title: Appium:How can I search an element using regex
body: <p>I am using Appium for automating my desktop WPF application (build in C# .Net).
  My automation is idenitfying the WPF application window by its name , which is dynamic. For ex: The application window name is "ABC1.0.0" Where ABC will be constant but 1.0.0, which is the version, will vary.
  Currently if I hardcode the name to "ABC1.0.0" then findelementbyname works and window gets identified but I just wanted to check if there a way to use regular expression to identify my window without hardcoding ? Note: Xpath wont work for our desktop app.
  For ex: Something like this:
  FindElementByName("ABC.*")</p>
