How to deal with parentheses in a text node in xpath? - xpath

Question

Say we have the following HTML code
<label for="467578">AgendaShowCapacity (1 remaining)</label>
I tried with the following xpath expression in Chrome but can't locate to that element:
//label[text()='AgendaShowCapacity (1 remaining)']
I was wondering whether the parenthese is to be blamed for this. If it is, how should I deal with it under such situation?
Any comments would be appreciated, thanks!

</div>
</li>
</ol>
</fieldset>
<div class="buttonGroup">
<button type="button" name="ctl00$cph$ctlNavigation$btnAddAnother" class="button" onclick="SubmitForm(this);return false;">Add Another Person</button>
<span class="textBetweenButtons">or</span>
<button type="submit" name="ctl00$cph$ctlNavigation$btnContinue" class="button" onclick="SubmitForm(this);return false;">Continue</button>
</div>
</div>
Here is the essential part of the html page in which I want to locate to that //label element.

Sample C# code using selenium-webdriver to locate that element.
IWebDriver driver = new FirefoxDriver();
IWebElement = driver.FindElement(By.XPath("//div[#id='pageContent']//legend/following-sibling::ol/li/div/label[text()='AgendaShowCapacity (1 remaining)']"));
// Do something to that element
