XSLT <xsl:import> element is used to include the content of one stylesheet within another. When you import a stylesheet, it allows you to incorporate the templates, definitions, and other components from the imported stylesheet into the importing stylesheet.
Syntax:
<xsl: import href=URI>
</xsl:import>
Parameters:
- URI: It is the path of the XSLT style that we want to import.
Example 1: In this example, we will import the third.xsl style sheet which prints the student details in table format.
XML
<!--first.xsl:--> <?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl href="Third.xsl" ?>
<student>
<s>
<name> Divyank Singh Sikarwar </name>
<branch> CSE</branch>
<age>18</age>
</s>
<s>
<name> Aniket Chauhan </name>
<branch> CSE</branch>
<age> 20</age>

Example 2: In this example we will import another style sheet which prints the student details in list format.
