Subject: avoiding nil.methodcalls short and cheap

Hi,

I often have to check if a methodcall A is not returning nil before
calling another method on the return value of the methodcall A. I'm
looking for a short and cheap (avoiding to call method A two times like
in this example where xmltag.get_text is method A:
textvalue = xmltag.get_text.value if xmltag.get_text
)
The ideal solution would be a oneliner with only little complexity
calling method A just one time. Am I using the wrong approach here
anyway?

Thanks,
.tr!
