Ranorex is a proprietary alternative to Selenium. To select an element, they’re using the so-called RanoreXPath. Both, RanoreXPath and XPath, are pretty similar in their syntax, but are different in following areas:

 

 

Feature	RanoreXPath (Ranorex)	Xpath (Selenium)	Description
Text contains a certain pattern	/dom[@domain='federations.gfk.com']//*[@id~'email']	.//*[contains(@id,'email')]	RanorexPath uses ~ to start a Regex, which is a substitute for Xpath's contains()-function: http://www.ranorex.com/support/user-guide-20/ranorexpath.html#c3294
Tab-Location	Prefix /dom[@page='FlexExample.html'] to recognize the browsertab.	No prefix, as the browser-tab is selected by code: driver.get(http://www.google.de);	Ranorex doesn't need the prefix, but it's strongly recommanded to use it for two reasons: 1. Without the prefix, Ranorex climbs down each and every window to search for an element, which matches the RanoreXPath - and that may be very time-consuming! 2. Think of two opened browsers with elements recognized by the same RanoreXPath - those situations cause non-deterministic behaviour, which is hard to debug.
Driver of the language-power	Regex	Functions	To cope with the special-cases of recognizing UI-elements, you need a powerful language.
Make the paths case-insensitive	i:	Translate()	Case-insensitivity in Xpath: http://stackoverflow.com/a/586260/1777526
Selecting the x-th element, that match the path	/dom[@domain~'mydomain']//div[@class='header'][2]	(.//div[@class='header'])[2]
Locate svg-elements	/dom[@domain~'mydomain']//tag[@TagName='rect'][13]	(//*[local-name()='rect'])[13]
quotes	only single quotes allowed	single and double quotes allowed
Multiple Element matches	Decides with a certain algorithm, which element will be selected	If more than one element match the XPath, the first in the DOM is selected
Return of text	The inner text of a certain element is returned	The concatenated text of all descendant elements is returned
