XPath - Get row/cell with no specified child-CodePudding

I have HTML like that:

 <tbody>
    <tr>
    <td >
       <img src="lock.img" alt="Row locked">
    </td>
    <td >
    </td>
    <td >
    </td>
    <td >
    </td>
</tbody>

I would like to create xpath which select for me first which is unlocked.
Only locked ID has xpath .//td/img.

I created something like that:
.//td[not(img)]/following-sibling::td[@class,'ID']
But it's not working...
I am able to find td via xpath .//td[not(img)], but when I add condition for ID, then I see all td, no matters if is with img or not.
Maybe there is a simple solution which I could not find.
Please help me.

To get all td elements having no img child elements you can use this XPath:

//td[not(.//img)]

BTW, your XML here is invalid.
It should be something like this:

<tbody>
    <tr>
    <td >
       <img src="lock.img" alt="Row locked"></img>
    </td>
    <td >
    </td>
    <td >
    </td>
    <td >
    </td>
      </tr>
</tbody>

If I understand you correctly your xml could look like this:

<?xml version="1.0" encoding="UTF-8"?>
<tbody>
  <tr>
    <td >
      <img src="lock.img" alt="Row locked"/>
      I should NOT be found
    </td>
    <td >I should NOT be found</td>
    <td >I should NOT be found</td>
    <td >I should be found</td>
    <td >I should NOT be found</td>
    <td >I should be found</td>
    <td >
      <img src="lock.img" alt="Row locked"/>
      I should NOT be found
    </td>
    <td >I should NOT be found</td>
    <td >I should NOT be found</td>
    <td >I should be found</td>
  </tr>
</tbody>

.//td[not(img)] selects also the td with @class='ID' .

To only select the td with @class='LOCK' use .//td[@class='LOCK'][not(img)]

following-sibling::td[@class,'ID'] selects all the following siblings with @class='ID'.

To get only the first add an extra [1] to tell to only to use the first. (It is the shorthand for [position()=1])

The XPath would then be:

.//td[@class='LOCK'][not(img)]/following-sibling::td[@class='ID'][1]

This will select the rows with the text 'I should be found'
