How to click at a control and if it is not there not to stop the script?

Hi I am a very brand new newbie:D 
Cannot figure out:
I have a few dynamically created controls like: //a[contains(text(),'custom_cm_plugins')]
I need to click at them one by one and if one of them is not present just give a warning, not to stop the script and continue further.
I have for now:
clickAndWait - //a[contains(text(),'custom_cm_plugins')]

and it stops it the control is not there.
What should I do?

Thanks

You need to use IF condition. Search on net for IF-WHILE conditions with selenium, and you will get a js file. Follow the instructions and IF condition will be there in your selenium.

Then you just need to verify that element. Like If particular element is present then click on it.
