Last Updated : 03 Oct, 2023

XSLT <if> Element is used to check the condition of the content of XML. The test is used to check the condition if it satisfies the condition then inside if is executed.

Syntax:

<xsl:if test=EXPRESSION>
  // Some output if the expression is true
</xsl:if>

Parameters:

test: It is the condition that will check on the content of XML.

Example 1: In this example, we will use the <xsl:if> tag to only show the CSE student in the table. Save Both files as mentioned and open xsl file on the Browser, it will show the output as shown below:
