Shouldn't it suffice to do

    <xsl:analyze-string select="'a:b;c:d;'"
                        regex="([a-z]):([a-z]);">
      <xsl:matching-substring>
        <!-- now access groups here -->
      </xsl:matching-substring>
    </xsl:analyze-string>

then matching-substring is "called" for every part of the form "x:y;".
