I want to transform custom xml that has been tagged with unique identifiers into MARCXML, but I have no idea where to start. For example, I need to take <untl:title qualifier="officialtitle" >Equation of State and Heat Content of Uranium</untl:title> and assign it to a 245 field. Here is my attempt at pulling the title, but I do not know where to specify which qualifier to use to pull from the correct element. My understanding of XSLT is very sparse and any help is greatly apreciated.
<xsl:for-each select="untl:title"><datafield tag="245" ind1="1" ind2="0">
<subfield code="a">
<xsl:value-of select="."/>
</subfield>
</datafield>
</xsl:for-each>
Edit(8/17/2020):I'm using a program called MarcEdit and he has created presets of XSLT sheets that I believe can be modified for UNTL, however I don't have the knowledge or expertise currently to customize them. You'll see the target structure sheet, my current code, and the preset XSLT I'm using as a reference below.
Code so Far: Not alot, really trying to nail down Namespaces for the UNTL. From reading online, my understanding of the xsl:import is that it will allow the target stucture (MARC21slimUtils) to be imported into my current XSL file?.

<xsd:documentation> MARCXML: The MARC 21 XML Schema Prepared by Corey Keith May 21, 2002 - Version 1.0 - Initial Release ********************************************** Changes. August 4, 2003 - Version 1.1 - Removed import of xml namespace and the use of xml:space="preserve" attributes on the leader and controlfields. Whitespace preservation in these subfields is accomplished by the use of xsd:whiteSpace value="preserve" May 21, 2009 - Version 1.2 - in subfieldcodeDataType the pattern "[\da-z!"#$%&'()*+,-./:;<=>?{}_^`~\[\]\\]{1}" changed to: "[\dA-Za-z!"#$%&'()*+,-./:;<=>?{}_^`~\[\]\\]{1}" i.e "A-Z" added after "[\d" before "a-z" to allow upper case. This change is for consistency with the documentation. ************************************************************ This schema supports XML markup of MARC21 records as specified in the MARC documentation (see www.loc.gov). It allows tags with alphabetics and subfield codes that are symbols, neither of which are as yet used in the MARC 21 communications formats, but are allowed by MARC 21 for local data. The schema accommodates all types of MARC 21 records: bibliographic, holdings, bibliographic with embedded holdings, authority, classification, and community information. </xsd:documentation>

I think this will get you started. It shows how to output field 100 (the author):
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:untl="http://digital2.library.unt.edu/untl/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.loc.gov/MARC21/slim"
exclude-result-prefixes="untl"
>
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*" />
<xsl:template match="/">
<collection xsi:schemaLocation="http://www.loc.gov/MARC21/slim http://www.loc.gov/standards/marcxml/schema/MARC21slim.xsd">
<xsl:apply-templates select="record" />
</collection>
</xsl:template>
<xsl:template match="record">
<record>
<xsl:apply-templates select="metadata/untl:metadata" />
</record>
</xsl:template>
<xsl:template match="untl:metadata">
<!-- add more <xsl:apply-templates> in the desired field output order -->
<xsl:apply-templates select="untl:creator[@qualifier='aut']" />
</xsl:template>
<!-- write one template for each field -->
<xsl:template match="untl:creator[@qualifier='aut']">
<datafield tag="100" ind1="1" ind2=" ">
<subfield code="a">
<xsl:value-of select="untl:name" />
<xsl:text>,</xsl:text>
</subfield>
</datafield>
</xsl:template>
</xsl:stylesheet>
I've deliberately used one template per node, so you can see how the program flows from the root node of the input (/) and then continues to select specific nodes that each have their own templates.
I don't think you will need to include the MARC21slimUtils.xsl at all - I've looked at it and the utility functions in there add no real value in this case.
Output (aligned with the official MARCXML sample), formatted for readability:
<collection xmlns="http://www.loc.gov/MARC21/slim"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.loc.gov/MARC21/slim http://www.loc.gov/standards/marcxml/schema/MARC21slim.xsd"

<record>
<datafield tag="100" ind1="1" ind2=" ">

I'm not sure about the specifics, such as the trailing commas in the author's names, or the significance of ind1 and ind2, you will understand these things better than I do.
