find element by xpath with contains(node()) AND contains(#attribute) - selenium

Question

I'm trying to locate an element by checking innerHTML (property node()) and some attribute (e.g. #class).
Both methods works separately but I can't combine them with "and"
HTML part:
<tr class="tableRow1">
<td nowrap="" class="ct">
<input type="CheckBox" name="RowKey" tabindex="17" value="15635">
<img src="/tm/images/1pixel.gif" style="height:9px;width:9px;border:0" name="RowIndicator">
</td>
<td class="lt" title="ID">XXXXX</td><nobr>0021234567</nobr><td class="rt">1.00</td>
</tr>
So I need to locate this node of class="tableRow1" (from many others) by catching this part:
<nobr>002123456</nobr>.
This two works (but catching several elements):
.find_element_by_xpath('//tr[contains(node(), "0021234567")]')
.find_element_by_xpath('//tr[contains(#class, "Row")]')
This one doesn't:
.find_element_by_xpath('//tr[contains(node(),"0021234567") and contains(#class,"Row")]')

Answer 1

Try this XPath-1.0 expression:
descendant::*[contains(node(), "0021234567")]/ancestor::tr[contains(#class, "Row")][1]
or in a complete instruction
.find_element_by_xpath('descendant::*[contains(node(), "0021234567")]/ancestor::tr[contains(#class, "Row")][1]')
This instruction selects the first tr ancestor - which has a class attribute which contains the value Row - of a (global) node() which contains the value 0021234567.

Answer 2

Your two XPath selectors are selecting different nodes.
The node that contains the string is a descendant of the <tr> node with the class name. That is why when you are putting both conditions for one node it doesn't find any matching node.
Try this:
.find_element_by_xpath('//[contains(node(), "0021234567")]/ancestor::tr[contains(#class), "Row"]')

Answer 3

To locate the <tr> nodes which contains the child <nobr> nodes you can use the following solution:
driver.find_element_by_xpath("//nobr//ancestor::tr[contains(#class, 'Row')]")
Note: It is assumed that the innerText within the <nobr> is a variable else the innerText can be included within the XPath expression as well.

Answer 4

So I need to locate this node of class="tableRow1" (from many
others) by catching this part:
<nobr>002123456</nobr>
The XPath expression should be:
//tr[#class='tableRow1'][.//nobr='002123456']
That is the basic. Then you could adjust that to your situation.
Example 1 (many posible classes tokens):
//tr[contains(concat(' ',#class,' '),' tableRow1 ')][.//nobr='002123456']
Example 2 (posible white space in nobr):
//tr[contains(concat(' ',#class,' '),' tableRow1 ')]
[.//nobr[normalize-space()='002123456']]
Example 3 (class token starts with 'tableRow'):
//tr[contains(concat(' ',#class,' '),' tableRow')]
[.//nobr[normalize-space()='002123456']]
