Please take a look at the snippet of html below:
<tr class="clickable">
<td id="7b8ee8f9-b66f-4fba-83c1-4cf2827130b5" class="clickable">
<a class="editLink" href="#">Single</a>
</td>
<td class="clickable">£14.00</td>
</tr>
I'm trying to assert the value of td[2] when td[1] contains "Single". I've tried assorted variants of:
//td[2][(contains(text(),'£14.00'))]/../td[1][(contains(text(),'Single'))]
I've used similar notation elsewhere successfully - but to no avail here... I think it's down to td[1] having the nested element, but not sure.
Can someone enlighten as to what I'm getting wrong? :)
Cheers!
What about:
//tr[contains(td[1], "Single")]/td[2]
First select the <tr> containing the <td> matching the text, and then select td[2].
Then,
contains(//tr[contains(td[1], "Single")]/td[2], "£14.00")
should return True.
Or, closer to the expression you tried, you could test if this matches:
//tr[contains(td[1], "Single")]/td[2][contains(., "£14.00")]
See #JensErat's answer to find xth td with td contains in same tr xpath python .
Why not make it simple on yourself, do the if statement in your code. Psuedocode:
Select the top level tr.
Find first td within tr, check to see if it contains Single.
If it does, assert that it contains £14.00
Alternatively, you could just get the text of the top level tr and perform the checks on that text.

I want to select the next sibling of a td tag in a tr element.
The tr element is this:
<tr>
<td>Created On:</td>
<td>06/28/2018 06:32 </td>
</tr>
My Scrapy code looks like this: response.xpath("//text()[contains(.,'Created On:')]/following-sibling::td"). But that gives me an empty list [].
How do I select the next td?
Try this XPath expression:
//text()[contains(.,'Created On:')]/../following-sibling::td
You were trying to use the following-sibling axis from the wrong context node. Going back one level fixes this problem.
An alternative is matching the td element in the first place like in this expression:
//td[contains(text(),'Created On:')]/following-sibling::td
This is my html code:
<tr>
<th class="left_cont"><strong>Hello world</strong></th>
<td class="right_cont padding_left16px"><strong>Hi There</strong></td>
</tr>
Now to select the text Hellow world i used.
//strong[contains(text(),'Hello world')]
Works fine for me.
Now I need to select the text Hi there relatively to the hello world text.
I need to do something like this but I can't figure out.
//strong[contains(text(),'Hello world')]/following-sibling::strong
Doesn't work out for me.
Elements with sibling relations are parent of <strong> instead of <strong> it self, so you can try this way :
//*[strong[contains(.,'Hello world')]]/following-sibling::*[strong]/strong
Or if you are sure parents involved are always <th> and <td> :
//th[strong[contains(.,'Hello world')]]/following-sibling::td[strong]/strong
2nd "strong" element is not actually sibling of the first one. But wrapping "td" elements are siblings. So you could probably use
//strong[contains(text(),'Hello world')]/../following-sibling::td/strong
I am newbie in XPath. Can someone explain how to resolve this problem:
<table>
<tr>
<td>
<table>
<tr>
<td>
<table>
<tr>
<td>Label</td>
<td>value</td>
</tr>
</table>
</td>
</tr>
</table>
</td>
</tr>
</table>
I try to get <tr> which contains Label value, but it does not work for me,
Here is my code :
//td[contains(.,'Label')]/ancestor::tr[1]
Desired result:
<tr>
<td>Label</td>
<td>value</td>
</tr>
Can someone help me ?
This expression matches the tr that you want:
//tr[contains(td/text(), 'Label')]
Like yours, this starts by scanning all tr elements in the document, but this version uses just a single predicate. The td/text() limits the test to actual text nodes which are grandchildren of the row. If you just used td, then all of the td's descendant text nodes would be collected and concatenated, and the outer tr would match.
UPDATE: Also, for what it's worth, the reason your expression isn't working is that the ancestor axis returns elements in document order, not "outward" from the point of the context node. This is something I've run into myself, as it is somewhat unintuitive. To make your approach work, you would need to say
//td[contains(.,'Label')]/ancestor::tr[last()]
instead of
//td[contains(.,'Label')]/ancestor::tr[1]
I had the same issue, except that the text 'Label' was sometimes in a nested span, or even further nested in the td. For example:
<td><span>Label</span></td>
The previous answer only finds 'Label' if it is in a text element that is a direct child of the td. This issue is a bit harder because we need to search for a td that contains the text 'Label' in any of its children. Since the tds are nested, all tds qualify as having a descendant that contains the text 'Label'. So, the only way I found to overcome this is to add a check that makes sure that the td we select does not contain a td with the search text.
//td[contains(., 'Label') and not(.//td[contains(., 'Label')])]/ancestor::tr[1]
This says give me all of the tds that have a decedent text containing 'Label', but exclude all tds that contain a td that has a decedent text containing 'Label' (nesting ancestors). This returns the child most td that contains the text. Then you can go back to the tr that contains this td using ancestor.
Also, if you just want the lowest table that contains text use this:
//table[contains(., 'Label') and not(.//table[contains(., 'Label')])]
or you can select the tr directly:
//tr[contains(., 'Label') and not(.//tr[contains(., 'Label')])]
This seems like a common problem, but I didn't see a solution anywhere. So, I decided to post to this old unanswered question in hopes that it helps somebody.
I have this piece of html:
<tr>
<td class="has-checkbox">
<input id="abc" class=... value=...>
</td>
<td class="has-label">
<label for="abc">Name1234</label>
</td>
<tr>
I need to make an xpath that gets me the input element, based on whats in the label, in this case Name1234.
In other words, for this case, I need an xpath to the input element, and the path must contain Name1234, as its variable.
Anyone who can help me out here?
//input[#id = //label[. = 'Name1234']/#for] selects input element(s) with an id attribute value equal to the for attribute value of label elements where the contents is Name1234.
You can use /.. , this syntax use to move back to parent node. In your case:
//label[.='Name1234']/../../td/input
You must move back 2 times because input tag is the child of another td tag.
Here are others introduction and example about you should read.
Here is a solution using the Axes parent and preceding-sibling:
//label[.='Name1234']/parent::td/preceding-sibling::td/input
It's not so complicated as you think:
xpath=//tr[//label[.="Name1234"]]//input
in other words, you are looking for the 'tr' which contains 'label' with text "Name1234". If the condition is true, you are getting the 'input' element
I have trouble parsing a HTML table using Nokogiri and Ruby. My HTML table structure looks like this
<table>
<tbody>
<tr>
<td>Firstname</td>
<td>Lastname</td>
<td>Middle</td>
</tr>
<tr>
<td>ding</td>
<td>dong</td>
<td>ling</td>
</tr>
....
....
.... {more tr's and td's with similar data exists.}
....
....
....
....
....
</tbody>
</table>
In the above HTML table I would like to entirely remove the first and corresponding elements, so remove Firstname, Lastname and Middle i.e., I want to start stripping the text only from the second . So this way I get only the contents of the table from the second or tr[2] and no column headers.
Can someone please provide me a code as to how to do this.
Thanks.
require 'rubygems'
require 'nokogiri'
doc = Nokogiri::HTML(x)
rows = doc.xpath('//table/tbody/tr[position() > 1]')
# OR
rows = doc.xpath("//table/tbody/tr")
header = rows.shift
After you've run either one of the above 2 snippets, rows will contain every <tr>...</tr> after the first one. For example puts rows.to_xml prints the following:
<tr><td>ding</td>
<td>dong</td>
<td>ling</td>
</tr>
To get the inner text, removing all the html tags, run puts rows.text
ding
dong
ling
To get the inner text of the td tags only, run rows.xpath('td').map {|td| td.text }
["ding", "dong", "ling"]
Alternatively:
table.css('tr')[1..-1]
or to strip out the text starting at row 2:
table.css('tr')[1..-1].map{|tr| tr.css('td').map &:text}
Since Nokogiri does support :has CSS pseudo-class you can get heading row with
#doc.at_css('table#table_id').css('tr:has(th)')
and since it does supports :not CSS pseudo-class as well, you can get other rows with
#doc.at_css('table#table_id').css('tr:not(:has(th))')
respectively. Depending on your preferences you might like to avoid negation and just use css('tr:has(td)').
