Get xpath under particular tag - selenium

Question

Am newbie to selenium (java).
I have to click on the menu item which is under <ul> tag as <li> items. I can able to get it with //*[#id='MainMenu']/li[5]/span xpath.
I do not want to hard code [5] of the list item, because item's position may change. It may not at 5th position all the time.
I wanted to get xpath for the particular item under particular tag with an id.
Edit:
This is how my html looks like. List item text will be loading dynamically.
<ul id="sfMainMenu" class="sf-menu ui-selectable">
<li class="ui-selected ui-selectee">
<span subnav="0" param="cmd=desk" filesrc="/Dashboard/Index"></span>
</li>
<li class="ui-selectee"></li>
<li class="ui-selectee"></li>
<li class="ui-selectee"></li>
<li class="ui-selectee">
<span subnav="18" param="cmd=desk" filesrc="../myFile.aspx"></span>
</li>
</ul>
Kindly suggest the approach with an example.

Answer 1

I suggest trying this:
//*[#id='MainMenu']/li[normalize-space() = 'The text you want']/span
Though if you could show us what the HTML in question actually looks like, we can provide a more reliable answer. XPath doesn't have any concept of "visual text", so if you have some text that's hidden within the li you're trying to retrieve, that could be considerably trickier.

Answer 2

I have solved by using filesrc attibute of span tag in the list item.
Xpath is:
//span[contains(#filesrc, 'myFile.aspx')]
As my .aspx file will be the same for any page, so I used filesrc attribute which contains the actual file name and is the only file name in that html page.

You can use the following
driver.FindElement(By.XPath("//li[contains(Text(),'Expected Text']")).Click();
Or you can avoid xpath all together by running a foreach loop on the relevant Class tag
foreach (IWebElement e in driver.FindElements(By.ClassName("ui-selectee")))
{
if (e.Displayed && e.Text == "Expected Text")
e.Click();
}
