What XPath selects the next <tr> after a <tr> containing X?
XhtmlXpathXhtml Problem Overview
<tr>
<td>Blah!</td>
<td>X</td> <!-- TR containing X -->
<td>Woot!</td>
</tr>
<tr>
<td>Useful Data, contents unknown</td> <!-- Select this TR -->
</tr>
<tr>
<td>Useless data</td> <!-- Don't select this or any subsequent TR -->
</tr>
<tr>
<td>More crap I don't want</td>
</tr>
<tr>
<td>X</td> <!-- Another X -->
</tr>
<tr>
<td>Useful</td> <!-- Do select this one, since previous has X -->
</tr>
What XPath would return the <tr> immediately following the <tr> that contains X?
Xhtml Solutions
Solution 1 - Xhtml
ChaosPandion's and Martin v. Löwis's answers both work for the sample you give, but if you are asking for the next tr, then presumably in some cases there are further tr elements in same table. In which case, the answers will give all the following or following-sibling tr elements.
Also going by the headline question rather than the sample, the xpath should probably allow for the X being in a th cell instead of td. And I'm guessing that you'd only want the following tr if it is in the same parent (thead, tbody, tfoot).
So I'd go for
//tr[* = 'X']/following-sibling::tr[1]
Solution 2 - Xhtml
This should work.
tr[td/text() = 'X']/following-sibling::node()
Solution 3 - Xhtml
//td[.='X']/following::tr
Solution 4 - Xhtml
Use this for finding the next element from your element. Keep increasing for every hop:
//android.widget.TextView[contains(@text,'US Dollar')]/following::android.widget.TextView[1]
