How do I fix this XSLT that stopped working? - xslt-2.0

Question

I have this XSLT that Marting Honnen graciously supplied (link)
The template stopped working for some reason and I can't seem to fix it. The data expanded but I don't see how that should matter.
Instead of turning the double pipe delimited text into xml; it just deletes the delimited data
Here's the template and sample data:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="str">
<xsl:copy>
<xsl:apply-templates select="#*"/>
<xsl:analyze-string select="." regex="\|((\|[^|]+\|)+)\|">
<xsl:matching-substring>
<xsl:analyze-string select="regex-group(1)" regex="\|(\w+):([^|]+)\|">
<xsl:matching-substring>
<xsl:element name="{regex-group(1)}">
<xsl:value-of select="regex-group(2)"/>
</xsl:element>
</xsl:matching-substring>
</xsl:analyze-string>
</xsl:matching-substring>
<xsl:non-matching-substring>
<xsl:value-of select="."/>
</xsl:non-matching-substring>
</xsl:analyze-string>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

Can I use XSLT to transform this XML into this?

Some of your colon separated fields have leading and trailing white space (e.g. | background:n/a |) so the regular expressions needs some tuning:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="str">
<xsl:copy>
<xsl:apply-templates select="#*"/>
<xsl:analyze-string select="." regex="\|((\|\s*[^|]+\s*\|)+)\|">
<xsl:matching-substring>
<xsl:analyze-string select="regex-group(1)" regex="\|\s*(\w+):([^|]+?)\s*\|">
<xsl:matching-substring>
<xsl:element name="{regex-group(1)}">
<xsl:value-of select="regex-group(2)"/>
</xsl:element>
</xsl:matching-substring>
</xsl:analyze-string>
</xsl:matching-substring>
<xsl:non-matching-substring>
<xsl:value-of select="."/>
</xsl:non-matching-substring>
</xsl:analyze-string>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
Using that stylesheet on your posted input Saxon 9.5 outputs
