Cross-Links Creation using xslt - xslt-3.0

Question

I would like to give cross-links in the below XML using XSLT 3.0.
My Input XML is:
<?xml version="1.0"?>
<book id="bk1">
<p>The heterogeneity of patients, various clinical manifestations and the dynamics of CS development cause problems with identifying its unified definition. However, CS can be usually diagnosed on the basis of clinical criteria which are easy to assess without the need for advanced hemodynamic monitoring Thiele et al., 2015. Increasing knowledge about (Perkins-Porras et al., 2009) patient characteristics and better understanding of the CS pathophysiology encourages researchers and clinicians to revise the classic definition. (Thiele et al., 2015; Werdan et al., 2012; Nadziakiewicz et al., 2007; Sobanski et al., 2010; Goldberg et al., 2009; Harjola et al., 2015; Holmes et al., 1995).</p>
</book>
Expected Output XML is:
<?xml version="1.0"?>
<book id="bk1">

</book>
If author name with et al or author name without et al also need to check and give tag. How to achieve this?

Answer 1

Matching on "names" is always difficult so the following might work for some examples but not for others:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:fn="http://www.w3.org/2005/xpath-functions"
exclude-result-prefixes="#all"
version="3.0">
<xsl:param name="author-pattern" as="xs:string">(\p{Lu}[\p{L}-]+)( et al.)?, ([0-9]{4})</xsl:param>
<xsl:mode on-no-match="shallow-copy"/>
<xsl:template match="p//text()">
<xsl:apply-templates select="analyze-string(., $author-pattern)" mode="wrap-authors"/>
</xsl:template>
<xsl:template match="fn:match" mode="wrap-authors">
<a href="#bib{fn:group[#nr = 1]}{fn:group[#nr = 3]}">
<xsl:apply-templates mode="#current"/>
</a>
</xsl:template>
</xsl:stylesheet>
