Use XSLT to convert delimited text to XML - xslt-1.0

Question

I have some double pipe delimited data inside some XML tags and I would like to replace/convert the delimited text to XML.
The delimited text also uses a colon to separate the heading and the data, like so: ||tagname:data||
The headings or tag names could be anything, this is just one example. So I don't know in advance what I'm getting. I must take what's listed in front of the colon and use that.

Can I use XSLT to transform this XML into this?

The URLs will have to be wrapped in CDATA and the delimited version will have to be replaced.
Can someone point me in the right direction?
Thank you,

analyze-string can help, with Saxon 9.5 the stylesheet
<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: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>
transforms the input

into the result
