My (simplified) input XML looks like this:
<?xml version="1.0" encoding="utf-8"?>
<root>
<recordList>
<record>
<id>16</id>
<MaterialGroup>
<material>
<term>metal, glass</term>
</material>
<material.notes />
<material.part>body</material.part>
</MaterialGroup>
<MaterialGroup>
<material>
<term>wood</term>
</material>
<material.notes>fragile</material.notes>
<material.part>lid</material.part>
</MaterialGroup>
</record>
<record>
...
</record>
</recordList>
</root>
Note that term may contain a comma-separated list of multiple materials (metal, glass).
Desired output:
I want to split the material/term and need to duplicate the grandparent Material with all attributes and nodes for that.
<?xml version="1.0" encoding="utf-8"?>
...
<MaterialGroup>
<material>
<term>metal</term>
</material>
<material.notes />
<material.part>body</material.part>
</MaterialGroup>
<MaterialGroup>
<material>
<term>glass</term>
</material>
<material.notes />
<material.part>body</material.part>
</MaterialGroup>
<MaterialGroup>
<material>
<term>wood</term>
</material>
<material.notes>fragile</material.notes>
<material.part>lid</material.part>
</MaterialGroup>
</record>
...
The first MaterialGroup is copied for every token in the delimited grandchild element material/term, and the term text is set to the token text. material.parts and material.notes can be copied unchanged.
My stylesheet:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"

<xsl:output method="xml" indent="yes"/>
<xsl:variable name="separator" select="','"/>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="material/term" mode="s">
<xsl:param name="split_term"/>
<xsl:value-of select="$split_term"/>
</xsl:template>
<xsl:template match="MaterialGroup" name="tokenize">
<xsl:param name="text" select="material/term"/>
<xsl:choose>
<xsl:when test="not(contains($text, $separator))">
<xsl:copy>
<xsl:apply-templates/>
<xsl:apply-templates select="material/term" mode="s">
<xsl:with-param name="split_term">
<xsl:value-of select="normalize-space($text)"/>
</xsl:with-param>
</xsl:apply-templates>
</xsl:copy>
</xsl:when>
<xsl:otherwise>
<xsl:copy>
<xsl:apply-templates/>
<xsl:apply-templates select="material/term" mode="s">
<xsl:with-param name="split_term">
<xsl:value-of select="normalize-space(substring-before($text, $separator))"/>
</xsl:with-param>
</xsl:apply-templates>
</xsl:copy>
<xsl:call-template name="tokenize">
<xsl:with-param name="text" select="substring-after($text, $separator)"/>
</xsl:call-template>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
Actual output:
<?xml version="1.0" encoding="utf-8"?>
<root>
<recordList>
<record>
<id>16</id>
<MaterialGroup>
<material>
<term>metal, glass</term>
</material>
<material.notes />
<material.part>body</material.part>
metal
</MaterialGroup>
<MaterialGroup>
<material>
<term>metal, glass</term>
</material>
<material.notes />
<material.part>body</material.part>
glass
</MaterialGroup>
<MaterialGroup>
<material>
<term>wood</term>
</material>
<material.notes>fragile</material.notes>
<material.part>lid</material.part>
wood
</MaterialGroup>
</record>
<record>
...
</record>
</recordList>
</root>
The tokens (metal, glass) occur as text elements as MaterialGroup children, below material.parts. The text element where it should actually appear (material/term) is unchanged.
I looked at couple solutions to similar problems, but no success:

Any ideas?

I think you need to pass your term around:
That way, with your input, I get
