Can XPath (Parser) Parse within Elements?

I cannot figure out if I can get information out of elements, not the entirety of the element with this module.

Like if an element is this:

<abc>Another name for this: XYZ</abc>

And I just want to map whatever appears after the : to a field.

Is this possible? If not w/ Feeds XPath Parser, in conjunction with another module?

Or is this outside of XPath altogether, to parse within elements?

Okay thanks!
