Consider the below table structure contains many rows with multiple column values. I need to identify the parent of specific row, which has to be identified using the cell .
<table class = 'grid'>
<thead id = 'header'>
</thead>
<tbody>
<tr>
<td>
<span class="group">
<span class="group__link"><a class="disabledlink"">copy</a>
</span>
</span>
</td>
<td class="COLUMNNAME">ACE</td>
<td class="COLUMNLONGNAME">Adverse Childhood Experiences</td>
<li>Family Medicine</li>
<li>General Practice</li>
</td>
<td class="COLUMNSEXFILTER">Both</td>
<td class="COLUMNAGEFILTERMIN">Any</td>
<td class="COLUMNTYPE">Score Only</td>
</tr>
<tr>
<td class="nowrap" showactionitem="2">
<span class="group">
<span class="group__link"><a onclick="Check()" href="#">copy</a>
</span>
</span>
</td>
<td class="COLUMNNAME">AM-PAC</td>
<td class="COLUMNLONGNAME">AM-PAC Generic Outpatient Basic Mobility Short Form</td>
<td class="COLUMNNOTE"></td>
<td class="COLUMNRESTRICTEDYN">No</td>
<td class="COLUMNSPECIALTYID"></td>
<td class="COLUMNSEXFILTER">Both</td>
<td class="COLUMNAGEFILTERMIN">Any</td>
<td class="COLUMNTYPE">Score Only</td>
</tr>
<tr></tr>
<tr></tr>
</tbody></thead>
</table>
Likewise this table contains around 100 rows. I did the same using iteration and it is working fine.
Is it possible to find the parent of specific row without iteration?
You can use the parent method to find the parent of an element. Assuming that you have located a table cell, let's call it cell, you can get its row using parent and then the parent of the row with another call to parent:
cell.parent
#=> a <tr> element
cell.parent.parent
#=> the parent of the specific row - a <tbody> element in this case
Chaining multiple parent calls can become tedious and difficult to maintain. For example, you would have to call parent 4 times to get the table cell of the "copy" link. If you are after an ancestor (ie not immediate parent), you are better off using XPath:
cell.table(xpath: './ancestor::table')
#=> the <table> element containing the cell
browser.link(text: 'copy').tr(xpath: './ancestor::tr')
#=> the <tr> element containing a copy link
Hopefully Issue 451 will be implemented soon, which will remove the need for XPath. You would be able to call:
cell.parent(tag_name: 'table') # equivalent to `cell.table(xpath: './ancestor::table')`
There's no need for anything fancy, Watir has an Element#parent method.
You can use this one:
parent::node()
The below example will selects the parent node of the input tag of Id='email'.
Ex: //input[#id='email']/parent::*
the above can also be re-written as
//input[#id='email']/..

I have the follow html file:
<table class="pd-table">
<caption> Tech </caption>
<tbody>
<tr data-group="1">
<td> Electrical </td>
<td> Design </td>
<tr data-group="1">
<td> Output </td>
<td> Function </td>
<tr data-group="7">
<td> EMC </td>
<table>
<tbody>
<tr>
<td> EN 6547 ESD </td>
<td> EN 8901 ESD </td>
<tr data-group="8">
<td> Weight [8] </td>
<td> 27.7 </td>
I can isolate EN 6547 ESD and EN 8901 ESD with the follow xpath:
//table[#class="pd-table"]//tbody//tr//td/table//tr//td/text()').getall()
Any other way is always welcome :)
Another data which I would like to get is to get all the rest of the data without the previous isolated.
Is there any way to do it? :)
Looks like table tag is not closed properly in data-group-7...
Anyway in such cases you can stick to text content of the cell using contains() or text()="some exact text"
response.xpath('//td[contains(text(), "EMC")]').css('td~table tbody td::text').extract()
Your used Xpath uses a lot of unwanted double slash.
See meaning of double slash in Xpath.
The less you use double slash, the better it will perform.
So just use single slash like this:
//table[#class="pd-table"]/tbody/tr/td/table/tr/td/text()
Another way of selecting td's that have two ancestor::table
//td[count(ancestor::table)=2]/text()
And that leads to the answer of your second question:
//td[count(ancestor::table)=1]/text()
An other possibility would just be:
//table[#class="pd-table"]/tbody/tr/td/text()
Or(assuming the second tabel does not have tr's with #data-group):
//tr[#data-group]/td/text()
So you see there are many Xpath's lead to Rome ;-).
I have a dynamic web table and I want to select the node on the basis of text value of two different text attributes.
//tr[.//td[contains(text(),'SATWIK GHANSIYAL')] and .//td[contains(text(),'07/07/2002')]]
HTML:

I am getting the massage no element found
use this.
//tr[.//td[contains(.,'SATWIK GHANSIYAL')] and .//td[contains(.,'07/07/2002')]]
trying to evaluate this expression based on the given xml
//tr[.//td[contains(text(),'SATWIK GHANSIYAL')] and .//td[contains(text(),'07/07/2002')]]
text() is returning multiple sequence, thus giving me this error message.
Unable to perform XPath operation. A sequence of more than one item is not allowed as the first argument of contains() ("", "")
I am trying to achieve following matrix kind of layout:
TABLE1,1 TABLE1,2
CHART2,1 TABLE2,2
TABLE3 --> occupies whole row
CHART4 --> ocupies whole row
CHART5,1 CHART5,2
................. List goes on...
These components may span over multiple pages. What is the best way to have them side by side and still be able to view them in MigraDoc.
CHART5,1 could be a combination of 4 charts in one cell.
In HTML view I can use following analogy:
<TABLE>
<TR>
<TD>TABLE1,1</TD> <TD>TABLE1,2 </TD>
</TR>
<TR>
<TD>CHART2,1</TD> <TD>TABLE2,2 </TD>
</TR>
<TR>
<TD>TABLE3</TD colspan =2>
</TR>
<TR>
<TD>CHART4</TD colspan =2>
</TR>
<TR>
<TD>CHART5,1</TD> <TD>CHART5,2 </TD>
</TR>
</TABLE>
The MigraDoc equivalent for colspan=2 is MergeRight=1. This is a property of the Cell class.
Looking for a xpath node whose table row must fulfill several conditions
Searching for those node "col_functions" whose table row values is "John Wayne" from the table #class="table_list".
("col_functions", "col_firstname" and "col_lastname are sibling nodes and childs from the table)
<table class="table_list">
<tbody>
<tr>
<td class="col_firstname">John</td>
<td class="col_lastname">Lennon</td>
<td class="col_functions"></td>
</tr>
<tr>
<td class="col_firstname">John</td>
<td class="col_lastname">Wayne</td>
<td class="col_functions"></td> <=== looking for this node!!
</tr>
<tr>
<td class="col_firstname">Wayne</td>
<td class="col_lastname">John</td>
<td class="col_functions"></td>
</tr>
</tbody>
<table>
One option would be to check for class names all over the place:
//table[#class="table_list"]//tr[td[#class="col_firstname"] = "John" and td[#class="col_lastname"] = "Wayne"]/td[#class="col_functions"]/text()
Here we are basically checking all rows inside the table for cells with first name John and last name Wayne, getting the cell with col_functions as an output.
Using siblings it will be like that:
//table[#class='table_list']//td[#class='col_firstname'][text()='John']/following-sibling::td[#class='col_lastname'][text=()'Wayne']/following-sibling::td[#class='col_functions']

I tried with this:
/html/body/div/div/div/div/div/div/div/table/tbody/tr/td/table/tbody/tr[1]/td[2]
but nothing appears. Can someone help me with the right syntax to obtain "Grupo Profissional"?
Quick answer that might work
Considering just the HTML sample you provided (which only has two tables) you can select the text you want using this expression, based on the table's position:
//table[2]//tr[3]/td[1]/text()
This will work in the HTML you pasted above. But it might not work in your actual scenario, since you might have other tables, the table you want to select has no ID and you didn't suggest some invariant text in your code which could be used to anchor the context for the expression. Assuming the initial part of your XPath expression (the div sequence) is correct, you might be able to use:
/html/body/div/div/div/div/div/div/div/table[2]//tr[3]/td[1]/text()
But it's wuite a fragile expression and vulnerable to any changes in the document.
A (possibly) better solution
A better alternative is to look for some identifier you could use. I can only guess, since I don't know your code. In your sample code, I would guess that Codigo and the number following it 206415 might be some identifier. If it is, you could use it to anchor your context. First you select it:
//table[.//td[text()='Código:']/following-sibling::td='206415']
The expression above will select the table which contains a td with the exact text Código: followed by a td containing the exact text 206415. This will create a unique context (considering that the number is an unique identifier). From that context, you can now select the text you want, which is inside the next table (following-sibling::table[1]). This is the context of the second table:
//table[.//td[text()='Código:']/following-sibling::td='206415']/following-sibling::table[1]
And this should select the text you want (Grupo profissional:) which is in the third row tr[3] and first cell/column td[1] of that table:
//table[.//td[text()='Código:']/following-sibling::td='206415']/following-sibling::table[1]//tr[3]/td[1]/text()
