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.
