Combining input XML to produce another XML output - xslt

Question

Trying to build a POC that does the following:
Given a short input XML, take the values from it and insert them into a larger XML file of a known format.
So if this was my input XML:
<root>
<transaction ID="TX123" source-system="xyz" timestamp="2015-10-15T14:20:35.954Z" dest-system="abc" status="success" applicationID="some_app" originator="MQ">
</transaction>
</root>
And i'd have to take these values and insert them into this: MQ FTE Transfer Log message format
I'd have to insert the values in the transferSet node (timestamp) and metaDataSet.
What would the XSLT have to look like in order to get this done?
Thanks a bunch in advance!

Your XLS should look like this:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/root">
<transaction>
<!-- more elements... -->
<xsl:apply-templates select="transaction"/>
</transaction>
</xsl:template>
<xsl:template match="transaction">
<transferSet>
<xsl:attribute name="startTime"><xsl:value-of select="#timestamp" /></xsl:attribute>
<metaDataSet>
<metaData key="com.ibm.wmqfte.SourceAgent"><xsl:value-of select="#source-system"/></metaData>
<!-- more elements... -->
</metaDataSet>
</transferSet>
</xsl:template>
With your source input, it should generate an XML like this:
<?xml version="1.0" encoding="UTF-8"?>
<transaction>
<transferSet startTime="2015-10-15T14:20:35.954Z">
<metaDataSet>
<metaData key="com.ibm.wmqfte.SourceAgent">xyz</metaData>
</metaDataSet>
</transferSet>
</transaction>
