XSLT 1.0 is Turing-complete so the theoretical answer is yes. (With a
proviso that you would need to call out to extensions to handle a few things
like unparsed-text() and xsl:result-document).

The practical answer, given the number of man-years that I imagine are
available to you, is no. Can you imagine what a regular expression engine
would look like written in XSLT 1.0 code?
