Start with an identity template that copies everything:

<xsl:template match="*">
  <xsl:copy><xsl:copy-of select="@*"/><xsl:apply-templates/></xsl:copy>
</xsl:template>

Add a template rule that doesn't copy such elements:

<xsl:template match="Product[starts-with(@code, 'TT')]"/>

Add another template rule:

<xsl:template match="Category[not(Product[not(starts-with(@code, 'TT))])]"/>
