Retrieve the table data with xpath and Selenium - c#

I have HTML with looks basically like the following
....
<div id="a">
<table class="a1">
<tbody>
<tr>
<td><a href="a11.html>a11</a>
</tr>
<tr>
<td><a href="a12.html>a12</a>
</tr>
</tbody>
<table>
</div>
...
The following coding in C# I used, however, I cannot retrieve the URL in this stage
IWebElement baseTable = driver.FindElement(By.ClassName(TableID));
// gets all table rows
ICollection<IWebElement> rows = baseTable.FindElements(By.TagName("tr"));
// for every row
IWebElement matchedRow = null;
foreach(var row in rows)
{
Console.Write (row.FindElements(By.XPath("td/a")));
}

First of all, you gave us invalid markup. Right one:
<div id="a">
<table class="a1">
<tbody>
<tr>
<td>
a11
</td>
</tr>
<tr>
<td>
a12
</td>
</tr>
</tbody>
</table>
</div>
If you have only one anchor in table row, you should use this code to retrieve url:
IWebElement baseTable = driver.FindElement(By.ClassName(TableID));
// gets all table rows
ICollection<IWebElement> rows = baseTable.FindElements(By.TagName("tr"));
// for every row
IWebElement matchedRow = null;
foreach (var row in rows)
{
Console.WriteLine(row.FindElement(By.XPath("td/a")).GetAttribute("href"));
}
You need to get href attribute of found element. Otherwise, row.FindElement(By.XPath("td/a") will print type name of the IWebElement inherited class, because it is an some type object, not string.

This does not look like a valid xpath to me
Console.Write (row.FindElements(By.XPath("td/a")));
try
Console.Write (row.FindElements(By.XPath("/td/a")));

ASP-routing from tavlerow instead of anchor

I'm trying to learn asp.net and I'm trying to use the ASP routing directly from the tablerow (tr), instead of for each anchor point inside the cell.
Below code, I'm able to click the "Case ID" in my table, but this leaves some unclickable area around the actual text. I basically want to be able to simply select the row and pass the #sc.ID for a database query in the ViewCase-page.I want end-user to click "category" (and several columns in the future), without having to define tags everyhwere.
#foreach (var sc in Model.Cases)
{
<tr asp-area="" asp-page="ViewCase" asp-route-ID="#sc.ID">
<td>
<a asp-area="" asp-page="ViewCase" asp-route-ID="#sc.ID">
Case #Html.DisplayFor(Moldel => #sc.ID)
</a>
</td>
<td>
#Html.DisplayFor(Moldel => #sc.Category)
</td>
</tr>
}
It seems you do not want not want to specify the a tag every where. Tag helper does not work for table element, you just add js in the tr element like below:
<table class="table">
#foreach (var sc in Model.Cases)
{
<tr onclick="window.location.href='/ViewCase?ID=#sc.ID'">
<td>
Case #Html.DisplayFor(Moldel => #sc.ID)
</td>
<td>
#Html.DisplayFor(Moldel => #sc.Category)
</td>
</tr>
}
</table>

How do I get my XPath to search only within each table?

I have a bit of HTML that looks like this:
<table class="resultsTable">
<tbody>
<tr class="even">
<td width="35%"><strong>Name</strong></td>
<td>ACME ANVILS, INC</td>
</tr>
</tbody>
</table>
and some C# code that looks like this:
var name = document.DocumentNode
.SelectSingleNode("//*[text()='Name']/following::td").InnerText
which happily returns
ACME ANVILS, INC.
However, there's a new wrinkle. The page in question now returns multiple results:
<table class="resultsTable">
<tbody>
<tr class="even">
<td width="35%"><strong>Name</strong></td>
<td>ACME ANVILS, INC.</td>
</tr>
</tbody>
</table>
<table class="resultsTable">
<tbody>
<tr class="even">
<td width="35%"><strong>Name</strong></td>
<td>ROAD RUNNER RACES, LLC</td>
</tr>
</tbody>
</table>
So now I'm working with
var tables = document.DocumentNode.SelectNodes("//table/tbody");
foreach (var table in tables)
{
var name = table.SelectSingleNode("//*[text()='Name']/following::td").InnerText;
...
}
Which falls over, because SelectSingleNode returns null.
How do I get my XPath to actually return a result, searching only within the specific table I have selected?
With the addition of a second table, two adjustments are required:
Change your absolute XPath,
//*[text()='Name']/following::td
to one relative to the current table or tbody element:
.//*[text()='Name']/following::td
Account for there now being more than one td element on the
following:: axis.
Either just grab the first,
(.//*[text()='Name']/following::td)[1]
or, better, use the following-sibling:: axis instead in combination
with a test on the string value of td rather than a test on a text node, which might be buried beneath intervening formatting elements:
.//td[.='Name']/following-sibling::td

JQuery: Losing Styles after ajax query succes where I am adding data

I have a table which via ajax I get n rows, after success I add to the tbodyo the table. I dont know why I am losing styles
My table is:
<table id="Pedidos">
<thead>
<tr>
<th>field 1</th>
<th>field 1</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
After to add data In Jquery I have
...
function onSuccessOrder(data) {
jQuery("#Pedidos tbody").empty().append(data);
}
...
PageMethods.OrdenarTabla(1, "DESC", onSuccessOrder);
In OrdenarTabla I set data i need:
...
string row = #"
<tr>
<td class=""check"">{0}</td>
<td>{1}</td>
</tr>";
return row;
...
Why Am I losing the styles? what is wrong?
I got the solution:
jQuery("#Pedidos tbody").empty().append(data);
jQuery("#tbPedidos tbody").find('input:checkbox').uniform({ selectAutoWidth: true });

Multiplying a textbox with a cell in a dynamically created table with JQuery

I have a dynamically created table with id called "editTable" that looks as follows:
<tbody>
#{var i = 0;}
#foreach (var item in Model)
{
<tr>
<td width="25%">
#Html.DisplayFor(modelItem => item.Product.Name)
</td>
<td width="25%">
#Html.DisplayFor(modelItem => item.Quantity)
</td>
<td width="25%">
<div class="editor-field">
#Html.EditorFor(modelItem => item.UnitPrice)
#Html.ValidationMessageFor(model => item.UnitPrice)
</div>
</td>
<td width="25%" id="total"></td>
</td>
</tr>
}
</tbody>
The 3th td-element consists of a C# textbox that is turned into a element in html.
Now I want to multiply the quantity by the unit price to display this value in the 4th td element next to it. This value should update every time the value in the textbox is adjusted. I am a newbie at JQuery / JavaScript and came up with the following code:
// Calculating quantity*unitprice
$('#editTable tr td:nth-child(3) input').each( function (event) {
var $quant = $('#editTable tr td:nth-child(2)', this).val();
var $unitPrice = $('#editTable tr td:nth-child(3) input', this).val();
$('#editTable tr td:nth-child(4)').text($quant * $unitPrice);
});
This doesn't work and only displays NaN in the 4th element. Can anyone help me updating this code to a working version? Any help would be very much appreciated.
I geussed you accidentally switched units and price because it has more logic to change the number of units then the price. I took your html and javascript and tried to change as little as possible to make it work (I'm not saying the solution is perfect, I just don't want to give you a totaly different example of how to do it).
The html (The C# is irrelevant for this problem):
<table id="editTable">
<tbody>
<tr>
<td width="25%">
Product name
</td>
<td width="25%">
5
</td>
<td width="25%">
<div class="editor-field">
<input id="UnitPrice" name="UnitPrice" type="number" value="2" style="width:40px" />
</div>
</td>
<td width="25%" id="total"></td>
</tr>
</tbody>
</table>
The javascript/jquery (which should run on load):
$('#editTable tr td:nth-child(3) input').each(updateTotal);
$('#editTable tr td:nth-child(3) input').change(updateTotal);
var element;
function updateTotal(element)
{
var quantity = $(this).closest('tr').find('td:nth-child(2)').text();
var price = $(this).closest('tr').find('td:nth-child(3) input').val();
$(this).closest('tr').find('td:nth-child(4)').text(quantity * price);
}
The problem you had were with jquery. I've created a function that recieves an element (in our case it's your UnitPrice input), then it grabs the closest ancestor of type tr (the row it's in) and from there it does what you've tried to do.
You've used jquery selector to get all 2nd cells in all table rows, the closest('tr').find limits it to the current row.
You've tried to use .val() on a td element, you should use either .text() or .html(). Instead, You can also add a data-val="<%=value%>" on the td and then use .data('val').
It will be better to take the units directly from $(element).val() and no going to the tr and then back into the td and the input.
To see it working: http://jsfiddle.net/Ynsgf/1/
I hope I didn't caused you any confusion with my explanation and the options I gave you.
Here is another way to write the jquery part.
$('#editTable tr').each(function (i, row) {
var $quant = $(row).find('.editor-field input').val();
var $unitPrice = $(row).find('.editor-field input').val();
$(row).find('td:nth-child(4)').text($quant * $unitPrice);
});

HTMLAgilityPack - Detecting a blank table?

I'm using c# with htmlagilitypack. Everything works fine except when the table I'm looking for contains no rows. I'm trying to read only the data from the 1st table on the page. The problem is if the first table contains no rows, the htmlagilitypack seems to jump down to the 2nd table for some reason.
The html I'm trying to read looks something like this:
<table class='stats'>
<tr>
<td colspan='2'>This is the 1st table</td>
<tr>
<td>Column A</td>
<td>Column B</td>
</tr>
<tr>
<td>Value A</td>
<td>Value B</td>
</tr>
</table>
<table class='stats'>
<tr>
<td colspan='2'>This is the 2nd table</td>
<tr>
<td>Column 1</td>
<td>Column 2</td>
</tr>
<tr>
<td>Value 111</td>
<td>Value 222</td>
</tr>
</table>
I then retrieve the 1st table's values using the following line:
foreach (HtmlNode node in root.SelectNodes("//table[#class='stats']/tr[position() > 2]/td"))
How do I ensure the data I'm grabbing is only from the 1st table?
Thanks.
You could ensure that you only select the first matching table by using a position index [1] after the table selector.
Try the following:
"//table[#class='stats'][1]/tr[position()>2]/td"
If the first table has no rows, then you will get null back so you should check for that before iterating in the foreach.
For example you might want to do the following:
var elements = root.SelectNodes("//table[#class='stats'][1]/tr[position()>2]/td");
if (elements != null)
{
foreach (HtmlNode node in elements)
{
// process the td node
}
}
You need to have an id on the table or row which uniquely identifies the table or or and then use the id in the xpath.
