comparing element using XSLT dynamically

I have XML document something like below.

<root>
    <Book>
        <Book_title/>
        <author_name/>
    </Book>
    <Book>
        <Book_title/>
        <author_name/>
    </Book>
    <author_details>
        <author_name/>
        <author_DOB/>
    <author_details/>
</root>

So can we compare Book/author_name with author_details/author_name dynamically with XSLT ...??

Define a key

<xsl:key name="author" match="author_details" use="autor_name"/>

then write a template for

<xsl:template match="Book/author_name">
  <xsl:copy-of select=". | key('author', .)/author_DOB"/>
</xsl:template>

handle root and Book by the identity transformation (e.g. <xsl:mode on-no-match="shallow-copy"/> in XSLT 3) and add an empty

<xsl:template match="author_details"/>

to prevent copying/outputting those elements.
