<xsl:template match="title">
    <title>
      <xsl:sequence select="serialize(node()) => substring-before(':') => lower-case() => parse-xml-fragment()" />
    </title>
    <subtitle>
      <xsl:sequence select="serialize(node()) => substring-after(':') => lower-case() => parse-xml-fragment()" />
    </subtitle>
  </xsl:template>

gives

<title>the title of the book with some <i>italics</i> and some more words</title>
<subtitle> the subtitle of the book with some <i>italics</i></subtitle>

That's XSLT 3.0, it assumes there's always a colon, and could be made
rather more robust, but that's the general idea; treat the contents of
the element as a string sometimes and as nodes sometimes.
