Selenium.IsElementPresent using a Select Option's text (C#)

Question

I'm using Selenium in C# with Selenium RC to do some automated interaction testing but have come across a stumbling block.

Given this HTML:

<select id="my-select-list">
    <option value="1">First option</option>
    <option value="2">Second option</option>
    <option value="3">Third option</option>
    <option value="4">Fourth option</option>
</select>

I want to test to make sure that the option "Third Option" is present on the page.

All of the following tests have failed, i.e. return false:

Selenium.IsElementPresent("//select/option[@label='Third option']")
Selenium.IsElementPresent("//select[option='Third option']")
Selenium.IsElementPresent("//select[contains(option, 'Third option')]")
Selenium.IsElementPresent("//option[contains(., 'Third option')]")
Selenium.IsElementPresent("//option[contains(text(), 'Third option')]")

Is it a limitation of Selenium (RC / .NET) or is there another way of selecting it?

Ps. I know I could test using the option's value but that may change and the text definately won't.

EDIT: PEBKAC error

Sorry, my bad. Seems selenium was loading a different site than what I thought it was loading.

The following XPath queries all work:

Selenium.IsElementPresent("//option[text()='Third option']")
Selenium.IsElementPresent("//select[option='Third option']")
Selenium.IsElementPresent("//option[contains(., 'Third option')]")
Selenium.IsElementPresent("//option[contains(text(), 'Third option')]")

Answer 1

My XPath's a bit rusty, but have you tried...

Selenium.IsElementPresent("//option[text()='Third option']");
