i + "]/td[6]/input").GetAttributeValue("value", "");
i++;
MessageBox.Show(Code_de_ligne + "|" + Numero_de_produit + "|" + Desc_prod + " | " + Prix_coutânt + "|" + Prix_de_vente + "|" + Qte);
}
but it doesn't give any response in the MessageBox.Show.
I'm executing XPath against this HTML document:

Anyone can help me I use Copy Xpath in Google chrome tools developement to get this path :
/html/body/table/tbody/tr/td/table[2]/tbody/tr/td/table[1]/tbody/tr[1]/td[2]/table[2]/tbody/tr[1]/td/div[2]/div[1]/table/tbody/tr/td/table/tbody/tr[2]/td[1]and I use the path in this code to get data :
HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(webBrowser1.Document.GetElementById("tablemasterbleue").InnerHtml);
int i = 2;
while (doc.DocumentNode.SelectSingleNode("/html/body/table/tbody/tr/td/table[2]/tbody/tr/td/table[1]/tbody/tr[1]/td[2]/table[2]/tbody/tr[1]/td/div[2]/div[1]/table/tbody/tr/td/table/tbody/tr[" + i + "]/td[1]") != null)
{
string Code_de_ligne = "";
string Numero_de_produit = doc.DocumentNode.SelectSingleNode("/html/body/table/tbody/tr/td/table[2]/tbody/tr/td/table[1]/tbody/tr[1]/td[2]/table[2]/tbody/tr[1]/td/div[2]/div[1]/table/tbody/tr/td/table/tbody/tr[" + i + "]/td[1]").InnerText;
string Desc_prod = doc.DocumentNode.SelectSingleNode("//tbody/tr[" + i + "]/td[5]/span").InnerText;
string Prix_coutânt = doc.DocumentNode.SelectSingleNode("//tbody/tr[" + i + "]/td[7]/span[2]").InnerText;
string Prix_de_vente = "";
string Qte = doc.DocumentNode.SelectSingleNode("//tbody/tr[" + i + "]/td[6]/input").GetAttributeValue("value", "");
i++;
MessageBox.Show(Code_de_ligne + "|" + Numero_de_produit + "|" + Desc_prod + " | " + Prix_coutânt + "|" + Prix_de_vente + "|" + Qte);
}
but it doesn't give any response in the MessageBox.Show.
I'm executing XPath against this HTML document:

Actual problem is that XPath queries like //tbody/tr[" + i + "]/td[5]/span returns null, because there is no corresponding span HTML element and so .InnerText crashes with NullReferenceException. Also indexes of td elements (like td[5]) seems to be wrong. Correct XPath is //tbody/tr[" + i + "]/td[6]. But you can rewrite your code to make it much better.
Because you want to iterate through multiple product nodes, it is better to use doc.DocumentNode.SelectNodes() that returns collection of all matching nodes (products) instead of doc.DocumentNode.SelectSingleNode(). Each selected product node looks similar to this:
<tr style="padding: 0px 10px 0px 10px; color:#000000; height:40px;" bgcolor="#EDEDED">
<td align="left" width="125"> <a href="/?ordernow=y&rem=order&prod=1"><img src="http://www.provincialtire.net/images/redcross.png"></a> 00959</td>
<td align="center"><img title="" width="75" height="27" src="http://www.provincialtire.net/provt/images/plugins/logo/UNIR.gif"></td>
<td align="center"> 4 </td>
<td align="left">-</td><td> <img width="30" src="http://www.provincialtire.net/provt/images/plugins/type/W.png"> </td>
<td align="left"> 205/60R16 Tiger Paw Ice & Snow 3 </td>
<td align="right"><div id="each1"><b></b></div></td><td style="background-image:url(/images/special.gif); background-repeat:no-repeat; background-position:top" align="center"><b>95.00</b></td>
</tr>
With this node already selected, you don't need to execute whole complicated XPath query like /html/body/table/tbody/tr/td/table[2]/tbody/tr/td/table[1]/tbody/tr[1]/td[2]/table[2]/tbody/tr[1]/td/div[2]/div[1]/table/tbody/tr/td/table/tbody/tr[" + i + "]/td[1] again to gather desired pieces of information. Execute XPath query only agains HTML node selected above, e.g. node.SelectSingleNode("td[1]"), which is not only much shorter and readable, but also more efficient. Whole code may look like this:
HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(webBrowser1.Document.GetElementById("tablemasterbleue").InnerHtml);
foreach(var node in doc.DocumentNode
.SelectNodes("/html/body/table/tbody/tr/td/table[2]/tbody/tr/td/table[1]/tbody/tr[1]/td[2]/table[2]/tbody/tr[1]/td/div[2]/div[1]/table/tbody/tr/td/table/tbody/tr")
.Skip(1)/*Skip first row containing headers*/)
{
string Code_de_ligne = "";
string Numero_de_produit = node.SelectSingleNode("td[1]").InnerText;
string Desc_prod = node.SelectSingleNode("td[6]").InnerText;
string Prix_coutânt = node.SelectSingleNode("td[8]").InnerText;
string Prix_de_vente = "";
string Qte = node.SelectSingleNode("td[3]").InnerText;
MessageBox.Show(Code_de_ligne + "|" + Numero_de_produit + "|" + Desc_prod + " | " + Prix_coutânt + "|" + Prix_de_vente + "|" + Qte);
}
Because obtained strings may contain excessive HTML entities and spaces like " 00959", you may need to remove them:
// Convert string like " 00959" to just "00959"
Numero_de_produit = HtmlEntity.DeEntitize(Numero_de_produit).Trim();

This means that there is no HTML element that matches requested XPath/html/body/table/tbody/tr/td/table[2]/tbody/tr/td/table[1]/tbody/tr[1]/td[2]/table[2]/tbody/tr[1]/td/div[2]/div[1]/table/tbody/tr/td/table/tbody/tr. In HTML document you provided there are 3 matching nodes, but if you tried with another HTML document, there can be no such element and in that caseSelectNodes()returns null. If you cannot guarantee that at least 1 matching HTML element exists, you'll need to add null-check to deal with such condition.

tablemasterbleue is a class not id and because no method GetElementsByClassName extract get page source with WebBrowser1.DocumentText then loop rows or tr.
the following xpath will select rows in table class tablemasterbleue but skip if has class headerlist which exist in the top and bottom.
doc.LoadHtml(WebBrowser1.DocumentText);
foreach (var node in doc.DocumentNode
.SelectNodes("//table[@class='tablemasterbleue']/tbody/tr[not(contains(@class, 'headerlist'))]"))
{
string Code_de_ligne = "";
string Numero_de_produit = node.SelectSingleNode("td[1]").InnerText;
string Desc_prod = node.SelectSingleNode("td[6]").InnerText;
string Prix_coutânt = node.SelectSingleNode("td[8]").InnerText;
string Prix_de_vente = "";
string Qte = node.SelectSingleNode("td[3]").InnerText;
MessageBox.Show(Code_de_ligne + "|" + Numero_de_produit + "|" + Desc_prod + " | " + Prix_coutânt + "|" + Prix_de_vente + "|" + Qte);
}

Because obtained strings may contain excessive HTML entities and spaces like " 00959", you may need to remove them:

Numero_de_produit = HtmlEntity.DeEntitize(Numero_de_produit).Trim();

This means that there is no HTML element that matches requested XPath/html/body/table/tbody/tr/td/table[2]/tbody/tr/td/table[1]/tbody/tr[1]/td[2]/table[2]/tbody/tr[1]/td/div[2]/div[1]/table/tbody/tr/td/table/tbody/tr. In HTML document you provided there are 3 matching nodes, but if you tried with another HTML document, there can be no such element and in that caseSelectNodes()returns null. If you cannot guarantee that at least 1 matching HTML element exists, you'll need to add null-check to deal with such condition.

Actual problem is that XPath queries like //tbody/tr[" + i + "]/td[5]/span returns null, because there is no corresponding span HTML element and so .InnerText crashes with NullReferenceException. Also indexes of td elements (like td[5]) seems to be wrong. Correct XPath is //tbody/tr[" + i + "]/td[6]. But you can rewrite your code to make it much better.
Because you want to iterate through multiple product nodes, it is better to use doc.DocumentNode.SelectNodes() that returns collection of all matching nodes (products) instead of doc.DocumentNode.SelectSingleNode(). Each selected product node looks similar to this:
<tr style="padding: 0px 10px 0px 10px; color:#000000; height:40px;" bgcolor="#EDEDED">
<td align="left" width="125"> <a href="/?ordernow=y&rem=order&prod=1"><img src="http://www.provincialtire.net/images/redcross.png"></a> 00959</td>
<td align="center"><img title="" width="75" height="27" src="http://www.provincialtire.net/provt/images/plugins/logo/UNIR.gif"></td>
<td align="center"> 4 </td>
<td align="left">-</td><td> <img width="30" src="http://www.provincialtire.net/provt/images/plugins/type/W.png"> </td>
<td align="left"> 205/60R16 Tiger Paw Ice & Snow 3 </td>
<td align="right"><div id="each1"><b></b></div></td><td style="background-image:url(/images/special.gif); background-repeat:no-repeat; background-position:top" align="center"><b>95.00</b></td>
</tr>
With this node already selected, you don't need to execute whole complicated XPath query like /html/body/table/tbody/tr/td/table[2]/tbody/tr/td/table[1]/tbody/tr[1]/td[2]/table[2]/tbody/tr[1]/td/div[2]/div[1]/table/tbody/tr/td/table/tbody/tr[" + i + "]/td[1] again to gather desired pieces of information. Execute XPath query only agains HTML node selected above, e.g. node.SelectSingleNode("td[1]"), which is not only much shorter and readable, but also more efficient. Whole code may look like this:
HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(webBrowser1.Document.GetElementById("tablemasterbleue").InnerHtml);
foreach(var node in doc.DocumentNode
.SelectNodes("/html/body/table/tbody/tr/td/table[2]/tbody/tr/td/table[1]/tbody/tr[1]/td[2]/table[2]/tbody/tr[1]/td/div[2]/div[1]/table/tbody/tr/td/table/tbody/tr")
.Skip(1)/*Skip first row containing headers*/)
{
string Code_de_ligne = "";
string Numero_de_produit = node.SelectSingleNode("td[1]").InnerText;
string Desc_prod = node.SelectSingleNode("td[6]").InnerText;
string Prix_coutânt = node.SelectSingleNode("td[8]").InnerText;
string Prix_de_vente = "";
string Qte = node.SelectSingleNode("td[3]").InnerText;
MessageBox.Show(Code_de_ligne + "|" + Numero_de_produit + "|" + Desc_prod + " | " + Prix_coutânt + "|" + Prix_de_vente + "|" + Qte);
}

tablemasterbleue is a class not id and because no method GetElementsByClassName extract get page source with WebBrowser1.DocumentText then loop rows or tr.
the following xpath will select rows in table class tablemasterbleue but skip if has class headerlist which exist in the top and bottom.
doc.LoadHtml(WebBrowser1.DocumentText);
foreach (var node in doc.DocumentNode
.SelectNodes("//table[@class='tablemasterbleue']/tbody/tr[not(contains(@class, 'headerlist'))]"))
{
string Code_de_ligne = "";
string Numero_de_produit = node.SelectSingleNode("td[1]").InnerText;

Does the page you're scraping use Javascript or is the HTML ready to parse? Please reduce your XPath expression and your HTML to something postable and post that. Without seeing the HTML (and Minimal, Complete, and Verifiable example), we can't reproduce your situation and then we can not really help you.
