[xpath]Need help in getting xpath for a table row next to another

EDIT: Why was this voted down? I really have no idea... BTW ../ does not work since i don't want the parent of the Table but want actually ../td+1 i don't know if that is even possible?

Hi guys.

I have a fairly complex problem at hand..

I have a table like this:

Name | Result | AutotestID | AutotestResult | AutotestName

X | Pass | X86HZS1 | | |

So... What i want to do is the following. I know only the ID. And i'd like to update the AutotestResult from an autotest. Which is empty to begin with.

I'm trying to locate the ID... I have that. But then when i have the ID i must update the Row next to it. How do i do that? I tried playing with the xPath. Stepping backwards using ../../../td etcetc but with no luck.

I can't seem to find its neighboring table...

Could somebody please point me into the right direction?

Thanks very much for every help!

Your question is unclear but I'm doing some guessing and presume you have an XHTML file

<table>
  <tr>
    <td>Name</td>
    <td>Result</td>
    <td>AutotestID</td>
    <td>AutotestResult</td>
    <td>AutotestName</td>
  </tr>
  <tr>
    <td>X</td>
    <td>Pass</td>
    <td>X86HZS1</td>
    <td></td>
    <td></td>
  </tr>
</table>

and you are trying to create an XPath expression that selects the next <td> element after the one that contains text "X86HZS1" (the AutotestID). To find a node with certain text content you can use a predicate and the sibling elements that appear after this node in the document order you get by using axis following-sibling. A proper XPath expression would be

//td[.='X86HZS1']/following-sibling::td[1]

If the same AutotestID you are matching appears several times in your table data, this expression matched all of them and would return a node set instead of a single node.

Edit: Generally using // when not neccessary is not recommended since it requires traversing through the whole document. Using a more direct path, like mentioned in comments, results in more efficient XPath expression.

Besides jasso's good recommendation of following-sibling axis, there is some problem with that answer: you must fix what td is the AutotestID.

So, knowing the table' schema:

<table> 
  <tr> 
    <td>Name</td> 
    <td>Result</td> 
    <td>AutotestID</td> 
    <td>AutotestResult</td> 
    <td>AutotestName</td> 
  </tr> 
  <tr> 
    <td>X</td> 
    <td>Pass</td> 
    <td>X86HZS1</td> 
    <td></td> 
    <td></td> 
  </tr> 
</table>

You could use:

/table/tr/td[3][.='X86HZS1']/following-sibling::td[1]

or

/table/tr[td[3]='X86HZS1']/td[4]

If you don't know the AutotestID position, you could use:

/table/tr/td[count(../../tr/td[.='AutotestID']/preceding-sibling::td)+1]
            [.='X86HZS1']/following-sibling::td[1]
