Unexpected behaviour for assertSeeIn()

[benr77]

I keep getting annoyed when using assertSeeIn() as the CSS selection often does not do what I expect.

Say I have a table in my page:

<tr>
    <td>Foo</td>
    <td>Bar</td>
</tr>

If I want to check that Bar is present, I would expect to be able to use:

$this->assertSeeIn('td', 'Bar').

This will work for Foo as it's the first td that the crawler will encounter, but to match Bar I have to use:

$this->assertSeeIn('tr td:last-child', 'Bar')

I expect assertSeeIn to find a string in ANY element that matches the $selector.

Is this the expected/desired behaviour? If so then something in the docs about it would be good, but personally I don't think it's the right behaviour - I don't want to couple my tests so tightly to the exact HTML - in this case I just want to check the Bar is shown somewhere in the table, I don't care about its exact position.

Any thoughts?

Cheers
