Unable to Detect Dynamic form ID in webdriver

I am trying to detect dynamic form ID using webdriver.
In selenium IDE I got command like Selectframe , Target= "CitrixUI_hkkji" so target is dynamically generated with CitrixUI_ as a comman part
SO in selenium webdriver i write command driver.switchto().frame("CitrixUI_hkkji") , but as this target is dynamic so not detectable.
Is there any solution for this?

Value of target in IDE is "CitrixUI_hkkji" , but it is not mentioned that whether it is ID/name/css/xpath . So how to solve this problem ? Can I use regular expression in this case? If yes please provide any example

Value of target in IDE is "CitrixUI_hkkji" , but it is not mentioned that whether it is ID/name/css/xpath

It is id.

Can you try with this xpath:

Code:

"//frame[contains(@id, 'CitrixUI')]"

You can use other locators as parameter: http://pear.php.net/package/Testing_Selenium/docs/latest/Selenium/Testing_Selenium.html#methodselectFrame
