Introduction
I had a recent requirement where I was mapping data from a API to a target API. The API would return a empty tag for a field that has no value, and that would mean my mapping would also create a empty tag. This meant that my target XML also had a empty tag and that was not needed.
XSLT Mapping
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<!-- Identity transform -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<!-- Ignore empty text nodes -->
<xsl:template match="text()[normalize-space()='']"/>
<!-- Ignore nodes with only empty nodes or attributes -->
<xsl:template match="*[not(*|@*|text()[normalize-space()])]"/>
<!-- Ignore nodes with only empty children -->
<xsl:template match="*[not(node()[normalize-space()]) and not(text()[normalize-space()]) and not(@*[normalize-space()])]"/>
</xsl:stylesheet>
